Abstract
A luminaire having an array of light emitting diodes on a circuit board, and a generally planar lens element adjacent each of the LEDs, wherein each lens element has a plurality of concentric ridges projecting from a surface of the lens member to define Fresnel facets for redirecting light emitted from the corresponding LED, providing more uniform light distribution in a compact configuration.
