  • Lamp having a secondary halide that improves luminous efficiency
    Patent number: 9171712
    Abstract: A lamp to produce white light includes an envelope; and a composition disposed in the envelope and including an initiator; a primary halide; and a secondary halide, wherein the primary halide, in a presence of the secondary halide, has a vapor pressure that is greater than a vapor pressure in an absence of the secondary halide, and the composition is configured to emit white light in a presence of an electrical discharge in the envelope.
    Type: Grant
    Filed: July 5, 2014
    Date of Patent: October 27, 2015
    Assignee: NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY
    Inventors: John J Curry, Walter P Lapatovich, Edgar G Estupinan

  • Metal halide lamps with fast run-up and methods of operating the same
    Patent number: 8710742
    Abstract: The present disclosure describes metal halide lamps having a discharge vessel, a discharge space, and at least one electrode extending into the discharge vessel in a sealed fashion so as to be in contact with the discharge space. A fill gas, at least one fill material, and optionally at least one volatile material are present in the discharge space. In some cases, the lamps can exhibit at least one of reduced run-up time, increased initial light output, and long life, while remaining useful for general lighting applications. Also described are methods for operating such metal halide lamps.
