Lighting controlled tour guide

The invention relates to a system for lighting controlled management of people in a limited region of space, particularly in a passenger transportation means, such as a railway vehicle, an aircraft or a ship. In particular, the invention provides a lighting device and a method of providing orientation information regarding the space region, a passenger transport means with such an illumination device, an electronic terminal for cooperation with the illumination device and for outputting based on the orientation information of the output data and a computer program to run on the mobile electronic relates terminal. The lighting device in this case has at least a light source and a modulation device for modulating the light emitted from the light source. The modulation device is configured to impose this data by modulating the light emitted from the light source, which contain a unique identifier of the illumination device or indicate a spatial position of the illumination system within the limited region of space. By means of the terminal, this modulated light can be received and recovered the imprinted thereon data and, together with reference data to be output at the terminal instructions to guide persons in the limited space region are processed.
