20120319616 | SOLID STATE LIGHT FIXTURE WITH A TUNABLE ANGULAR DISTRIBUTION - A light fixture may include LEDs that each emits light into a particular zone on a lens, where each zone has its own focal properties. Each LED may be grouped into one (or more) subset(s) that corresponds to the zone(s) struck by its emitted light. The LEDs may be selectively electrically controllable, so that the amount of light transmitted through each zone may be controllable by the electrical control system of the fixture. Because light transmitted through different zones emerges from the fixture having different widths, the electrical control system can directly control the amount of light emerging at each width. By mixing relatively narrow light with relatively wide light in the proper proportions, the electrical control system of the fixture may produce light having any desired angular profile between “narrow” and “wide”. One may think of the fixture having a controller that features both a dimmer, which can control the optical power or brightness of the fixture | 12-20-2012 |
20120320588 | EDGE-LIT LIGHT PANEL HAVING A DOWNLIGHT WITHIN A LINED INDENTATION IN THE PANEL - A light fixture and method for producing downward-propagating illumination are disclosed. A downward-facing panel may produce diffuse light. The panel may be generally flat and may have an indentation, where the indentation may have a lining that also produces diffuse light. The panel and the lining may have essentially the same luminance, so that the indentation may be less visible for orientations other than directly below the indentation. The fixture may have a downlight recessed into the indentation, which may produce a directional beam that emerges downward from within the indentation. The directional beam may have a brightness controllable separately from the diffuse light, such as a dedicated dimmer switch. The indentation may be at the center of the panel. The panel may be incorporated into a ceiling tile, and may be bundled as part of a kit that can also include ceiling tiles with panels that don't have a downlight. | 12-20-2012 |
20120320626 | EDGE-LIT LIGHT FIXTURE INCORPORATING A DOWNLIGHT AND HAVING A UNIFORM EXTERNAL APPEARANCE - A light fixture and method for producing downward-propagating illumination are disclosed. The fixture includes an edge-lit lightguide illuminated from its perimeter. The lightguide has a light extractor, such as a dot pattern on its bottom surface, which extracts a portion of the light from inside the lightguide and directs it to a diffuser. The diffuser randomizes the direction of the extracted light and forms diffuse light. The fixture also includes a downlight, arranged above the lightguide and producing a downlight beam downward. The downlight beam transmits from the top face through the bottom face of the lightguide and emerges from the bottom face of the lightguide as a directional beam. The downlight beam has a downlight beam footprint. The light extractor has a light extractor area that excludes the downlight beam footprint, and the diffuser has a diffuser area that also excludes the downlight beam footprint. The fixture can produce both diffuse light and a directional beam, while maintaining a generally uniform external appearance. | 12-20-2012 |
20140232292 | ILLUMINATION TECHNIQUES AND DEVICES - Illumination techniques and related devices are disclosed. In some cases, a lighting device configured as described herein may include a front luminaire configured to emit white light and a back luminaire configured to emit colored light. The lighting device can be operatively coupled with controller circuitry programmed or otherwise configured, for example, with one or more algorithms which control the light output of the front and/or back luminaire so as to provide tunability. In some cases, device output may be controlled so as to: (1) simulate lighting conditions/patterns corresponding to the daytime/nighttime on Earth; (2) support/alter physiological processes; and/or (3) provide a specific ambient lighting for a given space. In some instances, a system of multiple such lighting devices can be provided, and in some cases, communication between constituent lighting devices may be provided. In some instances, the lighting device may be mountable as a sconce or other lighting fixture. | 08-21-2014 |
20150084513 | TECHNIQUES AND GRAPHICAL USER INTERFACE FOR CONTROLLING SOLID-STATE LUMINAIRE WITH ELECTRONICALLY ADJUSTABLE LIGHT BEAM DISTRIBUTION - Techniques and user interfaces (UIs) are disclosed for controlling a solid-state luminaire having an electronically adjustable light beam distribution. The disclosed UI may be configured, in accordance with some embodiments, to provide a user with the ability to control, by wireless and/or wired connection, the light distribution of an associated solid-state luminaire in a given space. The UI may be hosted by any computing device, portable or otherwise, and may be used to control any given light distribution capability provided by a paired luminaire. In accordance with some embodiments, the user may provide such control without need to know details about the luminaire, such as the quantity of solid-state lamps, or their individual addresses, or the address of the fixture itself. In some cases, the disclosed techniques may involve acquiring spatial information of the space that hosts the luminaire and/or providing user-selected distribution of light within that space. | 03-26-2015 |

20150085475 | SOLID-STATE LUMINAIRE WITH ELECTRONICALLY ADJUSTABLE LIGHT BEAM DISTRIBUTION - A luminaire having an electronically adjustable light beam distribution is disclosed. In some embodiments, the disclosed luminaire includes a plurality of solid-state lamps mounted on one or more surfaces of a housing. The lamps can be electronically controlled individually and/or in conjunction with one another, for example, to provide highly adjustable light emissions from the luminaire (e.g., pixelated control over light distribution). In some cases, a given solid-state lamp may include tunable electro-optic componentry to provide it with its own electronically adjustable light beam. One or more heat sinks optionally may be mounted on the housing to assist with heat dissipation for the solid-state lamps. The luminaire can be configured to be mounted or as a free-standing lighting device, in accordance with some embodiments. In some embodiments, the aperture through which the lamps provide illumination is smaller than the distribution area of the solid-state lamps of the luminaire. | 03-26-2015 |
