The basic principle of LED explosion-proof lights is the same as other explosion-proof lights. Its principle is based on the explosion-proof concept and fire protection type of the European standard EN13463-2002 "Non electrical equipment for environmental use - Part 1: Basic methods and requirements". Explosion proof type is an explosion-proof type that takes measures to allow internal combustion and prevent flame propagation. It is a commonly used explosion-proof type. Moreover, many increased safety explosion-proof lamp components, such as drive power supply, lamp holder, interlocking switch, etc., also use explosion-proof structures. Electrical equipment with explosion-proof shells is called explosion-proof electrical equipment. If a mixture of gases enters the explosion-proof shell and is ignited, the explosion-proof shell can withstand the pressure of the internal gas mixture and prevent internal combustion to the shell. The propagation of peripheral mixtures is a gap explosion-proof principle, A structure designed based on the principle of using metal gaps to prevent the spread of flames and the temperature of cooling products, achieve flame extinction and cooling, and suppress expansion. 96% of the electrical energy of incandescent lamps is generated by heating. 70-80% of electrical energy is dissipated in the form of thermal radiation (infrared), and 5-10% is transmitted to the bulb housing through thermal conduction. Therefore, the temperature of the wick can reach up to 2500 degrees, while the outer surface temperature can reach over 200 degrees. The light emitted by LED lights rarely contains infrared, so there is no thermal radiation. The chip temperature is over 200 degrees, and the outer surface temperature is basically imperceptible. At 20CM of a 100W incandescent light, you can feel a very obvious heat sensation. LED lights can be touched with your hand, and you can hardly feel the heat, which is also known as a "solid cold light source" and will not ignite flammable gases. Therefore, LED explosion-proof lights are intrinsically safe. Explosion proof and intrinsically safe LED explosion-proof lights are safer than other explosion-proof lights..
