In the recent years Visible Light Communication (VLC) has gained great interest due to the rapid developments in Light Emitting Diodes (LEDs) fabrication. Efficiency, durability and long life span of LEDs make them a promising residential lighting equipment as well as an alternative cheap and fast data transfer equipment. The advantages of indoor VLC that is offering illumination and data transmission simultaneously using the existing infrastructure, White LED lamp used as source. The

In this paper we proposed a numerous distribution patterns with different number of LEDs to increase the signal to noise ratio (SNR) and enhanced the uniformity of the illumination. The indoor VLC system is modeled using the proposed pattern and the theoretical analysis is presented. Firstly we compare the normal distribution of the luminous intensity of one locations LED located on the center of room ceiling with our four locations LEDs model. To eliminate spot lighting 8 lactation of LED lamps was proposed. Lastly our novel arrangement using 17 locations has been investigated. A proposed design provide normal distribution which enhance the lighting and communication in whole room. A mathematical model of illumination LEDs has been studied, as well as the basic parameters which are important for the development of the design.
