According to an example, the light source 110 may be implemented as an LED light source. For example, when the light source 110 is implemented as an LED light source, the light source 110 may include a plurality of LEDs and a plurality of printed circuit boards made of a high thermal conductive material to support the LEDs.

The converter 120 receives an AC power and converts the DC power into a DC voltage to supply a constant DC voltage to the light source 110. Here, when the light source 110 includes a plurality of LEDs, the converter 120 may stably supply a constant DC voltage to each of the plurality of LEDs. According to an example, the converter 120 may receive a pulse width modulated signal from the control module 150, and the dimming level of the DC voltage provided to the light source 110 may be controlled by the pulse width modulated signal. In addition, the converter 120 may be disposed to be spaced apart from the path of the light emitted from the light source 110 to prevent heat generation of the converter 120.

The first sensor module 130 may be disposed inside the housing 160 to detect a temperature or illuminance of the light source 110. In detail, the first sensor module 130 may be disposed close to the light source 110 in the housing 160. For example, the first sensor module 130 may be disposed in a path of light emitted from the light source 110 to detect a temperature or illuminance of the light source 110. The first sensor module 130 may detect the temperature or illuminance of the light source 110 and provide the temperature or illuminance value of the light source 110 to the control module 150.

The first sensor module 130 may include a first temperature sensor 131 and a first illuminance sensor 132. The first temperature sensor 131 may be disposed in a path of light emitted from the light source 110 to detect the temperature of the light source 110 and provide the temperature value of the light source 110 to the control module 150. In addition, the first illuminance sensor 132 may be disposed in a path of light emitted from the light source 110 to detect the illuminance of the light source 110 and provide the illuminance value of the light source 110 to the control module 150. .

The second sensor module 140 may be disposed outside the housing 160 to detect a temperature or illuminance of the outside of the lighting device 100. In detail, the second sensor module 140 may be spaced apart from the lighting device 100 to detect a temperature or illuminance of a space in which the lighting device 100 is disposed. The second sensor module 140 may detect a temperature or illuminance of the outside of the lighting device 100 and provide an external temperature or illuminance value to the control module 150 through wireless or wired communication.

The second sensor module 140 may include a second temperature sensor 141 and a second illuminance sensor 142. The second temperature sensor 141 may be disposed to be spaced apart from the lighting device 100 to detect the temperature of the space where the lighting device 100 is disposed, and provide an external temperature value to the control module 150. In addition, the second illuminance sensor 142 may be disposed to be spaced apart from the lighting apparatus 100 to detect an illuminance of the space in which the lighting apparatus 100 is disposed, and provide an external illuminance value to the control module 150. .

According to an example, the second sensor module 140 may be arranged to be spaced apart from the bottom of the space where the lighting device 100 is disposed. For example, the second sensor module 140 may be disposed 1m apart from the bottom of the space where the lighting device 100 is disposed. Accordingly, the second sensor module 140 may accurately measure the temperature or illuminance of the space where the lighting device 100 is disposed, without being affected by the floor temperature of the space where the lighting device 100 is disposed.

The control module 150 receives a temperature value or illuminance value of the light source 110 from the first sensor module 130, or receives an external temperature value or illuminance value from the second sensor module 140 to generate the light source 110. The illuminance of can be controlled. In detail, the control module 150 determines the failure of the lighting apparatus 100 based on at least one of the temperature value and illuminance value of the light source and the temperature value and illuminance value of the outside of the lighting apparatus 100, or the light source 110. It is possible to extend the life of the lighting device 100 by controlling the illuminance. According to an example, the control module 150 may be disposed to be spaced apart from the path of the light emitted from the light source 110 to prevent heat generation of the control module 150.

The control module 150 may generate an alarm when the failure of the lighting apparatus 100 is determined, and may turn off the light source 110. When the failure of the lighting apparatus 100 is determined, the control module 150 may provide the corresponding information to the control unit 200. In addition, the control unit 200 may receive information on the failure of the lighting device 100 from the control module 150, and may generate an alarm separate from the lighting device 100.

The control module 150 may control the illuminance of the light source 110 when the temperature of the light source 110 is higher than the reference value or the temperature of the space in which the lighting device 100 is disposed is higher than the reference value. For example, the control module 150 reduces the illuminance of the light source 110 when the temperature of the light source 110 is higher than the reference value, or when the temperature of the space where the lighting device 100 is disposed is higher than the reference value. The temperature of the light source 110 and the temperature of the space in which the lighting device 100 is disposed may be reduced. As such, the control module 150 according to the present invention can prolong the life of the lighting apparatus 100 by suppressing the increase in the junction temperature and the room temperature of the light source 110.

