  • Patent number: 10699606
    Abstract: An illuminated sign comprises a source of blue light; a quantum dot-containing film that produces green light when illuminated by the source of blue light; and, a patterned blue cutoff filter in optical communication with the quantum dot-containing film configured to allow a mixture of excess blue light from the source of blue light and green light from the quantum dot-containing film to pass through the pattern. The mixture of blue light and green light produces a pseudo white light. The illuminated sign may thus comprise pseudo white letters and/or graphics on a luminous green background.

  • Patent number: 10677420
    Abstract: Optical components for lighting devices and lighting devices including such components are described. In some embodiments the optical components are in the form of a lens that alter the distribution of light produced by a lighting fixture. In some embodiments, the lenses are in the form of a downlight to wallwash lens which, when placed in a downlight fixture, convert the light distribution to that of a wallwash fixture, e.g., causing the downlight to produce an off-axis light distribution, without changing the fixture. The lens includes a body with a light source facing side and an opposite room facing side having two optically active regions, each including structures that redirect a portion of light received through the light source facing side and incident thereon. The first region includes structures that redirect, via refraction, and the second region includes structures that redirect, in part via total internal reflection.
