Abstract
The present disclosure provides an optical system including a TIR mother lens and a secondary output lens, preferably for efficiently distributing light out of an LED track lighting system. The optical system of the present disclosure is configured to create variant beam angles from a lens assembly using the same TIR lens. Preferably, by altering the dimensions and focal lengths of the secondary output lens in a single TIR lens, the optical system can create a variety of beam angles, including, but not limited to, Spot ('SP'), Narrow Flood ('NFL'), Flood (“FL”), or Wide Flood (“WFL”) beam angles.
