Abstract: A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.

Abstract: In various embodiments, packages include one or more lighting devices having electrical contact points, a flexible substrate for supporting the lighting devices, a plurality of electrically conductive traces defined on the substrate and electrically connected to the contact points of the lighting devices, and an adhesive layer mounting each of the lighting devices on the substrate.

Abstract: A luminaire module includes at least one light-emitting element (LEE); a light guide (LG) extending in a first direction from a first end of LG to a second end of LG to receive at the first end light emitted by the LEE and configured to guide the light to the second end; and an optical extractor (OE) optically coupled to LG at the second end to receive light from the LEE guided from the first end to the second end of LG. OE includes a first interface configured to reflect a first portion of the light exiting the LG and transmit a second portion of the light exiting the LG so that the second portion of the light exits OE to an ambient environment in the first direction, and a second interface configured to transmit light incident thereon to the ambient environment in a direction different from the first direction.

Abstract: A variety of light-emitting devices are disclosed that are configured to output light provided by a light source. In general, embodiments of the light-emitting devices feature a light source and an extractor element coupled to the light source, where the extractor element includes, at least in part, a total internal reflection (TIR) surface. Luminaires incorporating light-emitting devices of this type are also disclosed.

Abstract: Illumination devices are described for illuminating a target area, e.g., floors of a room, using solid-state light sources. In general, an illumination device includes a first light guide extending along a first plane, the first light guide to receive light from first light emitting elements (LEEs) and guide the light in a first direction in the first plane; a second light guide extending along the first plane, the second light guide to receive light from second LEEs and guide the light in a second direction in the first plane opposite to the first direction; a first redirecting optic to receive light from the first light guide and direct the light in first and second angular ranges; and a second redirecting optic to receive light from the second light guide and direct the light in third and fourth angular ranges, where the first, second, third and fourth angular ranges are different.

Abstract: An illumination system is described including a plurality of illumination devices, each device including (i) light-emitting elements (LEEs) arranged along a corresponding first axis; (ii) an optical extractor extending along a corresponding longitudinal axis parallel to the first axis; and (iii) a light guide positioned to receive at a first end of the light guide light emitted by the LEEs and guide it to a second end of the light guide. The optical extractor is optically coupled to the light guide at the second end and is shaped to redirect the light guided by the light guide into a range of angles on either side of the light guide. The illumination devices are connected to each other to form a polygon such that the longitudinal axes of the connected illumination devices lie in a common plane.

Abstract: In one embodiment, a solid-state luminaire has a strip of high power LEDs, where each LED emits light into an optical coupler. Light from the optical coupler is then coupled into a light guide. Light coupled into the light guide is mixed and guided to an exit aperture of the light guide. An optical extractor proximate the exit aperture of the light guide redirects light outward, which is optionally redirected generally downward by a secondary reflector that extends outwardly along the length of the light guide. The secondary reflector may be configured to create a variety of light-emission patterns. The luminaire may be hung from a ceiling, in track lighting, used as a pendant or pedestal fixture, or in other applications.
