Abstract: A lightweight and efficient edge-lit luminaire adapted to be installed in an environment. The edge-lit luminaire includes a housing, a light source disposed adjacent a perimeter edge of the housing, and an optical element having one or more perimeter edges disposed immediately adjacent the light source. The optical element includes a plurality of walls configured to direct light emitted by the light source out of the housing and into the environment.

Abstract: A lighting fixture and method of providing lighting is provided herein that utilizes both direct and indirect light sources. The direct and indirect light sources can be provided in arrays of light emitting diodes (LEDs) oriented along desired axes. In some versions, the light fixtures described herein include a direct lighting array having one or more LEDs oriented to project light downwardly and an indirect lighting array having a plurality of LEDs oriented to project light in a transverse direction. Further, the light fixtures can include an indirect lighting member configured to be illuminated by the plurality of LEDs of the indirect lighting array. Additionally, or alternatively, the light fixtures described herein can include one or more controllers that are configured to independently operate the direct and indirect lighting arrays. Moreover, the indirect lighting array can be configured to emit light in a plurality of colors to visually convey information.

Abstract: A luminaire with uplighting and downlighting capabilities is provided. According to one aspect, the luminaire may include a housing, a light source disposed in the housing, and a lens. The light source may be configured to emit light in a downward direction, and the lens may at least partially cover the light source. An opening may be formed in a top part of the housing and may permit light reflected by an interior surface of the lens to be transmitted in an upward direction from the housing. Optionally, a transparent or translucent cover member may at least partially cover the opening in the top part of the housing.

Abstract: A luminaire that includes a plurality of light emitting diodes (LEDs), a light diffuser having a planar surface facing the LEDs, and a reflector that surrounds a cavity formed between the light diffuser and the LEDs. The plurality of LEDs emit light toward the light diffuser, from which a first portion of the emitted light transmits through the light diffuser and a second portion of the emitted light reflects off of a planar surface of the light diffuser to the reflector.

Abstract: A luminaire that includes a plurality of light emitting diodes (LEDs), a light diffuser having a planar surface facing the LEDs, and a reflector that surrounds a cavity formed between the light diffuser and the LEDs. Also disclosed is a method of distributing light that involves emitting light towards a light diffuser having a planar surface having a reflective coating, scattering a first portion of the light with the light diffuser, reflecting a second portion of the light with the light diffuser, reflecting the second portion of the light with a first reflective surface back towards the light diffuser, and scattering the second portion of the light with the light diffuser. Further disclosed is another method of distributing light that involves emitting light toward a light diffuser and reflecting a portion of the emitted light toward the light diffuser via a reflector.
