Abstract
In this article we will introduce a Light Emitting Diode (LED) lighting diffuser plate which diffuses light by optical microstructure. In LED lighting, LED array is the most popular method to attain the illuminance requirement, but this method will produce the glaring and non-uniform illuminance problems. Traditionally, diffuser, which is comprised of diffuser particles, is used to solve the above problems, but it also produces another problem which is low lighting efficiency. Therefore, we use optical microstructure to replace the diffuser particles to solve the problems of LED lighting but only reduce a little lighting efficiency. Moreover, we could control the lighting area of the LED lamp by designing the optical microstructure.
