Abstract
A ceiling-mounted luminaire having a bent lens that has a horizontal portion for directing light downward, and a bent or diagonal portion for directing diagonally light toward an adjacent wall. The luminaire improves the flooding of light onto the wall. An auxiliary reflector plate can be inserted within the main reflector to direct more of the source light toward the diagonal portion of the lens to improve the wall lighting.
Claims8
A ceiling-mounted luminaire for directing light at the wall, comprising:
- a) a support structure configured for mounting into a ceiling adjacent to the wall;
- b) a reflector secured to the support structure, having a reflective inner surface and an open end extending toward an opening in the ceiling;
- c) a powered light source disposed within the interior of the reflector;
- and
- d) a lens positioned proximate the open end of the reflector for refracting the light passing out of the open end of the reflector;
- wherein the lens comprises a horizontal portion for refracting a portion of the light perpendicularly downward from the ceiling, and a diagonal portion for refracting a portion of the light diagonally toward the wall.
A bent lens for use in a luminaire, comprising a first planar semi-circular portion having a surface comprising a pattern of prisms, and a second planar semi-elliptical portion having a surface comprising a pattern of prisms, the semi-elliptical portion being oriented at an angle from the first planar portion, wherein a source of light passing through the lens is directed in a first direction perpendicular to the first planar portion, and in a second direction perpendicular to the second planar portion and diagonally downward from the first direction.
