Large flux light guides employing discrete annular optics Donaldson, Ross Michael

Abstract

This thesis concerns the development of two new light guides, the annular lens light guide and the annular reflector light guide, into viable light distribution systems. The systems use the theory that guiding light does not require the angular distribution of light to be maintained throughout the guide. It only needs to be periodically reproduced. The theory of both guides is thoroughly developed in two dimensions. With the aid of Monte Carlo ray trace modelling these theories are then extended to three dimensions. Prototypes of both guides are constructed from commercially available materials. The properties and limitations of these guides are investigated via photometric testing and ray trace modelling. The encouraging results prompt further investigation of the guides by means of a public demonstration. One of the guides is installed in a public building to explore the limits associated with such an installation and the appeal of such a system to building occupants.
