Explosion-proof lamps refer to lamps that take various specific measures to avoid igniting surrounding explosive mixtures such as explosive gas environments, explosive dust environments, and gas. One of the most important explosion-proof principles of explosion-proof lamps is to limit the temperature of the surface of the shell, the surface of parts or electronic components that are in contact with explosive gases and explosive dust, and to limit the temperature of the surface of electrical contact to be lower than its ignition temperature or ignition temperature.
Since LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low calorific value, low power consumption, safe and low-voltage operating 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 lamp is a kind of electrical equipment used in special industries, mainly dealing with lighting problems. , which is characterized in that: the illuminant is a high-power LED module, and a wide voltage input drive circuit is arranged between the illuminator and the battery; the wide voltage input drive circuit includes a constant current chip, and the constant current chip and the battery form a power module, and the LED The module is connected to the constant current chip, the power module and the LED module are glued together; the lampshade and the lamp housing are ultrasonically welded.
It uses the characteristics of low calorific value of LED to achieve practical safety level explosion-proof, and the LED light source has a long life; the battery maintains constant brightness at the end of charging and discharging and the end of discharge; the heat dissipation device is installed on the lamp housing to achieve effective heat dissipation of the LED module , to ensure the stability of use, suitable for coal mines, petroleum, railways, flood control and other industries lighting.
