Description of drawings
Fig. 1 is the power-switching circuit in the LED lamp.
The specific embodiment
In order to be illustrated more clearly in technical scheme of the present invention, below in conjunction with accompanying drawing, the present invention will be further described in detail.
Referring to Fig. 1, a kind of LED lamp of non-transformer supply comprises at least one power-switching circuit unit, and described power-switching circuit unit comprises: resistance R 1, R2, rectifier bridge BR1, current regulator diode D1, LED 1, LED2; The end of R1, the end of R2 are connected with two outputs of civil power respectively, the other end of R1, the other end of R2 are connected with two interchange ends of rectifier bridge BR1 respectively, the direct-flow positive pole end of rectifier bridge BR1 is connected with the positive pole of current regulator diode D1, the negative pole of current regulator diode D1 is connected with the positive pole of LED 1, the negative pole of LED 1 is connected with the positive pole of LED 2, and the negative pole of LED 2 is connected with the direct current negative pole of rectifier bridge BR1.
This power-switching circuit unit has substituted the power supply unit in traditional LED lamp, and its effect is the high-voltage alternating civil power to be converted to the needed low-voltage DC of light source of LED lamp.Input high-voltage alternating civil power by the dividing potential drop of resistance R 1, R2, can make the voltage at LED 1 two ends, LED 2 two ends become low pressure; By the rectification of rectifier bridge BR1, can make the electric current by LED 1, LED2 become direct current; In addition, by the current regulator diode D1 that connects to LED 1, LED2, the effectively fluctuation of control circuit electric current, the problem of releasing LED 1, LED2 light flash reduces the damage of circuit elements device and lamp grain to a certain extent; Coordinate with rectifier bridge BR1's by resistance R 1, R2, can with the thunderbolt immediate current weaken, playback, reach good anti-lightning strike effect.
Particularly, when the high-voltage alternating civil power was 220V, each component parameters of power-switching circuit was: resistance R 1 is 1k Ω for 1k Ω, R2, and rectifier bridge BR1 is the HD06-T-F model, current regulator diode D1 is the S-183T model, and LED 1 is that 3020 models, LED2 are 3020 models.When the high-voltage alternating civil power is 110V, each component parameters of power-switching circuit is: resistance R 1 is that 300 Ω, R2 are 300 Ω, rectifier bridge BR1 is the HD06-T-F model, and current regulator diode D1 is the S-183T model, and LED 1 is that 3020 models, LED2 are 3020 models.
Because the power of single led light emitting diode is lower, a little less than causing the illumination extremely of single led LED source, so in order to obtain the stronger illumination of larger power, a plurality of LEDs need to be used together.So array that the LED lamp is comprised of power-switching circuit described above unit.In one embodiment, the array scale of one LED lamp is 12 ﹡ 28, namely this LED lamp laterally has 12 described power-switching circuit unit, 28 described power-switching circuit unit are vertically arranged, each power-switching circuit has 2 light emitting diodes in the unit, i.e. 2 LED light sources are so this LED lamp has 28 LED light sources of 2 ﹡ 12 ﹡.In reality, can according to actual needs, select the LED lamp of different array scales.
In addition, the power-switching circuit unit is arranged on the PCB circuit board, punches one by one in the place of PCB circuit board respective leds, and the back side of PCB circuit board scribbles thermal grease, the LED lamp of this non-transformer supply also comprises aluminium base shell, and the PCB circuit board is arranged on aluminium base enclosure.
When lumination of light emitting diode, the hole that the heat that its lamp pearl produces can pass through to be beaten in time distributes rapidly, and the back side of PCB circuit board scribbles thermal grease in addition, can further assist the PCB heat dissipation for circuit board, and the dissipation of heat of PCB circuit board is gone out.
The PCB circuit board is arranged on aluminium base enclosure again, the heat that LED lamp bead punches and comes out by institute, the heat that the PCB circuit board comes out by thermal grease, all will be by the transfer of air in shell to shell, this shell is aluminium base shell, utilize the thermal conductive resin of metal, can further reach the purpose with the abundant heat-shift in the external world, play thermolysis preferably.
Above content is only embodiments of the invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and the content of this specification should not be construed limitation of the present invention
