The Method of Reflective Fly Eye Lens Design for LED Illuminating Projection System
用于LED照明的反射型复眼设计方法

A pair of reflective fly eye lens with a high brightness LED as light source is put forward for micro-display projector.Because of reflective system,the embodiment is shorter than 20 mm.The uniformity is above 80% and the efficiency of the illuminator is better than 75%.The design method with induced equations for calculating the lens surface is given.Computer simulated results are also presented.
