Five major problems faced by LED luminous characters

Five major problems faced by LED luminous characters

1. Short service life of LED

  The theoretical operating life of LEDs produced by regular manufacturers is generally about 80,000 hours. However, many of the luminous characters have not been used for a year and began to frequently replace the LED modules, which has brought many troubles and economic losses to customers and advertising manufacturers.

  2, color decay very quickly

   The color of the newly installed luminous characters is pure and bright, and the color has been significantly dimmed after less than one year of use. It is very ugly to make the font red or red and green or green.

  3, uneven color, significant color difference

  It is mainly reflected in the large luminous characters made of pure white LED. The single module is not obvious during installation. After the entire font is installed, the color difference is obviously reflected. The entire literal is the same as the map, one piece of white, one piece of blue, and one piece of yellow.

  4. Suddenly off or not on when it is on

   Part of the stroke of the font, the whole is suddenly not bright or when it is bright, it is not bright. After using for a period of time, the luminous characters start to shine in part or the entire font light source, and they are not bright when they are bright, until they are completely bright.

  5. The output power is large, and the power saving and energy saving are not significant.
