摘要:
A color wheel includes a motor and attached color ring, which includes a hub, a carrier and filter segments for being inserted into a light path. The geometry of the carrier is such that circular rings exist where the top view of the carrier fits into the area of the circular rings. The corresponding circular ring with minimum area defines outer and inner radii. The filter segments are translucent and extend radially into the circle with inner radius to contribute to a ring shaped area that is translucent to the light path as said color ring is rotated. The hub is attached to the motor and provides rotation of the color ring about an axis. At least one of the filter segments is attached to said hub. The attachment is less rigid against centrifugal forces than the fixation of the segments to the carrier so that rotation of the color ring leads to radial compressive forces exerted on all filter segments.
