摘要： A spotlight having a variable angle of radiation includes a light source and a converging lens. The converging lens is the front lens of the spotlight. The front lens is eccentrically arranged such that the principal optical axis of the front lens is not coincident with the principal optical axis of the spotlight. For example, the principal optical axis of the front lens is parallel to and spaced from the principal optical axis of the spotlight by a predetermined distance.

摘要： A high-frequency movie camera has a sprocket wheel for supporting and transporting of a film. A rotating prism is positioned opposite to the perimeter of the sprocket wheel and is driven by the combination of a gear located on the sprocket wheel shaft and a pinion intermeshing with the gear and attached to the rotating prism shaft. In order to avoid moves caused by the necessary clearance between the gear and pinion, an electromagnetic brake is positioned on the rotating prism shaft, which is automatically controlled to limit the prism rotational speed.

摘要： A spotlight has an adjustable angle of radiation with modification of the angle of radiation being achieved in a manner other than by shading a beam path with a screen or mask. The spotlight has an interior light source (4) and a first lens (2) that is structured as a front lens. The first lens (2) is an aspherical lens.

摘要： An asymmetrical lamp has a main lens (2), a reflector (3) and at least one light source arranged between the reflector (3) and the main lens (2). In order to achieve a uniform illumination of all areas of an object, even when the lamp is not positioned on an axis extending 90.degree. to the object, the light source (1) and the reflector (3) are offset from an optical axis (6) of the main lens (2). The main axes (4, 5) of the light source (1) and the reflector (3) are, further, inclined to the optical axis (6) of the main lens (2). Preferably, the offset of the light source (1) and the reflector (3) relative to the optical axis (6) of the main lens (2), and the inclination of the main axes (4, 5) of the light source (1) and the reflector (3) to the optical axis (6) of the main lens (2), is adjustable so that the lamp can be optimally adjusted. In one embodiment an additional lens (7) is included between the light source and the main lens. In a further embodiment an eccentrically-positioned mirror (10, 11) is included at a surface of such an additional lens (7, '7") for reflecting light back toward the reflector.

摘要： A spotlight has a curved reflector (1, 1′) and a lamp (2, 2′) arranged inside a cavity formed by the reflector (1, 1′). The lamp (2, 2′) and the reflector (1, 1′) are movable relative to one another in a direction of a main optical axis of the spotlight. A converging lens (5) is arranged in front of the reflector (1, 1′) in a direction of light emission. A dispersive lens (6) is arranged between the reflector (1, 1′) and the converging lens (5).
