Abstract

An apparatus and method according to which light is provided.

Claims

1. A method for providing light, comprising:

reflecting at least a portion of light from a light source to produce a scallop beam pattern on a surface;

allowing at least another portion of light from the light source to be reflected to produce another beam pattern on the surface; and

merging the scallop beam pattern and the other beam pattern to form a wash beam pattern.

2. The method of claim 1, wherein the wash beam pattern defines a boundary, the boundary defining a substantially continuous curve.

3. The method of claim 2, wherein the substantially continuous curve is substantially free of inflection points.

4. The method of claim 1, wherein the other beam pattern is substantially trapezoidal in shape.

5. A method for providing light, comprising:

reflecting at least a portion of light from a light source to produce a scallop beam pattern on a surface;

allowing at least another portion of light from the light source to be reflected to produce a trapezoidal beam pattern on the surface; and

merging the scallop beam pattern and the trapezoidal beam pattern to form a wash beam pattern, wherein the wash beam pattern defines a boundary, the boundary defining a substantially continuous curve, whereby the substantially continuous curve is substantially free of inflection points.

6. A method for providing light, comprising:

providing a plurality of light sources positioned adjacent a surface;

reflecting at least a portion of light from each light source to produce a plurality of scallop beam patterns on the surface;

reflecting at least another portion of light from each light source to produce a plurality of other beam patterns on the surface; and

merging the plurality of scallop beam patterns and the plurality of other beam patterns to form a plurality of wash beam patterns on the surface.

7. The method of claim 6, wherein each of the wash beam patterns define a boundary, the boundary defining a substantially continuous curve.

8. The method of claim 7, wherein the substantially continuous curve is substantially free of inflection points.

9. The method of claim 6, wherein the plurality of other beam patterns are substantially trapezoidal in shape.

10. The method of claim 6, further comprising:

merging the plurality of wash beam patterns to uniformly light the surface.

11. A method for providing light, comprising:

providing a plurality of light sources adjacent a surface;

reflecting at least a portion of light from each light source to produce a plurality of scallop beam patterns on the surface;

reflecting at least another portion of light from each light source to produce a plurality of trapezoidal beam patterns on the surface;

merging the plurality of scallop beam patterns and the plurality of trapezoidal beam patterns to form a plurality of wash beam patterns on the surface, wherein each of the wash beam patterns define a boundary, the boundary defining a substantially continuous curve, whereby the substantially continuous curve is substantially free of inflection points; and

merging the plurality of wash beam patterns to uniformly light the surface.

12. A lighting apparatus, comprising:

means for providing light;

means for reflecting at least a portion of light from the means for providing light to produce a scallop beam pattern on a surface; and

means for allowing at least another portion of light from the means for providing light to be reflected to produce another beam pattern on the surface, wherein the scallop beam pattern and the other beam pattern merge to form a wash beam pattern.

13. The apparatus of claim 12, wherein the wash beam pattern defines a boundary, the boundary defining a substantially continuous curve.

14. The apparatus of claim 13, wherein the substantially continuous curve is substantially free of inflection points.

15. The apparatus of claim 12, wherein the other beam pattern is substantially trapezoidal in shape.

16. A lighting apparatus, comprising:

means for providing light;

means for reflecting at least a portion of light from the means for providing light to produce a scallop beam pattern on a surface; and

means for allowing at least another portion of light from the means for providing light to be reflected to produce a trapezoidal beam pattern on the surface, wherein the scallop beam pattern and the trapezoidal beam pattern merge to form a wash beam pattern, whereby the wash beam pattern defines a boundary, the boundary defining a substantially continuous curve which is substantially free of inflection points.

17. A lighting apparatus, comprising:

means for providing a plurality of light sources;

means for reflecting at least a portion of light from the means for providing a plurality of light sources to produce a plurality of scallop beam patterns on a surface; and

means for reflecting at least another portion of light from the means for providing a plurality of light sources to produce a plurality of other beam patterns on the surface, wherein the plurality of scallop beam patterns and the plurality of other beam patterns merge to form a plurality of wash beam patterns.

18. The apparatus of claim 17, wherein the wash beam pattern defines a boundary, the boundary defining a substantially continuous curve.

19. The apparatus of claim 18, wherein the substantially continuous curve is substantially free of inflection points.

20. The apparatus of claim 17, wherein the other beam pattern is substantially trapezoidal in shape.

21. The apparatus of claim 17, wherein the plurality of wash beam patterns merge to uniformly light the surface.

22. A lighting apparatus, comprising:

means for providing a plurality of light sources;

means for reflecting at least a portion of light from the means for providing a plurality of light sources to produce a plurality of scallop beam patterns on a surface;

means for reflecting at least another portion of light from the means for providing a plurality of light sources to produce a plurality of trapezoidal beam patterns on the surface, wherein the plurality of scallop beam patterns and the plurality of trapezoidal beam patterns merge to form a plurality of wash beam patterns, whereby the wash beam pattern defines a boundary, the boundary defining a substantially continuous curve which is substantially free of inflection points, and whereby the plurality of wash beam patterns merge to uniformly light the surface.
