Abstract: A reflector of a photo flash device bounds a space for a light source. The space has an open side across which a light-transmissive shield extends that permits light from the source to issue through the opening at a first angle of emergence. A wide-angle light-transmissive shield is hinged to a frame of the first-mentioned shield and can be swung into and out of an operating position in which it is located in front of the first-mentioned shield and causes the issuing light to emerge at a larger angle of emergence. This permits a user to increase or decrease the area which he wishes to have illuminated when the device is operated.

Abstract: A flash device has a housing, a cylindrical reflector unit mounted in the housing for turning movement about its longitudinal axis, and a flash lamp positioned in the housing so that flashes emitted by the lamp are reflected by the reflector unit when the latter is turned to respective different positions.
