Patent ID: 7832902

Claim:
An apparatus comprising a dichroic color mixing system for a multiparameter stage light comprising: a plurality of dichroic color mixing flags wherein each of the plurality of dichroic color mixing flags has a substantially circular shape having a perimeter and at least two of the plurality of dichroic color mixing flags have a transmitting color which is the same; a plurality of mechanical components; a plurality of motors, one for each of the plurality of mechanical components; wherein each of the plurality of mechanical components is fixed to a periphery of a corresponding one dichroic color mixing flag of the plurality of dichroic color mixing flags in a manner so that each corresponding one dichroic color mixing flag of the plurality of dichroic mixing flags cannot rotate with respect to the mechanical component to which it is fixed; wherein each mechanical component of the plurality of mechanical components can move the dichroic color mixing flag which is fixed to it into a light path without moving any other dichroic color mixing flag; wherein each mechanical component of the plurality of mechanical components has a first end which is fixed to and in direct contact with its corresponding one dichroic color mixing flag at a first point inside the perimeter of the substantially circular shape of its corresponding one dichroic color mixing flag; wherein each mechanical component of the plurality of mechanical components has a second end opposite the first end; and wherein each mechanical component of the plurality of mechanical components is fixed to its corresponding one dichroic color mixing flag so that each mechanical component of the plurality of mechanical components extends from its first end at the first point inside the perimeter of the substantially circular shape of its corresponding one dichroic color mixing flag to its second end at a second point outside the perimeter of the substantially circular shape of its corresponding one dichroic color mixing flag, wherein the second end of each of the plurality of mechanical components is not overlapped by the substantially circular shape of its corresponding one dichroic color mixing flag; wherein the second end of each of the plurality of mechanical components is fixed to a corresponding one motor of the plurality of motors which is configured to a translate a corresponding one dichroic color mixing flag of the plurality of dichroic color mixing flags into the light path; and wherein each of the dichroic color mixing flags is fixed to the first end of its corresponding mechanical component and the second end of each of the corresponding mechanical components is fixed to its corresponding one motor of the plurality of motors so that each of the dichroic color mixing flags cannot rotate unless translated with respect to its corresponding one motor.
