What is LED explosion-proof light?
LED explosion-proof lamp is a kind of explosion-proof lamp, its light source is LED. It takes various specific measures to prevent the ignition of explosive mixtures around, such as explosive gas environment, explosive dust environment, gas gas, etc .
An important explosion-proof principle of LED explosion-proof lamps is to limit the temperature of the surface of the shell, parts or electronic components in contact with explosive substances, and ensure that the temperature of the electrical contact surface is lower than the minimum ignition or ignition temperature . Since LED is a solid state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, safe working voltage and long service life, so it has become an ideal electric light source for explosion-proof lamps, especially portable explosion-proof lamps.

What are the types of LED explosion-proof lights?
- flameproof : The use of flameproof housing to prevent internal explosion from propagating to the outside .
- Increased safety : under normal operating conditions will not produce arc, sparks, or dangerous high temperatures, and further safety measures .
- positive pressure : prevents external explosive gases from entering by keeping the pressure inside the housing higher than the ambient pressure.
- intrinsic safety : by limiting the circuit energy, it is ensured that the electrical spark and thermal effect generated under normal operation and specified fault conditions cannot ignite the specified explosive mixture 1.
- dust explosion-proof type : specially used for dust explosion dangerous environment .
LED explosion-proof flat table lamp for which scenes?
- Petrochemical industry : such as petrochemical equipment, oil platforms, gas stations, oil pump rooms, transfer stations, oil fields, etc., these places exist flammable and explosive gases and dust, need highly explosion-proof lighting equipment .
- chemical industry and mine : in chemical plants, mines, tunnels and other industrial sites, due to the presence of potential explosive gas or dust, as well as harsh environment, high humidity, dust and other characteristics, LED explosion-proof flat desk lamp can provide safe and reliable lighting .
- storage site : such as warehouses and other storage of flammable and explosive materials, also need to use LED explosion-proof flat desk lamp to ensure safety .
Factors affecting the life of explosion-proof lamp
- Wick quality : high quality LED wick is the basis of explosion-proof lamp life, impurities and lattice defects will affect its life .
- heat dissipation : good heat dissipation design is the key, the heat generated by LED lighting needs to be dissipated in time, otherwise it will accelerate the aging of the device .
- ambient temperature : too high or too low ambient temperature will have an adverse effect on the explosion-proof lamp life, especially the life of the electrolytic capacitor is greatly affected by temperature .
- Power quality : A stable power supply is critical. Fluctuations in current or voltage can damage leds and other components .
- lamp design : reasonable lamp design not only meet other indicators, but also consider heat dissipation and light source stability .
- use and maintenance : frequent switching, lack of regular maintenance and maintenance will also affect the life of explosion-proof lamps.
