| 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 and projecting a primary first light beam is fixed to a
first housing that in turn is nonrotatably mounted to a control bar. A
second housing containing a fixed reflector apparatus adapted to receive a
light beam from the luminaire is connected to and rotatable relative to
the first housing about a first axis. At least two mirrors fixed to the
second housing are positioned at an angle relative to the first axis and
receive portions of the first light beam as second light beams. The fixed
mirrors are rotatable with the second housing about the first axis. The
rotatable mirrors project the second light beams to at least two rotatable
mirrors each associated with a fixed mirror and the rotatable mirrors
project the second light beams as third light beams about a second axis
transverse to the first axis. A tilt driver attached to the second housing
rotates the rotatable mirrors about the second axis. Shafts radially
extend from the tilt drivers along the second axis to the rotatable
mirrors for rotation and support. The light beams are thus moved
simultaneously about two axes so as to cast double patterned lights on the
environment.
