| Patent Number: |
9217559 |
| Title: |
Moving Head Light Fixture with Yoke and Head Position Encoding Means |
| Abstract: |
The present invention relates to a moving head light fixture comprising:
a base; a yoke rotatable connected to the base; a head rotatable
connected to the yoke. The head comprises at least one light source
generating light. An actuator is adapted to rotate the yoke or the head.
Magnetic means is attached to the axel of the actuator and generated a
magnetic field, which is perpendicular to the actuator axel. A magnetic
encoder is fixed in relation to the axel and provides at an axel position
signal based the magnetic field is indicative of the angular position of
the axel in relation to the magnetic encoder. Indication means provides
an indication signal when the yoke or head is positioned at a number of
predetermined angular positions in relation. Processing means are adapted
to control the moving head light fixture based on the actuator axel
position signal and the indication signal.
