Abstract

A photographic light box comprised of a housing having a side wall with a pair of opposed ends, one of the ends being larger than the other end and the side wall progressively increasing in cross section as the smaller of the two ends is approached. A panel capable of transmitting diffused light is secured to the side wall across the larger end of the housing, the smaller end being open to receive a light source including a lamp disposed within the housing and capable of being energized to produce light. The housing has a plurality of flexible rods extending along the side wall at spaced locations thereon and the ends of the rods near the smaller end of the housing are inserted into holes in spaced block carried by a strap surrounding the light source as the light source extends into the opening of the housing. The rods are bent to permit insertion of the ends of the rods into the block and this bending of the rods provides a bias force to cause the housing to expand and substantially stretch the light diffusing panel at the larger end of the housing. The housing can be collapsed when not in use and rolled into a compact shape for insertion into a tube for shipment or storage.
