The difference between LED explosion-proof lamps and explosion-proof lamps

LED explosion-proof lamps are different from explosion-proof lamps; they have different light sources; they are used; new LED technology;

LED explosion-proof luminaires are the same as explosion-proof luminaires. Unlike the explosion-proof luminaires, the light source uses LEDs. Various specific measures are taken to prevent ignition of surrounding explosive mixtures such as explosive gas environments, explosive dust environments, and gas gases.

One of the very important explosion-proof principles of LED explosion-proof lamps is to limit the temperature of the surface of the casing, parts or electronic components in contact with explosive gas and explosive dust, and to limit the temperature of the electrical contact surface below its minimum ignition temperature or ignition temperature. .

Advantages and applications

Because LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat generation, small power consumption, safe low voltage and long service life. Therefore, high-power white light LEDs are explosion-proof lamps, especially portable explosion-proof lamps. A very ideal electric light source for lamps.

LED explosion-proof lamps belong to a type of electrical equipment used in special industries, which mainly solves the lighting problem. It includes a lamp housing, a lamp cover provided at the front end of the lamp housing, a light emitter and a battery provided inside the lamp housing, and a switch provided on the surface of the lamp housing. , Which is characterized by:

The light-emitting body is a high-power LED module. A wide-voltage input driving circuit is provided between the light-emitting body and the battery. The wide-voltage input driving circuit includes a constant current chip. The constant current chip and the battery form a power module. The LED module is connected to the constant On the chip, the power module and the LED module are glued together; ultrasonic welding is performed between the lampshade and the lamp housing.

It utilizes the characteristics of LED's low heat generation to achieve intrinsically safe explosion-proof, and the LED light source has a long life; the battery maintains constant brightness at the end of full charge and discharge; the heat dissipation device is installed on the lamp housing, which can realize the effective heat dissipation of the LED module , To ensure the stability of use, suitable for mining, petroleum, railway, flood prevention and other industries.

Applicable to areas 1 and 2 of explosive gas environment, IIA, IIB, IIC dangerous places.
