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 touch control LED, comprises resistance R1, light-emitting diode D1, triode VT1, electrode slice M, one-way SCR VS and electric capacity C1, resistance R1 one end connects A pole and the power supply VCC of one-way SCR VS respectively, resistance R1 other end connecting luminous diode D1 positive pole, and light-emitting diode D1 negative pole is contact resistance R6 respectively, electric capacity C4 and triode VT1 emitter, triode VT1 base stage is by resistance R8 connecting electrode sheet M, and triode VT1 collector electrode is contact resistance R2 respectively, electric capacity C2 and triode VT2 collector electrode, the resistance R2 other end is contact resistance R3 respectively, the G pole of electric capacity C1 and one-way SCR VS, the resistance R3 other end connects electric capacity C3, triode VT2 base stage contact resistance R5, resistance R5 other end connecting triode VT3 collector electrode, the triode VT3 base stage respectively contact resistance R6 other end and resistance R7, the resistance R7 other end connects the electric capacity C4 other end respectively, triode VT3 emitter, the electric capacity C3 other end, triode VT2 emitter, the electric capacity C2 other end, the electric capacity C1 other end and light-emitting diode D2 negative pole, light-emitting diode D2 positive pole connects the K pole of one-way SCR VS.
Power supply VCC voltage is 5V.
Operation principle of the present utility model is: refer to Fig. 1, power supply VCC mono-tunnel is directly added on one-way SCR VS, separately leading up to resistance R1, LED is added on triode VT1 and voltage stabilizing didoe VD7, and electric capacity C4 sets up the direct voltage of 5V.Triode VT1 ends at ordinary times, and corresponding VS turns off, and D1 lights luminescence and carries out power supply instruction, and as staff Touching electrode M, export a string low level pulse, VT1 constantly becomes conducting from cut-off, and result VS obtains trigger voltage and conducting, and D2 obtains electroluminescence.
Due to the effect of electric capacity C2, continuation is kept conducting state by VS, and after VS conducting, corresponding C2 both end voltage actual measurement is about 1.6V, this voltage charges to electric capacity C3 through resistance R3, after certain hour, and corresponding triode VT2 conducting, electric charge on result C2 is released, and VS turns off, and D2 extinguishes.
VS closes and has no progeny, and Rectified alternating current, by resistance R1, D1, sets up again the direct voltage of 5V very soon on electric capacity C4.
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.
