    • 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.
    • 本公开提供了一种包括TIR母体透镜和次级输出透镜的光学系统,优选地用于从LED轨道照明系统有效地分配光。 本公开的光学系统被配置为使用相同的TIR透镜从透镜组件产生变化的光束角度。 优选地,通过在单个TIR透镜中改变次级输出透镜的尺寸和焦距,光学系统可以产生各种光束角度,包括但不限于Spot(“SP”),Narrow Flood(“NFL” “),Flood(”FL“)或Wide Flood(”WFL“)光束角度。
