Abstract
Under the background of the global energy shortage and environmental protection requirement, the nations all over the world are trying to develop green energy-conserving lighting technology. As a revolutionary energy-saving lighting technology ,LED lighting is developing rapidly. However, the LED power requirement is also improving. High efficiency, high power factor, the safety standards of isolation,EMI standard, high reliability, high current control accuracy, low cost, small volume is becoming the key of LED power’s index. Compared with ordinary LED, RGB LED has more colors, so of course the effect is better, and its application is more than white LED.This paper introduces the concept of LED power and the process of RGB LED’s production.Due to the RGB LED’s high brightness and it’s flexible color shift, this system can be widely used in lighting and decoration,etc.
