Abstract: A lighting subassembly and components are provided which increase light output and uniformity of brightness and color by use of an optical element that functions simultaneously as an outcoupling TIR light guide and a direct throughput lens. It provides typical benefits of an edgelit light guide design including shallow depth, extended emitting area, and off axis light distributions such as batwing distributions particularly useful in downlighting and other lighting applications. Additionally, area 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.

Abstract: The present disclosure provides an optical arrangement that provides, when in operation, more uniform angular light distribution emissions into an environment. Furthermore, the present disclosure seeks to provide a lighting assembly employing the optical arrangement to provide, when in operation, more uniform angular light distribution emissions into an environment. The present disclosure seeks to provide a solution to a problem of non-uniform angular distribution of light leading to visual discomfort, spatial discontinuity in output light distribution, and non-availability of optical arrangements that enhance optical properties of light emissions and smooth t light emissions. Furthermore, the present disclosure seeks to provide a solution to a problem of, for example, wastage of electrical energy due to improper lighting emissions into an environment.

Abstract: Disclosed is an optical assembly for providing different adjustable light distribution patterns in an environment. The lighting assembly comprises at least one optical element and two or more light source channels each comprising one or more light sources, each light source channel being both physically separated and electrically adjustable in order to control light input into the optical element and subsequently adjust the light distribution output of the optical assembly.
