  • LED LIGHTING FIXTURE HAVING MULTIPLE LED CLUSTERS WITH RELATIVE ANGULAR DISPLACEMENT (ROTATION)
    Publication number: 20230288044
    Abstract: A light-emitting diode (LED) lighting fixture includes a substrate and a plurality of LED clusters disposed on the substrate in a plane in which two orthogonal axes defining a two-dimension coordinate system is disposed. At least two of the LED clusters have orientations which are relatively angularly displaced within the two-dimensional coordinate system.

  • Wall wash lighting system
    Patent number: 9291334
    Abstract: An illumination system for illuminating a surface includes an optical source for generating light. An asymmetric optic device generates output light by total internal reflection (TIR) of the light from the optical source, intensity of the output light being asymmetric with respect to an axis of the asymmetric optic device. A diffuser receives and diffuses the output light from the asymmetric optic device to generate diffused light. A cover lens receives the diffused light from the diffuser. The cover lens has an etched portion for scattering a portion of the diffused light to generate an output light pattern, the output light pattern having an intensity profile that is asymmetric with respect to the axis of the asymmetric optic device.
