Patent number: 10197245Abstract: 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: November 9, 2016Date of Patent: February 5, 2019Assignee: ABL IP Holding LLCInventors: Jie Chen, Yinan Wu, John Bryan Harvey, Craig Eugene Marquardt, Charles H.

Publication number: 20190016073Abstract: 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: ApplicationFiled: September 26, 2018Publication date: January 17, 2019Inventors: Craig Eugene Marquardt, Forrest Starnes McCanless, Jie Chen, John Bryan Harvey, Yinan Wu, Daniel Aaron Weiss

Patent number: 9903561Abstract: A luminaire provides an asymmetric light distribution biased toward a forward horizontal direction. The luminaire includes a luminaire housing, light engines, dome optics, and first and second reflecting surfaces. The light engines emit light downwardly, and are in a row substantially orthogonal to the forward direction. Each of the dome optics is substantially similar, and refracts the light emitted by at least one of the light engines. The first reflecting surface reflects at least a first portion of the refracted light toward the forward direction, is proximate and behind each of the dome optics, forms an approximately vertical angle, and has a height greater than or equal to a height of the dome optics. The second reflecting surface is forward of the dome optics, forms an angle of 45 degrees or more with respect to vertical, and reflects downwardly at least a second portion of the refracted light.Type: GrantFiled: November 9, 2016Date of Patent: February 27, 2018Assignee: ABL IP Holding LLCInventors: Jie Chen, Yinan Wu, John Bryan Harvey, Craig Eugene Marquardt, Charles H.

Publication number: 20180045385Abstract: A luminaire includes a housing, a luminous zone coupled with the housing, and one or more transition zones coupled with the housing and disposed adjacent to the luminous zone. The luminous zone provides a first light to an illuminated area, and the one or more transition zones provide a second light to the illuminated area. The first light is harsher than the second light. A method of illuminating an area includes providing a first light to the area from a luminous zone of a luminaire and providing a second light to the area from one or more transition zones disposed adjacent to the luminous zone within the luminaire. The first light is a harsher light than the second light.Type: ApplicationFiled: August 11, 2017Publication date: February 15, 2018Applicant: ABL IP Holding LLCInventors: Yulia Tyukhova, Jon Eric Gibson, John Bryan Harvey, Jie Chen, Craig Eugene Marquardt, Daniel Vincent Sekowski

Patent number: 9587802Abstract: An LED assembly that includes optics and optical arrangements for light emitting diodes (LEDs). In some embodiments, a reflector is provided within a void between the lens and the LED. This reflector can reflect light emitted by the LED in a non-preferred direction back toward the preferred direction. In other embodiments, an optical element is formed or otherwise provided in the lens cavity and shaped so that, when the lens is positioned above the LED, the refractor bends the emitted light in a preferred direction. In some embodiments, both a reflector and optical element are provided in the LED assembly to control the directionality of the emitted light. Such embodiments of the invention can be used to increase the efficiency of an LED by ensuring that generated light is being directed to the target area of choice.Type: GrantFiled: April 22, 2015Date of Patent: March 7, 2017Assignee: ABL IP Holding LLCInventors: Jie Chen, Craig Eugene Marquardt, Daniel Aaron Weiss, Daniel Vincent Sekowski, Yaser S.

Patent number: 9400087Abstract: A shield for a light emitting diode (LED) luminaire includes a frame mountable to the LED luminaire such that the shield is removable therefrom. A plurality of rows of shield surfaces contact the frame and have a first side that faces a row of LEDs located on the LED luminaire and an opposite second side. The first side has a fully or partially reflective surface. The plurality of rows of shield surfaces prevent light from the LEDs from reflecting toward the back of the LED luminaire. The shield may include notches for allowing removal of one or more of the plurality of rows of shield surfaces or a portion thereof from the frame and for customization of light distribution from the LED luminaire. The shield may also be cut lengthwise such that each of the plurality of rows of shield surfaces includes a partial shield surface and shields only a portion of a row of LEDs located on the LED luminaire.Type: GrantFiled: March 12, 2014Date of Patent: July 26, 2016Assignee: ABL IP Holding LLCInventors: Craig Eugene Marquardt, Patrick A.

Patent number: 9335041Abstract: A light fixture includes a door frame, the door frame having at least one frame side and a reflector. The edge of the reflector engages a slot in the frame side, which includes at least one LED, to precisely position the reflector and the at least one LED relative to one another. The at least one frame side may also include a reflective kicker for reflecting light from the at least one LED onto the reflector. The reflector may include a semi-specular optical material, which specularly reflects some of the incoming light from the at least one LED and diffusely reflects other of the incoming LED light. The reflector may be collapsible for ease of transportation and shipping; the at least one frame side precisely positions the reflector and at least one LED during assembly and installation.Type: GrantFiled: March 14, 2013Date of Patent: May 10, 2016Assignee: ABL IP Holding LLCInventors: Craig Eugene Marquardt, Januk Swarup Aggarwal, Xin Zhang, John T.
