20110267828 | Thermal Trim for a Luminaire - A luminaire with a thermal pathway to reduce the junction temperature of the luminaire's light source, and methods for so doing, are disclosed. The luminaire includes a can, a light engine, and a trim, that define a substantially continuous thermal pathway from the light engine to a surrounding environment. The can defines a can cavity and includes a can end region. The light engine is within the can cavity and includes a light source and a heat sink, including a heat sink end region, coupled thereto. The trim is at least partially disposed within the can cavity and includes a first trim end region coupled to the heat sink end region and a second trim end region coupled to the can end region. Thermal interface material may be located between: the heat sink and the trim, the trim and the can, and/or the heat sink and the light source. | 11-03-2011 |
20120206914 | SOLID STATE LIGHT SOURCE-BASED MODULE CONVERTIBLE BETWEEN LINEAR AND NON-LINEAR SHAPES - A lighting module is provided. The lighting module includes a flexible substrate having a first side and a second side, a plurality of solid state light sources, and a flexible housing. The first side of the flexible substrate has conductive traces. The plurality of solid state light sources is placed on the first side of the flexible substrate. The plurality of solid state light sources is electrically connected to the conductive traces. The flexible housing has at least a first shape, which may be linear, and a second shape, which may be non-linear. The flexible housing includes a flexible superelastic material in an austenite phase. The flexible housing is placed in proximity to the flexible substrate to form the lighting module. | 08-16-2012 |
20120274217 | HYBRID REFLECTOR INCLUDING LIGHTGUIDE FOR SENSOR - A luminaire is providing, having a substrate of a particular shape and a plurality of solid state light sources mounted thereon. The plurality has a measurable characteristic and includes an adjustable solid state light source, such that the characteristic changes in response to adjustment thereof. The luminaire also includes a sensor that detects the characteristic from outputted light, compares it to a baseline value and, based on the comparison, so adjusts the adjustable solid state light source. The luminaire also includes a reflector with a lower edge that conforms to the particular shape of the substrate, and reflects outputted light from the plurality so that it exits past the reflector's upper edge. The luminaire also includes a lightguide having an input that is surrounded by the reflector and captures a portion of the outputted light so as to provide the captured outputted light to the sensor. | 11-01-2012 |
20130155699 | THERMAL TRIM FOR LUMINAIRE - A luminaire with a thermal pathway to reduce the junction temperature of the luminaire's light source, and methods for so doing, are disclosed. The luminaire includes a can, a light engine, and a trim, that define a substantially continuous thermal pathway from the light engine to a surrounding environment. The can defines a can cavity and includes a can end region. The light engine is within the can cavity and includes a light source and a heat sink, including a heat sink end region, coupled thereto. The trim is at least partially disposed within the can cavity and includes a first trim end region coupled to the heat sink end region and a second trim end region coupled to the can end region. Thermal interface material may be located between: the heat sink and the trim, the trim and the can, and/or the heat sink and the light source. | 06-20-2013 |
20130214118 | TORSION-BASED LUMINAIRE SUSPENSION MECHANISM - A luminaire suspension mechanism is provided. The mechanism includes two arms, two friction elements, and a compression element. Each arm includes three segments and two connection points. For each arm, a first segment attaches to a second segment at a connection point, forming a first angle, while the second segment attaches to a third segment at another connection point, forming a second angle. Each friction element is connected to a respective arm's third segment. Each arm's first segment is compressably attached to the compression element, such that a force applied to at least one of the arm-friction element pairs results in the compression element and that at least one pair exerting a suspending force that suspends a luminaire to which the luminaire suspension mechanism is attached within a cavity. The compression element may be a torsion spring, and the angles formed by the arm segments may be obtuse. | 08-22-2013 |
20140254176 | SOLID STATE LIGHTING DEVICE WITH EXTENSIBLE MOUNTING BASE - A solid state lighting device with an extensible mounting base is provided. The solid state lighting device includes a housing and a moveable extension positioned in the housing. The moveable extension is aligned along a longitudinal axis of the solid state lighting device, and includes a closed position adjacent the housing and an open position remote from the housing. A base is affixed to an external end of the moveable extension. The base connects to a corresponding socket in order to provide electrical power to the solid state lighting device. The housing also includes a mechanical actuator therein. The mechanical actuator has a first end, affixed to the moveable extension, and a second end, affixed to the housing. The mechanical actuator allows the moveable extension to change from the closed position to the open position and vice versa. | 09-11-2014 |
20150087174 | MOUNTABLE CONNECTOR BOX FOR ELECTRICAL DEVICE - An electrical connector box, capable of mounting a type of electrical device to a surface, including methods of so mounting, is provided.
