A lamp mounting for mounting a number of lamps 8, 9 in a projector includes a rotatable turntable 2 mounted on a plate 1 in the projector housing. The turntable is normally held in position by a locking mechanism 3. The locking mechanism can be released by a manually operable member to allow the turntable to be rotated. Thus if one of the lamps 8, 9 burns out in operation another lamp can be brought into the operative position simply by rotation of the turntable 2. The turntable can be rotatable automatically by means of a spring 5. <IMAGE>
