Planar mechanical actuation system for adjustable luminaires

Patent Gladden, Christopher; Chub, Victor; Kozodoy, Peter

A mechanical actuation system for a light fixture that allows for translation of an array of optics relative to an array of light sources in a defined plane. The system can prevent undesired movement such as rotation or out-of-plane motion. A simple and intuitive user interface enables a user to point a resulting light beam in a desired direction without requiring an understanding of the internal mechanical system. The user interface may include a manually manipulated touch point such as a joystick, knob, or other interface.

Luminaire with controllable light emission

Patent Girotto, Claudio; Tarsa, Eric; Snell, Nathan Ray; ...

A luminaire includes a first waveguide having a first primary light emitting surface directed in a first direction and a first secondary light emitting surface directed in a second direction. A second waveguide having a second primary light emitting surface directed in the second direction and a second secondary light emitting surface directed in the first direction. A first plurality of LEDs are optically coupled to the first waveguide and a second plurality of LEDs are optically coupled to the second waveguide. The first and second waveguides are independently operable. The first and second plurality of LEDs may comprise LEDmore » « less

Optimizing multichannel luminaire control using a color efficient matrix

Patent Hu, Jia; Smith, Meg; Rizzo, Patricia

The described embodiments relate to multichannel luminaires (102, 212, 404) that employ a color coefficient matrix (CCM) that can be used to adjust an operation of the multichannel luminaires according to their contribution of light to an area (112, 402). The CCM can be generated based on images captured within the area and/or a software simulation that approximates the contribution of light from the multichannel luminaires to the area. Once the CCM has been generated, the CCM can be used to compensate control signals to each multichannel luminaire in order to provide more accurate color rendering and uniform light distribution.more » « less
