Lighting Engineering

Quality and effect of lighting rest on the laws of the physics of light and on the physiological aspects of human sight. Light colour and light balance cumulate in a regular spatial illumination of the rail vehicle, supporting a feeling of wellbeing among the passengers.

At the beginning of the development, planning and manufacture of lighting systems for rail companies there is therefore a systematically data processing supported preliminary study, dependent on the tasks at hand. Numerous geometric parameters of the room to be illuminated, together with its reflective surfaces under defined conditions, are coupled with characteristics of the illuminating medium to calculate light scenarios, and an effective, energy-saving light concept evolved. An iterative process is used to create a virtual light plan, addressing the requirements of the individual train sections and in balance with the specific, standardised requirements with regard to light strength (general lighting, signal lighting, individual seat lighting, reading lighting).

This planning forms the scientific basis for the work of the designer and for the work of engineers.
