Problems solved by technology
[0002] At present, LED is eliminating incandescent street lamps due to its high power saving rate. However, the current LED street lamps have a single function, lack of timing automatic dimming function, and lack of heat dissipation function of semiconductor cooling fins, so that the energy saving rate of LED street lamps has not been achieved. Sufficiently improved, the service life of the lamp is not long

Embodiment Construction
[0006] As shown in the figure, D1, D2, R1, R2, R3, and C1 form an electronic transformer circuit. R1 is an adjustable resistor. By adjusting the value of R1, the input AC 220V voltage becomes the required AC output voltage value for the following The voltage required by the first-stage circuit; B is a single-phase full-wave rectifier circuit, which converts the AC voltage output by the electronic transformer into a pulsating DC voltage to supply the working voltage of the next-stage circuit.
[0007] As shown in the figure, D4, R4, R5, R6, C2, and C3 form a thyristor phase-shift control circuit, which controls the DC voltage in the range of about 40V to supply the working voltage of the LED street lamp.
[0008] As shown in the attached figure, IC1, R7, C5 and IC2, R8, C6 are two sets of independent constant current power supply circuits. By selecting the appropriate value of R7 or R8, the required constant current power supply value can be obtained, and the two A group of con...
