Patent number: 10948162Abstract: An optic for aisle lighting includes a portion of an optical material defined by a length and a cross-sectional profile. The cross-sectional profile is characterized by a cavity within the optical material, two upwardly-facing surfaces of the optical material on opposite sides of the cavity from one another, and downwardly-facing surfaces of the optical material. The cavity is bounded by an upward facing aperture, and at least three faces of the optical material that meet at interior angles. Light received through the upward facing aperture is separated at the interior angles, and refracted by the faces of the optical material, into separate light beams equal in number to the faces. The two upwardly-facing surfaces internally reflect the separate light beams downwardly. The downwardly-facing surfaces intercept respective portions of the separate light beams, and refract the portions as they exit the optic.Type: GrantFiled: May 6, 2019Date of Patent: March 16, 2021Assignee: ABL IP Holding LLCInventors: Jie Chen, Craig Eugene Marquardt

Patent number: 10906259Abstract: Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.Type: GrantFiled: February 8, 2019Date of Patent: February 2, 2021Assignee: ABL IP Holding LLCInventors: Craig Eugene Marquardt, Forrest Starnes McCanless, Jie Chen, John Bryan Harvey, Yinan Wu, Daniel Aaron Weiss

Patent number: 10895364Abstract: A light fixture for lighting a surface includes a housing, a plurality of light sources, and a molded optic through which light from the light sources is directed. The molded optic further includes a plurality of concave aspheric optical surfaces in a first side of the molded optic, each of the concave aspheric optical surfaces partially enclosing one or more of the plurality of light sources, wherein the aspheric concave optical surfaces receive light directly from the respective light sources, and a plurality of convex aspheric optical surfaces disposed respectively opposite the plurality of concave aspheric optical surfaces on a second side of the molded optic, opposite the first side. The light sources and the aspheric optical surfaces cooperate to direct light onto the surface in an illumination field that is generally rectangular.Type: GrantFiled: November 11, 2019Date of Patent: January 19, 2021Assignee: ABL IP Holding LLCInventors: Jie Chen, Craig Eugene Marquardt

Patent number: 10890313Abstract: Optics over a light source, such as, but not limited to, an LED on a circuit board. The optic does not entirely encapsulate the LED but rather includes an inner surface such that an air gap exists between the optic and the LED. The optic may include a lens and may conform to the shape of the circuit board.Type: GrantFiled: February 25, 2020Date of Patent: January 12, 2021Assignee: ABL IP Holding LLCInventors: Craig Eugene Marquardt, Jie Chen, Daniel Aaron Weiss

Patent number: 10571095Abstract: Optics for asymmetrically redirecting light from one or more light engines include a dome optic, and first and second reflecting surfaces. The dome optic refracts light emitted by the light engines. The first reflecting surface redirects at least a portion of the light that is initially emitted toward a backward horizontal direction, toward the forward horizontal direction. The first reflecting surface extends substantially vertically and along a transverse horizontal direction, proximate to and behind the dome optic, and has a height greater than or equal to a height of the dome optic. The second reflecting surface reflects downwardly at least a portion of the refracted light that is initially emitted in the forward horizontal direction. The second reflecting surface is proximate to the dome optic and forward of the dome optic, and forms an angle of 45 degrees or more with respect to vertical.Type: GrantFiled: January 18, 2019Date of Patent: February 25, 2020Assignee: ABL IP Holding LLCInventors: Jie Chen, Yinan Wu, John Bryan Harvey, Craig Eugene Marquardt, Charles H.
