Abstract
A semi-recessed downlight wall wash canopy luminaire includes a plaster frame, a lamp socket, a lamp, a downlight reflector, a wall wash reflector, and a trim piece. The plaster frame mounts behind the canopy or ceiling sheeting for supporting the components of the luminaire in relation to an opening in the sheeting. The lamp socket holds the lamp above the opening. The downlight and wall wash reflectors are positioned in surrounding relation to the lamp. The wall wash reflector has a bottom portion which extends below the plaster frame and the sheeting for reflecting light toward a wall at high angles. A trim piece extends downward from the plaster frame and below the bottom portion of the wall wash reflector providing a finished appearance. The trim piece has a bottom opening and a side window, which may be covered by refractive lenses.
