Abstract
A downlight reflector assembly for a light-emitting diode (LED) light source includes a kicker reflector and an upper scoop. The kicker reflector has a reflector wall extending between a small top opening and a large bottom opening along a transverse axis. The reflector wall has an internal surface with an illuminated area and a non-illuminated area. The upper scoop is mounted in the small top opening of the kicker reflector and has a reflective multi-faceted surface with a concave curvature relative to the LED light source. The upper scoop extends from the top opening in part along the transverse axis and covering a portion of the top opening. The multi-faceted surface faces both of the illuminated area of the kicker reflector and the top opening for reflecting light rays received through the top opening towards the illuminated area.
