Explosion-proof lamps and lanterns are used to prevent ignition of explosive mixtures around them, such as explosive gas environment, explosive dust environment, gas and so on.
Luminaires of various specific measures. One of the most important explosion-proof principles of explosion-proof lamps is to limit the contact with explosive gases and dust.
Temperature on the surface of the shell, parts or electronic components and limiting the temperature of the electrical contact surface to be lower than its minimum ignition temperature or ignition temperature
Because led belongs to solid-state cold light source, it has high electro-optical conversion efficiency, low calorific value, low power consumption, safe working voltage, low voltage and service life.
Because of its long life and other advantages, high-power white LED is an ideal electric light source for explosion-proof lamps, especially portable explosion-proof lamps.
LED explosion-proof lamp belongs to a kind of electrical equipment used in special industry. It mainly solves lighting problems. It includes lamp housing, which is set at the front end of lamp housing.
The lampshade, the luminous body and the battery arranged inside the lampshade and the switch arranged on the surface of the lampshade are characterized by:
The luminaire is a high-power LED module with a wide voltage input driving circuit between the luminaire and the battery; the wide voltage input driving circuit includes a constant voltage input driving circuit.
The current chip, the constant current chip and the battery constitute the power supply module, the LED module is connected to the constant current chip, the power supply module and the LED module are glued together; the lampshade
Ultrasound welding is used between the lamp housing and the lamp housing.
It takes advantage of the low calorific value of LED to realize intrinsically safe explosion-proof and long life of LED light source; the battery is LED at the end of charging and discharging.
It keeps constant brightness, and installs a heat dissipation device on the lamp housing, which can realize the effective heat dissipation of the LED module and ensure the stability of use. It is suitable for coal mines and mines.
Oil, railway, flood control and other industries lighting.
