The accompanying drawing explanation
Fig. 1 is the power-switching circuit in the LED lamp.
The specific embodiment
In order to be illustrated more clearly in the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is described in more detail.
Referring to Fig. 1, a kind of LED lamp of non-transformer supply, comprise 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 to become direct current by the electric current of LED 1, LED2; In addition, by giving LED 1, LED2 series connection current regulator diode D1, the effectively fluctuation of control circuit electric current, the problem of releasing LED 1, LED2 light flash, reduce the damage of circuit elements device and lamp grain to a certain extent; Coordinate with rectifier bridge BR1's by resistance R 1, R2, the immediate current of thunderbolt can be weakened, playback, reach good anti-lightning strike effect.
