  • light emitting diode lamp with light pipes
    Patent number: 6991355
    Abstract: An LED light source has a housing having a base. A core projects from the base; is substantially cylindrical and is surrounded by tubes. The core and the base are arrayed about a longitudinal axis. A circuit board in the base supports LEDs. Each of the LEDs is positioned with one of the tubes in a one-to-one relationship at one end of the core. A heat sink is positioned in a heat-transferring relationship with the circuit board and a first reflector is attached to another end of the core. To direct the light emitted by the LEDs from the source to the reflector, the interior of the tubes can be plated with a highly reflective material. In one embodiment, each of the tubes is fitted with a light guide, each light guide extending from a position immediately above one of the LEDs to a position adjacent the reflector.

  • Miniature reduced mercury HID lamp
    Patent number: 6967444
    Abstract: Superior color stability in a miniature HID lamp can be achieved by reducing the size of the lamp, reducing the mercury concentration, reducing the salt concentration and increasing the heat to the lamp seal. In general the result concentrates the salts in the central, lower section of the lamp envelope and displaces them from the hot spot and electrode roots were deleterious chemical reactions can occur that are believed to subsequently reduce lamp performance.
