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 to be lower than its minimum ignition temperature or ignition temperature. Its principle is the same as that of explosion-proof lamps, except that the light source is led light source, which refers to the lamps with various specific measures taken to prevent ignition of explosive mixtures around, such as explosive gas environment, explosive dust environment, gas gas, etc. Led explosion-proof lamps are currently the most energy-saving explosion-proof lamps, which are widely used in oil fields, power plants, chemical plants, petroleum - *.
Like people, each LED explosion-proof lamp has its own "identity card", which is marked with the following information:
1. Explosion proof sign.
2. Basic signs: including product name, model, manufacturer name, registered trademark, date of manufacture, etc.
3. Performance safety signs: including rated voltage, current, nominal frequency, light source power and quantity, allowable ambient temperature (this range is only - 20 ~ plus 40 degree ), specific applicable environmental signs (for example, for products only applicable to a certain explosive gas mixture, the name or molecular formula of combustible gas must be marked), classification signs of explosion-proof lamps (such as "numbers").
4. Explosion proof certificate number, which proves that the product has passed the official inspection of the explosion-proof inspection station. Some products have an "X" symbol after the explosion-proof certificate number, which indicates that this product can only be used under certain special safe use conditions. The specified conditions should be clearly and conspicuously indicated in the lamp shell or product manual.
