Description

Light emitting diode lamp string system with sequencing function and sequencing method

The invention relates to a light emitting diode lamp string system and method, in particular to a light emitting diode lamp string system with sequencing function and a sequencing method.

A related-art light-emitting diode lamp string system includes a related-art light-emitting diode drive device and a related-art light-emitting diode lamp string; the related-art light-emitting diode lamp string includes a plurality of related technology Light-emitting diode lamps. The related art light-emitting diode lamps are electrically connected to each other. After the manufacturing of the related-art light-emitting diode lamp strings is completed, each of the related-art light-emitting diode lamps has a status address code, and the original positions of the related-art light-emitting diode lamps The address codes are different, and the light-emitting diode lamps of the related technologies are sequentially arranged according to the local address codes; for example, assume that the light-emitting diode lamp string of the related technology includes 25 lights of the related technologies Diode lamps, the 25 related-art light-emitting diode lamps have the local address codes of 01, 02...25, respectively, and the 25 related-art light-emitting diode lamps are sequentially in accordance with these The local address code 01, 02...25 is set.

The related-art light-emitting diode driving device is used to drive the related-art light-emitting diode lamp string to emit light in various ways, as follows: First, the related art light emitting diode driving device generates a related art driving light emitting signal, wherein the related art driving light emitting signal includes a preset address code and a light emitting code; then, the related art light emitting diode The body driving device transmits the driving light signal of the related technology to the light emitting diode lamps of the related art, and all the light emitting diode lamps of the related technology will receive the drive light signal of the related technology. If the local address code of the related art light emitting diode lamp is the same as the preset address code of the related art driving light signal, the related art light emitting diode lamp emits light according to the related art drive The light-emitting code of the signal emits light; if the local address code of the light-emitting diode lamp of the related art is different from the preset address code of the drive light-emitting signal of the related art, the light-emitting diode of the related art The lamp ignores the light emitting code of the related art driving light emitting signal.

For example, if the preset address code of the driving light signal of the related technology is 05, the related art light emitting diode lamp with the local address code of 05 will emit light according to the driving light signal of the related technology The code emits light, and the other related-art light-emitting diode lamps ignore the light-emitting code of the related art driving light-emitting signal. Therefore, the related art light emitting diode driving device can drive the related art light emitting diode lamp string to emit light in a diversified manner.

When a light-emitting diode lamp of a related technology is damaged, the light-emitting diode lamp of the related technology will not emit light, and the user will purchase a new light-emitting diode lamp of the related technology and use the new related The light emitting diode lamp of the technology replaces the damaged related art light emitting diode lamp. For example, when the related art light emitting diode lamp with the home address code of 05 is damaged, the user will purchase a new related technology light emitting diode lamp (for example, the home address code is 30), And replace the damaged related-art light-emitting diode lamp (the local address code is 05) with the new related-art light-emitting diode lamp (the local address code is 30).

However, the related-art light-emitting diode driving device does not know that the new related-art light-emitting diode lamp (the local address code is 30) has replaced the damaged related-art light-emitting diode lamp (the original The status address code is 05), so that when the related art light emitting diode driving device transmits the related art driving light emitting signal with the preset address code of 05 to the related art light emitting diode lamps, No light-emitting diode lamp of any related technology will emit light according to the light-emitting code.

Therefore, when the related art light emitting diode lamp with the local address code 05 is damaged, the user can only purchase a new related art light emitting diode lamp with the local address code 05, And replace the damaged light-emitting diode lamp of the related art with the home address code 05 with the new light-emitting diode lamp of the related art with the home address code 05; or, the user only A new light-emitting diode lamp string of the related technology can be purchased to replace the original light-emitting diode lamp string of the related technology, in which the original address of the related art light-emitting diode lamp string The related art LED lamp with code 05 is damaged. The user cannot arbitrarily purchase the related art light emitting diode lamp with the local address code of unknown (or not 05) to replace the damaged related art light emitting diode lamp with the local address code of 05.

