We all know that, if it is the phosphor decay, then bound to excite the phosphor 570nm peak wavelength of the yellow green decay, resulting in the chromaticity coordinates of white light LED directional changes to the blue tones, which chromaticity coordinates reduced. After testing, the actual result is that white LED device chromaticity coordinates change but the direction of the yellow tone. Therefore, it can not create white light phosphor decay that the main factor to accelerate. Hold this
