  • Stabilized emissive structures and methods of making
    Patent number: 8138675
    Abstract: An emitter is disclosed. The emitter includes a base layer comprising an array of nanocavities on an emission surface of the base layer, wherein facets of the nanocavities are substantially along equivalent crystallographic planes of one or more families of planes having substantially equal surface energies, wherein the equivalent crystallographic planes have surface energies equal to or lower than a surface energy of the crystallographic plane of the emission surface. Methods of making such emitters and radiation sources including such emitters are also disclosed.
    Type: Grant
    Filed: February 27, 2009
    Date of Patent: March 20, 2012
    Assignee: General Electric Company
    Inventors: Andrew David Deal, William Paul Minnear, Gregory Michael Gratson, David Jeffrey Bryan

  • Thermal management of high intensity discharge lamps, coatings and methods
    Patent number: 7728499
    Abstract: Ceramic HID lamps with improved thermal management having an adherent infrared reflective coating layer located on the outer surface of the vessel are described. They include a coating of a nonmetallic material proximate the first and second end portions of the vessel. Such coatings can minimize temperature gradients during lamp operation. Methods for preparing such lamps with improved thermal management are described as well.
