Patent ID: 8113691

Claim:
A luminaire comprising: a light source for generating a light beam; a first overlapping pair of light color modulation filters driven in opposing rotational directions by a first motor; a second overlapping pair of light color modulation filters driven in opposing rotational directions by a second motor; a first rotational axle shared by one light color modulation filter from the first light color modulation filter pair and one light color modulation filter from the second light color modulation filter pair where rotation of the first axle is driven by the first motor and drives the rotation of the light color modulation filter from the first light color modulation filter pair that shares the first axle while the light color modulation filter from the second pair that shares the first axle floats on the axle and is not driven by rotation of the first axle; a second rotational axle shared by one light color modulation filter from the first light color modulation filter pair and one light color modulation filter from the second light color modulation filter pair where rotation of the second axle is driven by the second motor and drives the rotation of the light color modulation filter from the second light color modulation filter pair that shares the second axle while the light color modulation filter from the first pair that shares the second axle floats on the axle and is not driven by rotation of the second axle.
