Spectrum characteristics of white LED

The white LED is composed of a blue LED chip(( In. Ga) N) and a color conversion layer of YAG: Ce3+ phosphors dispersed in a medium such as epoxy resin. other words it mainly assembled by a blue and yellow. Please see Spectrum characteristics photo of white LED as follows;

The wither LED create light of the spectral curve. is indicated by a solid line . View the first wavelength of the peak of the spectral curve. be matched dollar-for-dollar with 460nm，and the blue and their corresponding relationship . the secondly wavelength of the peak of the spectral curve. be matched dollar-for-dollar with 580nm，the 580nm corresponding to the yellow. As you see (white LED), there are two elements: 460nm(blue) and 580nm (yellow) . This would be considered an white . light susceptibility of curve is indicated by a dotted line
