  • 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.

  • Patent number: 8992052
    Abstract: An optical element for a lamp or lighting apparatus having at least one light emitting diode (LED) as a light source is provided. The optical element is positioned proximate to the LED and receives light rays therefrom. In turn, the optical element distributes the substantially unidirectional light output from the LED into an omnidirectional output with a controlled variance in light intensity at different directions about the LED. A diffuser can also be used around the optical element and LED to provide further distribution of the light rays by e.g., light scattering.

  • Patent number: 8979321
    Abstract: A light guide (201) including a transparent element is presented. The transparent element includes an optical diverter section (204) including one or more reflective surfaces (205) forming walls of a notch (206) extending into the diverter section, where the reflective surfaces provide total reflections for directing light into directions lateral with respect to an arrival direction of the light. The transparent element includes an optical channel section (208) for receiving the light from a light source and for directing the light to the optical diverter section. The optical channel section includes a side surface (209) shaped to provide total reflections for directing light to the optical diverter section. The optical channel section makes it possible to place the light source a distance apart from the optical diverter section and also to prevent or at least to reduce direct propagation of light from the light source to the lateral directions.