In this disclosure, many specific details are provided to provide a thorough understanding of specific embodiments of the present invention; however, those skilled in the art should be aware that in the absence of one or more of these specific details, The invention can be practiced; in other cases, well-known details are not shown or described to avoid obscuring the main technical features of the invention. The technical content and detailed description of the present invention are described below in conjunction with the drawings: Please refer to FIG. 1, which is a block diagram of an embodiment of a sequenced light-emitting diode lamp string system of the present invention (parallel type) . A light emitting diode lamp string system 10 with a sequencing function is applied to an AC power supply device 20; the light emitting diode lamp string system 10 with a sequencing function includes a light emitting diode driving device 102 and at least one LED string 104; the LED driving device 102 includes a transmitter controller 108, a transmitter switch 110, a transmitter memory 112, a test button 114, a current detector 116, a An RF receiver 118, a DC-DC converter 120, an AC-DC converter 122, and a first connector 168; the at least one LED lamp string 104 includes a plurality of LED lamps 106, a second A connector 170 and a third connector 172; the above components are electrically connected to each other, and the light emitting diode lamps 106 are electrically connected to each other (ie, connected in parallel), and the second connector 170 is Connect (eg, plug) to the first connector 168. The sender memory 112 can also be integrated with the sender controller 108 into a memory-containing controller.

After the at least one LED lamp string 104 is manufactured, each of the LED lamps 106 has a local address code, and the local address codes of the LED lamps 106 are different , And the light-emitting diode lamps 106 are sequentially set according to the local address codes; for example, assume that At least one light emitting diode lamp string 104 includes 25 of the light emitting diode lamps 106, the 25 light emitting diode lamps 106 respectively have the local address codes of 01, 02...25, and the 25 The light-emitting diode lamp 106 is sequentially arranged from left to right in FIG. 1 according to the local address codes 01, 02...25.

The at least one light emitting diode lamp string 104 is connected to the light emitting diode driving device 102 through the first connector 168 and the second connector 170, and the light emitting diode driving device 102 is used to drive the At least one light emitting diode lamp string 104 emits light in various ways. The method is as follows: the transmitter controller 108 controls the transmitter switch 110 (on or off) to generate a driving light signal, wherein the driving light signal includes a pre Set an address code and a light-emitting code; then, the light-emitting diode drive device 102 transmits the drive light-emitting signal to the light-emitting diode lamps 106, all of the light-emitting diode lamps 106 will receive the drive light signal. If the local address code of the light emitting diode lamp 106 is the same as the preset address code of the driving light emitting signal, the light emitting diode lamp 106 emits light according to the light emitting code of the driving light emitting signal; if the light is emitted The local address code of the diode lamp 106 is not the same as the preset address code of the driving light signal, then the light emitting diode lamp 106 ignores the lighting code of the driving light signal; the above content can be called Point control technology.

For example, if the predetermined address code of the driving light-emitting signal is 05, the light-emitting diode lamp 106 with the local address code of 05 will emit light according to the light-emitting code of the driving light-emitting signal, and the rest of the light-emitting The diode lamp 106 ignores the light emitting code of the driving light emitting signal. Therefore, the light emitting diode driving device 102 can drive the at least one light emitting diode lamp string 104 to emit light in various ways.

When a light-emitting diode lamp 106 is damaged, the damaged light-emitting diode lamp 106 will not emit light, and the user will purchase a new light-emitting diode lamp 106, and use the new light-emitting diode lamp 106 replaces the damaged LED lamp 106. For example, when the LED lamp 106 with the local address code 05 is damaged, the user will purchase a new LED lamp 106 (for example, with the local address code 30) and use The new light emitting diode lamp 106 (having the local address code of 30) replaces the damaged light emitting diode lamp 106 (having the local address code of 05).

As a result, two problems arise:

1. How does the light-emitting diode driving device 102 know that the light-emitting diode lamp 106 with the local address code of 05 is damaged (removed)?

2. How does the LED driving device 102 know that the local address code of the new LED lamp 106 is 30?

If the light emitting diode driver 102 learns that the light emitting diode lamp 106 with the local address code of 05 is removed, and if the light emitting diode driver 102 learns a new light emitting diode lamp The local address code of 106 is 30, and the next time the light emitting diode driving device 102 wants to drive the light emitting diode lamp 106 with the local address code of 05 to emit light, the preset position of the driving light signal The address code will become 30 (not 05).

