A lighting system includes first and second component housed within respective first and second housings, and a connector. The first housing defines a first substantially rectangular cross-section that extends from a first end to a second end. The first component is capable of emitting light. The second housing defines a second substantially rectangular cross-section. The second substantially rectangular cross-section extends from a third end to a fourth end. The connector connects the second end with the third end. The connector defines a third substantially rectangular cross-section that is substantially identical to the first and second substantially rectangular cross-sections. The third substantially rectangular cross-section extends along a path from the second end to the third end. The path includes at least one curve of at least fifteen degrees between the second end and the third end, and/or, the substantially rectangular cross-section rotates at least fifteen degrees about the path.

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.

Lighting devices, systems, and methods are disclosed. One lighting device includes a reflector, first and second groups of light emitters, and a controller. The reflector defines a reflective cavity having an opening and an interior surface including first and second features adapted to reflect light in different manners. The first and second groups of light emitters are positioned to emit light through the reflective cavity toward the first and second features, respectively. The controller is coupled to the first and second groups of light emitters, and is configured to control the first group of emitters to emit light having a first value of a characteristic of emitted light, and control the second group of emitters to emit light having a second value of the characteristic of emitted light different from the first value.

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.

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.

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 method of generating drive conditions for light sources to maintain a desired color of a light emitted by the light sources, as perceived by a human observer, over a change in a reference luminance, includes determining a corrected color that produces perception of the desired color, by the human observer, in the presence of the reference luminance; and determining light source drive conditions to produce the corrected color. A light fixture includes multiple illumination panels and control electronics. Some of the illumination panels emit a reference luminance; others emit light of an accent color different from the reference luminance. The control electronics modify an intensity level of the reference luminance, and compensate drive conditions supplied to LED chips that emit the accent color, to compensate the accent color for effects of modifying the intensity level, on human perception of the accent color.

A system for dynamic distribution of bicycle lighting including a plurality of light sources coupled to and under operation of a controller. The controller controls power distributed to the light sources and provides dynamic illumination of the light sources according to bicycle operating condition data, regarding the speed, angle of incline, angle of descent and geographic and terrain conditions in which the bicycle is operated.

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.

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.
