Why white DIP546 led lamps deteriorate quickly than other color leds?

White color leds are combined with blue color led and yellow phosphor powder. The white led quality and lifespan are clearly affected by the quality of blue led chip and yellow phosphor powder.

Let’s see a case of price led changers at Gas stations of Mexican Petroleums:

   Let’s have it analyzed: among red, green, blue and amber led chips, blue led chip is the weakest one to emit light.  So, large electric current is needed to drive the blue led chip and the yellow phosphor powder. When this happens, the lifespan of white leds will become much shorter than other color led chips.

Our solution for your while 18" digit led segment is: large blue led chips are used. Large led chips with small electric current. The ideal and thorough way to solve the problem is to persuade your clients to accept other colors such as RED, AMBER or GREEN color.  Here RED color and AMBER color are strong recommended for you, as not only red and amber led chips, but also green led chips as well, they themselves emit color. They do not need YELLOW PHOSPHOR POWDER.

Let's turn our sight to traffic lights: RED, GREEN and AMBER. 

   Why all the traffic lights are red, green and amber color? Because the three colors have the best penetration power in bad weather environments (rainy days, foggy days or snow days). The wavelength of red color is 520nm - 530nm. Eyes of human being are very sensitive to red colors. Red and amber color has the best performance in bad environmental weather.

Technology of Red color led chip develops fast and maturely than white led chips;

Red color DIP546 led lamps are much easier to purchase than white led lamps;

Amber/yellow color is also welcomed by most of people in the world. It has similar features as red color.
