|20130010453||COLOR COMPENSATION IN LED LUMINAIRES - A luminaire in which color or brightness differences of light sources are compensated is provided. The luminaire can include several LED packages providing light to a primary optical component, which directs the light out of the luminaire. Because individual LED packages may output light at slightly different colors and/or brightness, the luminaire can include a secondary optical component having different materials that modify the color, brightness, or both of the output light. The secondary optical component can serve as a filter positioned between the LED packages (e.g., between a LED module) and the primary optical component, or between the primary optical component and the user, or above the primary optical component. The secondary optical component can be constructed by providing colorfast inks, phosphors, or quantum dots on a clear substrate or on a surface of the primary optical component. The materials can be disposed in a non-uniform manner.||01-10-2013|
|20120257383||LIGHT WELL PROVIDING WIDE ANGLE UP LIGHTING IN A LED LUMINAIRE - A luminaire providing wide angle up lighting using light wells is provided. The luminaire can include a frame having a center plate and side walls. LED modules can be disposed adjacent to opposite side walls such that the LED modules are oriented towards each other. The luminaire can include light wells positioned over each of the LED modules such that light emitted by the LED modules may be reflected within the light wells until it is transmitted by a lens region of the light well at a wide angle relative to the nadir of the luminaire. The light wells can include reflective layers disposed on all surfaces surrounding the LED modules, and a transmittance lens region through which light, emitted by the LED modules as point sources, can exit the fixture as a surface of light. Light emitted by LED modules and light wells disposed on opposite sides of the luminaire can provide a bat wing distribution of up light.||10-11-2012|
|20120230019||REMOVABLE OPTICAL COMPONENT FOR LUMINAIRE - This is directed to a luminaire having a removable inner accessory and optical component. A luminaire can include a base and an outer accessory through which light generated by a light source placed in the base is transmitted. To customize the light emitted by the luminaire, an inner accessory having an optical component can be placed within the outer accessory. The optical component can be tuned to provide a light pattern corresponding to an environment in which the luminaire is placed. Because all of the components used to create the luminaire, other than the optical component, are standard, the luminaire can be easily constructed with a default optical component, but also easily customized at a minimal cost. In addition, the optical component can be recessed relative to the outer accessory to improve optical performance of the luminaire.||09-13-2012|
|20120176784||LUMINOUS RETROFITTING DOOR - A luminous retrofitting door for use in a troffer-style fixture is provided. A door having a frame operative to be mounted in a troffer is provided. The door may retain one or more optical components including, for example, a LED module, a light guide array, a diffuser, and a reflector, that combine to emit light in a uniform manner from the troffer.||07-12-2012|
|20120170260||OFF-AXIS ILLUMINATION LED LUMINAIRE - This is directed to a LED light fixture having a shaped light guide array with a CPC reflector for directing light off-axis, and methods for constructing the same. A LED light fixture includes a LED module providing light and an elongated light guide array placed adjacent to the LED module. The elongated light guide array can include a curved outer surface through which light is emitted into an environment. To further control the output of light, and to direct light off-axis, the light guide array can include a CPC reflector disposed around a boundary or periphery of the light guide array. The CPC reflector can be angled such that light is directed at angles above a cut-off angle by which the reflector is rotated about a focus.||07-05-2012|
|20120155116||HIGH EFFICIENCY EDGE-LIT LIGHT FIXTURE - This is directed to a LED light fixture having a light guide array with a retroreflective element used to redirect light into the light guide array, and methods for constructing the same. A LED light fixture includes a LED module providing light and an elongated light guide array placed adjacent to the LED module. Light emitted by the LED module propagates through the light guide array and is redirected by the light guide array into the environment of the fixture. To prevent light from propagating through the end of the light guide array opposite the LED module, the light guide array can include angled facets forming a retroreflective element at an end of the light guide array for redirecting light back into the LGA.||06-21-2012|
|20120092856||EXTRUDED WIDE ANGLE LENS FOR USE WITH A LED LIGHT SOURCE - This is directed to a lens for use with a LED light source. The lens can be placed on a top surface of a light fixture to direct light emitted by a LED module at a wide angle relative to the top surface of the fixture. The lens can include an elongated trench in which several LED light sources can be placed in a line such that light emitted within the trench is re-directed by the lens. The lens can include one or more knobs extending over the trench to facilitate diverting emitted light in a more lateral direction, as opposed to vertical direction. In some cases, the lens can be constructed using an extrusion process by which a lens having a constant cross-section allowing for a wide angle radiation pattern is provided.||04-19-2012|
|20110205738||TROFFER-STYLE LIGHT FIXTURE WITH CROSS-LIGHTING - This is directed to a troffer-style light fixture using a LED light to cross-light internal surfaces of the troffer. In particular, this is directed to a troffer-style fixture having several receptacles for receiving LED modules. The modules can be inserted in the fixture such that some light emitted by the LED modules is directed towards an opposite surface of the fixture, causing light from opposite LED modules to mix as light is emitted from the fixture (e.g., cross lighting the fixture environment. The resulting light transmitted and reflected by the troffer can have softer qualities than direct light emitted by a LED module, and enhance the aesthetic appeal of light provided by the fixture. In some embodiments, one or more optical treatments can be applied to internal surfaces of the fixture to enhance the light output by the fixture.||08-25-2011|