According to an example, the control module 150 may include a central processing unit 151, a wireless communication unit 152, and a pulse width modulator 153.

The control module 150 may have an illuminance table corresponding to the first sensor module 130 according to the lighting control step, and the illuminance value of the illuminance table corresponding to the control step and the illuminance value generated by the first sensor module 130. If the difference is out of a certain range, a failure alarm may be generated. Therefore, the control module 150 may control the illuminance of the light source 110 step by step based on the illuminance table, and may generate a failure alarm when the illuminance of the light source 110 is out of the range defined in the illuminance table. .

The central processor 151 may store preset first to sixth reference values. In detail, the central processing unit 151 may store the first to sixth reference values provided from the control unit 200. Here, each of the first to sixth reference values may correspond to one of a temperature value and illuminance value of the light source and a temperature value and illuminance value of the outside of the lighting apparatus 100. That is, the central processing unit 151 compares at least one of the temperature value and illuminance value of the light source and the temperature value and illuminance value of the outside of the lighting apparatus 100 with at least one of the first to sixth reference values corresponding thereto. The life of the lighting device 100 may be extended by determining whether the 100 is normally operated or controlling the illuminance of the light source 110.

The wireless communication unit 152 may perform wireless communication. According to an example, the wireless communication unit 152 may receive a temperature value and an illuminance value of the outside of the lighting device 100 from the second sensor module 140 through wireless communication. In addition, the wireless communication unit 152 may transmit the current state and normal operation of the lighting device 100 to the control unit 200 or receive a control signal from the control unit 200 through wireless communication.

According to another example, when the lighting device 100 is connected to the second sensor module 140 and the control unit 200 by wired communication, the wireless communication unit 152 may be omitted.

The pulse width modulator 153 may change the pulse width of the power supplied to the light source 110. Specifically, the pulse width modulator 153 compares one of the temperature value and illuminance value of the light source with the temperature value and illuminance value of the outside of the lighting apparatus 100 with at least one of the first to sixth reference values corresponding thereto. The pulse width of the power supply can be changed based on the comparison result. For example, the pulse width modulator 153 may be configured according to a comparison result of at least one of a temperature value and an illuminance value of the light source, a temperature value and illuminance value of the outside of the lighting apparatus 100, and first to sixth reference values. The pulse width modulated signal may be provided to the converter 120, and the converter 120 may control the dimming level of the DC voltage provided to the light source 110 based on the pulse width modulated signal.

According to an example, the control module 150 receives the temperature value of the light source 110 from the first sensor module 130, and generates an alarm when the temperature value of the light source 110 is equal to or greater than the first reference value. 110 may be turned off. Here, the first reference value is a criterion for determining abnormal overheating of the lighting apparatus 100. When the temperature value of the light source 110 is equal to or greater than the first reference value, a malfunction of the lighting apparatus 100 occurs or the lighting apparatus 100 may be broken. In addition, the first reference value may be changed according to specifications of the light source 110. Therefore, when the temperature value of the light source 110 is greater than or equal to the first reference value, the control module 150 generates an alarm and induces replacement or repair of the lighting device 100 by turning off the light source 110. have.

According to an example, the control module 150 receives the illuminance value of the light source 110 in the turn-on state of the light source 110, and if the illuminance value of the light source 110 is less than or equal to the second reference value, the light source 110. ) Can increase the illuminance or generate an alarm. Here, the second reference value is a criterion for determining whether the light source 110 is normally operated when the light source 110 is turned on. When the illuminance value of the light source 110 is less than or equal to the second reference value, the light source ( The illuminance of 110 may be lower than during normal operation. Therefore, when the illuminance value of the light source 110 is less than or equal to the second reference value when the light source 110 is turned on, the control module 150 may increase the illuminance of the light source 110 or generate an alarm.

According to an example, the control module 150 receives the illuminance value of the light source 110 in the turn-off state of the light source 110, and generates an alarm when the illuminance value of the light source 110 is greater than or equal to the third reference value. You can. Here, the third reference value is a criterion for determining whether the operation of the light source 110 is stopped while the light source 110 is turned off, and the third reference value of the light source 110 is turned off in the turn-off state of the light source 110. If the illuminance value is less than or equal to the third reference value, the operation of the light source 110 may not be properly stopped. Therefore, the control module 150 generates an alarm when the illuminance value of the light source 110 is greater than or equal to the third reference value when the light source 110 is turned off, so that the operation of the light source 110 is not properly stopped. Can be informed.

