Abstract
A lighting fixture having at least one fixed element, to which fixed element controllable moving elements are rotatingly fastened, where one moving element has at least one light source. To automatically receive information concerning the orientation of lighting fixture and to achieve feed-forward regulation of cooling in the lighting unit the lighting fixture has an orientation sensor as the at least one the fixed element, which orientation sensor detects at least 3 orthogonal axes and transmits orientation signals to an internal processor in the lighting fixture, which processor calculates the actual orientation of the fixed elements. As a result, a computer that controls the lightning fixture knows the actual position of each component in the lightning fixture.
