Abstract (en)
[origin: EP0402845A2] A spotlight with infinitely variable light intensity contains a reflector (10) for generating a light bundle emanating from a light source (18). A stop (22) is arranged in the beam path of the light bundle. In order to vary the illumination of the stop, a positioning device (28...36) for the relative adjustment of the light source (18) along the optical axis (16) of the spotlight is provided for the purpose of varying the used cross-section of the light bundle in the plane of the stop (22). <IMAGE>
