| Title: |
Stage Lighting Optical System Having Spot and Beam Effects |
| Abstract: |
A stage lighting optical system includes a light source assembly from
which condensed light can be emitted, an object assembly, and a zoom lens
assembly, which are located in a same primary optical axis direction.
Light from the light source assembly is cast by the object assembly and
the zoom lens assembly. The object assembly includes an object for beam
mode assembly and an object for gobo mode assembly that can be switched
with each other and enter to the primary optical axis. The light source
assembly can move forward or backward along the primary optical axis with
respect to the object assembly. When the light source assembly moves
forward to a first position with respect to the object assembly, the beam
mode assembly is switched to the primary optical axis. When the object
for beam mode assembly moves backwards to a second position with respect
to the object assembly, the object for gobo mode assembly is switched
into the primary optical axis.
