US Patent 11236887 Optical structures for light emitting diodes (LEDs)

A light system includes a substrate, one or more light emitting diodes (LEDs) coupled to the substrate, and an optical distribution plate positioned proximate the substrate. The optical distribution plate includes one or more optical structures each corresponding to the one or more LEDs. The one or more optical structures include a first surface that focuses LED light from the corresponding LED in a first orientation, and an opposite second surface that distributes LED light from the LED in a second orientation. The second orientation being substantially orthogonal to the first orientation.
