Patent ID: 7654693

Claim:
A lighting fixture comprising at least one fixed element, to which fixed element controllable moving elements are rotating fastened, where one moving element comprises at least one light source, which light source generates a beam of light, which lighting fixture comprises at least one internal processor, wherein the lighting fixture comprises at least one absolute encoding devices, which encoding devices are indicating the angular movement of a first input axel in relation to the encoding device, which absolute encoding devices comprises a gearbox, which gearbox comprises a second internal axel, which first input axle is driving a first toothed timing wheel, which first toothed timing wheel is intermeshing with a second toothed timing wheel, which second toothed timing wheel rotates the second axel with a angular velocity different from the angular velocity of the first input axle wherein the first and second axles comprises magnets at the axle ends, which magnets generates a magnetic field mostly perpendicular to the longitudinal direction of the axles, which magnets each facing a sensor PCB which sensor PCB transmit the signals from the sensors to the internal processor.
