  • Color temperature tunable LED-based lamp module
    Patent number: 9222628
    Abstract: A light mixing and folding lamp includes an LED assembly with two or more LED chips that direct light into the ingress end of a light mixing rod. The light mixing rod is positioned to pass through an aperture in a concave second reflecting element, and mixed light emerges from the egress end of the light mixing rod, where it is directed toward a first reflecting element positioned near a focal point of the second reflecting element. The first reflecting element reflects mixed light emerging from the egress end of the light mixing rod, folding the mixed light back toward a concave reflecting surface of the second reflecting element. The second reflecting element reflects light from the first reflecting element forward, where the light emerges from the lamp directed toward a subject to be illuminated.

  • LED LIGHT SOURCE FOR HAZARDOUS AREA LIGHTING
    Publication number: 20110194280
    Abstract: An LED light source is disclosed that is configured to be retrofit to an existing lamp fixture. The existing lamp fixture is of the type including a ballast housing for providing electrical power. The retrofit assembly includes a central support connectable to the ballast housing. A circuit board is mounted to the support. The circuit board includes one or more LEDs. A dome is mounted to the support and covers the LEDs. A circumferential heat sink is mounted around the support and extends radially beyond the ballast housing to carry heat directly away from the circuit board and support.
