Abstract: A substrate for a solid state lighting module has a plurality of serrated finger sections extending from an interconnecting base. The substrate may be formed from a single rectangular sheet by cutting away material between adjacent finger sections of a symmetrical second substrate to form the finger sections of the substrate. Parallel linear rows of solid state light sources may be disposed along the length of each finger section. For example, the solid state light sources may be disposed proximate to points of sawteeth at the edges of the finger sections.

Abstract: An illumination optical system with a tunable beam angle (IOSTBA) is presented to achieve different beam angles without changing parts. The IOSTBA includes a light source and a post having a proximal end and a distal end, the proximal end in optical communication with the light source, an internal area of the post having a reflective surface. Also shown is a diffuser disposed across the end of the post, the diffuser in optical communication with the post and a reflector surrounding a portion of the post, the reflector movable along a length of the post. A position of the reflector along the post determines a beam angle of a resulting light beam exiting the IOSTBA. The system features a simple and cost effective optical design which works with a variety of light sources, including color mixing and champing strategies.

The light source mounting surfaces extend laterally inward from the respective bottom edges. The plurality of solid state light sources is disposed along the pair of light source mounting surfaces proximate the pair of specularly reflecting lateral sides. These emit light, which travels upward to the top side and is also specularly reflected by the lateral sides toward the top side. The top side diffusely reflects the light out of the luminaire.
