Abstract

A luminaire comprised generally of a mounting plate including a plurality of mounting blocks secured to the mounting plate; and a plurality of LEDs, wherein at least one of the LEDs is positioned upon each of the mounting blocks. The mounting blocks include face portions and may be arranged in a plurality of configurations on the mounting plate.

Claims

1. A luminaire for providing illumination to a plurality of lighting areas comprising:

a mounting plate having a mounting surface and a plurality of individually positionable mounting blocks removably secured to said mounting surface of said mounting plate, each of said mounting blocks having a mounting face positioned at a fixed predetermined plate angle relative to said mounting plate;

wherein said plate angle of each of said mounting blocks is fixed and determinable prior to securing of said mounting blocks to said mounting plate, and wherein each of said mounting blocks comprises a bottom edge which in use is parallel to and sits flush against said mounting surface of said mounting plate;

a plurality of light emitting diode housings, each of said light emitting diode housings contains no more than one light emitting diode and is positioned on said mounting face of one of said plurality of mounting blocks, whereby each mounting block contains no more than one light emitting diode housing; and

whereby each of said light emitting diode housings is positioned at a predetermined angle relative to said mounting plate by virtue of said mounting face and each of said light emitting diode housings is not in direct contact with the mounting plate; and

,

wherein said mounting face of said mounting blocks are angled at predetermined varying pitches relative to said mounting plate.

2. A luminaire as claimed in claim 1, wherein said mounting blocks are secured to said mounting plate in a patterned array to illuminate a plurality of lighting areas.

3. A luminaire as claimed in claim 2 wherein said patterned array is a plurality of concentric circles.

4. A luminaire as claimed in claim 2 wherein said patterned array is a matrix of predetermined size.

5. A luminaire as claimed in claim 1 wherein said mounting plate is substantially planar and uninterrupted.

6. A luminaire as claimed in claim 1 wherein said mounting blocks have a plurality of different heights.

7. A luminaire as claimed in claim 1 wherein said mounting plate further comprises a plurality of orienting surfaces to which said mounting blocks are secured by one or more screw elements.

8. A luminaire for providing illumination to a plurality of lighting areas comprising:

a mounting plate having a mounting surface and a plurality of individually positionable mounting blocks removably secured to said mounting surface of said mounting plate, each of said mounting blocks having a fixed bottom surface most closely adjacent said mounting plate, each mounting block having a mounting face positioned at a fixed predetermined plate angle relative to said mounting plate and at a fixed predetermined surface angle relative to said bottom surface, and wherein each of said mounting blocks comprises a bottom edge which in use is parallel to and sits flush against said mounting surface of said mounting plate;

wherein said mounting face of said mounting blocks are angled at predetermined varying pitches relative to said mounting plate; and

wherein said fixed plate angle of each mounting block is the same as said fixed surface angle thereof;

a plurality of light emitting diode housings, each of said light emitting diode housings contains no more than one light emitting diode and is positioned on said mounting face of one of said mounting blocks, whereby each mounting block contains no more than one light emitting diode housing; and

whereby each of said light emitting diode housings is positioned at a predetermined angle relative to said mounting plate by virtue of said mounting face and each of said light emitting diode housings is not in direct contact with the mounting plate.

9. A luminaire as claimed in claim 8 wherein said mounting blocks are secured to said mounting plate in a patterned array to illuminate a plurality of lighting areas.

10. A luminaire as claimed in claim 9 wherein said patterned array is a plurality of concentric circles.

11. A luminaire as claimed in claim 9 wherein said patterned array is a matrix of predetermined size.

12. A luminaire as claimed in claim 8 wherein said mounting plate is substantially planar.

13. A luminaire as claimed in claim 12 wherein said mounting plate is uninterrupted.

14. A luminaire as claimed in claim 8 wherein said plurality of mounting blocks have a plurality of different heights.

15. A luminaire as claimed in claim 8 wherein said mounting plate further comprises a plurality of orienting surfaces to which said mounting blocks are secured by one or more screw elements.

16. A luminaire as claimed in claim 15 wherein each of said of said orienting surfaces is substantially planar and uninterrupted.
