8.How to Avoid LED Lights Damage?
There are so many advantages of LED lights, such as environmental protection, energy saving, long lifespan, no glare, no radiation and so on. More and more people use LED lights. But they are lack of the knowledge of safe usage of LED lights. Longtop will tell you how to avoid LED lights damage.
At first, if there is no anti-static work for it during assembled, it will make the LED damaged by the static. Although it is applied with the normal voltage and current, it is also easy to cause the LED damage.
Second, there is water in LED lights. Water is conductive, which can make the lamp short circuit. So we must avoid water during the usage.
Third, the power voltage increases suddenly. There are some reasons for it. For example, customers use it in a improper way. It also may be the power supply.
Fourth, the heat dissipation is not good. The temperature of LED light is too high, which can make the LED damaged. So when we choose LED lights, we must pay attention to the heat dissipation, good or bad. That is very important.
