Abstract: A heat sink comprising pin fins extending from a base plate of the heatsink. Some of the pin fins are angled outwardly towards an outer edge of the base plate such that the tips of some of the pin fins may extend beyond the outer edge of the base plate. The distance the outer pin fins extend beyond the outer edge of the base plate can correspond to a maximum diameter of the heatsink. The maximum diameter of the heatsink can be greater than the diameter of the base plate of the heatsink.

Abstract: A recessed wall wash light fixture includes a light source and a hollow light guide. The hollow light guide has a reflective internal surface and forms upper and lower apertures along its upper and lower boundaries. The lower aperture is slanted upwardly in the forward direction. The hollow light guide includes a forward section and a rear section having respective centerlines and wall surfaces. Both of the centerlines are concave with respect to one another, and the wall surfaces extend laterally from the centerlines and curve toward one another. The forward and rear wall surfaces substantially meet one another at midlines that extend downwardly from the upper aperture to the lower aperture.

Abstract: A light engine that includes light emitting diodes mounted on a printed circuit board, which in turn is attached to a heat sink. An optic assembly is positioned over the printed circuit board to direct the emitted light as desired. The light engine can be positioned. within the ceiling within the opening of a mounting frame. In some embodiments, the light engine is retained on the mounting frame such that it can be moved clear of the mounting frame opening.

Abstract: A light engine that allows for customization and easy adjustability of various properties of the distributed light. The light engine includes an optic holder having threads that engage with threads of a mounting ring to allow a lower reflector and/or a diffuser lens to be replaced without removing the entire light engine from the installation. The light engine also includes an upper reflector that interfaces with the optic holder so that the upper reflector also can be easily replaced without removing the entire light engine from the installation.
