SYSTEM AND METHOD FOR CONTROLLING LIGHT OUTPUT IN A LED LUMINAIRE
Described is a method for controlling the beam angle of individual lighting devices in luminaires, specifically to a method relating to providing the coordinated control of the beam spread of LEDs in a wash light. The LEDs may be mounted in a plurality of modules. The LED may be in a linear arrangement in a module. The LEDs may be mounted in a plurality of modules that are arrayed in a two dimensional array. The LEDs in the linear arrangement form modular groups where the beam angle of each modular group may be controlled independent of other modular groups.
1 . A luminaire comprising:
a carrier housing into which are mounted
a plurality of light emitting modules each fitted with
a plurality of beam control systems each of which alter the beam angle of a light emitting module where the plurality of light emitting beam control systems are independently controlled.
2 . The luminaire of claim 1 in which each module further comprises a plurality of LED sub-modules.
3 . The luminaire of claim 2 where the first light-emitting module's LED sub-modules are arranged in a linear row.
4 . The luminaire of claim 4 where the second light-emitting module's LED sub-modules are arranged in a linear row.
5 . The luminaire of claim 4 where a third second light-emitting module's LED sub-modules are arranged in a linear row.
6 . The luminaire of claim 5 where the light emitting modules each include the same number of LED Sub-modules.
7 . The luminaire of claim 6 where the light emitting modules mounted in the carrier in parallel to each other forming a rectangular array.
8 . The luminaire of claim 5 where the light emitting modules have different number of LED Submodules
9 . The luminaire of claim 2 where a plurality of the LED sub-module contains four colors of LEDs.
10 . The luminaire of claim 2 where each light-emitting module contains five or more colors of LEDs.
