Abstract

Visible light communication is one of the Optical wireless communication method. It is a rapidly developing wireless communication technique and uses LEDs for data communication. Due to advancements in the semiconductor industry solid state lighting has become an emerging technology for ubiquitous lighting systems. Because of the improvement in technologies visible light LEDs including white LEDs are becoming more efficient and reliable. Recently these LEDs found a number of applications in the area of lighting and communication. Researchers identified that wireless technology can be embedded to these LED lighting systems by using proper modulation schemes. A novel method for short range optical wireless audio signal communication using white LED lighting system is described in this paper. The system is designed in such a way that the visible LEDs can concurrently be used for lighting and communication applications. A prototype of the system is developed and a pilot study has been carried out in this regard. This paper also discusses the signal to noise ratio and bit error rate of the developed system with the help of experimental and simulational results. The simultaneous use of visible light LEDs for lighting and communication will lead to many interesting and useful applications. Since the system is used for both lighting and communication, energy can be conserved which is having prime most importance in the current century.
