| Title: |
Control System For Optical Media in a Luminaire |
| Abstract: |
A zoom lens system includes a motor driven lens assembly that is movable on
a track in a normal movement range for adjusting the light beam range
angle of a luminaire. A pair or doors are pivoted to opposite sides of the
frame of the lens assembly and are normally biased to an inactive position
where the doors are parallel to and outside of the light path in the
luminaire. The doors hold optical media such as diffuser gels. The lens
assembly can be moved beyond the normal movement range to an actuation
position where projections on the doors engage actuation abutments
adjacent the track to move the doors to an active position overlying the
lens with the optical media in the light path. A latch holds the door in
the active position. The lens assembly can be moved beyond the actuation
position to a deactivation position where a deactivation abutment releases
the latch freeing the doors to return to the inactive positions.
