LED light-emitting principle (4)

  The emergence of blue LED Torch so that people can use down the line converted the phosphorescent material will be in part the higher energy blue light into other colors. LED Torch sources are only able to completely cover the CIE chromaticity curve all the saturated colors and a variety of colors and phosphorus of the organic LED can be virtually unlimited integration of any color.
   In reliability, LED Torch half-life (ie, light output is reduced to half the initial value of the time) is about 10,000 to 100,000 hours. In contrast, the half-life incandescent light indicating type (here the half-life refers to the number of lamp failure half the time) is typically ranging from 10 million to thousands of hours, depending on the rated lamp current.
