Description
Technical field
The utility model relates to a kind of LED, specifically a kind of light-operated LED.
Background technology
Along with the development of society, light control techniques is quite ripe, the concept of Light control road lamp has put forward a lot of year, but existing street lamp is most or time-controlled, study carefully the reason that it can not be promoted the use of, mostly be that stability is low and cost is too high, how improve the stability of Light control road lamp and reduce the research direction that cost becomes a lot of manufacturer.
Utility model content
The purpose of this utility model is the light-operated LED providing a kind of low cost, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of light-operated LED, comprises photo resistance RG, diode D1, diode D2, triode VT1, IGBT manages, electric capacity C1 and diode D3, described photo resistance RG one end connecting triode VT1 base stage, triode VT1 emitter connects ground capacity C3 respectively, triode VT2 emitter and triode VT4 emitter, triode VT1 collector electrode is contact resistance R3 and resistance R2, resistance R2 other end contact resistance R4 respectively respectively, triode VT3 collector electrode, ground capacity C1, ground capacity C2, the photo resistance RG other end and power supply VCC, the resistance R4 other end is connecting triode VT2 collector electrode respectively, triode VT3 base stage and triode VT4 base stage, the triode VT2 base stage contact resistance R3 other end, triode VT3 emitter is connecting triode VT4 collector electrode and resistance R5 respectively, the resistance R5 other end connects the G pole of diode D3 positive pole and IGBT pipe respectively, diode D3 negative pole connects diode D4 negative pole, diode D4 positive pole connects the E pole of IGBT pipe and ground connection, and the C pole of IGBT pipe connects ground connection light-emitting diode D1 negative pole by resistance R6.
As the utility model further scheme: described diode D4 is voltage stabilizing didoe.
Compared with prior art, the beneficial effects of the utility model are: the utility model light-operated LED, and circuit structure is simple, and cost is low, and volume is little, is applicable to street lamp.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of light-operated LED.
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, comprises photo resistance RG, diode D1, diode D2, triode VT1, IGBT manages, electric capacity C1 and diode D3, photo resistance RG one end connecting triode VT1 base stage, triode VT1 emitter connects ground capacity C3 respectively, triode VT2 emitter and triode VT4 emitter, triode VT1 collector electrode is contact resistance R3 and resistance R2, resistance R2 other end contact resistance R4 respectively respectively, triode VT3 collector electrode, ground capacity C1, ground capacity C2, the photo resistance RG other end and power supply VCC, the resistance R4 other end is connecting triode VT2 collector electrode respectively, triode VT3 base stage and triode VT4 base stage, the triode VT2 base stage contact resistance R3 other end, triode VT3 emitter is connecting triode VT4 collector electrode and resistance R5 respectively, the resistance R5 other end connects the G pole of diode D3 positive pole and IGBT pipe respectively, diode D3 negative pole connects diode D4 negative pole, diode D4 positive pole connects the E pole of IGBT pipe and ground connection, and the C pole of IGBT pipe connects ground connection light-emitting diode D1 negative pole by resistance R6.
Diode D4 is voltage stabilizing didoe.
Operation principle of the present utility model is: refer to Fig. 1, under dark situations, photo resistance RG resistance decreasing, triode VT1 conducting, the electric current that power supply VCC produces in addition makes triode VT2 conducting, under the effect of power supply VCC through resistance R2, the rapid conducting of triode VT3, be in control positively biased and conducting through resistance R5, IGBT, light-emitting diode D1 lights; When there is illumination in the external world, photo resistance RG resistance becomes large, and triode VT1 ends, and mechanism is contrary, and VT2 conducting makes VT4 conducting, and power supply VCC is added in IGBT pipe through resistance R5, and IGBT is managed and turns off rapidly, light-emitting diode D1 extinguishes.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
