Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole Embodiment.Embodiment in based on this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Fig. 1 is referred to, in this utility model embodiment, a kind of home intelligent eye protection LED controller, including inductance L1, electricity Hold C1, resistance R1, resistance R2, audion VT1, diode VD1 and electric capacity C4, described electric capacity C1 one end connects inductance L1, electric capacity The C1 other ends connect resistance R1 and audion VT1 base stages respectively, and it is another that audion VT1 colelctor electrodes connect resistance R2, resistance R1 respectively One end and electric capacity C2, the electric capacity C2 other ends connect diode VD1 negative poles and diode VD2 positive poles, diode VD2 negative poles point respectively Not Lian Jie electric capacity C4, photoconductive resistance RG and resistance R5, the resistance R5 other ends connect resistance R6 and audion VT3 base stages respectively, three Pole pipe VT3 emitter stage connects resistance R8, and the resistance R8 other ends connect the G poles of resistance R9 and one-way SCR VS respectively, unidirectional can The K poles of control silicon VS connect the inductance L1 other ends, audion VT1 emitter stages, diode VD1 positive poles, the electric capacity C4 other ends, light respectively The quick resistance RG other ends, the resistance R6 other ends and the resistance R9 other ends, the A poles connecting luminous diode LED of one-way SCR VS Negative pole, LED positive pole connect power supply VCC and resistance R7 respectively, and it is another that the resistance R7 other ends connect resistance R2 respectively End and triode VT3 colelctor electrodes；The diode VD1 is Zener diode.

Operation principle of the present utility model is：Fig. 1 is referred to, inductance L1 is placed in television set or computer power source line is attached Closely, when television set or computer are opened, the electromagnetic field that television set or computer power source line can produce 50Hz around because being powered, coil L1 just picks up the alternating magnetic field of this 50Hz, is exported by C1 so as to produce the corresponding signal of telecommunication, through VT1 amplify after through C2 deliver to by The commutator of VD1, VD2 and C4 composition carries out voltage multiplying rectifier, and corresponding DC voltage is just obtained at C4 two ends, and this voltage is through R5 With R6 partial pressures be added to VT3 conducting, VS can obtain trigger current and open-minded, LED lights luminous；If turned off television set or electricity Brain, because in power line, AC signal interrupts, coil L1 is exported without AC signal, and C4 two ends DC voltage also disappears therewith, and VT3 cuts Only, without trigger current, LED extinguishes VS.Light-operated circuit is mainly made up of photoconductive resistance RG etc., and daytime receives Indoor Natural light because of RG Irradiate and be in low resistance, make the DC voltage decay of electric capacity C4 two ends very big, so VT3 keeps off-state, LED light, Only at night, RG is high resistance, its presence on C4 without impact, so circuit could normal work.