According to an example, the control module 150 receives the temperature value of the light source 110 from the first sensor module 130, and if the temperature value of the light source 110 is greater than or equal to the fourth reference value and less than the first reference value, The illuminance of the light source 110 may be reduced. Here, the first reference value corresponds to a criterion for determining abnormal overheating of the lighting apparatus 100, and the fourth reference value corresponds to a criterion for determining whether the junction temperature of the light source 110 rises. . For example, the first reference value with respect to the temperature of the light source 110 may be higher than the fourth reference value. That is, when the temperature value of the light source 110 is greater than or equal to the fourth reference value and less than the first reference value, the lighting apparatus 100 may not correspond to a malfunction state, but may correspond to a state where the junction temperature of the light source 110 is increased. Can be. Therefore, when the temperature value of the light source 110 is greater than or equal to the fourth reference value and less than the first reference value, the control module 150 reduces illumination of the light source 110, thereby lowering the junction temperature of the light source 110 to illuminate the light. The life of the device 100 can be extended.

According to an example, the control module 150 receives a temperature value of the light source 110 from the first sensor module 130 and receives an illuminance value outside the lighting device 100 from the second sensor module 140. When the temperature value of the light source 110 is greater than or equal to the fourth reference value and is less than the first reference value, and the illuminance value outside the lighting device 100 exceeds the fifth reference value, the illuminance of the light source 110 may be reduced. have. Here, the first reference value corresponds to a criterion for determining abnormal overheating of the lighting apparatus 100, and the fourth reference value corresponds to a criterion for determining whether the junction temperature of the light source 110 rises. The fifth reference value corresponds to a standard of minimum illuminance required for a space in which the lighting device 100 is disposed. For example, the minimum illuminance required for the space in which the lighting apparatus 100 is disposed may correspond to the minimum illuminance required for the work performed in the space in which the lighting apparatus 100 is disposed, but is not necessarily limited thereto. That is, even when the lighting device 100 does not correspond to a malfunction state but corresponds to a state where the junction temperature of the light source 110 is increased, even when the control module 150 reduces the illuminance of the light source 110, the control module ( 150 may maintain the minimum illuminance required for the space in which the lighting device 100 is disposed. Therefore, when the temperature value of the light source 110 is greater than or equal to the fourth reference value and is less than the first reference value, and the illuminance value outside the lighting device 100 exceeds the fifth reference value, By reducing the illuminance of the light source 110 within a range that maintains the minimum illuminance of the space in which 100 is disposed, the junction temperature of the light source 110 can be lowered to extend the life of the lighting device 100.

According to an example, the control module 150 receives a temperature value outside the lighting device 100 from the second sensor module 140, and if the temperature value outside the lighting device 100 is greater than or equal to the sixth reference value, the light source. The roughness of 110 may be reduced. Here, the sixth reference value corresponds to a criterion for determining whether the room temperature of the space where the lighting device 100 is disposed increases. If the temperature value outside the lighting device 100 is greater than or equal to the sixth reference value, the life of the lighting device 100 may be shortened. Therefore, when the temperature value outside the lighting device 100 is equal to or greater than the sixth reference value, the control module 150 reduces the illuminance of the light source 110 to lower the room temperature of the space in which the lighting device 100 is disposed to illuminate the lighting. The life of the device 100 can be extended.

According to an example, the control module 150 receives a temperature value and an illuminance value of the outside of the lighting device 100 from the second sensor module 140, such that the temperature value of the outside of the lighting device 100 is greater than or equal to the sixth reference value. When the illuminance value outside the illumination device 100 exceeds the fifth reference value, the illuminance of the light source 110 may be reduced. Here, the sixth reference value corresponds to a criterion for determining whether the room temperature of the space where the lighting device 100 is disposed increases or not, and the fifth reference value is the minimum required for the space where the lighting device 100 is disposed. Corresponds to the standard of illuminance. For example, the minimum illuminance required for the space in which the lighting apparatus 100 is disposed may correspond to the minimum illuminance required for the work performed in the space in which the lighting apparatus 100 is disposed, but is not necessarily limited thereto. That is, when the lighting device 100 does not correspond to a malfunction state but the room temperature of the space in which the lighting device 100 is disposed is increased, the control module 150 reduces the illuminance of the light source 110. In addition, the control module 150 may maintain the minimum illuminance required for the space in which the lighting device 100 is disposed. Therefore, when the temperature value outside the lighting device 100 is greater than or equal to the sixth reference value and the illuminance value outside the lighting device 100 exceeds the fifth reference value, the control device 150 is disposed. By reducing the illuminance of the light source 110 within the range of maintaining the minimum illuminance of the space, the room temperature of the space in which the illuminating device 100 is disposed may be lowered to extend the life of the illuminating device 100.

