  • Patent number: 8529096
    Abstract: A mechanical interface for a glass bulb is provided. The mechanical interface includes a connector and an optical mount. The connector is in contact with the glass bulb. The connector may be a separate component attached to the glass bulb, or may be a continuous part of the glass bulb, such that the connector is itself made of glass. The optical mount is configured to receive the connector. In so receiving, the optical mount operatively couples with the connector so as to secure the glass bulb in a position. The optical mount is also configured to attach to a lamp housing. A solid state light source retrofit lamp may thus be formed of a lamp housing including a solid state light source light engine and its required components, a glass bulb, and a mechanical interface for the glass bulb.

  • Patent number: 8492961
    Abstract: A heat sink assembly (216) includes a heat sink (218) having an upper surface (220), a lower surface (222), a non-metal-core circuit board (224) disposed in register with the upper surface (220), and at least one solid state electronic component (SSEC) (226) electrically coupled to the circuit board (224) such that an underside (228) of each SSEC (226) is not in confronting relationship with the circuit board (224). A first thermal interface material (232) is disposed between and thermally coupled to the underside (228) of the SSEC (226) and the upper surface (220), the first thermal interface material (232) being electrically and thermally conductive. A second thermal interface material (236) is disposed in thermal communication with the lower surface (222) and spreads heat to the second heat sink (104), the second thermal interface material (236) being electrically insulating and thermally conductive.

  • Patent number: 8419225
    Abstract: An LED lamp (10) includes a heat sink (12), an electrical interconnector (18), an electronics module (16), and a light module (14). The electrical interconnector (18) is disposed in a passageway (32) extending between first and second regions (24, 26) of the heat sink (12) and includes contacts (66) exposed within the first and second regions (24, 26). The electronics module (16) is adapted to be selectively attached within the first region (24) and includes a first electrical connector (64). The light module (14) is adapted to be selectively attached within the second region (26) and includes at least one light emitting diode (LED) (34) and a second electrical connector (38). The first and second electrical connectors (64, 38) are adapted to selectively form an electrical connections to the contacts (66) to provide power from a power source to the LED (34) of the lighting module (14).
