Abstract
Light reflectors and flood lighting systems for illumination and lighting. Each light reflector may include a housing having a plurality of facets, each of the plurality of facets having a shape that is a portion of separate ellipses sharing a common focus. First and second surfaces are defined by first and second planes intersecting along a line within a volume of the body. A light source is positioned near the first surface, at the common focus, and is angularly oriented thereto such that light emitted by the light source is directed into the housing, reflected by at least one of the plurality of facets, and exits the light reflector out of either the first plane or the second plane. The body of the light reflector may include a free-form surface that is generated as the best fit to the plurality of facets.
Claims23
A light reflector for use with a light source, comprising:
- a housing having a body with a plurality of facets, each of the plurality of facets having a shape that is a portion of one of a plurality of ellipses sharing a common focus, and first and second surfaces formed by first and second planes intersecting along a line within a volume of the body,
- wherein the housing is arranged relative to the light source so that the light source is positioned near the first surface and at the common focus, and the housing is angularly oriented relative to the light source such that a majority of light emitted by the light source is directed into the housing, reflected by at least one of the plurality of facets, and exits the light reflector out of either the first surface or the second surface.
A flood lighting system for illuminating a target surface, the flood lighting system comprising:
- a plurality of light sources;
- and
- a plurality of light reflectors, each of the plurality of light reflectors comprising a housing having a body with a plurality of facets, each of the plurality of facets having a shape that is a portion of one of a plurality of ellipses sharing a common focus, and first and second surfaces formed by first and second planes intersecting along a line within a volume of the body,
- wherein one of the plurality of light sources is positioned near the first surface, at the common focus, and is angularly oriented relative to the respective housing such that a majority of light emitted by the light source is directed into the respective housing, reflected by at least one of the plurality of facets, and exits the light reflector out of one of the first or second surfaces,
- wherein the flood lighting system is mounted at a distance from the target surface.
