Abstract
The casing of a photoflash unit has an upper portion 1, the bottom of which is pivoted on a horizontal axis A--A at the top of the bottom portion 2, so that the top portion can be tilted back to raise the plane of two of the three reflectors lined up with the axis of tilt as their focal line, on which a photoflash tube is disposed. The third reflector, located in the middle between the two that can be tilted up, is fixed with respect to the bottom part of the casing and provides the minimum necessary amount of direct illumination.
