Based on hybrid control theory to make white LED with RGB
We have discussed that blue light and phosphor make white before. today we will using other way to make white LED.
Human’brightness sensitivity of Three-color light sources is different when using different wavelength RGB to drive LED.in here the brightest is green light , secondly, is red light, and the weakest is blue light.and do they make white light? the answer is yes. we can make white light with different ratios of RGB light , the percentages of RGB light was red light 30％、green light 59％、and blue light 11％. the bright equation is : Y=0.30R+0.59G+0.11B.
