The LED light source is blackened and the lamp is not bright, what is the reason?

Led light source blackening is a problem often encountered by major LED companies. However, the blackening of the light source is only the appearance, and the phenomenon of vulcanization, chlorination, bromination, oxidation, carbonization and chemical incompatibility will lead to the blacking of the LED light source. Due to the lack of professional testing equipment and personnel, most LED companies usually rely on experience and speculation when doing blackening failure analysis, and lack of scientific detection data. Today we will explain the reason why the lamp is not bright!

First, the lamp tungsten wire burned out

The first place to check when the lamp is not bright is the tungsten filament in the lamp, because this is the most common cause of the lamp not being bright. So if once the lamp is not lit because the tungsten filament of the lamp is burned out, you only need to replace a new tungsten filament.

Second, the circuit breaker breaks the circuit

Then check if there is a problem with the circuit breaker, because once the circuit breaker burns out, it will cause problems in the circuit. Therefore, it is necessary to use an electric pen to detect whether it can be powered on normally, and if there is a problem, it needs to be replaced immediately.

Third, the electric gate fuse burns out

If there is no problem with the circuit breaker, then you can check whether the fuse of the electric gate has burned out. If the fuse of the electric gate burns out, a new fuse needs to be replaced.

Fourth, the line problem

If the fuse of the electric gate is also intact, you need to check the wiring at home. See if there is a circuit break in any of the lines, causing the lamp to stop lighting up. Because it is possible that rats will bite the wires, it is necessary to find the place where the circuit is broken and then glue it with tape.

The above is the xiaobian for everyone to introduce the reasons for the lamp is not lit, I hope it can be helpful to everyone, if the lamp at home also has this problem, you can refer to the above content to find out the cause and solve.
