Patents by Inventor Robert Michael Ezell

Robert Michael Ezell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11624495
    Abstract: In one or more embodiments, a luminaire includes a housing, a light source coupled with the housing, an optical sheet coupled with the housing, and a film stabilizer coupled with the housing. The optical sheet includes a first surface and an opposing second surface that are both disposed substantially horizontally when the luminaire is in an installed orientation. The first surface is disposed facing the light source, so that when the light source emits light, the light passes first through the first surface and subsequently through the second surface. The film stabilizer includes a third surface and an opposing fourth surface. The film stabilizer is disposed with the third surface adjacent to the second surface of the optical sheet, and provides mechanical support for the optical sheet.

  • Patent number: 11499683
    Abstract: A luminaire includes a housing that defines a light output aperture, a backlight apparatus that emits light toward the light output aperture, and an optical sheet of light transmissive material. The optical sheet is adjacent the backlight apparatus and modifies the light before it leaves the light output aperture. The optical sheet forms a first surface and an opposite second surface. At least one of the first surface or the second surface of the optical sheet includes a first spatial region that includes elliptical diffusers oriented predominantly in a first direction, a second spatial region that includes elliptical diffusers oriented predominantly in a second direction that is different from the first direction, and a third spatial region that includes at least one type of optical microstructure selected from the group consisting of Fresnel lenses, v-groove lenses, v-cut lenses, pyramidal lenses, lenticular lenses, donut lenses and conical diffusers.
