This RD&D project is a three year team effort to develop a hybrid solar lighting (HSL) system
that transports day light from a paraboloidal dish concentrator to a luminaire via a large core
polymer fiber optic. The luminaire can be a device to distribute sunlight into a space for the
production of algae or it can be a device that is bination of day lighting and florescent
lighting for office lighting. In this project, the sunlight is collected using a one-meter paraboloidal
concentrator dish with two-axis tracking. The secondary mirror consists of eight planar-
segmented mirrors that direct the visible part of the spectrum to eight fibers (receiver) and
subsequently to eight luminaires. This results in about 8,200 lumens incident at each fiber tip.
Each fiber can illuminate about m2 (180 ft2) of office space. The IR spectrum is directed to a
thermophotovoltaic array to produce electricity. This report describes eleven investigations on
various aspects of the system. Taken as a whole, they confirm the technical feasibilit
