As preferred version of the present utility model: the model of described optical coupler IC1 is 4N25.
Compared with prior art; the beneficial effects of the utility model are: the utility model anti-interference LED illuminating lamp not only has over-voltage protecting function; and use optical coupler to carry out Phototube Coupling; add the anti-interference of circuit; be provided with emergency light module simultaneously; automatically open emergency light when LED lamp protection disconnects, prevent the inconvenience brought to people's productive life of turning off the light suddenly, therefore there is stable performance, strong interference immunity and advantage easy to use.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of anti-interference LED illuminating 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 anti-interference LED illuminating lamp, comprise transformer W, rectifier bridge T, optical coupler IC1 and relay J, it is characterized in that, the two ends of the winding N1 of described transformer W connect the two ends of 220V line voltage respectively, one end of the winding N2 of transformer W connects the anode of diode D1, the other end of the winding N2 of transformer W connects the pin 2 of electric capacity C1 and optical coupler IC1, the negative electrode of diode D1 connects the other end of electric capacity C1 and the pin 1 of optical coupler IC1, the two ends of the winding N3 of transformer W connect the port one of rectifier bridge T and the port 3 of rectifier bridge T respectively, the port 2 of rectifier bridge T connects electric capacity C2, resistance R7, relay J, the negative electrode of diode D2, the contact J-2 of relay J and the pin 4 of optical coupler IC1, the other end of the contact J-2 of relay J connects LED group H, the other end of resistance R7 connects the contact J-1 of relay J, the other end of the contact J-1 of relay J connects emergency light L, the other end contact resistance R2 of electric capacity C2, the other end of LED group H, the other end of emergency light L, the emitter of triode V1 and the port 4 of rectifier bridge T, the pin 3 contact resistance R1 of optical coupler IC1 and electric capacity C3, the other end of resistance R1 connects the other end of electric capacity C3, the other end of resistance R2 and the base stage of triode V1, the collector electrode of triode V1 connect the anode of diode D2 and relay J the other end.
