| Title: |
Light Projector |
| Abstract: |
A theatrical spotlight for directing an adjustable diameter focused beam of
light at either fixed or moving objects. A high-intensity beam of light
passes upwardly from a xenon lamp through a shutter, an iris diaphragm and
an adjustable lens system. A mirror is positioned to reflect the light
beam to the target. The beam diameter and focus are adjusted with a single
control lever which simultaneously adjusts the lens system and the iris
diaphragm. The shutter is adjustable to cut off either a portion of or all
of the light beam.