In response to the first problem mentioned above, the present invention provides a preset sequential test mode to help the light emitting diode driving device 102 to find the damaged (removed) light emitting diode lamp 106. The content is as follows: First, the test button 114 is pressed, so that the light emitting diode driving device 102 enters the preset sequence test mode. When the LED driving device 102 is in the preset sequence test mode: the LED driving device 102 generates a plurality of preset sequence test signals, wherein each of the predetermined sequence test signals has the preset bit Address codes, and the predetermined address codes are different; according to a test sequence of the predetermined address codes, the light emitting diode driving device 102 sequentially transmits the predetermined sequence test signals to the at least one light emitting The light emitting diode lamps 106 of the diode lamp string 104, and correspondingly and sequentially detect the current consumption of one of the at least one light emitting diode lamp string 104; when the current consumption is less than or equal to a first current ( For example, 0mA or 0.001mA), the LED driving device 102 stores and defines the predetermined address code corresponding to the predetermined sequence test signal of the current consumption less than or equal to the first current as a failure address code . In this way, the light emitting diode driving device 102 can know which light emitting diode lamp 106 is damaged (removed).

For example, the predetermined sequence test signals respectively have the predetermined address codes of 01, 02...25, and the test sequence is 01, 02...25; first, the light emitting diode driving device 102 transmits the predetermined sequence The predetermined sequence test signal with the address code 01 to the light-emitting diode lamps 106 of the at least one light-emitting diode lamp string 104; at this time, the light-emitting diode lamp with the local address code 01 106 emits light to generate the current consumption (greater than the first current), so the light-emitting diode driving device 102 knows that the light-emitting diode lamp 106 with the local address code 01 is normal.

Then, the LED driving device 102 transmits the predetermined sequence test signal with the predetermined address code of 02 to the LED lamps 106 of the at least one LED lamp string 104; , The light-emitting diode lamp 106 with the local address code 02 will emit light to generate the current consumption (greater than the first current), so the light-emitting diode drive device 102 learns that the local address code is 02 The LED lamp 106 is normal.

And so on, until the light emitting diode driving device 102 transmits the preset sequence test signal with the preset address code of 05 to the light emitting diode lamps 106 of the at least one light emitting diode lamp string 104 Since the light-emitting diode lamp 106 with the local address code of 05 has been replaced, no light-emitting diode lamp 106 will emit light, and the current consumption of the light-emitting diode lamp string 104 will be less than or equal to the first A current, so the LED driving device 102 knows that the LED lamp 106 with the local address code of 05 has been removed, and the LED driving device 102 stores and defines (records) the pre- Let the address code 05 be the invalid address code.

In a specific embodiment of the present invention, even if the light emitting diode driving device 102 learns that the light emitting diode lamp 106 with the local address code of 05 has been removed, the light emitting diode driving device 102 is still The predetermined sequence test signals with the predetermined address codes of 06~25 are transmitted to the light-emitting diode lamps 106 of the at least one light-emitting diode lamp string 104 before leaving the predetermined sequence test mode However, the present invention is not limited to this. Once the light-emitting diode driving device 102 learns that the light-emitting diode lamp 106 with the local address code 05 has been removed, the present invention can also leave the preset Sequential test mode (Ie, stop transmitting the predetermined sequence test signals). However, the transmission of the remaining predetermined sequence test signals has an advantage: if another damaged (removed) LED lamp 106 is found, the LED driving device 102 can raise an alarm To notify the user that only one damaged LED lamp 106 can be removed at a time; that is, when the number of failed address codes is greater than or equal to 2, the LED driver device 102 issues a warning signal .

In response to the above-mentioned second problem, the present invention provides an extended sequence test mode to help the light-emitting diode drive device 102 find a new light-emitting diode lamp 106. The content is as follows: After the light emitting diode drive device 102 completes the preset sequence test mode to leave the preset sequence test mode, the light emitting diode drive device 102 enters the extended sequence test mode. When the LED driving device 102 is in the extended sequence test mode: the LED driving device 102 is used to generate a plurality of extended sequence test signals; each of the extended sequence test signals has an extended address code The extension address codes are different; the extension address codes are different from the default address codes; the light emitting diode drive device 102 transmits each of the extension sequence test signals to the at least one light Diode lamp string 104, and correspondingly detect the current consumption of the at least one light-emitting diode lamp string 104; when the current consumption is greater than or equal to a second current (eg, 100mA or 200mA, greater than the first current) At this time, the light emitting diode driving device 102 stores and defines the extended address code corresponding to the extended sequence test signal of the current consumption greater than or equal to the second current as a replacement address code. With this, the light emitting diode driving device 102 knows which light emitting diode lamp 106 is new.

