Abstract

Described is a method for controlling the movement of LED devices in luminaires, specifically to a method relating to allowing both synchronized and independent pan and tilt movement of LED light modules in a light curtain. The LEDs may be mounted in a plurality of modules. The modules may be in a linear arrangement. The LEDs may be mounted in a plurality of modules that are arrayed in a two dimensional array. The modules in the linear arrangement or in the two dimensional array may be mounted in groups forming modular group assemblies where modular group assembly are independently articulated to pan and/or tilt the modules mounted thereon independent of other modular group assemblies.

First claim

What is claimed is:

1. A luminaire comprising:
a plurality of module group assemblies into each of which is mounted at least one light emitting module;
a head in which the plurality of module group assemblies is mounted in a coplanar arrangement;
a global articulator is a first global articulator configured to articulate the head around a first axis of rotation parallel to the plane of the coplanar arrangement and the luminaire further comprises a second global articulator configured to articulate the head around a fourth axis of rotation orthogonal to the first axis of rotation;
a first plurality of independent articulators, each of which is configured to articulate a corresponding module group assembly about an individual second axis of rotation parallel to the plane of the coplanar arrangement; and
a second plurality of independent articulators, each of which is configured to articulate a corresponding module group assembly about an individual third axis of rotation parallel to the plane of the coplanar arrangement and orthogonal to the second axis of rotation of the module group.

2. The luminaire of claim 1 , wherein the first and second global articulators comprise respective first and second electric motors.

3. The luminaire of claim 1 , wherein the first and second pluralities of independent articulators comprise corresponding first and second pluralities of electric motors.

4. The luminaire of claim 1 , wherein at least one of the light emitting modules comprises an LED.

5. The luminaire of claim 4 , wherein the at least one of the light emitting modules comprises one each of red, green, blue, and white LED dies.

6. The luminaire of claim 4 , wherein the at least one of the light emitting modules is configured to be adjusted for at least one of color and beam angle of a light beam emitted by the light emitting module.

7. The luminaire of claim 4 , wherein the at least one of the light emitting modules comprises a system of one or more lenses configured to adjust at least one of beam angle and focus of a light beam emitted by the light emitting module.

8. The luminaire of claim 4 , wherein the at least one of the light emitting modules comprises at least one of a gobo wheel and a rotating gobo wheel.

9. The luminaire of claim 4 , wherein the at least one of the light emitting modules comprises at least one of a collimating and mixing optic and a light integrator optic.
