  • Optical waveguide and luminaire incorporating same
    Patent number: 10436969
    Abstract: An optical waveguide includes a body of optically transmissive material having a width substantially greater than an overall thickness thereof. The body of material has a first side, a second side opposite the first side, and a plurality of interior bores extending between the first and second sides each adapted to receive a light emitting diode. Extraction features are disposed on the second side and the extraction features direct light out of at least the first side and at least one extraction feature forms a taper disposed at an outer portion of the body.
    Type: Grant
    Filed: March 15, 2013
    Date of Patent: October 8, 2019
    Assignee: Ideal Industries Lighting LLC
    Inventors: Zongjie Yuan, Kurt S. Wilcox, Eric J. Tarsa, Fabian Jean-Daniel Rol, James Ibbetson, Bernd P. Keller, Nicholas W. Medendorp, Jr.
  • Optical waveguide and lamp including same
    Patent number: 10408986
    Abstract: An optical waveguide includes a body of optically transmissive material having a width substantially greater than an overall thickness thereof and including a first side, a second side opposite the first side, a central bore extending between the first and second sides and adapted to receive a light emitting diode, and extraction features on the second side. A light diverter extends into the central bore for diverting light into and generally along the width of the body of material. The extraction features direct light out of the first side and wherein at least one extraction feature has an extraction surface dimension transverse to the thickness that is between about 5% and about 75% the overall thickness of the body of material.
