LED explosion-proof lamp is a kind of explosion-proof lamp, its principle is the same as explosion-proof lamp, but the light source is LED light source, is to prevent the ignition of explosive mixture around such as explosive gas environment, explosive dust environment, gas gas and so on and take a variety of specific measures of lamps and lanterns.One of the very important explosion-proof principles of LED explosion-proof lamps is to limit the temperature of the shell surface, parts surface or electronic components surface 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.As LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat, low power consumption, safe low voltage, long service life and so on. Therefore, high-power white LED is an ideal electric light source for explosion-proof lamps, especially portable explosion-proof lamps.
The luminator is a high-power LED module with a wide voltage input drive circuit between the luminator and the battery.The wide voltage input drive circuit includes a constant-current chip, which forms a power module with the battery. The LED module is connected to the constant-current chip, and the power module is glued to the LED module.Ultrasonic welding is performed between lamp shade and lamp housing.
It makes use of the characteristics of LED low calorific value to realize the intrinsically safe explosion-proof, and the LED light source has a long life. The battery maintains a constant brightness at the end of full charge and discharge; Heat dissipation device is installed on the lamp shell, which can realize the effective heat dissipation of LED module and ensure the use stability. It is suitable for lighting in coal mine, oil, railway, flood control and other industries.
Applicable to explosive gas environment 1, 2, IIA, IIB, IIC dangerous places.
