Abstract: A lighting apparatus for illumination of a surface. The disclosed embodiment includes a source of light, a reflector with the source of light at its focus point, a lens for concentrating light from the source to an area to be illuminated, and a motor. The motor rotates the source of light, the reflector and the lens at a rate of at least ten cycles per second, thereby moving the illuminated area along a path at the same rate.

The rate of movement of the illuminated area along the path is faster than the human eye's ability to integrate the discontinuities of the individual illuminated areas and thus the entire path has the appearance of being illuminated simultaneously.

Abstract: A hanger on which one or a plurality of electric lamps is slidably positionable along an elongated housing having non-electrified rails. The hanger includes a different resiliently extensible helical electrical cord to supply electric power to each lamp. Each helical cord is longitudinally disposed within the housing; when there is more than one lamp, the helical cords of the additional lamps are each disposed in a separate container within the housing to prevent entanglement of the cords when the positions of the lamps are adjusted. The helical cords in their relaxed positions have a diameter greater than the width of a slot in the housing so that the helical cord cannot protrude or fall from the housing. The present hanger allows installation of the unit without the services of an electrician, and because the lamps can slide on the rails, the position of each lamp is fully adjustable longitudinally of the housing.
