- Dec 07, 2017-

In the the 1960s, scientists used the principle of semiconductor PN Junction luminescence to develop led light-emitting diodes. The LED developed at that time, the material used is gaasp, its luminous color is red. After nearly 30 years of development, we are very familiar with the LED, has been able to emit red, orange, yellow, green, blue and many other colors. However, the lighting required white light led only in 2000 after the development, here to introduce the reader about the lighting with white light led.
