Abstract:
An optical waveguide concentrator for combining the output radiant energy from a plurality of optoelectronic light emitting devices with minimal loss of radiant energy to the surrounding atmosphere comprising at least one solid optically transparent member having an input surface, an output surface, a sloping surface intersecting the input and output surfaces to form an acute angle, an inclined surface extending from the input surface and intersecting the sloping surface to form an acute angle to the longitudinal axis of the concentrator, with said plurality of optoelectronic light emitting devices mounted in a substantially circular array such that some or all of the light emitting devices face said inclined surface with the remainder facing said input surface and with some of said optoelectronic light emitting devices having an optical axis directed parallel to or inclined to the longitudinal axis of the concentrator.
