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.