For example, the extension sequence test signals have the extension address codes 26, 27...32, respectively; first, the light emitting diode driving device 102 transmits the extension sequence test signal having the extension address code 26 to the at least The light-emitting diode lamps 106 of a light-emitting diode string 104; at this time, since there is no light-emitting diode lamp 106 with a local address code of 26, no light-emitting diode lamp 106 emits light, Therefore, the current consumption of the at least one light emitting diode lamp string 104 is less than the second current, so that the light emitting diode driving device 102 knows that there is no light emitting diode lamp 106 with the local address code 26.

Then, the light emitting diode driving device 102 transmits the extended sequence test signal with the extended address code 27 to the light emitting diode lamps 106 of the at least one light emitting diode lamp string 104; There is no light-emitting diode lamp 106 with the local address code 27, so no light-emitting diode lamp 106 will emit light, so the current consumption of the at least one light-emitting diode lamp string 104 is less than the second current, by The LED driving device 102 learns that there is no LED lamp 106 with the local address code 27.

And so on, until the light emitting diode driving device 102 transmits the extended sequence test signal with the extended address code of 30 to the light emitting diode lamps 106 of the at least one light emitting diode lamp string 104, because The light-emitting diode lamp 106 with the local address code 30 exists, so the light-emitting diode lamp 106 with the local address code 30 will emit light, and the current consumption of the light-emitting diode string 104 Will be greater than or equal to the second current, so the LED driving device 102 knows that the LED lamp 106 with the local address code 30 has been added to the at least one LED lamp string 104, the The LED driving device 102 stores and defines (records) the extended address code 30 as the replacement address code.

In a specific embodiment of the present invention, the present invention uses a current difference to detect a new LED lamp 106; that is, when none of the LED lamps 106 is lit, a first Current; taking the above embodiment as an example, transmitting the extended sequence test signal with the extended address code of 30 to obtain a second current; and the second current minus the first current is equal to the current difference; if If the current difference is greater than or equal to a specific value (for example, greater than or equal to the above-mentioned second current), the LED driving device 102 learns that the LED lamp 106 with the local address code 30 has been increased To the at least one light emitting diode string 104.

In one embodiment of the present invention, even if the light emitting diode driving device 102 learns that the light emitting diode lamp 106 with the local address code of 30 is new, the light emitting diode driving device 102 still transmits The extended sequence test signals having the extended address codes 31 to 32 respectively to the light-emitting diode lamps 106 of the at least one light-emitting diode lamp string 104 only leave the extended sequence test mode However, the present invention is not limited to this. Once the light-emitting diode driving device 102 learns that the light-emitting diode lamp 106 with the local address code 30 is new, the present invention can leave the extended sequence Test mode (ie, stop transmitting these extended sequence test signals). However, after transmitting the remaining extended sequence test signals, there is an advantage: if another new LED lamp 106 is found, the LED driving device 102 can raise an alarm to notify the user A new light-emitting diode lamp 106 can be added; that is, when the number of replacement address codes is greater than or equal to 2, the light-emitting diode driving device 102 sends out a warning signal. Furthermore, the above extended address codes 31~32 are only examples, and may also be the extended address codes 31~256, etc...

After the light emitting diode drive device 102 completes the extended sequence test mode to leave the extended sequence test mode, the light emitting diode drive device 102 replaces the failed address code with the replacement address code in the test sequence. That is, the light emitting diode driving device 102 replaces the default address code 05 with the extended address code 30 in the test sequence, the test sequence becomes: 01, 02, 03, 04, 30, 06 , 07...25.

Therefore, the next time the light-emitting diode driving device 102 wants to drive the light-emitting diode lamp 106 with the local address code 05 to emit light, the preset address code of the driving light-emitting signal becomes 30 (not 05 ). Finally, in a specific embodiment of the present invention, the light emitting diode driving device 102 can perform a re-confirmation operation: the light emitting diode driving device 102 sequentially transmits the predetermined sequence test signals (the test sequence is: 01 , 02, 03, 04, 30, 06, 07...25) to the light-emitting diode lamps 106 of the at least one light-emitting diode lamp string 104, and correspondingly and sequentially detect the at least one light-emitting diode The current consumption of the body lamp string 104; if the current consumption is greater than the first current each time, the action of replacing the failed address code with the replacement address code is successfully performed.

