Abstract
A light source, such as a laser diode, is positioned on a mount bed facing upwardly. A lens device is supported a support member extending upwardly from the mount bed. The lens device consists of a concave lens and convex lens and is provided to convert the rays of light emitted by the light source to parallel rays of light perpendicular to a true horizontal plane. The concave lens is suspended above the light source by plural wires from the support member. The convex lens is supported above the concave lens by at least one arm attached to the support member. A motorized rotatable reflector device is mounted on the support member above the lens device and reflects the parallel rays of light therefrom in a horizontal direction.
