  • Light valve surface image and light beam projector
    Patent number: 11971619
    Abstract: A lighting system and method controls light to prioritize different elements of the beam of light that is output by a fixture. The LCD surface acts as a color occlusion filter that provides pixel level control of the beam of light transmitted by this layer. Internally an LED source is projected perpendicular to concave type reflector which can be moved on one axis and thus zoom to either widen or narrow the light emitted forward as a beam of light. The system also includes certain cooling features.
    Type: Grant
    Filed: February 9, 2022
    Date of Patent: April 30, 2024
    Assignee: Sandbox Light Engineering Corporation
    Inventors: Christopher D. Ewington, Matthew E. Ward, Jeremy Hochman
