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: A headlight with a housing, in which light-generating and light-forming elements are arranged. The front part of the housing or a top, insert or attachment linked with the front part of the housing, is provided with at least two fixing claws for fixing accessory parts such as a diffuser, color film filter or wing elements that can be mounted on the light outlet of the headlight by the fixing claws. The fixing claws are characterized by one elastic element each or configure such an element on which an accessory part held by the fixing claw rests, thereby reducing undesired clattering noises.

Abstract: A device for connecting a first optical component to a second optical component, particularly for connecting the lamp housing of a spotlight to a lamp adapter. The device includes a connecting ring which has a first region which rotatably secures the connecting ring to the first optical component, and a second region which is axially distanced from the first region and enables the connecting ring to be connected to the second optical component. The second region includes coupling means, which engage with corresponding coupling means of the second optical component by rotating the connecting ring. The invention enables two optical components to be connected in a fast, simple manner.

Abstract: The invention relates to a headlight with a housing, in which light-generating and light-forming elements are arranged. The front part of the housing or a top, insert or attachment linked with the front part of the housing, is provided with at least two fixing claws for fixing accessory parts such as a diffuser, color film filter or wing elements that can be mounted on the light outlet of the headlight by means of the fixing claws. The fixing claws (510, 520, 530, 540) are characterized by one elastic element (7) each or configure such an element on which an accessory part held by the fixing claw (510, 520, 530, 540) rests, thereby reducing undesired clattering noises.

Abstract: The invention relates to a device for connecting a first optical component to a second optical component, particularly for connecting the lamp housing of a spotlight to a lamp adapter. Said inventive device comprises a connecting ring (2) which comprises a first region (22) which rotatably secures the connecting ring (2) to the first optical component (1), and a second region (21) which is axially distanced from the first region (22) and enables the connecting ring (2) to be connected to the second optical component part (3). Said second region (21) comprises coupling means (25), which engage with corresponding coupling means (31, 31a) of the second optical component (3) by rotating the connecting ring (1). The invention enables two optical components to be connected in a fast, simple manner.

Abstract: A lighting device comprises a discharge lamp (7) which is connected to a ballast and starting device (1) either directly or via an electric cable (4). Alternatively said discharge lamp (7) can be mechanically and electrically coupled to an external starting device (5) and electrically connected to the ballast and starting device (1) via a connecting cable (4).
