WALL WASH LIGHTING SYSTEM
First Claim
1. An illumination system for illuminating a surface, comprising:
- an optical source for generating light;
an asymmetric optic device for generating output light by total internal reflection (TIR) of the light from the optical source, the asymmetric optic device having an axis, intensity of the output light being asymmetric with respect to the axis of the asymmetric optic device;
a diffuser receiving and diffusing the output light from the asymmetric optic device to generate diffused light; and
a cover lens receiving the diffused light from the diffuser, the cover lens having an etched portion for scattering a portion of the diffused light to generate an output light pattern, the output light pattern having an intensity profile that is asymmetric with respect to the axis of the asymmetric optic device.

Abstract
An illumination system for illuminating a surface includes an optical source for generating light. An asymmetric optic device generates output light by total internal reflection (TIR) of the light from the optical source, intensity of the output light being asymmetric with respect to an axis of the asymmetric optic device. A diffuser receives and diffuses the output light from the asymmetric optic device to generate diffused light. A cover lens receives the diffused light from the diffuser. The cover lens has an etched portion for scattering a portion of the diffused light to generate an output light pattern, the output light pattern having an intensity profile that is asymmetric with respect to the axis of the asymmetric optic device.
