  • Patent number: 7810955
    Abstract: 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.

  • Publication number: 20070236956
    Abstract: At least two light emitting diodes emit a non-parallel light beam. A condensing system, operationally coupled with the light emitting diodes, receives the emitted non-parallel light beam and converts the received non-parallel light beam into a parallel light beam. A non-imaging concentrator includes an input surface which collects the parallel light beam, and an output surface, which includes phosphor material and outputs light.

  • Publication number: 20060071329
    Abstract: In a chip package (10, 10?, 110, 210), first and second electrical power buses (14, 14?, 16, 16?, 114, 116, 214, 216) are each formed of an electrical conductor having a chip bonding portion (20, 22, 120, 122, 220, 222) and a lead portion (26, 26?, 28, 28?, 126, 128, 226, 228) extending away from the chip bonding portion. The chip bonding portions of the first and second electrical power buses have edges (32, 34, 132, 134, 232, 234) spaced apart from one another to define an extended electrical isolation gap (40, 140, 240). A plurality of chips (42, 44, 46, 142, 143, 144, 145, 146, 147, 148, 242) straddle the extended electrical isolation gap and are electrically connected with the first and second electrical power buses to receive electrical power from the first and second electrical power buses.
