How to avoid the difference in brightness of LED luminous characters

Publisher: Administrator Date:2023-04-15

We can adopt the following solutions to avoid such situations when installing LED luminous characters.
1. Using high-quality power cables to ensure that each wire has the same current intensity.
2. The voltage of the transformer should be suitable, not too small, with low power and insufficient luminous intensity. Use different transformers based on the size of the word.
3. Extra lines should be added for oversized characters to ensure uniform current and avoid uneven light emission.
4. The wiring of luminous characters is connected in series, and the main line pulled out by the power supply is connected to the first character first and then connected to the second character. Later, the current passing through will decrease, and the lower the current, the lower the brightness. Therefore, LED light emitting words are usually connected in parallel, with each word directly connected to the transformer. For larger fonts, it is best to have parallel strokes for each character, so that the brightness of the illuminated text is even.
