| Title: |
Iris Diaphragm System |
| Abstract: |
An iris diaphragm comprises a stationary ring, a rotatable adjusting
ring, and a plurality of shutter blades. The plurality of shutter blades
forms a diaphragm aperture inside the stationary ring and rotation of the
adjusting ring moves the shutter blades inside the stationary ring
whereby the size of the diaphragm aperture can be changed. The shutter
blades are formed as a flat opaque surface and at least one of the
shutter blades comprises at least one transparent region formed in said
opaque surface. A light fixture comprises such iris diaphragm arranged
between a light source generating a light beam and an optical assembly
configured to project the light beam along an optical axis.
