1. Short service life of LED: the theoretical service life of regular manufacturers is about 80000 hours. But now a lot of light-emitting words have not been used enough for a year to start frequent replacement of LED modules, to customers and advertising producers have brought a lot of trouble and economic losses.
2. Fast color fading: the color of the newly installed luminous words is pure and bright, and the color is obviously dimmed after less than a year of use. Luminous character production is the font becomes red not red, green is not green ugly.
3. Color unevenness, color difference is obvious: the production of light-emitting words is mainly reflected in the large volume of light-emitting words produced by pure white LED. When assembling, the performance of a single module is not obvious. After the whole font is assembled, the color difference is obvious. The whole font is like a map, with white, blue and yellow.
4. Some strokes and the whole font are suddenly off or off when they are on: after using for a period of time, the light source of local or whole font starts to flicker, sometimes it is not on, until it is completely off.
5. The output power of the font is large and the energy saving is not obvious.
The above are five common problems in the production and use of luminous characters. I hope it will help you. If you want to know more, please click our official website.
