Abstract: A spotlight housing has a rear section in which a lamp socket is accommodated. The lamp projects forwardly through the back of a reflector. The lamp socket is mounted on a heat sink. A coil spring is interposed between the heat sink and the rear section of the follow spot housing. A screw threaded rod projects from the back of the heat sink, through the spring and through a large clearance opening in the rear section of the housing where it connects with a positioning knob. The knob is urged against the outside surface of the housing, which is spherically formed with a geometric center located near the access opening to the reflector. By shifting the knob along the surface, the lamp filament can be moved laterally in any direction relative to the reflector axis or focus. By rotating the knob, the rod length changes as the spring compresses and expands, thus moving the filament more or less into the reflector housing as the heat sink limits rotation.
