Chapter I: light
Light color

In addition to the luminous efficiency is another important parameter of light and color, and white LED light-emitting principle is the core issue in the blue light and then through the blue excitation light yellow phosphor emission, so that the final mixture into the white, white LED from the spectral point of view Spectrum than the spectrum of natural light is much less, and this problem is the color of the problem. And for the development of the current level of technology in terms of not able to complete the formation of natural light, the complete spectrum of white LED light, which is the core of the light-emitting blue light, shorter wavelength, color temperature higher penetration is poor. LED's penetration is almost always one of its drawbacks, it is almost never completely replace their incandescent reason. In order to solve such a thing CREE launched a warm white, natural white color LED that changes in processing technology of LED, phosphor change, the end result is that the LED light emitted by more "yellow ", The effect is somewhat similar to incandescent bulbs. Common natural white, warm white Q2-5A, Q3-5C is one such LED. The use of LED in the outdoors changed significantly. Now China can buy into the Q3-5C, I have a Q2-5C LED light color is consistent with the light-emitting efficiency, but is slightly hearing. Technology is advancing very bad ah ~ has bought the LED can be found in the country now.
