  • Patent number: 5917291
    Abstract: An electrodeless fluorescent reflector lamp includes a housing arrangement having a threaded screw base for receiving line power and a lamp envelope mounted on the housing arrangement. A ballast circuit is disposed within the housing arrangement and is effective for converting line power into an RF signal which excites a fill contained within the lamp envelope to a discharge state thereby resulting in the production of visible light. The lamp envelope is constructed having an upper curved face portion and a lower tapered portion which extends partly within the housing. A reflective coating is applied to the lower tapered portion of the lamp envelope. A phosphor coating distribution is applied to the interior surface of the lamp envelope in a manner so as to maximize the light output from the reflector lamp.
