Abstract
A low-profile lighting system includes an asymmetric area lens having a 'batwing' configuration that receives light from at least one light-emitting diode (LED) that emits light having a Lambertian light distribution pattern. The asymmetric lens refracts the light to generate a modified light distribution pattern having light distributed in a selected range of angles. A first portion of the output surface of the asymmetric lens refracts light angularly away from a reference plane. A second portion of the output surface of the symmetric lens refracts light angularly toward the reference plane. The refracted light from the asymmetric lens is provided to a dispersion lens. The dispersion lens produces a dispersed light distribution pattern that illuminates an illumination area. In certain embodiments, the lens has a profile formed by an outer curve having the general shape of an Archimedean spiral or an involute curve.
