Abstract
A device for depicting a linear optical marking () in a room, including a housing () with a light source () that emits the light along an optical axis (), as well as a lens () that both reflects the light and allows it to pass through, that is arranged in front of the light source and through which the optical axis extends. In order to be able to illuminate an area of the room with simple design measures, i.e. depict lines, which cannot be captured with a direct beam path of the light source it is suggested that the lens () have a trough-shaped geometry with a longitudinal axis that extends transversely to the optical axis () of the light source (), that the lens have a first section extending on the light source side, and that the first section reflect light in the direction of the light source all the way into an area that extends beneath, to the side of, or above the light source as a function of the course of the longitudinal axis to the lens and into the area of the room facing away from the light source in terms of the light source.
