Paper Title:
Package for Side Emitting LED
  Abstract

A wide angle light-deflected lens combining collimation and total internal reflection (TIR) optical mechanics for LED package is proposed. Utilizing angle-dividing method the angle of emitting distribution of LED chip was cut into several angular zones and then a light-collimating curve surface with corresponding declined plane performing TIR for the collimated incident ray was designed. Thereby, the light-deflected lens, consisting of multi pairs of collimating curve surfaces and declined planes, can achieve wide-angle deflection of light emitting from LED chip. The design rule and experiment results of the lens with optimization optical design are demonstrated and discussed in this paper.
