What is LED explosion-proof light?

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.

What are the four technical standards of led explosion-proof lights?

• ‌LED explosion-proof light source ‌ : must use high brightness, high light efficiency, low light decay of the LED chip, and the use of regular channel chip package LED lamp beads. Encapsulated gold wire, phosphor, insulating adhesive, etc. need to use the required materials to ensure the stability and reliability of the light source ‌.
• ‌LED explosion-proof light driver ‌ : LED is a semiconductor component that converts DC electronics into light energy, so a stable drive requires a high-performance power driver chip, and has the power factor compensation function to ensure power efficiency. The quality of the driving power supply is crucial to the whole lamp, a good driving power supply can not only ensure stable DC power supply, but also improve the conversion efficiency, to achieve real energy saving ‌.
• ‌LED explosion-proof light heat dissipation system ‌ : The structural rationality of the shell is the key to the heat dissipation of LED explosion-proof light. Since the LED converts light energy at the same time, part of the electrical energy will be converted into heat energy, it is necessary to dissipate the heat into the air to ensure the stable luminescence of the LED. The advantages and disadvantages of the heat dissipation system directly affect the life of the LED lamp and the speed of light decay ‌.
• ‌LED explosion-proof lamp lens ‌ : The lens has a profound effect on the refractive index of light and the final output luminous flux. High-quality lenses can improve light transmission and reduce light loss. Therefore, when choosing a lens, it is necessary to pay attention to its light transmittance and material, and avoid the use of poor quality lenses resulting in reduced light efficiency or yellowing and other adverse effects ‌.
