Utility model content
The purpose of this utility model is to provide a kind of acousto-optic touch three to control LED, 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 acousto-optic touch three controls LED, comprise resistance R1, electret B, triode VT1, electric capacity C1, photo resistance R4, electrode slice A and light-emitting diode D1, described light-emitting diode D1 positive pole is contact resistance R3 respectively, power supply VCC, resistance R6, triode VT2 collector electrode, triode VT3 collector electrode and resistance R1, the resistance R1 other end connects electric capacity C1 and electret B respectively, electric capacity C1 other end connecting triode VT1 base stage, triode VT1 collector electrode is the contact resistance R6 other end and electric capacity C2 respectively, electric capacity C2 other end connecting triode VT2 base stage, triode VT2 emitter connecting triode VT3 base stage, triode VT3 emitter is connecting triode VT5 emitter respectively, electric capacity C3 and resistance R5, triode VT5 collector electrode connecting triode VT4 emitter, triode VT5 base stage connecting triode VT4 collector electrode, resistance R5 other end connecting triode VT7 base stage, triode VT7 collector electrode connecting triode VT6 emitter, triode VT6 collector electrode connecting luminous diode D1 negative pole, triode VT6 base stage is the contact resistance R3 other end and photo resistance R4 respectively, the photo resistance R4 other end is connecting triode VT7 emitter respectively, triode VT1 emitter, the electric capacity C3 other end and the electret B other end.
As the utility model further scheme: described power supply VCC voltage is 6V.
Compared with prior art, the beneficial effects of the utility model are: even if the utility model has when illumination by day send the sound, light-emitting diode D1 also can not light, when there is no light to night, as long as send the sound, light-emitting diode D1 can light, and no matter is daytime or night, as long as Touching electrode, light-emitting diode D1 can light, and circuit structure is simple, and cost is low, volume is little, is applicable to very much promoting the use of.
Accompanying drawing explanation
Fig. 1 is the circuit diagram that acousto-optic touch three controls 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 acousto-optic touch three controls LED, comprise resistance R1, electret B, triode VT1, electric capacity C1, photo resistance R4, electrode slice A and light-emitting diode D1, light-emitting diode D1 positive pole is contact resistance R3 respectively, power supply VCC, resistance R6, triode VT2 collector electrode, triode VT3 collector electrode and resistance R1, the resistance R1 other end connects electric capacity C1 and electret B respectively, electric capacity C1 other end connecting triode VT1 base stage, triode VT1 collector electrode is the contact resistance R6 other end and electric capacity C2 respectively, electric capacity C2 other end connecting triode VT2 base stage, triode VT2 emitter connecting triode VT3 base stage, triode VT3 emitter is connecting triode VT5 emitter respectively, electric capacity C3 and resistance R5, triode VT5 collector electrode connecting triode VT4 emitter, triode VT5 base stage connecting triode VT4 collector electrode, resistance R5 other end connecting triode VT7 base stage, triode VT7 collector electrode connecting triode VT6 emitter, triode VT6 collector electrode connecting luminous diode D1 negative pole, triode VT6 base stage is the contact resistance R3 other end and photo resistance R4 respectively, the photo resistance R4 other end is connecting triode VT7 emitter respectively, triode VT1 emitter, the electric capacity C3 other end and the electret B other end.
Power supply VCC voltage is 6V.
Operation principle of the present utility model is: refer to Fig. 1, and (1), when extraneous light is stronger, photo resistance R4 presents low resistance, and triode VT6 base stage is low level, and triode ends, and light-emitting diode D1 cannot be light; (2) when extraneous light is more weak, triode VT6 base stage is high level, triode VT6 conducting, when with hand Touching electrode A, human body sensing electromotive force inputs from A, amplifies charge to C at short notice through triode VT4, VT5, simultaneously, VT7 has base current, VT7 conducting, and light-emitting diode D1 is luminous; After finger leaves A, electric capacity C3 starts electric discharge, and VT7 keeps conducting, and time delay starts, and when C discharge off, VT7 ends, and light-emitting diode D1 extinguishes, and time delay terminates, and delay time is determined by the numerical value of C3 and R5.
(3) acoustic control, to sound signal, make B receive voice signal, then voice signal is converted into the signal of telecommunication, then proceed to triode group, VT1, VT2, VT3 function of current after amplifying makes it charge in electric capacity C3, and make VT7 conducting, if now VT6 also conducting, light-emitting diode D1 is just light, the electric discharge charging of electric capacity C3 achieves delay function, and this circuit can be used in the occasions such as stair-corridor.Manual and acoustic control effect can be realized easily if can normally work.
(4) it should be noted that R4 must be arranged on light-emitting diode D1 according to less than place, otherwise light-emitting diode D1 light after again can automatic distinguishing.
