Abstract

Hybrid solar lighting (HSL) is a new technology originated by Oak Ridge National Labs (ORNL) for providing daylighting to interior spaces of buildings not contiguous to a roof location. In this approach, solar energy is collected and concentrated by a small dish reflector (approx. 1 sq.m) onto a fiber optic bundle. The fibers within the bundle are routed into the area to be illuminated and the light is distributed from them as desired. Science Applications International Corporation (SAIC) has been supported by the University of Nevada, Reno through a DOE-sponsored development program to assist in development of appropriate and cost-effective solar concentrator systems for this concept. This paper presents the results of SAIC development efforts in this area. Optical analysis of the hybrid lighting system was performed to quantify the tradeoff between the accuracy of the primary mirror and its size required to deliver a particular quantity of light to a receiver. A prototype low-cost dish/tracker system was developed, based on a commercially-available satellite dish reflector and simple, low-cost tracker components (Fig. 1.). The single-unit cost of the prototype system was about $1300 ($520/sq.m), with potential for significant additional reductions in quantity production. Other features and components needed for the hybrid lighting system were also demonstrated on the prototype system, such as automation of clock updating and self-powering of the system from a PV array. This project demonstrated the potential to develop a cost-effective dish/tracker system that ensures economic feasibility of this system.
