  • Patent number: 10036517
    Abstract: A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

  • Patent number: 9937879
    Abstract: The present disclosure relates to the formation of high contrast, wavelength independent retroreflective sheeting made by including a light scattering material on at least a portion of the retroreflective sheeting. The light scattering material reduces the brightness of the retroreflective sheeting without substantially changing the appearance of the retroreflective sheeting when viewed under scattered light.

  • Patent number: 9765950
    Abstract: Generally, the present disclosure provides for a light duct sensor that can monitor an average light flux through light duct useful for architectural lighting. The present disclosure provides for a system that allows a minimally obtrusive sampling of the light in a duct. It samples a small fraction of a cross sectional area of a light duct that is distributed across potentially the entire cross sectional area, without creating a significant disturbance to the light.

  • Patent number: 9279548
    Abstract: A light collimating horn assembly having two horns, one contained within the other. The horns have reflective surfaces facing each other. A light source, such as a ring of light emitting diodes, is located between the reflective surfaces of the horns. The horns at least partially collimate light from the light source transmitted between the reflective surfaces and exiting from the horns. The horns can be configured to provide controlled collimation in order to substantially collimate light for a spot light or partially but not substantially collimate light for a flood light.
