Abstract: The light reflector is for use in photography and comprises a cloth 1 raised on radial ribs 2 each of which has a proximal end 3 and a distal end 4. The distal ends 4 of ribs 2 are removably engaged in pockets 5 formed at the angle edges 6 of the cloth 1. Each of the proximal ends of the ribs is removably engaged into a socket 29 pivotally mounted on an armature 10 adapted to be fastened on a lamphead 17. The central portion of cloth 1 is engaged on a sleeve which is part of the armature 10. A locking assembly 36 is mounted on each socket 29 to allow locking thereof in a position where it extends peripherally of the armature 10.
