Abstract

A reflector assembly for a lighting apparatus, the reflector assembly comprising two or more reflector modules configured for associating with one or more light sources, each reflector module comprising one or more reflectors for being located adjacent to a light source when the reflector module is associated with the one or more light sources, the one or more reflectors configured to reflect light from the adjacent light source. The reflector modules may further comprising a cover plate defining a plurality of light source apertures for allowing a light source to protrude through the cover plate, at least a first of the one or more light source apertures disposed adjacent to an overhead reflector and at least a second of the one or more light source apertures disposed adjacent to a lateral reflector. The reflector assembly can comprising any number of reflector modules and the reflector modules can be arranged in different configurations to create different light distributions with the same reflector modules.

Claims

1. A reflector assembly for a luminaire, the reflector assembly comprising:

a first reflector module configured for associating with one or more light sources to create a first light distribution, the first reflector module comprising one or more reflectors for being located adjacent to a light source when the first reflector module is associated with the one or more light sources, the one or more reflectors configured to reflect light from the adjacent light source; and

a second reflector module configured for associating with one or more light sources to create a second light distribution, the second reflector module comprising one or more reflectors for being located adjacent to a light source when the second reflector module is associated with the one or more light sources, the one or more reflectors configured to reflect light from the adjacent light source;

wherein the first light distribution and the second light distribution combine to form a third light distribution different than either the first light distribution or the second light distribution.

2. The reflector assembly of claim 1, further comprising a cover plate defining a plurality of light source apertures for allowing a light source to protrude through the cover plate.

3. The reflector assembly of claim 1, each of the reflector modules further comprising a cover plate defining a plurality of light source apertures for allowing a light source to protrude through the cover plate, at least a first of the one or more light source apertures disposed adjacent to an overhead reflector and at least a second of the one or more light source apertures disposed adjacent to a lateral reflector.

4. The reflector assembly of claim 1, each of the reflector modules further comprising a cover plate defining a plurality of light source apertures for allowing a light source to protrude through the cover plate, a plurality of the light source apertures aligned in a row and located adjacent to a lateral reflector oriented parallel to the row of light source apertures.

5. The reflector assembly of claim 1, the one or more reflectors comprising both a lateral reflector and an overhead reflector associated with one of the one or more light source apertures.

6. The reflector assembly of claim 1, the at least one reflector having a reflective surface facing the adjacent light source and each reflective surface defining a plane oriented at an angle of about 0°

to about 45°

from perpendicular to a plane defined by the two or more reflector modules.

7. The reflector assembly of claim 1 comprising four reflector modules pin-wheeled.

8. The reflector assembly of claim 1, each of the two or more reflector modules are oriented to direct light in the same directions from the one or more associated light sources.

9. The reflector assembly of claim 1, each of the two or more reflector modules are oriented to direct light from the one or more light sources in the +X, +Y, −

Y and +Z directions of the reflector module.

10. The reflector assembly of claim 1 wherein at least two of the two or more reflector modules are substantially identical.

11. The reflector assembly of claim 1 wherein at least two of the two or more reflector modules are configured differently from each other.

12. The reflector assembly of claim 1 wherein at least one light source is an LED.

25. The reflector assembly of claim 1 wherein the first light distribution is substantially the same as the second light distribution.

26. The reflector assembly of claim 1 wherein the first light distribution is different from the second light distribution.

13. A luminaire comprising:

one or more light sources;

a reflector assembly comprising a first reflector module, the first reflector module associated with at least one of the one or more light sources to create a first light distribution, the first reflector module comprising one or more reflectors adjacent to the at least one of the one or more light sources, the one or more reflectors configured to reflect light from the adjacent light source; and

the reflector assembly comprising a second reflector module, the second reflector module associated with at least one of the one or more light sources to create a second light distribution, the second reflector module comprising one or more reflectors adjacent to the at least one of the one or more light sources, the one or more reflectors configured to reflect light from the adjacent light source;

wherein the first light distribution and the second light distribution combine to form a third light distribution different than either the first light distribution or the second light distribution.

14. The luminaire of claim 13, at least one reflector module further comprising a cover plate defining a plurality of light source apertures and an associated light source protruding there through.

15. The luminaire of claim 13, each of the reflector modules further comprising a cover plate defining a plurality of light source apertures, at least a first of the one or more light source apertures disposed adjacent to an overhead reflector and at least a second of the one or more light source apertures disposed adjacent to a lateral reflector.

16. The luminaire of claim 13, each of the reflector modules further comprising a cover plate defining a plurality of light source apertures through which associated light sources protrude, a plurality of the light sources aligned in a row oriented parallel to an adjacent lateral reflector.

17. The luminaire of claim 13, the one or more reflectors comprising both a lateral reflector and an overhead reflector associated with one of the one or more light sources.

18. The luminaire of claim 13, the at least one reflector having a reflective surface facing the adjacent light source and each reflective surface defining a plane oriented at an angle of about 0°

to about 45°

from perpendicular to a plane defined by the two or more reflector modules.
