Abstract
A lighting assembly includes LEDs arranged at a surface of a substrate, and optical elements proximate the LEDs such that each optical element overlies a single LED and each LED underlies a single optical element. Each optical element includes a first part, a second part intersecting the first part such that a normal to surface of the second part intersects a normal to the surface of the first part, and a third part extending away from the associated LED beyond a region between the first and second part. The LEDs and optical elements are configured such that light from each LED is directed towards an area to be illuminated in a uniform pattern covering the area.
