Abstract
A device for projecting light from a source to illuminate an area, having a lens, including at least two planar lens elements angularly disposed relative to each other. A first reflector is oriented to direct light from the source, substantially parallel to the first element and through said second element at a high angle of incidence which maximizes the passage of light and minimizes the secondary reflection of light from the source.
Claims23
A device for projecting light to illuminate an area comprising:
- a. light source;
- b. lens having at least a first planar element, a second planar element, a third planar element, and a fourth planar element and said first planar element angularly oriented with respect to said second planar element and said third and fourth planar elements angularly oriented with respect to each other and to said first and second planar elements forming a pyramidal shaped lens;
- c. first reflector oriented to reflect light from said source substantially parallel to said first planar element, a definable portion of the reflected light passing below said source and through said second planar element in a first maximum candle power plane from said device to the area to be illuminated;
- d. second reflector oriented to reflect light from said source substantially parallel to said second planar element, a definable portion of the reflected light passing below said source and through said first planar lens element in a second maximum candle power plane from said device to the area to be illuminated.
1 more element
A device for projecting light to illuminate an area comprising:
- a. light source;
- b. lens having at least a first planar element and a second planar element, said first element angularly oriented with respect to said second element;
- c. first upper peripheral reflector oriented to reflect light from the source substantially parallel to said first planar lens element, the reflected light passing above said source and through said second planar lens element in a maximum candle power plane to the area to be illuminated.
