  • LED luminaire for display cases
    Patent number: 8678616
    Abstract: A lighting luminaire for use in a refrigerated display case includes an LED mounting portion comprising a plurality of light emitting diodes (“LEDs”) mounted thereon, a reflector, and a lens. The LED mounting portion and reflector are sized and arranged to form a reflective cavity for diffusing and directing light from the plurality of LEDs through the lens and out of the luminaire. The LED mounting portion and reflector are either attached to each other as separate components or are integrally formed. The lens is held in place in the luminaire between the LED mounting portion and the reflector or is mounted directly on the LED mounting portion over the plurality of LEDs. The LED mounting portion and/or reflector have a reflective surface for reflecting light emitted by the LEDs. Methods for retrofitting an existing luminaire in a refrigerated display with an LED luminaire are also provided.

  • CHAOTIC APPROACH TO CONTROL OF LIGHTING
    Publication number: 20140055041
    Abstract: At least one controllable source of visible light is configured to illuminate a space to be utilized by one or more occupants. A controller causes the source(s) to emit light in a manner that varies at least one characteristic of visible light emitted into the space over a period of time at least in part in accordance with a chaotic function.

  • Adjustable light distribution system
    Patent number: 8651694
    Abstract: A lighting assembly having a plurality of light sources and a lens matrix having a plurality of lenses. The lens matrix may be positioned relative to the light sources so that each light source resides in a first orientation within one of the lenses and emits a light distribution. Relative translation between the light sources and the lens matrix alters the orientation of the light sources within the lenses, creating a different light distribution. A light source's orientation may change within the same lens, or the light source may translate to a different lens to alter the distribution of its emitted light.

  • LED DRIVER WITH DIAC-BASED SWITCH CONTROL AND DIMMABLE LED DRIVER
    Publication number: 20130342126
    Abstract: An LED driver may use a DIAC oscillator circuit to controls a semiconductor switch in a switching circuit. The DIAC oscillator circuit uses rectified line power and so it does not require a separate power source. An LED driver may uses a zero crossing circuit to provide low level dimming. The zero crossing circuit includes a linear circuit or a constant current circuit that keeps a TRIAC dimmer on and stable during low current levels.

  • Active cooling systems for optics
    Patent number: 8596826
    Abstract: Light engines that include a plurality of light sources each covered with an optic The optic includes a chamber that receives the light source. In one embodiment, tubes connect adjacent light sources. Coolant is introduced into the tubes and circulates into the chamber of each optic, thus removing thermal energy from the chamber. In other embodiments, the light engines include a heat sink provided with channels. Coolant may be introduced into one of the channels, and may then circulate into the chamber of each optic to remove heat generated by the light source from the chamber. The channels provide a fluid path for the coolant to move between the different optics.
