Optical waveguide concentrator and illuminating device

摘要

An optical waveguide concentrator and photocuring device with the optical waveguide concentrator having at least one solid optically transparent member for combining the output radiant energy from a plurality of optoelectronic light emitting devices mounted in a circular array facing the solid optically transparent member with the optically transparent member having an input surface, an output surface and a sloping surface intersecting the input and output surface to form an acute angle and with with each optoelectronic light emitting device having an optical axis directed parallel to or inclined relative to the longitudinal axis of the concentrator. The geometry of the solid optically transparent member may be conical or hyperbolic with the sloping surface tapered to form a tapered angle of between 5° and 15°.
