  • Patent number: 11874489
    Abstract: 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.
