In one aspect, a light pipe is disclosed, which comprises a curved light-guiding waveguide including an input surface configured to receive light and an output surface configured for the light to exit the curved light-guiding waveguide through the output surface; and a plurality of lateral surfaces extending from the input surface to the output surface, wherein an envelope of the curved light-guiding waveguide is generated by a rotation of the input surface around a rotational axis; and the rotational axis is collectively parallel to at most one of the plurality of lateral surfaces.

Low-profile color-mixing lightpipe

In one aspect, an optical system for delivering light into an optical fiber is disclosed, which comprises a phosphor-converted white light source for generating white light, a red light emitting diode (LED) for generating red light, and a light-delivery system for delivering at least a portion of said white light and said red light into an input port of an optical fiber.

CRI-booster white laser fiber source

A solar collector is disclosed in which a light pipe having an optical axis and extending from a proximal end configured to receive sunlight to a distal end, and a plurality of reflective elements optically coupled to the light pipe. Each of the reflective elements is configured to direct at least a portion of sunlight incident thereon into the light pipe via the proximal end substantially parallel to the optical axis for a plurality of positions of the sun in the sky. Baffles coupled to the reflective elements further enhance the collectors ability to increase the light collected.
