Abstract: An LED downlight comprises a primary reflector having an upper end and an open lower end, an LED printed circuit board assembly disposed in the upper end of the reflector, an optical assembly positioned beneath the LED printed circuit board assembly, a secondary reflective ring positioned beneath the LED printed circuit board assembly and within the primary reflector housing, the secondary reflector ring supporting the optical assembly and improving light distribution.

Abstract: A luminaire housing designed to be installed to illuminate an illumination area, wherein a light source is oriented within the housing to direct a central axis of emitted light rays away from the illumination area and towards a reflective surface of a stationary reflector. In some embodiments the stationary reflector is oriented and contoured to reflect the light rays towards a light spread lens having one end positioned above at least a portion of a reflector lip and angled into the housing with respect to a light passageway. Optionally, the luminaire housing may be a recessed luminaire housing.
