Abstract

This paper designs a color temperature adjustable LED based on structured fluorescent film which uses the structured pattern of the fluorescent film’ s thickness. Through the adjustment of the thickness of the fluorescent film, when the blue LED chip excites the structured fluorescent film, it can form alternate arrangement of the LEDs with White light of different color temperatures. By changing the working current of the two groups of LEDs, we can achieving the control of LED’s color temperature. And the simulation results show that ranging from 3000K to 6500K.
