Since entering the 21st century, with the rapid development of industry and the rapid development of various industries such as petroleum, chemical, mining, etc., lighting fixtures are more and more widely used in production, storage, and rescue, and there are more and more varieties. At this time, the LED explosion-proof lamp is very important to prevent accidental explosions in explosive gas hazardous locations.
LED lighting has appeared in China's lighting industry, its performance far exceeds that of traditional lamps, and it has gradually become the main lighting fixture in life and industry. No matter from the performance point of view or from the perspective of energy saving or other aspects, LED explosion-proof lights are more popular in the market than previous lamps.
Since ordinary lighting fixtures inevitably generate electric sparks or form hot noodles during work, once they encounter explosive gas mixtures at the production or rescue site, they will cause explosions and directly endanger the lives of national property and citizens Safety. Therefore, as a widely used lighting fixture, its explosion-proof technical problems have long aroused people's general attention and high attention. Under such circumstances, explosion-proof lamps came into being.
At first, everyone chose incandescent lamps, mercury lamps, metal halide lamps, and sodium lamps. These light sources generate a lot of heat, and their lifetime is generally around one year, and the power factor is not too high. With the advent of LED explosion-proof lamps, long-life, high-efficiency light sources have also been developed, but its light-emitting principle limits the energy conversion efficiency, the use of inductive ballasts to electronic ballasts, and compensation capacitors. None can really save energy.
The second-generation light source refers to energy-saving lamps and electrodeless lamps as the light source of explosion-proof lamps. But compared to LED explosion-proof lamps, energy-saving lamps are not durable enough. After users use it, they find that the light source is often damaged, and the maintenance cost is relatively high, so customers are reluctant to choose energy-saving lamps as light sources. The same electrodeless lamp has also developed rapidly at this stage, and has proposed the characteristics of long service life, which caters to the needs of customers. There are also quite a variety of types, including high-frequency electrodeless lamps, low-frequency electrodeless lamps, ring-shaped, round, bubble-shaped, and explosion-proof lamps and lanterns. But its shortcoming is that the light decay is greater, and the brand has not done it, but some people still use it.
The third-generation light source can be said to be the current LED light source. The technology, small size, and flexible light source combination of LED explosion-proof lamps using LED light sources have brought a comprehensive update to the market of explosion-proof lamps, which can be said to be epoch-making. With the development of the LED market, the cost price of LED explosion-proof lamps has been declining, and the performance has become more and more stable.