As another example, the light emitting diode lamp 106 with the local address code 06 is also damaged, and the user replaces the damaged light emitting diode lamp 106 with the new local address code 31 Light emitting diode lamp 106 with the local address code 06; in order to make the light emitting diode driving device 102 It is learned that the light-emitting diode lamp 106 with the local address code 06 is damaged, and the damaged light-emitting diode lamp 106 with the local address code 06 is replaced by the new one with the local address code 31 The light-emitting diode lamp 106 is replaced. The content is similar to the above content: the test button 114 is pressed, so that the LED driving device 102 enters the preset sequence test mode; the preset sequence test signals will have the preset address codes of 01 and 02, respectively , 03, 04, 30, 06...25, the test sequence is 01, 02, 03, 04, 30, 06...25; it should be noted that the original position of 05 has now been replaced by 30.

First, the LED driving device 102 transmits the predetermined sequence test signal with the predetermined address code of 01 to the LED lamps 106 of the at least one LED lamp string 104; , The light-emitting diode lamp 106 with the local address code 01 will emit light to generate the consumption current (greater than the first current), so the light-emitting diode driving device 102 learns that the local address code is 01 The LED lamp 106 is normal. Similarly, the preset sequence test signal with the preset address code 02, 03, 04 is transmitted sequentially; then, the preset sequence test signal with the preset address code 30 Be transmitted.

Then, the LED driving device 102 transmits the predetermined sequence test signal with the predetermined address code of 06 to the LED lamps 106 of the at least one LED lamp string 104, since The light-emitting diode lamp 106 with the original address code 06 has been replaced, so no light-emitting diode lamp 106 will emit light, and the current consumption of the light-emitting diode lamp string 104 will be less than or equal to the first current, Therefore, the light emitting diode driving device 102 knows that the light emitting diode lamp 106 with the local address code 06 has been removed, and the light emitting diode driving device 102 stores and defines (records) the preset address Code 06 becomes the invalid address code.

After the light emitting diode drive device 102 completes the preset sequence test mode to leave the preset sequence test mode, the light emitting diode drive device 102 enters the extended sequence test mode. In the extended order test mode, since the extended address code 30 has been used, the extended order test signals will have the extended address codes 26, 27, 28, 29, 31, 32, respectively.

First, the light emitting diode driving device 102 transmits the extended sequence test signal with the extended address code 26 to the light emitting diode lamps 106 of the at least one light emitting diode lamp string 104; There is no LED lamp 106 with the local address code 26, so no LED lamp 106 will emit light, so the current consumption of the at least one LED lamp string 104 is less than the second current, by The LED driving device 102 knows that there is no LED lamp 106 with the local address code 26. Similarly, the extended sequence test signal with the extended address codes 27, 28, and 29 is transmitted sequentially; then, the extended sequence test signal with the extended address code is 31 is transmitted.

When the light emitting diode driving device 102 transmits the extended sequence test signal with the extended address code 31 to the light emitting diode lamps 106 of the at least one light emitting diode lamp string 104, since they have the local address The light-emitting diode lamp 106 with the code 31 exists, so the light-emitting diode lamp 106 with the local address code 31 will emit light, and the current consumption of the light-emitting diode lamp string 104 will be greater than or equal to the The second current, therefore, the LED driving device 102 knows that the LED lamp 106 with the local address code 31 has been added to the at least one LED lamp string 104, the LED The driving device 102 stores and defines (records) the extended address code 31 as the replacement address code.

After the light emitting diode drive device 102 completes the extended sequence test mode to leave the extended sequence test mode, the light emitting diode drive device 102 replaces the failed address code with the replacement address code in the test sequence. That is, the light emitting diode driving device 102 replaces the default address code 06 with the extended address code 31 in the test sequence, and the test sequence becomes: 01, 02, 03, 04, 30, 31, 07 …25. Therefore, the next time the light emitting diode driving device 102 intends to drive the light emitting diode lamp 106 with the local address code of 06 to emit light, the preset address code of the driving light emitting signal becomes 31 (not 06 ).

