Abstract

A novel sensing and tracing technology used for the sun-lighting system is reported in this paper. The system is composed of an azimuth angle sensor, an optical fiber, a sunlight coupling unit, and a sunlight tracing control unit. A hollow-core plastic fiber is designed and fabricated and used to receive and transmit the sunlight. A cone-shape optical coupler is designed and used to trap in more sunlight. Compare with the traditional sensing and tracing technology, both of the receive angle of the optical fiber and the coupling efficiency of the sunlight to the optical fiber are substantially increased, and therefore the requirement for the sensing and tracing control is reduced. Of course the cost of the optical fiber sun-lighting system is also reduced. This new sensing and tracing technology has been used in an optical fiber sunlighting system, the sunlight could be transmitted a length of 50m to 100m. The application of this optical fiber sunlighting in an underground garage would be introduced.
