| 20090021931 | LED LUMINAIRE FOR GENERATING SUBSTANTIALLY UNIFORM ILLUMINATION ON A TARGET PLANE - A luminaire includes a fixture housing, a plurality of LEDs disposed on a mounting surface in the fixture housing, and at least one reflector disposed in the housing. A center of each LED is positioned along a line and each LED faces towards an associated target surface that is vertically spaced from the luminaire. The at least one reflector includes first and second reflective surfaces. Each reflective surface is configured with respect to the line on which the LEDs are positioned so that the first reflective surface and the second reflective surface each reflect light from each of the LEDs in a substantially same direction that is offset from a vertical axis. | 01-22-2009 |
| 20090021936 | LINEAR LED ILLUMINATION SYSTEM - A linear LED light module and system includes a heat sink, a printed circuit board, a plurality of LEDs, a power supply housing, a flexible electrical conductor, a first electrical connector, a second electrical connector, and a power supply. The heat sink is elongated in an axial direction along a longitudinal axis that is parallel with a greatest dimension of the heat sink. The PCB is in thermal communication with the heat sink and includes circuitry. The plurality of LEDs mount to the PCB and are in electrical communication with the circuitry of the PCB. The power supply housing connects to the heat sink. The flexible electrical conductor includes at least two wires that are configured to accommodate an AC line voltage of at least 120 VAC. The first electrical connector is at a first end of the electrical conductor. The second electrical connector is at a second end of the electrical conductor. The second connector has a configuration that complements the first connector so that the second connector can connect to an associated adjacent first connector of an associated adjacent LED module to allow a plurality of similar LED modules to be mechanically and electrically connected to one another. The power supply is disposed in the power supply housing and in electrical communication with the circuitry of the PCB and the electrical conductor. The power supply is configured to receive the AC line voltage from the electrical conductor and to convert the received AC line voltage to a lower DC voltage for delivery to the circuitry of the PCB to drive the LEDs mounted on the PCB. | 01-22-2009 |
| 20090168395 | DIRECTIONAL LINEAR LIGHT SOURCE - An illumination apparatus includes a linear array of light emitting diode (LED) chips disposed on a support. A linear reflector assembly has a light coupling reflector portion and a one dimensional light collimation or focusing portion. The linear reflector assembly is secured to the support parallel with the linear array of LED chips. An encapsulant is disposed in the light coupling reflector portion of the linear reflector assembly and pots the LED chips. An elongate phosphor element is disposed over the encapsulant such that the light coupling reflector portion and the encapsulant enhance light coupling between the LED chips and the elongate phosphor element, and the one-dimensional light collimation or focusing portion one-dimensionally collimates or focuses light emitted by the combination of the LED chips and the elongate phosphor element. | 07-02-2009 |
| 20100079998 | DECORATIVE LIGHT FIXTURE INCLUDING COOLING SYSTEM - A decorative light fixture includes a light engine and a shroud. The light engine includes a heat sink and a light source in thermal communication with the heat sink. The shroud covers the light engine to define an air path between an air inlet and an exhaust. The air inlet is disposed vertically below the exhaust. The air path is shaped to direct air over the heat sink and to exit the shroud above the light engine. | 04-01-2010 |
