  • LED lighting systems for product display cases
    Patent number: 7954979
    Abstract: A lighting assembly for illuminating a display case includes an LED that illuminates items placed in the display case. The lighting assembly can attach to a door, a door frame, or another structure of the display case.
    Type: Grant
    Filed: May 25, 2005
    Date of Patent: June 7, 2011
    Assignee: GE Lighting Solutions, LLC
    Inventors: Mathew Sommers, Mark Mayer, Chris Bohler, James Petroski, Melissa Wesorick
  • Method and apparatus for tri-color rail signal system with control
    Patent number: 7385481
    Abstract: A signaling control device apparatus (10) comprises at least one LED (20) having a light emitting surface (18). A sensor (24) is set to detect an external light load (16) directed to the light emitting surface (18) and generate a control signal indicative of a presence of the light load (16). An electrical control system (14) detects the control signal indicative of the light load (16) and sources an elevated current to the LED (20) while the light load (16) is present. The elevated current increases the contrast ratio making the signal perceivable by the users as being in a particular state.

  • LED with series-connected monolithically integrated mesas
    Patent number: 7285801
    Abstract: A light emitting semiconductor device die (10, 110, 210, 310) includes an electrically insulating substrate (12, 112). First and second spatially separated electrodes (60, 62, 260, 262, 360, 362) are disposed on the electrically insulating substrate. The first and second electrodes define an electrical current flow direction directed from the first electrode to the second electrode. A plurality of light emitting diode mesas (30, 130, 130?, 230, 330) are disposed on the substrate between the first and second spatially separated electrodes. Electrical series interconnections (50, 150, 250, 350) are disposed on the substrate between neighboring light emitting diode mesas. Each series interconnection carries electrical current flow between the neighboring mesas in the electrical current flow direction.
