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.

Dual output downlight fixture

A luminaire configured for mounting to a grid ceiling system includes first and second portions. The first portion includes a first housing, one or more first mating elements, and a light engine coupled with the first housing that generates light from electrical power, and is oriented to emit the light away from the first housing. The second portion includes a second housing and one or more second mating elements. The second mating elements are adapted to couple with the first mating elements. At least one of the first portion and the second portion includes an electrical receptacle for receiving the electrical power for the light engine. When the first mating elements couple with the second mating elements, the first housing and the second housing together define a cavity for one or more members of the grid ceiling system.

Lighting fixtures and methods for grid ceiling systems

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.

Composite light source systems and methods

A two-component luminaire for illuminating an architectural space includes a housing with a panel that faces the architectural space. A peripheral edge of the housing, having first and second edge segments, forms an output aperture that faces the architectural space. A plane bisecting the output aperture defines a boundary between an indirect lighting region and a direct lighting region. The luminaire includes a primary optical subsystem arranged within the housing so as to be hidden from the direct lighting region by the first panel section, and configured to generate and emit light, through the output aperture, solely into the indirect lighting region, and a secondary optical subsystem, disposed within the housing and configured to generate and emit light through the output aperture.

Recessed luminaire

Embodiments of the invention are directed to wall recessed two-component luminaires. The two components can include a primary optical subsystem and a secondary optical subsystem. The primary optical subsystem can provide indirect lighting, illuminate an architectural space upward toward a ceiling, and/or have greater luminous flux than the secondary optical subsystem. The secondary optical subsystem can provide direct lighting, illuminate an architectural space horizontally and/or downward, provide lit appearance, provide direct view color and/or color gradients, provide direct view luminance and/or luminous gradients, and/or provide lighting for ambience.

Luminaire having multiple illumination panels

A pole luminaire mounts to a base and illuminates an area adjacent to the base. The luminaire includes a core structure having a plurality of side portions that extend vertically from the base, disposed about an elongate, open central shaft. One or more luminaire subassemblies couple with the core structure. Each luminaire subassembly includes a housing with a face panel that defines an aperture, a face plate coupled within the aperture, and a light engine having one or more light emitters. Light is directed through the aperture and the face plate into the area.

Optical systems and methods for pole luminaires

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.

Annulus shaped luminaire

Embodiments of the invention provide for a lighting system for illuminating aisles with shelving. A rail can include a plurality of LEDs that extend along the length of the rail. The rail can be coupled with a node that includes various components along with an egress light source. The LEDs can be used to primarily illuminate the shelving on both or one side of the aisle. The egress light can be used to illuminate the aisle during times of emergency, at night, or when egress may be required.
