1. Sudden rise in power supply voltage. There are many reasons for the sudden increase of the power supply voltage, such as power supply quality problems and improper use by users.
2. The short circuit of components or printed wires or other wires in the circuit forms a partial short circuit of the power supply path of the LED explosion-proof lamp, which increases the voltage in this area.
3. The LED explosion-proof lamp is damaged due to its own quality. When a short circuit is formed, its original voltage drop will be transferred to other LED explosion-proof lamps.
4. The internal temperature of the lamp is too high, which makes the performance of the LED explosion-proof lamp worse.
5. The inside of the lamp enters the water, and the water is conductive.
6. The anti-static work was not done during assembly, which caused the interior of the LED explosion-proof lamp to be damaged by static electricity. Although normal voltage and current are used, LED explosion-proof lights are easily damaged.
These reasons will cause the current of the LED explosion-proof lamp to increase significantly, and soon the chip of the LED explosion-proof lamp will burn out due to overheating. According to our experience, most of the two poles of the LED explosion-proof lamp are short-circuited, and a small part is broken. The voltage drop of each LED explosion proof light is about 3.2v. If it burns out, this series of LED explosion-proof lights do not emit light when the circuit is damaged. If a short circuit occurs, the voltage will be transferred to other LED explosion-proof lamps, causing the current of other LED explosion-proof lamps to become larger, other LED explosion-proof lamps will soon burn out, and even a critical power supply will appear. Minor damage can easily lead to major accidents. LED explosion-proof lights are generally installed on higher ground, which is more difficult to install and more difficult to maintain. Therefore, the protection of LED explosion-proof lights is a realistic need, but it has not been paid attention by everyone at present, and it is also a problem that many people cannot solve.
