Abstract: The degree of diffusion of a light source can be varied by surrounding the light source with a liquid crystal cell. The light source is positioned at the focal point of a reflector and the liquid crystal cell surrounds the light source. When the cell is unexcited, the light rays which emanate from the source are virtually unaffected as they pass through the cell striking the wall of the reflector. In this state the light rays are projected nearly straight out of the reflector, providing illumination for objects at great distances from the source. When the cell is excited, scattering occurs and the light rays are diffused as they are re-emitted from the liquid crystal. The diffusion shifts the apparent light source points away from the focal point. This diffusing effect causes the light which is projected from the reflector to illuminate a wide area in close proximity to the lamp.

Abstract: A flash device of the type in which the flash tube is coated with a trigger electrode and is positioned in contact with the back metal constituting part of the reflector so that when the trigger signal is applied directly to the back metal, the flash tube is triggered.
