[Pu Wan heat Technology - industry, academia, research, sales for the body, is committed to building China green carbon environmentally friendly high-tech entrepreneurs, high heat dissipation, high insulation, low-density, high-performance | is the benchmark for similar products in the enterprise business ! Cooling Kit truly first brand! ! ! ] 60s of last century, Xie Gang LED lights, scientists using the principle of semiconductor PN junction glowing, LED lamp market, research has become the LED light-emitting diode. Was developed by the LED, the materials used are GaASP, its luminous color is red. After nearly 30 years of development, we very familiar with the LED, has been able to issue a red, orange, yellow, green, blue and other colored light. However, white light LED lighting required only after 2000 was developed, where information about the white LED lighting to readers.