Furthermore, each of the predetermined sequence test signals described above further has a test light-emitting signal, and each of the extended sequence test signals described above further has the test light-emitting signal. When the light emitting diode driving device 102 sequentially transmits the predetermined sequence test signals to the light emitting diode lamps 106 of the at least one light emitting diode lamp string 104, if the light emitting diode lamp 106 is The preset address code of the received predetermined sequence test signal is the same as the local address code of the LED lamp 106, then the LED lamp 106 is received according to the LED lamp 106 The test light-emitting signal of the preset sequence test signal is lit to generate the current consumption. When the light-emitting diode driving device 102 transmits each of the extended sequence test signals to the light-emitting diode lamps 106 of the at least one light-emitting diode lamp string 104, if the light-emitting diode lamp 106 is The extended address code of the received extended sequence test signal is the same as the local address code of the light-emitting diode lamp 106, then the light-emitting diode lamp 106 is based on the received light of the light-emitting diode lamp 106 The test light-emitting signal of the extended sequence test signal emits light to generate the current consumption. In order to maximize the current consumption to help the above-mentioned current detection, the test light-emitting signal drives all light-emitting diodes in the light-emitting diode lamp 106 to emit light; for example, if the light-emitting diode lamp 106 includes a Red light-emitting diode (not shown in Figure 1), a green light-emitting diode (not shown in Figure 1) and a blue light-emitting diode (not shown in Figure 1), the red light-emitting diode, The green light emitting diode and the blue light emitting diode are driven together to emit white light.

Furthermore, the AC power supply device 20 transmits an AC power to the AC to DC converter 122; the AC to DC converter 122 receives the AC power and converts the AC power to a first DC power; the AC to DC The converter 122 transmits the first DC power to the DC to DC converter 120; the DC to DC converter 120 converts the first DC power to a second DC power; the DC to DC converter 120 transmits the first Two DC power sources are connected to the light emitting diode driving device 102. The transmitter controller 108 controls the transmitter switch 110 (on or off) to generate the predetermined sequence test signals and the extended sequence test signals; the transmitter memory 112 is used to store the test Sequence, the above-mentioned invalid address code and the above-mentioned alternative address code; the current detector 116 is used To detect the current consumption of the at least one light emitting diode lamp string 104 to notify the sending end controller 108 of the current consumption of the at least one light emitting diode lamp string 104, the current detector 116 may include a resistance element Etc.; the RF receiver 118 is used to receive a wireless remote control signal to control the transmitter controller 108. The third connector 172 is used to connect another LED string 104. A plurality of LED strings 104 in series can be controlled by a single LED driving device 102 in series The number of the LED light strings 104 can be maximized according to demand and local power supply voltage.

Please refer to FIG. 3, which is an external view of the light-emitting diode lamp of the present invention; the light-emitting diode lamp 106 is a light-emitting diode bulb, which is installed in the lamp holder of the light-emitting diode lamp string 104 Inside (not shown in Figure 3).

Please refer back to FIG. 1, the third connector 172 is used to connect the second connector 170 of another LED string 104; when the LED strings 104 are When the second connector 170 is connected in series with the third connectors 172, if a certain light emitting diode lamp 106 of a certain light emitting diode lamp string 104 is replaced by a new light emitting diode lamp 106, the present invention The sequencing method includes the following: First, the transmitter controller 108 knows the consumption of a light emitting diode lamp string 104 when the light emitting diode lamps 106 of the light emitting diode lamp string 104 are not lit. Current (for example, 125mA); therefore, when the sequenced function LED string system 10 is connected to the AC power supply device 20, the LED driving device 102 does not drive any of the LEDs The light string 104 and use the current detector 116 to detect the consumption current to calculate the number of the light emitting diode light strings 104; for example, if the current consumption is 375mA at this time, the light emitting diode light strings The number of 104 is 3 strings (375/125=3).

Next, similar to the above method, but the above current consumption criterion becomes a multiple of the number of the light emitting diode lamp strings 104, for example, 3 times; therefore, for example, when only 2 times of the above current consumption criterion is detected, The LED lamp 106 to be replaced can be found. Finally, the search for a new LED lamp 106 is as described above, so it will not be repeated here.

