Abstract
A reflector specially designed for street lighting and applicable to an elongated light source, characterized in that a part of the reflector wall is formed by two partial revolution paraboloids, which extend on both sides of a perpendicular plane to the axis of the reflector, and in which are the end of the light source and the foci of the paraboloids, so that the rays of light reflected by said paraboloid parts are emitted essentially through the aperture of the reflector.
