How did the LED white light source come into being?
The color of the light with the relevant fluorescent powder. The phosphor material is downstairs said those things. We know that different atoms impacted excited wavelength is not the same, and electromagnetic waves as the color of nature is not the same. The infrared, ultraviolet, blue, green is in this way! So Bai Guangyuan is led which added to the phosphor 6500K color temperature of about!
LED is very rich in color, through the use of different materials, you can achieve a variety of luminous colors. Such as using GaP:ZnO or GaAaP material red LED, GaAaP material orange, yellow LED, and GaN, blue, LED and so on. In addition, the panchromatic process can be realized by combining the red, green and blue primary colors.
The color of light is related to the cost of fluorescent materials in LED. You can search it on the Internet. There are many materials to refer to
The essence of LED with fluorescent tubes, but also through to excite the phosphor shine. Different fluorescent tube is forcing the current mercury ions and argon atoms make an elastic collision and collision excitation photon and LED lighting, then eliminating the elastic collision in the process.
