Summary:LED energy-saving and explosion-proof lamps are a kind of explosion-proof lamps. Its principle is the same as that of explosion-proof lamps. However,
LED energy-saving and explosion-proof lamps are a kind of explosion-proof lamps. Its principle is the same as that of explosion-proof lamps. However, the light source is LED light source, which refers to the various methods used to avoid igniting explosive mixtures around explosive gas background, explosive dust background, gas gas, etc. A lamp with a specially designated treatment method.
A very important principle of explosion protection in LED energy-saving and explosion-proof lamps is to limit the temperature of the outer shell, the outer parts of the parts or the outer surface of electronic components that are in contact with explosive gases and explosive dust, and to limit the temperature of the outer surface of electrical contact below its minimum ignition temperature or lead. Burning temperature. Because the LED belongs to the solid-state cold light source, it has the advantages of high electro-optical conversion rate, low calories, low power consumption, safe and low-voltage office voltage, and long operating life, because this high-power white LED is an explosion-proof lamp, especially A very ideal electric light source for portable explosion-proof lamps.
LED energy-saving explosion-proof lamps belong to a special kind of electrical equipment used in the industry. They mainly solve lighting problems. It covers the lamp housing, the lampshade set at the front end of the lamp housing, the flash body and dry batteries set in the lamp housing, and the lamp housing. The switch on the outside of the shell is characterized by:
The flash body is a high-power LED module. There is a wide voltage input drive circuit between the flash body and the dry battery; the wide voltage input drive circuit covers a constant current chip. The constant current chip and the dry battery form a power module. The LED module is connected On the constant current chip, the power module and the LED module are glued together; the lampshade and the lamp shell are ultrasonically welded.
It uses the unique place of low calorie LED to successfully achieve substantial safety-level explosion-proof, and the life of the LED light source is long; the dry battery maintains eternal and constant brightness at the end of the discharge and the end of the discharge; the radiator can be successfully installed on the lamp shell. Realize the tube heat dissipation of the LED module to ensure the stability of use, and it is suitable for lighting in various industries such as coal mines, fuels, railways, and flood control. It is suitable for use in hazardous locations in Zone 1 and Zone 2, and explosive gas atmospheres of IIA, IIB, and IIC.
