5 common problems in the use of LED letters:
1. The font output power is large, and the energy saving is not obvious.
2. The font part of the stroke, the whole is suddenly not bright or when it is on, it is not bright: after the use of the illuminated word, the local or whole font light source starts to flash, and when it is bright, it does not light until it is completely off.
3. The color is uneven, the color difference is obvious: it is mainly manifested in the large-sized luminous characters made by pure white LED. In the assembly, the performance of the single module is not obvious. After the whole font is assembled, the chromatic aberration is clearly expressed. The whole face is like a map, white, blue and yellow.
4. The color decays very quickly: the color of the newly installed illuminating word is pure and bright, and it can be faded down in less than one year. It is very ugly that the font becomes red and not green and green is not green.
5. Short life of LED: The theoretical service life of LEDs produced by regular manufacturers is generally about 80,000 hours. Nowadays, many of the luminous characters have not been used enough for a year to start replacing LED modules frequently, which brings a lot of trouble and economic loss to customers and advertising producers.
Shenzhen Lanli Optoelectronics specializes in the production of LED letters. It has 6 years of rich production experience, professional technicians to make, effectively avoid the problem of LED luminous characters, and give customers the best LED letters.
