  • Patent number: 9004727
    Abstract: A reflector device for a light source device having a light emitter, wherein the reflector device includes first and second reflectors. The first reflector has a first reflector surface adapted to produce a first light beam and the second reflector has a second reflector surface different from the first reflector surface and which is adapted to produce a second light beam different than the first light beam. The second reflector is adapted to be removably coupled to the first reflector such that both reflectors are coupled to the light source device at the same time. This allows a user to change a beam pattern of the light source between a first, default, beam pattern and a second beam pattern by interchanging the second reflector on the light source.

  • Publication number: 20150092420
    Abstract: An optical system comprising a non-specular ceramic reflector surrounding one or more electrode-less bulbs containing a fill that forms a light-emitting plasma when excited with radio frequency, to be used in a fixture for illuminating subjects, for the purpose of high output lighting, such as lighting for image capture, horticulture, stadium, port, roadway, construction and area lighting. This ceramic reflector generates a uniform lambertian reflection specifically evening out the light emission from the electrode-less bulb producing a uniform beam of light with a spread between about 1 to about 300 degrees. This ceramic reflector greatly increases the amount of light falling on a given subject in comparison to the fixture without said reflector system.
