| Title: |
Lighting Fixture |
| Abstract: |
A lighting fixture projects a light beam for spot lighting in theater
stages, cinema and television studios and the like. The fixture includes a
light source at one end of a housing having a light beam exit aperture at
the opposite end thereof, the light source and aperture being arranged
generally concentric with a longitudinal or optical axis of the lighting
fixture. One or more beam-shaping blades, and preferably also other light
beam influencing elements, such as one or more lenses, an iris, and/or a
pattern or gobo, are arranged along the path of the light beam along the
longitudinal axis through the housing from the light source to the
aperture. The position of the beam-shaping blade or blades, and preferably
of all the light beam influencing elements, is adjustable relative to the
longitudinal axis. The fixture produces a well-defined light beam or light
cone with a geometry, angle of conicity and focal point that may be
altered manually or by remote control.
