World-beating lighting design
ENDURA light sources are fluorescent lamps with an extraordinarily long life-time of 60.000h, which is the equivalent of a permanent illumination of approx. 7 years.
ENDURA light sources do not contain any consumables. The discharge required for activating the light activation, does not occur – as is customary with conventional fluorescent lamps – between two electrodes but electrode-less in a closed “circle”.
The electrical power for the discharge is induced from outside by one or more magnetic ferrite ring cores with coils.

The roof of the underground station
An elegant curved, 8.000 square meter sized roof, made of light permeable, teflon-coated glass fiber tissue covers the entire station.
The underground roof is divided into 25 fields, which are profiled in a similar manner to the chambers of paragliders. The roof is supported by a tree-like construction. The luminaires with the ENDURA light sources were installed into the overall 14 support columns and they are invisible for passengers.

The rays of the luminaires strike the roof where they are reflected back down on to the platforms. The result is a homogeneous illumination, which lights up structures and creates the impression of space, providing a feeling of security even in the tightest of crushes.

Visualization
Visualization of the roof to assess the effect of different luminances on the roof and the resulting reflex glares on the platform. Visualization of the roof to emotionally verify the effects of the light. Analysis of different luminances on the roof and on the platform of wherever reflex glares occur.
