Moving head light fixture with yoke and head position encoding means

A light fixture comprising:

• a support structure;
• a rotatable structure rotatably connected to said support structure;
• said rotatable structure comprises at least one light source generating light;
• an actuator adapted to rotate said rotatable structure around a rotation axis;
• a position sensor providing at least one position signal indicative of the position of said rotatable structure in relation to said support structure;
• and
• a processing device adapted to control said actuator,
• wherein said position sensor comprises:
• a magnetic element attached to said rotatable structure, said magnetic element generating a magnetic field, said magnetic field is substantially perpendicular to said rotation axis, and
• a magnetic encoder fixed in relation to said rotation axis, said magnetic encoder provides an angular position signal indicative of the angular position of the a said rotatable structure in relation to said support structure.

A method of controlling a light fixture, said light fixture comprising a support structure and a rotatable structure rotatably connected to said support structure, said rotatable structure comprises at least one light source generating light, said method comprises the steps of:

• rotating said rotatable structure around a rotation axis using an actuator having a rotation axel;
• and
• indicating the angular position of said rotation axel,
• wherein said step of rotating said rotatable structure around said rotation axis using said actuator is based on said angular position of said rotation axel.
