Therefore, to design the lights with high illumination and uniform has become one of the important courses in the development light industry.
Recently, there are three approaches that are used to design the lamps aiming at the uniform of the light source in the market. One is to be solved by the tube of the light-source, the other is to cover the light with the filter, and another is to attach with the grating construction and preventing from strong light for the purpose of uniform. In this research the last approach is aimed. Grating constructions with different density and geometry shapes are simulated on the software called "Light Tools" to analyze the effect of illumination and uniform.
Through the simulation and analysis of this research, we have some results as following: the best grating curving angle to the uniform is 10 degree; the proper thickness to the uniform is 15mm; and it is useful to the promotion of the uniform, if the reflection rate of the material is over 90%.
