Light diffuser

摘要

The light diffuser (1) has a holder device (2) comprising an adapter ring (4) with a light-transmissive disk i.e. glass disk (5), for fastening to a spotlight and for airtightly connecting an inflatable sack (3). An end of the sack connected to the ring is airtightly surrounded by a fastening ring (6). The fastening ring is provided against a radially extending sealing surface on the adapter ring by three quick-closures (7) that are uniformly arranged over a circumference of the light diffuser. A flat ring seal is made of silicone, rubber or elastic sealing material.
