Abstract: A fastening system for fastening a lamp has at least one electrical source of radiant light, in place in a light system. Part of the lamp projects into an opening in the light system and is releasably connected thereto. At least three lugs take the form of electrical contacts and reference points in this case, and the areas of contact of the lug and lug-receptacle system are so arranged that, in the end position, their mating areas can be caused to mate in positive inter-engagement by an axially applied force.

Abstract: In an arrangement for displaying images on a projection screen, which arrangement includes a laser, which emits a laser beam, and a deflecting device, which is provided for deflecting the laser beam, and an image-generating device which is connected to a controlling device for controlling the laser and the deflecting means. The image-generating device is switchable in two operating modes, the first operating mode being the standard operating mode for projecting, and the second being an operating mode in which the laser radiation is harmless to a person disposed in the region to which the laser has access.
