    Abstract: A photoflash lamp-reflector module particularly suitable for use in a four-sided photoflash array such as a flashcube. The reflector is formed in the shape of a parabola having curved winged portions whose tangents form an angle of more than 45* with respect to the optical axis of the reflector. Due to the curvature of the winged portions, a series of reflectors may be arranged in a back-to-back relationship with each other to form a flashcube assembly without any interference or distortion occurring between the winged portions of adjacent reflectors. In a preferred embodiment, the reflector is formed at its innermost region with a transversely extending channel-shaped recessed area for snugly accommodating a minor portion of the circumferential extent of a tubular flashlamp throughout substantially its full length.
