Abstract
Inventive methods and apparatus for providing an open wall wash luminaire designed to allow a small amount of light to go behind the luminaire kick reflector, resulting in the kick reflector being less noticeable by an occupant of the room when light is being provided by the luminaire.
Claims15
A luminaire for providing substantially uniform light distribution along a flat wall surface, the luminaire comprising:
- a light source;
- a housing having an internal reflective surface and an elongated light emitting opening therein in a plane substantially perpendicular to the wall surface to be illuminated;
- the opening having a center region;
- a kick reflector comprising a frontal layer that is reflective on both sides;
- wherein at least part of the kick reflector resides within the housing and is positioned between the internal reflective surface and the center region of the housing such that a distance exists between the internal reflective surface of the housing and the frontal layer along the frontal layer's entire length;
- and,
- wherein in use, light from the light source passes through said distance between the frontal layer and the housing before being emitted from the light emitting opening at a location between the housing and the frontal layer.
A luminaire for providing substantially uniform light distribution along a flat wall surface, the luminaire comprising:
- a light source;
- a housing having an internal reflective surface and an elongated light emitting opening therein in a plane substantially perpendicular to the wall surface to be illuminated;
- the opening having a center region;
- a plurality of kick reflectors, each comprising a frontal layer that is reflective on both sides;
- wherein for each of said kick reflectors:
- at least part of the kick reflector resides within the housing and is positioned between the internal reflective surface and the center region of the housing such that a distance exists between the housing and the frontal layer along the frontal layer's entire length;
- and,
- wherein in use, light from the light source passes through said distance between the frontal layer and the housing before being emitted from the light emitting opening at a location between the housing and the frontal layer.
A method for enabling a luminaire to provide substantially uniform light distribution along a flat wall surface;
- wherein the luminaire comprises a light source, a housing having an internal reflective surface and an elongated light emitting opening therein in a plane substantially perpendicular to the wall surface to be illuminated wherein the opening has a center region, and a kick reflector residing in the housing and comprising a frontal layer that is reflective on both sides;
- the method comprising:
- positioning the kick reflector between the internal reflective surface of the housing and the center region of the housing such that a distance exists between the internal reflective surface of the housing and the frontal layer along the frontal layer's entire length;
- and,
- enabling light from the light source to pass through said distance between the frontal layer and the internal reflective surface of the housing before being emitted from the light emitting opening at a location between the housing and the frontal layer.
