What are the reasons why the luminous words are not bright?
1. Lights are not on: this reason is easy to find, the line is blocked, the transformer is broken, check the line and transformer. Or there is faulty welding.
2. Some are on, some are not: This is the reason for LED lights. Although the LED module is in series, its electrical reason is parallel connection. This prevents one lamp from breaking down and affecting the brightness of all lights. If you break the light, it's fixed. If it is outdoor, not only to use waterproof LED lights, but also pay attention to the sealing of the font.
3. When it was on, it all went out: the reason was that the transformer failed and the LED lamp was burnt out.
The above is about the cause of the luminous word is not bright, I hope to help you.
