Being designed for the 26th Summer World University Games, the Universiade Sports Center in Shenzhen, China, is a building complex consisting of a stadium, a multifunctional hall, a swimming hall and an extensive landscape park.
As the day and night appearance of the sports buildings is dominated by a strict crystalline shape, the lighting design concept was focused on illuminating the translucent fabric evenly. Integrated within the steel structure, LED light lines provide a dimmable uniform backlight to vary the intensity. Thus, to save energy and to harmonize with the surrounding landscape throughout the night, the crystal shapes will shine brightly at twilight and will slowly die down until midnight. Although the RGB-LEDs can be adjusted in their colour, the normal operation is white.
The luminaires are constructed in such a way that the light sources of the sensitive facade lighting are not in the least visible, no matter from which angle they are seen. Otherwise, the clear structure would vanish, as the soft reflexion of the light would be superimposed by glaring light spots.
The connecting paths between the buildings are illuminated by plain, unobtrusive luminaires with warm colour temperatures and good colour rendering qualities. The luminaires are strictly constructed according to the geometry of the space, without scattered radiation towards close-by areas which otherwise would receive an unintended attraction. The creation of such ”calm spaces” which do not receive any direct radiation allows the visitors to relax their eyes by relying on their most sensible perception of soft light reflexions in pleasing darkness.