The housing 160 may accommodate the light source 110, the converter 120, the first sensor module 130, and the control module 150. That is, the housing 160 configures the exterior of the lighting device 100 and protects the components inside the lighting device 100.

The control unit 200 is connected to the at least one lighting device 100 in a wired or wireless communication manner, so that at least one of a temperature value and illuminance value of the light source 110 and a temperature value and illuminance value outside the lighting device 100. An alarm may be generated or the state of the at least one lighting device 100 may be monitored based on the result.

The control unit 200 may include an information collection module 210 and a central processing module 220. The information collection module 210 is connected to the at least one lighting device 100 in a wired or wireless communication manner so that at least one of a temperature value and an illuminance value of the light source 110 and a temperature value and illuminance value outside the lighting device 100 is provided. One may be received and provided to the central processing module 220. In addition, the information collection module 210 may provide the illumination control signal provided from the central processing module 220 to the at least one lighting device 100. The at least one lighting device 100 may increase, decrease or maintain the illumination of the light source 110 by receiving an illumination control signal from the control unit 200.

The central processing module 220 generates an alarm based on at least one of the temperature value and the illuminance value of the light source 110 and the temperature value and the illuminance value outside the lighting device 100, or at least one lighting device 100. You can monitor the status of Specifically, the central processing module 220 may receive at least one of a temperature value and an illuminance value of the light source 110 and a temperature value and illuminance value of the outside of the lighting device 100, and additionally, Whether to turn on, and other state information of the lighting device 100 can be received. Therefore, the central processing module 220 may monitor the state of the lighting device 100 to manage driving of the lighting device 100 or to generate an alarm.

The central processing module 220 may set first to sixth reference values corresponding to the at least one lighting device 100 and provide the same to the at least one lighting device 100. According to an example, the central processing module 220 may be connected to each of the plurality of lighting devices 100, and each of the plurality of lighting devices 100 may include specifications of the lighting device 100 and the lighting device 100. Space may vary. Accordingly, the central processing module 220 may set the first to sixth reference values corresponding to each of the plurality of lighting devices 100 and provide the first to sixth reference values to each of the plurality of lighting devices 100. The state of each of the plurality of lighting devices 100 may be monitored based on the six reference values. As a result, the central processing module 220 controls the illuminance of the light source 110 of each of the plurality of lighting devices 100, or an alarm for the lighting device 100 that needs to be replaced or repaired among the plurality of lighting devices 100. Can be generated.

3 is a flowchart illustrating a process of controlling illuminance of a light source based on a temperature value of the light source or an external illuminance value.

Referring to FIG. 3, the control module 150 receives a temperature value of the light source 110 from the first sensor module 130 and receives an illuminance value outside the lighting device 100 from the second sensor module 140. (Step S310), the temperature value of the light source 110 may be compared with the first and fourth reference values (steps S320 and S330), and the illuminance value of the outside of the lighting apparatus 100 may be compared with the fifth reference value ( Step S340).

If the temperature value of the light source 110 is greater than or equal to the fourth reference value and is less than the first reference value, and the illuminance value outside the lighting device 100 exceeds the fifth reference value, the control module 150 of the light source 110 Roughness can be reduced (step S350). Here, the first reference value corresponds to a criterion for determining abnormal overheating of the lighting apparatus 100, and the fourth reference value corresponds to a criterion for determining whether the junction temperature of the light source 110 rises. The fifth reference value corresponds to a standard of minimum illuminance required for a space in which the lighting device 100 is disposed. For example, the minimum illuminance required for the space in which the lighting apparatus 100 is disposed may correspond to the minimum illuminance required for the work performed in the space in which the lighting apparatus 100 is disposed, but is not necessarily limited thereto.

Meanwhile, if the temperature value of the light source 110 is equal to or greater than the first reference value, the control module 150 may determine a failure of the lighting device 100 to generate an alarm and turn off the light source 110 (step) S360).

In addition, the control module 150 may maintain the illuminance of the light source 110 when the illuminance value of the outside of the lighting apparatus 100 reaches the fifth reference value in the process of decreasing the illuminance of the light source 110 step by step. (Step S370). That is, even when the lighting device 100 does not correspond to a malfunction state but corresponds to a state where the junction temperature of the light source 110 is increased, even when the control module 150 reduces the illuminance of the light source 110, the control module ( 150 may maintain the minimum illuminance required for the space in which the lighting device 100 is disposed.

