Abstract:
A wall wash recessed light fixture has a light engine assembly has an aperture, an LED module operable to emit light through the aperture, a lens disposed between the LED module and the aperture, and a reflector disposed between the LED module and the lens. The LED module has an optical axis passing through the aperture and substantially parallel to a longitudinal axis (Z). The lens has a first side forming a plano-convex lens with a convex surface facing the LED module and has a second side with a Fresnel lens surface facing the aperture, and the lens is aligned at an oblique angle Θ1 relative to the optical axis of the LED module. A diffuser is disposed between the lens and the aperture. The plano-convex lens has a principal axis aligned at the oblique angle Θ1 relative to the optical axis of the LED module.
