A kind of energy-saving LED door bell lamp, comprise key switch K, transformer W, rectifier bridge T and electric capacity C1, one end of described button K connects 220V alternating current, the winding N1 of the other end connection transformer W of button K, the other end of the winding N1 of transformer W connects the other end of 220V alternating current, one end of the winding N2 of transformer W connects the port one of transient voltage suppressor diode DW and rectifier bridge T, the port 3 of rectifier bridge T connects the other end of the other end of transient voltage suppressor diode DW and the winding N2 of transformer W, the port 2 of rectifier bridge T connects electric capacity C1, loudspeaker B, resistance R1 and LED group H, the other end of LED group H connects the anode of unidirectional thyristor Q1, the negative pole of unidirectional thyristor Q1 connects the other end of electric capacity C1, resistance R4, triode V1 emitter, electric capacity C2, the port 4 of rectifier bridge T and the pin Q1 of chip IC 1, the other end contact resistance R2 of resistance R1, the other end of electric capacity C2, the pin VDD of chip IC 1, the pin S1 of the chip IC 1 and pin S2 of chip IC 1, the other end of the control pole contact resistance R4 of unidirectional thyristor Q1, the other end of resistance R2 and the pin Q of chip IC 1, the collector electrode of the other end connecting triode V1 of loudspeaker B, the base stage contact resistance R3 of triode V1, the other end of resistance R3 connects the pin O/P of chip IC 1, the model of described chip IC 1 is KD-1000.
As preferred version of the present utility model: described resistance R4 is photo resistance.
Compared with prior art, the beneficial effects of the utility model are: the utility model doorbell circuit adds LED light device on the basis of common doorbell circuit, make open LED while unlatching doorbell, convenient people within doors checks situation outdoors, simultaneously add voltage stabilizing element and light-dependent control element in circuit, make circuit have simple, the convenient and practical advantage of saves energy, structure.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of energy-saving LED door bell 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, a kind of energy-saving LED door bell lamp, comprise key switch K, transformer W, rectifier bridge T and electric capacity C1, one end of described button K connects 220V alternating current, the winding N1 of the other end connection transformer W of button K, the other end of the winding N1 of transformer W connects the other end of 220V alternating current, one end of the winding N2 of transformer W connects the port one of transient voltage suppressor diode DW and rectifier bridge T, the port 3 of rectifier bridge T connects the other end of the other end of transient voltage suppressor diode DW and the winding N2 of transformer W, the port 2 of rectifier bridge T connects electric capacity C1, loudspeaker B, resistance R1 and LED group H, the other end of LED group H connects the anode of unidirectional thyristor Q1, the negative pole of unidirectional thyristor Q1 connects the other end of electric capacity C1, resistance R4, triode V1 emitter, electric capacity C2, the port 4 of rectifier bridge T and the pin Q1 of chip IC 1, the other end contact resistance R2 of resistance R1, the other end of electric capacity C2, the pin VDD of chip IC 1, the pin S1 of the chip IC 1 and pin S2 of chip IC 1, the other end of the control pole contact resistance R4 of unidirectional thyristor Q1, the other end of resistance R2 and the pin Q of chip IC 1, the collector electrode of the other end connecting triode V1 of loudspeaker B, the base stage contact resistance R3 of triode V1, the other end of resistance R3 connects the pin O/P of chip IC 1, the model of described chip IC 1 is KD-1000.
Resistance R4 is photo resistance.
Operation principle of the present utility model is: during use, push button K switch, 220V alternating current becomes direct current and powers to doorbell circuit after transformer W step-down, rectifier bridge T rectification and electric capacity C1 filtering, transient voltage suppressor diode effectively can eliminate the peak voltage that city's electro-mechanical wave produces, increase the stability of power supply, direct current after resistance R1 for chip IC 1 provides direct-current working volts, after IC1 energising work, export music electrical signal from two output, a road is amplified rear drive loud speaker BL through V1 and is sent musical sound; Another road makes the control pole being added in unidirectional thyristor Q1, if be now daytime, the resistance of photo resistance R4 is very little because of illumination, therefore unidirectional thyristor Q1 not conducting, only when insufficient light, to the conducting that just can be triggered at thyristor Q1, control LED lamp H flashing, achieve doorbell and light-operated lighting two ore control.
