  • APPARATUS FOR CONTROLLING THE RE-DISTRIBUTION OF LIGHT EMITTED FROM A LIGHT-EMITTING DIODE
    Publication number: 20160215954
    Abstract: A system for re-distributing light emitted from a light source using an optical element is described. The optical element is manufactured using a bulk matrix material, and diffusing particles and/or scattering particles are embedded within the bulk material. The optical element is coupled to the light source to capture emitted light and redistribute the light in a desired angular distribution pattern depending on the ratio of total weight of diffusing particles to total weight of scattering particles.
    Type: Application
    Filed: March 18, 2016
    Publication date: July 28, 2016
    Inventors: John R. Green, Stephen H. Humphrey, Andrew B. Leslie, Timothy R. Robinson
