Software design of SMD LEDs for homogeneous distribution of irradiation in the model of dark room

Abstract

This article describes wireless optical data networks using visible spectra of optical radiation with a focus on interior areas with direct line of sight LOS (line-of-sight). This type of network represents progressively evolving area of information technologies. Development of lightning technologies based on white power LED was the impulse for wireless optical data networks based on visible spectra of optical radiation (VLC) development. Its basic advantage is the flexibility of users. Users don’t have to stay on one place during the data sharing anymore. Wireless optical data networks represent an alternative solution for metallic and fiber networks [1], [2]. This paper deals with the software simulation of homogeneous distribution of optical irradiation in dark room model, carrying out in LightTools software. First, in previous simulations, the optical source composed from 9 SMD LED’s type LW G6SP-EAFA-JKQL-1 was designed. In various simulations, various numbers and distributions of LED’s were used. These were placed at the ceiling of the dark room. At last, the results of optical irradiation homogeneity are compared.
