SPEED RING FOR PHOTOGRAPHIC LIGHTING APPARATUS

摘要

A speed ring can be used to attach a light diffuser, such as a soft box, to a photographic lighting apparatus. For example, the speed ring can couple a light diffuser to a lamp housing of a photographic lighting system. The speed ring may have an overall rectangular appearance, such as a square appearance, and may be described generally as a rectangular frame, such as a square frame, with special adaptations to attach a light diffuser to a photographic lighting apparatus.

主权项

1. A speed ring for a photographic lighting apparatus, the speed ring comprising:
multiple elongate first and second members in a circumferential arrangement of which the elongate first members form parallel straight sides, the circumferential arrangement having a normal direction perpendicular to a plane of the elongate members and having a reference direction perpendicular to the normal direction and perpendicular to the parallel straight sides, the elongate first members having a member thickness in the normal direction; and connection braces each coupling one of the elongate first members to one of the elongate second members, each of the connection braces having a protrusion extending in the normal direction and a flange extending parallel to the reference direction, the flange having a flange thickness no greater than 12.2 millimeters minus the member thickness of the elongate first members in the normal direction, the protrusion having a cavity with a mouth whose cross-sectional area when viewed along the normal direction does not overlap the flange.
