Abstract
A strobe light mounting system for underwater cameras with arm segments clamped together with side clamps that grasp balls on the ends of the arm segments. The arm segments are rigid, light, and low in water resistance because they have four longitudinal channels pierced by mutually orthogonal transverse holes of large diameter so that longitudinal ribs are preserved at the maximum diameter of the arm segment. Water flows easily through the orthogonal holes permitting easy movement underwater.
Claims12
An adjustable light support system adapted to be fastened to a camera, and adapted for use in an underwater environment comprising in combination:
- a plurality of arm segments, each of said arm segments having four longitudinal channels formed along the length of the arm segment and a series of orthogonal intersecting holes extending transverse to the length of the arm segment from one channel to another channel, the distance along the length of the arm segment and between the holes being less than fifty percent of the diameter of the transverse holes, so as to permit easy water flow through the holes;
- a plurality of side clamps adapted to clamp together a pair of arm segments;
- a tray adapted to be fastened to a camera;
- an arm segment adapted to connect to said tray;
- and
- light support means adapted to connect to an arm segment.
