Abstract

There are some limitations to advance technology glaring and luminous Intensity uniformity known as the weak point of existing LED lamp. To improve the two weak points, there have been no special alternative methods so far. Instead, one method which is being used such as the twisting secondary lens or arbitrary structure to remove glaring and improve luminous Intensity uniformity. Based on this academic background, it is necessary to be examined on Technology of Optical System to solve the two weak points by using not complicated but simple methods. This paper will examine the angle of reflection in order to improve luminous intensity uniformity. Also, this research will present the method using lighting analysis program to verify a hypothesis. Through the analysis program, we could understand the simulation analysis method and got some problems about the analysis result. After analysis of causes through reinterpretation of problems, we have reached a conclusion that was changed according to reflectivity and the shape of aspherics by main cause which effected luminous Intensity uniformity and glaring.
