Abstract: For changing a lamp in a lamphead, in particular a stage, studio, film and/or television lamphead, a cover component of the lamphead is opened by swivelling the cover component about a swivel axis. The swivel axis runs along a straight line which cuts the cover component in two points positioned at a distance apart from one another. In the case of a circular cover component, the two points are a secant of the cover component. The swivel axis preferably thereby runs near to the middle or even centrally or diametrically through the middle of the cover component. Preferably the straight line defining the swivel axis is vertical. The cover component does not have to be swivelled far to the side, upwards or downwards, but instead is swivelled partially into the case, whereby particularly in the case of limited space availability this leads to simplified handling of the lamphead, e.g. when the lamp is changed.