Therefore, when the temperature value of the light source 110 is greater than or equal to the fourth reference value and is less than the first reference value, and the illuminance value outside the lighting device 100 exceeds the fifth reference value, By reducing the illuminance of the light source 110 within a range that maintains the minimum illuminance of the space in which 100 is disposed, the junction temperature of the light source 110 can be lowered to extend the life of the lighting device 100.

4 is a flowchart illustrating a process of controlling the illuminance of the light source based on the illuminance value of the light source in the turn-on state of the light source.

Referring to FIG. 4, the control module 150 receives the illuminance value of the light source 110 in the turn-on state of the light source 110 (step S410) (step S420), and adjusts the illuminance value of the light source 110. Two reference values can be compared (step S430).

If the illuminance value of the light source 110 is less than or equal to the second reference value, the control module 150 may increase the illuminance of the light source 110 or generate an alarm (step S440). Here, the second reference value is a criterion for determining whether the light source 110 is normally operated when the light source 110 is turned on. When the illuminance value of the light source 110 is less than or equal to the second reference value, the light source ( The illuminance of 110 may be lower than during normal operation. Therefore, when the illuminance value of the light source 110 is less than or equal to the second reference value when the light source 110 is turned on, the control module 150 may increase the illuminance of the light source 110 or generate an alarm.

5 is a flowchart illustrating a process of determining whether a lighting device is defective based on an illuminance value of a light source in a turn-off state of the light source.

Referring to FIG. 5, the control module 150 receives the illuminance value of the light source 110 in the turn-off state of the light source 110 (step S510) (step S520), and adjusts the illuminance value of the light source 110. Three reference values can be compared (step S530).

If the illuminance value of the light source 110 is equal to or greater than the third reference value, the control module 150 may generate an alarm (step S540). Here, the third reference value is a criterion for determining whether the operation of the light source 110 is stopped while the light source 110 is turned off, and the third reference value of the light source 110 is turned off in the turn-off state of the light source 110. If the illuminance value is less than or equal to the third reference value, the operation of the light source 110 may not be properly stopped. Therefore, the control module 150 generates an alarm when the illuminance value of the light source 110 is greater than or equal to the third reference value when the light source 110 is turned off, so that the operation of the light source 110 is not properly stopped. Can be informed.

6 is a flowchart illustrating a process of controlling illuminance of a light source based on an external temperature value or an external illuminance value.

Referring to FIG. 6, the control module 150 receives a temperature value and an illuminance value of the outside of the lighting apparatus 100 from the second sensor module 140 (step S610), thereby adjusting the temperature value of the outside of the lighting apparatus 100. It may be compared with the sixth reference value (step S620), and the illuminance value outside the lighting apparatus 100 may be compared with the fifth reference value (step S630).

If the temperature value outside the illumination device 100 is greater than or equal to the sixth reference value and the illumination value outside the illumination device 100 exceeds the fifth reference value, the control module 150 may reduce the illumination of the light source 110. (Step S640). Here, the sixth reference value corresponds to a criterion for determining whether the room temperature of the space where the lighting device 100 is disposed increases or not, and the fifth reference value is the minimum required for the space where the lighting device 100 is disposed. Corresponds to the standard of illuminance. For example, the minimum illuminance required for the space in which the lighting apparatus 100 is disposed may correspond to the minimum illuminance required for the work performed in the space in which the lighting apparatus 100 is disposed, but is not necessarily limited thereto.

In addition, the control module 150 may maintain the illuminance of the light source 110 when the illuminance value of the outside of the lighting apparatus 100 reaches the fifth reference value in the process of decreasing the illuminance of the light source 110 step by step. (Step S650). That is, when the lighting device 100 does not correspond to a malfunction state but the room temperature of the space in which the lighting device 100 is disposed is increased, the control module 150 reduces the illuminance of the light source 110. In addition, the control module 150 may maintain the minimum illuminance required for the space in which the lighting device 100 is disposed. Therefore, when the temperature value outside the lighting device 100 is greater than or equal to the sixth reference value and the illuminance value outside the lighting device 100 exceeds the fifth reference value, the control device 150 is disposed. By reducing the illuminance of the light source 110 within the range of maintaining the minimum illuminance of the space, the room temperature of the space in which the illuminating device 100 is disposed may be lowered to extend the life of the illuminating device 100.

As such, the lighting control system 10 is connected to the at least one lighting device 100 in a wired or wireless communication manner, based on at least one of a temperature value and an illuminance value of the light source and an external temperature value and illuminance value of the light source.
