Open publisher page 0 citations

Abstract

It is presented in this paper that the simulation study of multi-shadow phenomenon of multi-LED-chips lighting with Trace Pro,aiming to reduce the size of the multi-shadow.The relatively small size of LED chips enables us to replace traditional light sources with multiple LED chips and to reduce the size of the multi-shadow through multiple light source superposition.Schematic models of LED illumination with different numbers of LED chips and different arrangements are established respectively.Irradiance maps of the table are analyzed.Analyses show that increasing the numbers of LED chips while the total length of the length of the array remains unchanged can reduce the size of the multi-shadow,and the more compact the arrangement is the smaller the size of the multi-shadow is,which provides theoretical basis for optimizing lamp performance design.
