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.
The illumination of large rooms is frequently effected using efficient downlights or pendant luminaires. In this example, both types are used. The distinctive pendant luminaires distribute soft light downwards from a height of 6 m. Visitors are received in the upwardly open ground floor with a degree of illuminance of 200 lx. These luminaires do not cause glare, in spite of the high...
