Some embodiments include a substantial amount of glare and spill light control. An apparatus can include a lamp and fixture with a visor length that is shorter than most conventional spill and glare control visors. The visor allows a controlled, relatively small percentage of direct light from the fixture for a desired or needed level of aerial illumination, but efficiently directs other light to the target. Optionally, a reflective plate is positioned inside the visor to reflect a small percentage of light from the fixture upwardly for up-light. Another embodiment can shift a fraction of light in direction(s) different than the main light output of the fixture.

    Abstract: A flash apparatus and related systems and methods of use are disclosed herein. The apparatus includes a housing having a generally concave reflector, and a light source disposed within the reflector. A handle can be engaged with the housing and/or the light source to facilitate manual positioning and repositioning of the light source relative to a photographic apparatus remote from the housing and/or an object to be photographed. A synchronization device is in communication with the light source and the photographic apparatus for causing the light source to emit a flash of light when the photographic device is actuated. A modifier can also be engaged with the reflector for modifying the emitted flash of light. In a portable system, various interchangeable reflectors, modifiers, and light sources can be provided. Power sources for the light sources and a stand engageable with the handle can also be included.

  • Patent number: 7942560
    Abstract: An LED light source produces a narrow beam of light having a linear field of illumination, which is substantially uniform across the linear field. The light source comprises at least one light emitting diode (LED) and preferably a plurality of LEDs, an optical element for the efficient collection of energy radiating from the LED or LEDs, and an optical element for distributing the collected energy into the linear field of illumination. The apparatus also includes a device or heat sink for thermal management. One or more electronic control circuits are coupled to the LED or LEDs to variably and selectively control them. When a plurality of LEDs are used, the colors produced by the LEDs may different so that the light source is collectively controllable to provide a range of optically mixed colors.

    Abstract: A light guide illumination device is provided. The light guide illumination device includes a light guide shade configured with a spherical shape. The light guide shade includes a light inputting aperture and a light outputting aperture. The light inputting aperture is adapted for receiving a light emitting unit therein. The light emitting unit is adapted for emitting a light therefrom. The light guide shade has an inner spherical surface serving as a light reflecting surface. The light reflecting surface is adapted for reflecting the light for one or more times and outputting the reflected light out from the light outputting aperture. The outputted light is then projected from the light outputting aperture to the ambient space.
