Abstract

The present invention provides a light display system for projecting a double-pattern light display. A luminaire holding the lamp and light control devices is fixed to a first housing that in turn is nonrotatably mounted mounted to a control bar. A second housing containing a fixed reflector apparatus adapted to receive the light beam from the luminaire is connected to and rotatable relative to the first housing about a first axis. The second housing contains a reflector rotatable about a second axis. The rotatable reflector receives the light beam from the fixed reflector apparatus and projects the beam in a geometric configuration, preferably a vertical plane that contains the first axis. A pan driver attached to the first housing rotates the second housing about the first axis by way of a gear and belt mechanism that is connected to a cylindrical mounting member attached to the second housing. The stationary luminaire directs the light beam through a cylindrical passage in the cylindrical mounting member. A tilt driver attached to the second housing rotates the rotatable mirror about the second axis, which is perpendicular to the first axis. A slip-ring connector connected to the cylindrical mounting member transmits electrical power from the power source to tilt driver. The light beam is thus moved simultaneously about two axes so as to cast a double patterned light on the environment.
