| Title: |
Anti-Noise System for a Moving Object |
| Abstract: |
A stage lighting device has a light source for emitting light and a light
modifying element for modifying such light. The light modifying element is
coupled to a driven element which is rotationally coupled to a structural
member so as to be rotatable about a first axis. The device has a
noise-producing motor assembly with an output shaft. A driving element is
coupled to the output shaft to be rotationally driven by the output shaft
about a second axis. The driving element is coupled to the driven element
by an endless loop element so as to rotationally drive the driven element
about the first axis. A vibration-isolating mounting structure couples a
motor assembly to the structural member and includes surfaces which
vibrationally isolate the motor assembly from the structural member to
attenuate vibration transferred from the motor assembly to the structural
member. The mounting structure is pivotally coupled to the structural
member with a pivotal range of motion about a pivot axis which is
substantially parallel to the first axis. A tensioner couples the
structural member to the mounting structure to bias the mounting structure
in a first direction about the pivot axis so as to maintain a tension in
the endless loop element.
