On the basis of our empirical values and the suggestions of architects and planners, we have compiled room situations for which lighting design is frequently required. In the following, we shall present possible illumination solutions for these architectural situations. It goes without saying that all technical lighting standards are complied with. In some cases, the degree of illuminance proposed by us may even exceed the standard. For us, the aesthetics of light and a high level of visual comfort are important criteria for such decisions. At the same time, the form and the size of the luminaires must fit into the architectural surroundings. For example, we often recommend larger models if a structure has large dimensions – even if smaller luminaires with lower output would be enough. In such cases, the degree of illuminance can be reduced to a suitable level by means of a light control system.
Soft light is required in the staircase so that the steps do not cast any hard, irritating shadows. The light should also be glare-free. A combination of ceiling and wall luminaires is most suitable. In our example, landings on the individual floors are illuminated with light from the ceiling. The stairs themselves, on the other hand, are accompanied by wall luminaires. Here the luminaires should...
