  • Modular optic for changing light emitting surface
    Patent number: 9441819
    Abstract: An LES is a surface from which light emanates from a lighting fixture. The present disclosure relates to a providing a lighting fixture that has an actual light emitting surface (A-LES), which is substantially smaller than the maximum potential LES (M-LES) for the lighting fixture. The M-LES is defined as the theoretical maximum LES for the mounting structure of the lighting fixture, and the A-LES is defined as the actual LES of the lighting fixture, as dictated by the lens or optical structures of the lighting fixture. The A-LES may provide an LES that is not only smaller, but also shaped differently, from the M-LES, to help control the light output of the lighting fixture based on the lighting application.
    Type: Grant