In other words, in one embodiment of the present invention, the LED string system 10 with sequence function includes N of the LED string strings 104, where N is an integer greater than 1, The N light emitting diode lamp strings 104 are connected in series with each other. When the light emitting diode driving device 102 is in a light string number detection mode: the light emitting diode driving device 102 stops driving the light emitting diode lamps 106 of the N light emitting diode lamp strings 104 to emit light to The current consumption of the N light emitting diode lamp strings 104 is detected, and the number of the N light emitting diode lamp strings 104 is calculated as N accordingly.

When the LED driving device 102 is in the preset sequence test mode: according to the test sequence of the predetermined address codes, the LED driving device 102 sequentially transmits the predetermined sequence test signals to The N light emitting diode lamp strings 104, and correspondingly and sequentially detect the current consumption of the N light emitting diode lamp strings 104; when the current consumption is less than or equal to N times the first current, the The light emitting diode driving device 102 stores and defines the predetermined address code corresponding to the predetermined sequence test signal corresponding to the current consumption less than or equal to N times the first current as the failure address code.

When the light emitting diode driving device 102 is in the extended sequence test mode: the light emitting diode driving device 102 transmits each of the extended sequence test signals to the N light emitting diode lamp strings 104, and correspondingly Respectively detect the current consumption of the N light emitting diode lamp strings 104; when the current consumption is greater than or equal to the second current, the light emitting diode driving device 102 stores and defines that the current consumption is greater than or equal to the first The extended address code of the extended sequence test signal of the two currents becomes the replacement address code. The rest of the content is the same as mentioned above, so it will not be repeated here.

Please refer to FIG. 5, which is a block diagram (series connection) of another embodiment of the light emitting diode lamp string system with sequencing function according to the present invention; please refer to FIG. 8, which has sequencing function according to the present invention A block diagram (in series) of another embodiment of a light emitting diode lamp string system. In FIG. 5 and FIG. 8, the light-emitting diode lamps 106 are connected in series with each other, and the remaining contents of FIG. 5 and FIG. 8 are the same as described above, so they will not be repeated here.

Please refer to FIG. 6, which is a circuit block diagram (series connection) of the light-emitting diode lamp of the present invention; the light-emitting diode lamp 106 shown in FIG. 6 is applied to FIGS. 5 and 8. Each of the light-emitting diode lamps 106 includes a voltage stabilizer 174, an oscillator 176, a signal conversion unit 178, an address and data identification Identifier 180, a logic controller 182, a shift register 184, an output register 186, a light-emitting diode drive circuit 188, a bit address register 190, a bit address comparator 192, a bit Address memory 194, a first light-emitting diode 156, a second light-emitting diode 158, and a third light-emitting diode 160; the above-mentioned elements are electrically connected to each other.

Please refer to FIG. 7, which is a voltage-current curve diagram of the voltage regulator of the present invention; please also refer to FIGS. 5, 6, and 8; the voltage regulator 174 may be, for example, an inductive diode. If the voltage regulator 174 is operating normally, the light-emitting diode lamp 106 operates to emit light from the first light-emitting diode 156, the second light-emitting diode 158, and the third light-emitting diode 160 or No light (current consumption or current consumption); the voltage change caused by such a current change is not large, so the current detector 116 will not be able to effectively detect current consumption; for example, in FIG. 7 Near the voltage VN, the voltage change corresponding to the first current interval R1 is not large.

In order to increase the voltage change, the voltage regulator 174 must stop operating; if the voltage regulator 174 stops operating, when the light-emitting diode lamp 106 is turned on or off, the current change will cause a large voltage change , So that the current detector 116 can effectively detect the current consumption to notify the transmitter controller 108; for example, before the voltage VL in FIG. 7, the voltage change corresponding to the second current interval R2 is larger Where the first current interval R1 is equal to the second current interval R2; obviously, the voltage change corresponding to the second current interval R2 is greater than the voltage change corresponding to the first current interval R1.

There are two ways to stop the operation of the regulator 174: one way is to reduce a driving voltage of the regulator 174, so that the regulator 174 stops operation; another way is that the light emitting diode driving device 102 transmits A command signal is sent to the logic controller 182, so that the logic controller 182 turns off the regulator 174.

