The arrangement includes a casing (11), an LED (12) as light source, and a dioptric lens (13) as optics, for guiding the light emitted by the light source. The light source is adjustable in the casing relatively to the optics. The lens has a ring-shaped, or at least partially ring-shaped light output surface, whereby the light leaves the optics as a narrow strip, i.e. having a limited height. |
