Abstract

White Light Emitting Diodes (LEDs) will play an important role in future electric lighting technology. The white LEDs have a high power output, a long lifetime, and high power efficiency. Consequently, they are drawing considerable attention. Our group has proposed an indoor visible-light communication utilizing white LED lights. White LEDs are utilized not only as a lighting source but also as an optical transmitter in the proposed system. However, the systems are confined to an application of one-directional communication like background music transmission or guide of art collections in museum. In such systems, uplink is not considered. In this paper, we propose an uplink system using a corner cube modulator for visible-light communication. It makes use of the light reflected by the corner cube reflector with high reflected power, as communication media for uplink. The proposed system is promising for high-speed communication as well as it can avoid shadowing.
