Abstract

The invention relates to a thunder-resisting temperature-controlling light-dimming LED (Light Emitting Diode) lamp which comprises three parts, namely a thunder-resisting rectifying circuit (100), a pulse generation circuit (200) and an LED assembly (300), wherein the thunder-resisting rectifying circuit (100) is a four-port network which is provided with a first input end (N1), a second input end (N2), a first output end (T1) and a second output end (T2); an AC (Alternate Current) voltage is accessed between the first input end (N1) and second input end (N2) of the thunder-resisting rectifying circuit (100); one end of the pulse generation circuit (200) is connected with the first output end (T1) of the thunder-resisting rectifying circuit (100), and the other end of the pulse generation circuit (200) is connected with the positive end of the LED assembly (300); and the second output end (T2) of the thunder-resisting rectifying circuit (100) and the negative end of the LED assembly (300) are both connected with an earth circuit (E).

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to an LED lamp pulse driving power supply capable of lightning resistance, temperature control and dimming, which has three functions of lightning resistance, automatic temperature control and dimming. Background technique [0002] Because of the advantages of energy saving, environmental protection, long life, fast response, rich colors, and controllability, LED lamps are recognized as the best way to realize energy saving and consumption reduction of lamps by promoting LED lamps. Japan estimates: If half of Japan's incandescent and fluorescent lamps are replaced with LED lamps, it will save Japan 6 billion liters of crude oil equivalently every year! Some people even think that: LED light is one of the most important inventions of human beings after Edison invented the incandescent light bulb. [0003] Lamp housing (or lampshade), Light Emitting Diode (Light Emitting Diode) components (...
