Abstract: A lighting fixture having at least one internal processor and at least one fixed element to which controllable moving elements are rotatably fastened, one moving element having at least one light source that generates a beam of light. Information concerning positions of moving components in a lighting fixture is automatically achieved. Correct position indication at start up is obtained without moving the components to their end stops for finding set points for step motors by the provision of at least one absolute encoding device, which encoding device indicates the angular movement of a first input axel in relation to the encoding device, which absolute encoding device has a gearbox with a second internal axel, which first input axle drives a first toothed timing wheel, intermeshing with a second toothed timing wheel that rotates the second axel with a angular velocity different from the angular velocity of the first input axle.
