摘要：
The light diffuser with 3D microstructure is one of the high efficient light diffusers used in LED lighting to realize secondary optical design. The aspect ratio (AR), filling coefficient (FC) and arrangement (A) of microstructure plays an important role in the optical property of light diffuser. The experiment results and simulation results obtained from Light Tools software of light diffuser with microsphere structure used in LED light shows that the optical property of diffuser with microsphere structure whose diameter is from 0.1 mm to 1.0 mm, arranged in hexagon is best with AR of 0.22 and the filling coefficient of 100%.
