20100046217 | OPTICAL SYSTEM AND METHOD FOR MANAGING BRIGHTNESS CONTRASTS BETWEEN HIGH BRIGHTNESS LIGHT SOURCES AND SURROUNDING SURFACES - An optical system and method provides at least one, and preferably an array of relatively small, high brightness light sources with a surrounding surface that exhibits brightness, thereby reducing the contrast between the high brightness produced by the light sources and the brightness of their surrounding surfaces. The optical system includes a light waveguide structure that captures a portion of the light from the individual high-brightness light sources, and then re-emits the source light to create brightness in the light sources' surrounding surfaces. The optical system is particularly adapted for use with LEDs, but could be used with other high brightness light sources. | 02-25-2010 |

20100284185 | LOW PROFILE OLED LUMINAIRE FOR GRID CEILINGS - A low-profile luminaire has a planar light source comprised of one or more planar organic light emitting diodes (OLEDs). The OLED light source is supported by a low-profile OLED support structure that lies in a plane. The support structure has a maximum height (H) of about two inches and preferably a height of about one inch or less. It also has perimeter dimensions that allow the luminaire to fit within and to be supported by the T-bar grid of a grid ceiling system. Electrical components for driving and controlling the OLED light source can be provided within the support structure or externally of this structure. | 11-11-2010 |
20110157893 | OLED LUMINAIRE HAVING OBSERVABLE SURFACES WITH DIFFERENTIAL VISUAL EFFECTS - An OLED luminaire has at least one panel structure having a generally planar observable surface and at least one OLED panel having a light emitting surface forming at least a portion of the panel structure and having a sufficiently high lumen output for illuminating a space. The generally planer observable surface of the panel structure, including the light emitting surface of said OLED panel, create visual interest by exhibiting differential visual effects, such as different low luminance patterns or different color patterns, or both, when the OLED panel or panels are driven to a state of illumination. Differential visual effect on the luminaire's panel structure can also be created by the juxtaposition of illuminated OLED panels and non-illuminated fill panels. | 06-30-2011 |
20110249450 | OLED LUMINAIRE HAVING INTENSITY SHAPING FOR OLED LIGHT SOURCE - An OLED luminaire | 10-13-2011 |
20110273886 | LUMINAIRE HAVING NON-REVEALED AREA LIGHT SOURCES - A luminaire has a shell housing with an upper shell section and a lower shell section that form an interior cavity and at least one side opening through which an observer can see into the interior cavity of the shell housing from a position below the luminaire when the luminaire is positioned overhead the observer. The interior cavity has a lower region which is hidden from the direct line-of-sight of an observer below the luminaire. At least one and suitably a plurality non-revealed upwardly facing area light sources, such as OLEDs, are supported on the lower shell section of the shell housing and disposed in the lower region of the interior cavity thereof so as to produce light within the interior cavity and so as to be hidden from the direct line-of-sight of an observer below the luminaire. Upwardly facing non-revealed area light sources can also be provided on the upper shell section of said shell housing for producing light that is directed overhead the luminaire from said upper shell section from additional area light sources that are hidden from the direct line-of-sight of an observer below the luminaire. | 11-10-2011 |
20120018770 | OLED LIGHT SOURCE HAVING IMPROVED TOTAL LIGHT EMISSION - An OLED light source has a reduced area metal cathode such as a fine mesh cathode and a highly conductive electron conduction layer adjacent the cathode that allows for rapid lateral conduction of electrical current beneath the cathode to cause exciton formation over substantially the entire light emitting area of the OLED. By substantially reducing the coverage area of the cathode, cathode-exciton energy transfer (cathode quenching) produced by the presence of a metal cathode can be substantially reduced, and total light output from the OLED increased. | 01-26-2012 |
20120300437 | CONFIGURABLE CEILING LIGHTING SYSTEM - A configurable ceiling lighting system for a grid ceiling comprising at least one and preferably a plurality of driver panels having a bottom and a defined perimeter sized to allow the driver panel to be set into and retained within the grid openings of a ceiling grid. The driver panel has at least one and preferably a plurality of electrical connectors accessible from the bottom of the driver panel. At least one and preferably a plurality of light modules are provided having a light source and an electrical connector complimentary to the electrical connectors of the panel drivers. The light modules can be operatively connected to the bottom of the ceiling panel drivers at selected connection points to produced desired arrays of ceiling lighting fixtures to meet particular lighting needs. | 11-29-2012 |
20130294067 | LIGHTING SYSTEM RECONFIGURABLE BY GESTURAL CONTROL - A luminaire, such as a ceiling suspended luminaire, that can change its shape or some other state or characteristic based on user-input. The changes of shape or other state or characteristic can be achieved by hand gestures, such as moving the hand up and down in the detection field of a sensor. In one aspect of the invention, a suspended luminaire having a flexible sheet form is provided. The shape or attitude of the sheet form luminaire can be changed by exerting a force on one or more attachment points on the luminaire. | 11-07-2013 |
20130294079 | TWO-DIMENSION CONFIGURABLE LIGHTING SYSTEM WITH ENHANCED LIGHT SOURCE PLACEMENT CAPABILITIES - A lighting system having neural hubs that connect to other neural hubs in a manner that allows a lighting system to be configured in a two dimensional pattern that can propagate out from a single neural hub. Straight sections can be provided for use in connection with the neural hubs to enhance the configurability of the lighting system. | 11-07-2013 |
20130300316 | GESTURAL CONTROL DIMMER SWITCH - A gestural control dimmer switch for controlling the illumination level of a light using hand movements comprises a dimmer panel in operative communication with a light, the dimmer panel having a plurality of hand position sensors corresponding to a spectrum of illumination levels of the light, wherein when a hand is detected by the hand position sensors the illumination level of the light is set until the hand reaches a dimmer trigger position when the switch enters a dimming mode during which the illumination level is adjusted to the illumination level corresponding to the hand position sensor the presence of the hand is detected until a release condition is satisfied. | 11-14-2013 |
20130301249 | LOW PROFILE LUMINAIRE FOR GRID CEILINGS - A low-profile luminaire has a light source comprised of one or more organic light emitting diodes (OLEDs), LEDs or other area light sources. The one or more area light sources are supported by a low-profile support structure that lies in a plane. The support structure, which supports the area light source substantially in the plane of the support structure, preferably has a maximum height of about two inches and more preferably a height of about one inch or less. It also has perimeter dimensions that allow the luminaire to fit within and to be supported by the T-bar grid openings of a grid ceiling system. Electrical components for driving and controlling the light source can be provided within the support structure or externally of this structure. | 11-14-2013 |
