Abstract: A device for adjusting an optical tube, which is disposed in a housing of a spotlight or optical device and which is guided in the housing in the direction of the optical axis of the spotlight or optical device is provided. An adjustment drive, an operating element and a brake device is disposed between the tube and the housing, which with the adjustment drive not activated connects the tube to the housing in a non-positive locking and/or positive-locking manner and which on activation of the adjustment drive releases the connection between the tube and the housing and enables adjustment of the tube along the optical axis of the spotlight or optical device.

Abstract: A lamp housing which contains an accommodating apparatus for a burner or a lamp with a glass vessel, a lamp base and contact pins for supplying current, and a lampholder with sockets for connection to the contact pins, is provided. The accommodating apparatus containing clamping jaws, which can be connected to the lamp base in a force-fitting and/or interlocking manner, engage at least partially around the lamp base, are articulated, via lever arms, on the lamp housing or a lampholder mount, which is fixed to the housing and is connected to the lamp housing, and can be adjusted by means of an adjusting device, which has at least one adjusting element, which is arranged between the lever arms and pushes the lever arms apart from one another for opening the clamping jaws into an opening position, in which the lamp base is released, and brings the lever arms together for closing the clamping jaws into a locking position, in which the lamp base is fixed.

Abstract: An apparatus for accommodating and making electrical contact with a luminous means, which contains a glass vessel, a luminous means base and contact pins for supplying power, in a spotlight, which contains a luminous means holder for accommodating the luminous means base with plug-type sockets for accommodating the contact pins of the luminous means, is provided. The luminous means holder has a device for monitoring the connection between the luminous means base and the luminous means holder. The monitoring device comprises a device for detecting the relative position of at least one part of the luminous means base in relation to the luminous means holder when the luminous means base is inserted into the luminous holder.
