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 general lighting in the swimming pool is effected by means of downlights, whose light offers safety on the surfaces around the pool. They also create lustrous effects on the surface of the water. The pool is illuminated by underwater floodlights. Unshielded luminaires with a high protection class are used on the walls of the hall to provide accents and to emit soft light.
The degree of illuminance must be distributed uniformly on the floor of the entire arena to ensure that neither horses nor riders are irritated in their sport by alternating light and dark areas. The indoor riding arena has dimensions of 70 x 30 m and is illuminated with downlights from the ceiling of the arena. The height of the roof ranges from 6 to 12 m. 200 lx is reached at floor level...
