(Summary description)Keywords: LED gas station lights If you are careful when you go to the gas station to refuel, you will find that the lights of the gas station are different from the street lights next to them, because the LED explosion-proof lights used are specially designed lights for the particularity of the gas station, then everyone knows What is the lighting principle of LED gas station lights? In addition, everyone knows that gas stations used metal halide lamps at the beginning, so do you know what advantages LED lamps have over traditional metal halide lamps? The advantages are reflected in better safety, not easy to generate a lot of heat and increase the indoor temperature. It is more energy-saving and has a longer service life. The service life of ordinary metal halide lamps is about 10,000 hours, and the service life of LED light-emitting chips is about 50,000 hours. The light-emitting principle of LED gas station lights:　 LED is a solid-state semiconductor device that can directly convert electricity into light. The heart of the LED is a semiconductor chip. One end of the chip is attached to a Mitutoyo LED on a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire chip is encapsulated by epoxy resin. A semiconductor wafer consists of two parts, one is a P-type [1] semiconductor, in which holes dominate, and the other is an N-type semiconductor, which is mainly electrons. But when the two semiconductors are connected, a "P-N junction" is formed between them. When the current acts on the wafer through the wire, the electrons will be pushed to the P region, where the electrons and holes recombine, and then emit energy in the form of photons, directly converting the electrical energy into light. Small light loss, high light efficiency, long life, no radiation.   The advantages of LED gas station lights compared to traditional metal halide lamps: What are the advantages of LED lamps over traditional metal halide lamps? Better safety, more energy saving and longer service life. The following is a detailed analysis and introduction. 1. The safety of LED lamps is better: compared with metal halide light sources, LED light sources have less heat than metal halide lamps, better safety, and are not easy to generate a lot of heat and increase indoor temperature. The output of LED lamps is DC 35V voltage, which is a safe voltage, and the current is also small. It is not easy to generate electric sparks, and it is safer than metal halide lamps. 2. LED lamps are more energy-saving: the price of LED lamps is higher than that of metal halide lamps, but from the long-term energy saving calculation, the electricity cost saved can generally make up the difference in the price of lamps in about three years. 3. LED lamps have a longer lifespan: ordinary metal halide lamps have a lifespan of about 10,000 hours, 10,000-15,000 hours, and all light sources and electrical appliances must be replaced. The cost of light sources and electrical appliances accounts for about 60% of the lamp. The service life of the light-emitting chip of LED lamps is about 50,000 hours, and the service life of electrical appliances is about 25,000 hours. Generally, the maintenance is only to replace the electrical appliances, and it only needs a few dozen yuan. Reduce maintenance times and maintenance costs due to longer life. 　　The above is the introduction of the light-emitting principle of LED gas station lights and the advantages compared with traditional metal halide lamps.
