| Title: |
Two-Axis Beam Steering System for Use in Automated Light Fixtures |
| Abstract: |
A beam steering mechanism for deflecting a light beam along any selected
azimuth and elevational direction. The beam is movable without limitation
about a pan axis and through a range of 180 degrees about a tilt axis, by
drive motors that are rigidly mounted to a housing and are not bodily
moved with the light beam. Movement about the pan axis is effected by
rotation of a first mirror mounted in a first rotatable cylinder. Movement
about the tilt axis is effected by rotation of a second mirror mounted in
a second cylinder that is panned with the first cylinder and is itself
mounted for rotation about the tilt axis.
