Edison LED bulbs suppliers china

Because LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, safe voltage and low voltage, long service life, etc., and low energy consumption; therefore, high-power white LED is an explosion-proof lamp, especially An ideal electric light source for portable explosion-proof lamps.

LED explosion-proof lamp, patent zone road sealing technology; more in line with national explosion-proof new technology. The utility model relates to an electrical device used in a special industry, which mainly solves the lighting problem, and comprises a lamp housing, a lamp cover disposed at the front end of the lamp housing, an illuminant and a battery disposed inside the lamp housing, and a switch disposed on the surface of the lamp housing, wherein the switch is characterized in that The illuminant is a high-power LED module, and a wide voltage input driving circuit is arranged between the illuminant and the battery; the wide voltage input driving circuit comprises a constant current chip, the constant current chip and the battery form a power module, and the LED module is connected On the constant current chip, the power module and the LED module are glued together; ultrasonic welding is performed between the lamp cover and the lamp housing.
