| Title: |
Low-Inertial Beam Direction Lighting System |
| 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.
