Patent number: 11035527Abstract: A light fixture with a troffer design. One light fixture includes light guide plates that extend above a back pan of the housing. LED assemblies are connected to light guide plates and direct light into the light guide plates through one of the outer edges. Each of the light guide plates receive the light through the outer edge and directs the light outward from the outer surface. Another light fixture includes a back pan, first and second light panels that are positioned above and spaced away from the back pan. Pixels are mounted on the outer surface of the light panels with each of the pixels configured to emit light.Type: GrantFiled: July 23, 2020Date of Patent: June 15, 2021Assignee: IDEAL Industries Lighting LLCInventors: Jin Hong Lim, Mark Boomgaarden, Randall Levy Bernard

Patent number: 11029008Abstract: A lighting fixture includes a housing, a light source, and a diffuser. The light source is mounted in the housing. The diffuser is also mounted in the housing such that light emitted from the light source is provided through the diffuser towards an area of interest. The diffuser is configured such that a color of the diffuser is based on one or more characteristics of the light emitted from the light source. Providing the diffuser such that the color thereof is based on one or more characteristics of the light emitted from the light source allows the aesthetic appearance of the lighting fixture to be changed. Further, it allows the lighting fixture to better simulate outdoor environments. Finally, it allows the lighting fixture to convey information to individuals near the lighting fixture without being disruptive.Type: GrantFiled: October 29, 2019Date of Patent: June 8, 2021Assignee: IDEAL Industries Lighting LLCInventor: Mark Boomgaarden

Patent number: 11032885Abstract: A single solid state luminaire product is field-configurable to a plurality of discrete coordinated color temperature (CCT) and/or maximum luminosity settings. A field-actuated control circuit may control a current ratio control circuit, which directs drive current from a power supply to selected ones, or in selected ratios to multiple ones, of heterogeneous LED strings. Additionally or alternatively the control circuit may control the power supply, to select an overall maximum level of drive current, which determines the maximum luminosity of the luminaire. Inputs for CCT and/or maximum luminosity are input to the field-actuated control circuit prior to the luminaire being removed from its product packaging. Embodiments allow a distributor to order and stock a large inventory of substantially identical luminaires from the manufacturer, yet still offer customers a variety of different CCT and/or maximum luminosity products.Type: GrantFiled: April 17, 2020Date of Patent: June 8, 2021Assignee: IDEAL Industries Lighting LLCInventors: Jen Huang, P.
