Abstract

The existing indoor optical wireless communication systems can not provide good wireless coverage uniformity and are not suitable for commercial applications.Two distributed light design schemes were proposed to solve the above problems,which increased the group number of LED array,and then increased the uniformity of light distribution of every group.The simulation results indicate that with the same number of LED chips,the distributed light design scheme is superior to the traditional one in uniformity of wireless signal coverage and complexity of commercial implementation,and can avoid the coverage valley.
