Guide: LED lamp as a new type of lamp, people's life can not be separated from him, but the LED lamp shell and the LED lamp damage reasons why people do not necessarily understand, I will introduce below.
The outer casing of the LED lamp is:
LED lights are characterized by high efficiency, environmental protection and long life. However, people who use LED lights will find that LEDs are very light, so it is easy to make light energy into heat, making LED lights very hot. At this time, if the LED or the like does not dissipate heat as quickly as possible, its life will be greatly reduced.
Many LED manufacturers use aluminum housings for LED lights. The aluminum casing is easy to dissipate heat, beautiful in appearance and light in weight, and many high-end electronic products are made of aluminum. For example, the company's laptop "Mac Pro" high-end computer series products use an all-aluminum casing, which is easy to dissipate in a laptop computer, so that the computer does not even have a fan.
The LED lamp uses an aluminum casing to increase the life of the wick and make the LED lamp look good. However, the aluminum lamp cup is relatively expensive to manufacture, and the production cost is high. The lamp cup needs to be processed by a lathe. Therefore, some high-quality, medium-quality LED lamps will use aluminum lamp housings.
Another common LED luminaire housing is a plastic housing. Due to the low cost of plastic shells, some low-end LED fixtures use a plastic casing. However, the plastic case is not easy to dissipate heat, and the plastic is easily melted and sublimated when it is heated to generate harmful gases. Therefore, Europe, North America, and Japan do not use plastic casings. Due to the high demand for cheap LED lamps in some parts of the country, the plastic casings are sold in large quantities in China.
What are the causes of LED lamp damage:
1. The voltage of the current is unstable, and the increase of the power supply voltage is particularly likely to cause the destruction of the LED lamp. There are many reasons for the sudden rise of the voltage. The quality of the power supply or the improper use of the user may cause the power supply voltage to suddenly rise. high.
2. The power supply path of the lamp is partially short-circuited. This is usually caused by a short circuit in a part of the line or other wires that increase the voltage in this place.
3. It is also possible that the LED lamp is damaged due to its own quality and thus a short circuit, and its original voltage drop is transferred to other LEDs.
4. The heat dissipation effect of the lamp is not good. We all know that the lamp light is a heat dissipation process. If the temperature inside the lamp is too high, the LED characteristics will be deteriorated. This also makes it easy to damage the LED lights.
5. It is also possible that the water inside the lamp is in the water because the water is electrically conductive, which will short the line of the LED lamp.
6. The anti-static work was not done at the time of assembly, so that the inside of the LED lamp has been damaged by static electricity. Despite the application of normal voltage and current values, it is extremely easy to cause damage to the LED lamp.
