Abstract
A light beam intensifier (10) having a paraboloidal reflector (12) a mirror (14) a single light tube (16) and window (18). The mirror (14) is placed forward of the forcal point f of the reflector (12) and has the light tube (16) affixed thereto to be positioned coincident with the focal point f. As the light tube (16) is energized, light rays (52) emanating directly therefrom are reflected from the parabolic reflector (12) to form a first beam path and the forward shining light rays (54) are reflected from the reflective surface (34) of the mirror (14) to be reflected off the paraboloidal reflector (12) to form a composite light beam path (56) having a predetermined pattern.
