“LED Lighting Fixture with a Light Emitting Waveguide Resembling a Lamp Shade” & "Hollow Light Guide Luminaire"

IPApproach LLC is pleased to present the attached exclusive patents for sale LED lighting fixture with a light emitting waveguide resembling a lamp shadeand “Hollow light guide luminaire” which includes U.S. Granted Patents US 9,829,618  B2 and US 10,508,789 B2 assigned to Loom Inc. 

The patent US 9,829,618  B2, relates to a lighting waveguide and its assembly in a LED lighting fixture.

The disclosed technology provides the following  advantages:

  • The invention provides light along long distances by way of a fiber optic cable, illuminating a back-lit advertisement by means of an edge-lit panel behind the advertisement, or providing illumination as a lighting fixture.
  • Perturbation on the major surface of the waveguide enables light to extract from the waveguide, and provides usable illumination.
  • Grooves on the supporting frame of the light fixture match the beads on the waveguide and, when assembled, the beads mate within the said grooves, retaining the waveguide to the supporting frame thus preventing the waveguide from siding out of the light fixture when in use.

The patent US 10,508,789 B2, relates to a hollow light guide luminaire where a light source conveys light through a light ingress surface of a nominally hollow light guide with a narrow portion and a wide portion.

The technology disclosed provides the following  advantages:

  • Extractors, in the form of perturbations of a surface or matrix of a light guide, function to allow light to exit the light guide.
  • Clear acrylic (PMMA) and glass are common materials for light guides due to their optical clarity, which enables the high transmittance of light and minimizes the absorption of light, and ability to be fashioned with glossy surfaces that facilitates TIR.
  • The invention provides an effective conductor and efficient emitter of light, with minimal losses.
  • Light guides in the patent have the benefit of transporting light from a light source and transmitting this light over a larger surface area to reduce the perceived intensity of light and associated glare that would be observable from a relatively small emitting surface of the light source, without any significant losses of actual flux.
  • The invention is capable of meeting the recommendations of RP-1, by providing an architecture of the extractors that directs light to the appropriate angles with the appropriate intensities.
