Abstract
An apparatus for focusing a light flux, includes a light source, and a light-conducting system which guides light radiating from the light source along a first light-conducting passageway oriented in a direction of the path of light, and along a second light-conducting passageway extending at an angle to the first light-conducting passageway. The light conducting system includes a first optical lens which is positioned at an entry side into the first light-conducting passageway, a deflector which is positioned at an exit side of the first light-conducting passageway for deflecting visible light into the second light-conducting passageway, and an optical assembly which is disposed in the second light-conducting passageway. The optical assembly is formed by an dimming disk, adjustable with respect to the second light-conducting passageway, for selective control of light intensity of the visible radiation, and a second optical lens for focusing the deflected radiation.
