摘要: A luminaire includes a housing, light-emitting diodes and a light guide. A lateral direction from a top side to a bottom side of the housing is a preferred direction. A front side of the housing forms an aperture. The light guide substantially spans the aperture. In operation, the LEDs emit light toward the preferred direction, which light enters a light coupling surface of the light guide, where it propagates and is substantially retained by total internal reflection. The light guide includes light extraction features to redirect a portion of the light out of total internal reflection, so that some of the light exits the housing through the aperture. The light extraction features redirect some of the light so that more of the light exits the aperture between a normal direction of the light guide and the preferred direction, than between the normal direction and the non-preferred direction.

摘要: A dual output downlight luminaire includes a housing that forms at least a first cavity. A partition extends from a portion of the housing and at least partially forms a boundary between the first cavity and an annular second cavity. A first light source emits a first light that is centered about an optical axis and propagates toward a first output aperture. An optic redirects the first light to form a first light beam that exits the luminaire through the first output aperture. A concentrated portion of the first light beam subtends an angle of 60 degrees or less and is centered about the optical axis. A plurality of second light sources, within the second cavity, emit a second light that exits the luminaire through an annular second output aperture. The first and second light sources are independently controllable with respect to each other.

摘要: A light fixture may include a light source and an optical element, such as a light transmissive waveguide and/or a diffuser, having a surface forming a light output surface of the light fixture. The optical element is located to receive light from the source and is configured to supply the light for illumination, via the output surface. In an example of the fixture having a waveguide, the source is coupled to supply light to at least one of the lateral surfaces of the waveguide. At least the output surface of the optical element has a three-dimensional compound curvature and a perimeter that includes two or more edges connected at vertices.

摘要: A light fixture example includes a housing, a light source in the housing and a diffuser. The diffuser is supported by the housing at a distance from the source so as to receive light from the source and diffuse the light for illumination. The diffuser has a three-dimensional compound curvature and a perimeter with at least two edges connected at vertices. Each such edge is a two-dimensional plane curve. The at least two edges are not coplanar with each other. In some examples, a back panel of the housing may have a similar three-dimensional compound curvature and perimeter.

摘要: A composite light source includes a plurality of illumination panels, that emit light of a fixed color and a variable luminous intensity. Over time, the luminous intensities of at least two of the illumination panels vary, while a combined luminous intensity of the illumination panels remains about constant. Another composite light source includes a plurality of illumination panels that emit light. Each illumination panel of at least a first subset of the plurality of illumination panels emits the light with a first luminous intensity, and each illumination panel of at least a second subset of the plurality of illumination panels emits the light with a second luminous intensity that is different from the first luminous intensity.

摘要: An annulus shaped luminaire includes an annular structure that includes one or more luminous panels, and transition structure that couples a support structure of the luminaire with the annular structure. The one or more luminous panels emit light that illuminates an area adjacent to the luminaire.
