LED drivers for combined illumination and visible light communications

Abstract

Solid State Lighting (SSL) with High-Brightness LEDs (HB-LEDs) results in energy savings due to high efficacy of HB-LEDs. Energy savings has led to the replacement of traditional lighting systems such as incandescent, fluorescent and metal halide lamps by LED lighting. Unlike traditional lighting sources, the unique properties of LEDs include generation of multiple colors and the ability to modulate at high-speed. Due to these properties, LED lighting will create emerging applications in healthcare, education, agriculture and communications.
