Abstract: The present invention relates to an atmosphere device (1) with a user interface (3) for controlling the setting of a lighting unit (2a) and/or a fragrance unit (2b) of the atmosphere device (1), thus determining the atmosphere conditions in a room. The user interlace (3) is based on a system comprising a detecting device (4) and transponders (6). By bringing the transponders (6) within the range of detection by the detecting device (4), the transponders (6) will send a return signal, which signal controls the settings of the atmosphere device (1). Each transponder (6) is programmed to control a particular color or a specific light intensity and/or a particular odor spectrum and intensity.

Abstract: A first road marking unit with a first base plate is provided with a first light source, and a second road-marking unit with a second base plate is provided with a second light source. A view angle of 0.1≦&agr;≦8° is formed between an interconnecting line, which interconnects the first and the second light sources, and an intersecting line which intersects the interconnecting line. In a view section where the view angle is 0.1≦&agr;≦8°, light beams originating from the first and the second light sources demonstrate a uniform overlap in the view section at a distance a≧40 m from the first light source. Preferably, the distance d between the first light source and the second light source lies in the range from 10 ≦d≦25 cm. The first and the second base plate of the road-marking units are integrated so as to form a base module.
