Jarl J. Johansen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Light emitting diode lighting device
    Patent number: 8274241
    Abstract: A lighting device comprises a mounting head having multiple facets each configured to retain an associated Light Emitting Diode (LED). The LEDs are mounted to the facets with a thermally conductive metal pad and thermally conductive adhesive. A connector for the lighting device inserts into a light socket and receives power for operating the LEDs. A heat transfer body is coupled between the mounting head and the connector and transfer heat generated by the LEDs downward from the mounting head and then radially outward. The mounting head, adhesive, metal pad, and heat transfer body form a heat transfer structure that more effectively removes heat generated by the LEDs. In one embodiment, a dimmer circuit is also provided that allows the LED lighting device to operate with conventional dimmer switches.
