    Abstract: 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.

    Abstract: 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.

    Abstract: Disclosed is an example of a system for selectively influencing the circadian system of a human being, or other human stimulus factor, while simultaneously making minimal shifts to a specified operational parameter of the light source, such as correlated color temperature (CCT), color rendering index, look on a fixture, net lumen output, or a power consumption requirement. An example involves image processing to produce drive signals for emitters of a source array in a luminaire and an associated illumination control function to continuously meet a specific melanopic lux or circadian stimulus value, while adjusting/optimizing one or more other operational parameters of the source emitter outputs to achieve or maintain the operational parameter, such as light output level or power consumption, to within some acceptable degree of tolerance.

    Abstract: 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.

    Abstract: 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.
