LED Lighting Driver IC Design and Encapsulation Material Research

Abstract:

Semi-conductor lighting solution LED is developing quickly and now using wider and wider, and will absolutely replace classical lighting solution because of its high efficiency and reliability,long lifetime and low pollution. The development of white LED lighting solution lead to quickly development of the integrated circuits of driving LED,which creates enormous business opportunities. The thesis first describes I-V characteristics and luminous flux curve of LED and its driving circuit briefly. Then display the working theory of buck converter of LED driver. The thesis brings up a buck-mode LED driver which based on switching power supply technology, supplying higher efficiency compared with other driving mode.
