Patent number: 12055748Abstract: An optical element with light scattering properties is configured for use in a light fixture or lighting module. When used in combination with a reflector or reflective surface proximate to an output face, the optical element can provide a range of non-Lambertian light distributions in alternative embodiments. The optical element utilizes combinations of dispersed light scattering particles and/or surface features to selectively scatter, disperse and internally reflect light. Using such optical arrangements it is possible to create light distributions with a single or multiple lobes or peak intensities and to control the position and shape of light distributions. The optical element is particularly suitable in low profile edge lit lighting assemblies used in indoor lighting products such as suspended, surface or recessed mounted linear light fixtures, ceiling mounted downlights, cove lights, and light fixtures for wall washing or perimeter lighting.Type: GrantFiled: April 24, 2023Date of Patent: August 6, 2024Assignee: Fusion Optix, Inc.Inventors: Terence Yeo, Timothy Kelly

Patent number: 11874489Abstract: Various light fixtures are provided for mounting within and below suspended grid ceilings incorporating T-bars and ceiling panels. The light fixtures comprise a double or single edgelit planar or wedge shaped optical element that functions simultaneously as an outcoupling TIR light guide and a light scatterer or direct throughput lens. It provides a number of benefits because of its edgelit design including; thin forms and shallow depth, extended emitting area and controlled lighting distributions from one or two light guide faces. Additionally, areas typically dedicated to bezels or edge reflectors can be greatly reduced or eliminated due to decreased hotspotting to provide a fixture face with very high percentage of light emitting area. Embodiments are described for direct, indirect, and direct indirect configurations. The embodiments provide increased light output, uniformity of brightness and color and controlled direct and indirect lighting distributions and with single or dual off axis intensity peaks.Type: GrantFiled: March 11, 2022Date of Patent: January 16, 2024Assignee: Fusion Optix, Inc.Inventors: Terence Yeo, Timothy Kelly
