Abstract
A catadioptric lens assembly is disclosed for use with various light emitting sources. The lens assembly includes an upper section and a lower section, right and left portions thereof being symmetrically disposed about a center vertical optical axis defining a plane normal to and perpendicular to a longitudinal axis. The upper section includes two lens lobes with surfaces exhibiting a positively curved elliptical, circular or parabolic shape, being bilaterally symmetric about the vertical optical axis. The lower section includes a single lens lobe with a surface exhibiting a negatively curved spherical shape, bilaterally symmetric about the vertical optical axis, connecting to symmetric linear transition regions on both sides of the lower section and transitioning to edge support regions shared by the upper section of the lens assembly. Co-extrusion or selected surface treatment to form a top, bottom, or dual optical layer integral to surfaces of the catadioptric main lens enables improved dispersal of incident light resulting in more uniform illumination.
