One of the very important explosion -proof principles of ED explosion -proof lamps is to limit the temperature of the shell surface, the surface of the parts or electronic component of the components or the surface of the electronic component of the explosive gas, and limit the temperature of the electrical contact surface than the smaller point ignition temperature or ignite the ignition temperature or ignite. temperature. The principle is the same as the explosion -proof lamp, but the light source is LED light source, which refers to a lamps taken by various measures such as explosive explosive mixtures such as explosive gas environment, explosive dust environment, gas gas, etc. LED explosion-proof lamps are currently more energy-saving explosion-proof lamps, which are widely used in oil field-chemical factory-oil.
