Light dimming device, in particular for lighting units such as studio lights or similar optical devices

摘要

Blades (1) swivel round a linking point (4) outside a light aperture and are moved by a drive in a synchronized manner into and out of the path of rays. The blades take the shape of a sickle. As they move the tips of each sickle taper into the optical axis (5) of this device, so that a beam cluster is distributed into several double corners inscribed in circles (7) stretching radially and curved towards the optical axis.