In more detail, compared to the parallel mode, the series mode adds the regulator 174; the main purpose is to maintain each of the light emitting diode lamps 106 on the series path at a close voltage; because each The colors of the light-emitting diode lamps 106 are not necessarily the same, so the equivalent impedance is different. The voltage regulator 174 is adjusting this problem; this function will conflict with the aforementioned method of using the current difference to determine which position is not lit and the new address code of the lamp; therefore, when entering the detection mode, there are two The method can stop the regulator 174 from operating:

1. Before performing the preset sequence test mode and the extended sequence test mode, reduce the driving voltage of the voltage regulator 174 so that each of the light-emitting diode lamps 106 works when the voltage regulator 174 is not turned on Voltage VL; that is, the regulator 174 is disabled.

2. Before performing the predetermined sequence test mode and the extended sequence test mode, the LED driving device 102 transmits the command signal to the logic controller 182, so that the logic controller 182 turns off the regulator 174.

Furthermore, the other contents of the series type are the same as the contents of the above-mentioned parallel type. In addition, since the serial type does not have the problem that the parallel type needs to reduce the high DC voltage to supply power to the electronic parts, the integrated lamp beads can be used, and the series type circuit is relatively simple.

Please refer to FIG. 4, which is a flowchart of the sequencing method of the present invention. A sequencing method of the present invention includes the following steps:

Step S02: A light-emitting diode driving device executes a predetermined sequential test mode to detect a failed address code. Next, the sequencing method proceeds to step 04.

Step S04: The light emitting diode driving device executes an extended sequence test mode to detect an alternative address code. Next, the sequencing method proceeds to step 06.

Step S06: The LED driving device replaces the invalid address code with the replacement address code in a test sequence.

Wherein, the light emitting diode driving device executes the preset sequence test mode includes the following contents: the light emitting diode driving device generates a plurality of preset sequence test signals, wherein each of the preset sequence test signals has a preset Address codes, the preset address codes are different; according to the test sequence of the preset address codes, the light emitting diode drive device sequentially transmits the preset sequence test signals To a light emitting diode lamp string to detect the current consumption of one of the light emitting diode lamp strings, wherein in the test sequence, the predetermined address codes are arranged in order according to size, wherein the light emitting diode The light string includes a plurality of light-emitting diode lamps that are electrically connected to each other (ie, may be connected in parallel or in series); if the consumption current is less than or equal to a first current, the light-emitting diode The polar body driving device records the predetermined address code corresponding to the predetermined sequence test signal of the current consumption less than or equal to the first current as the failure address code.

Wherein, the light emitting diode driving device executes the extended sequence test mode includes the following content: the light emitting diode driving device generates a plurality of extended sequence test signals, wherein each of the extended sequence test signals has an extended address code, The extended address codes are different, and the extended address codes are different from the predetermined address codes; the light emitting diode driving device transmits each of the extended sequence test signals to the light emitting diode lamp, respectively String to detect the current consumption of the LED string; if the current consumption is greater than or equal to a second current, the LED drive device records the extension corresponding to the current consumption greater than or equal to the second current The extended address code of the sequential test signal becomes the replacement address code.

Each of the light emitting diode lamps has a local address code; the local address codes are different; each of the predetermined sequence test signals further has a test light signal; each of the extended sequence test signals It also has the test luminescence signal. When the light emitting diode driving device sequentially transmits the preset sequence test signals to the light emitting diode lamps of the light emitting diode lamp string, if the light emitting diode lamp receives the preset The predetermined address code of the sequential test signal is the same as the local address code of the light emitting diode lamp, then the light emitting diode lamp is based on the predetermined sequence test signal received by the light emitting diode lamp The test light-emitting signal emits light to generate the current consumption. When the light emitting diode driving device transmits each of the extended sequence test signals to the light emitting diode lamps of the light emitting diode lamp string, if the extended order received by the light emitting diode lamp is The extended address code of the test signal Same as the local address code of the light emitting diode lamp, the light emitting diode lamp emits light according to the test light emitting signal of the extended sequence test signal received by the light emitting diode lamp to generate the consumption current.

The remaining content of the sequencing method of the present invention is similar to the foregoing content, and is a brevity factor, so it will not be repeated here.

The effect of the present invention is to enable the new light-emitting diode lamp to replace the damaged light-emitting diode lamp to correctly emit light according to the content of the driving light-emitting signal.
