The reason and solution of LED light-emitting words not bright

LED light-emitting character is a kind of advertising logo product that uses LED light as the light source. If the light of the light-emitting character in the LED light-emitting character signboard suddenly fails to light up, it will cause problems in the whole signboard, thus affecting the normal operation of the shop. So what are the causes of the light-emitting words not bright? If the LED light is not on, it is a great trouble for customers. In summary, there are several reasons why the light-emitting words are not bright. Let's analyze the reasons and solutions.

Generally, there are several reasons why the LED light-emitting words are not on:

1. Line fault

The probability of line failure causing problems is the highest, especially in outdoor use, high temperature, low temperature or humidity will lead to line aging in advance.

2. LED lamp failure

This problem is rare and often occurs in inferior lamp products.

3. Transformer failure

Transformer can be said to be the heart of glowing words, important and very fragile. It is easy to burn out the transformer in humid or high temperature environment. The transformer failure may lead to unstable voltage and burn out the LED lamp.

4. LED lamp life expired

This situation is the least, because the life of LED lamp is higher than other light source products, the theoretical service life is 100000 hours, and it can work for 10 years continuously.

How can we solve the problem after we know the reason why the LED light is not on?

Method 1. Check the circuit

Check whether the circuit is connected with a universal meter. In case of circuit problems, replace the circuit in time.

Method 2. Replace LED lamp

It is better to change the LED light with the same brand and model. If you change other brands, it may lead to inconsistent light intensity and color temperature, thus affecting the appearance.

Method 3. Replace the transformer

At the same time, it is necessary to analyze the causes of the problems. It is recommended to place the transformer in a dry and low-temperature environment for environmental reasons. If the transformer is burnt out due to overload, it is recommended to replace the transformer with higher power.

Method 4: replace LED light words

If the service life is exhausted, it is recommended to replace all the LED light-emitting character signs, because if you only replace the problem lights, other lights will have problems in succession, so it is better to directly update them.
