Patent ID: 10274159

Abstract:
Lenses and methods for directing light toward a side of light fixture, and methods for manufacturing the same, are disclosed. Embodiments include lenses with an optical axis and a first (e.g., upper) portion that is rotationally symmetric about the optical axis and a second (e.g., lower) portion that is rotationally asymmetric. The first/upper portion can include a cavity that receives an LED and directs light toward the second/lower portion. The asymmetric side can include a convex surface where the light exits the lens, the convex surface extending across the optical axis. Additional embodiments include a planar surface adjacent the convex surface, where the height of the lens decreases along the portion of the convex surface near the planar surface and along the planar surface as the distance from the optical axis increases. In further embodiments, the maximum height of the lens occurs between two horizontal sides of the lens.
