Claim of US Patent No. 10,161,595

10. An automated luminaire, comprising:a plurality of light emitting diode (LED) modules;
a corresponding plurality of reflective optics optically coupled to the plurality of LED modules, wherein each reflective optic comprises:
a receiving orifice;
an output face, configured to pass light rays emitted from the reflective optic; and
a central light block,
wherein the receiving orifice is configured to receive light rays emitted by its associated LED module, and wherein the central light block is configured to intersect an optical axis of the reflective optic, to cover a central region of the output face, and to block received LED module light rays that are reflected within the reflective optic and have a beam angle that is greater than a desired output beam angle of light emitted from the reflective optic, wherein the central light block comprises a material that is adhered to a center of the output face and a plurality of louvers corresponding to the plurality of reflective optics, wherein each louver is configured to align with the output face of its associated reflective optic, and wherein each louver is configured to block light rays emitted from its associated reflective optic with a beam angle that is greater than the desired output beam angle.
