Accompanying drawing explanation
Fig. 1 is the circuit diagram of light-operated LED road lamp.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of light-operated LED road lamp, comprises resistance R1, diode VD1, light-emitting diode VD2, phototriode VT1, electric capacity C1 and one-way SCR VS, resistance R1 one end connects power supply VCC respectively, resistance R9 and light-emitting diode VD2 positive pole, the resistance R1 other end connects diode VD1 negative pole respectively, electric capacity C1, resistance R2, resistance R4, resistance R5 and resistance R6, the resistance R2 other end connects phototriode VT1 collector electrode respectively, electric capacity C2 and resistance R3, resistance R3 other end connecting triode VT2 base stage, the triode VT2 collector electrode contact resistance R4 other end, triode VT3 collector electrode is the contact resistance R5 other end and triode VT4 base stage respectively, and triode VT3 emitter is contact resistance R10 respectively, the resistance R9 other end and triode VT4 emitter, triode VT4 collector electrode is the contact resistance R6 other end and resistance R7 respectively, the G pole of resistance R7 other end difference contact resistance R8 and one-way SCR VS, the A pole connecting luminous diode VD2 negative pole of one-way SCR VS, the K pole of one-way SCR VS connects diode VD1 positive pole respectively, the electric capacity C1 other end, phototriode VT1 emitter, the electric capacity C2 other end, the resistance R10 other end and the resistance R8 other end.
