| Title: |
Dichroic Patterning for Subtractive Color Mixing |
| Abstract: |
A color wheel for use in an automated luminaire includes a transparent
substrate and a patterned dichroic filter coating on the transparent
substrate. The pattern includes a first region and a second region. The
first region includes unconnected coated dots, most of the coated dots
having a substantially equal first size. The coated dots vary in density
from a lower density at a first end of the first region to a higher
density at a second end of the first region. The second region includes a
contiguous dichroic filter coating that includes unconnected uncoated
holes, most of the uncoated holes having a substantially equal second
size. The uncoated holes vary in density from a higher density at a first
end of the second region to a lower density at a second end of the second
region. The first end of the second region abuts the second end of the
first region.
