Abstract
A reflector includes one closed end, one open end and highly reflecting curving walls. The walls are symmetrical about at least one axis of symmetry. The walls include a first segment and other segments. Briefly described, according to one aspect of the present invention, a camera flash unit for illumination of an associated target area has a light source providing light defined as light rays, a reflector directing the light rays from the light source towards the associated target surface and a refractive lens component. The reflector includes one closed end, one open end and highly reflecting curving walls. The walls are symmetrical about at least one axis of symmetry. The refractive lens component is located at the open end of the reflector. It has two surfaces--a back side surface facing said light source and a front side surface. One of the surfaces has a cylindrical shape, the other of the two surfaces has a toroidal shape.
