About light and illumination


 

Foyer


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 illumination level of 19,900 lm. Their light emission area measures almost 75 cm in diameter and consists of crystal glass with frosted white interior. Downlights are used in areas with a low ceiling height. Most of the light is aimed downwards directly onto the floor surface. The remaining light is directed into the room as a wide beam through thick-walled, partially frosted crystal glass. Here too, a degree of illuminance of 200 lx is reached at floor level.
