| Title: |
Stage Lighting Lamp Unit and Stage Lighting System Including Such Unit |
| Abstract: |
A stage lighting lamp unit includes a processor for receiving control data
from a remote console. Beam orientation data for the lamp unit is passed
to the lamp in the form of the x, y and z co-ordinates of a point in space
through which the beam is to pass. The processor divides the required lamp
travel into a number of stages dependent on execution duration data sent
with the position data, and calculates, for each stage, a new value for
pan and tilt angles for the lamp. These values are passed to pan and tilt
controlling co-processors which control servo-motors for pan and tilt
operation. The lamp unit also incorporates a rotatable shutter for
interrupting the lamp beam when required. The shutters of all the lamps in
a system can be instructed from the remote console to open and close in
synchronism, thereby providing a stroboscopic effect.
