The lighting performs the tide levels of the river Rhine as a visible sign. The sensor system performs – white – for standard levels and – red – for high tide with yellow and orange in between. The more the crystal-like backlit cube is filled with red light, the higher is the tide. The façade lighting is made of an extruded profile as a trimless light line RGB-LED IP 67 to be attached at the façade carriers and is throughwired in IP 67. The lightlines are adapted to modularly uniforn distances between the LEDs for a maximum uniformity of light possible. The converters for feed in IP67 at 24V DC, are prepared for EUTRAC®DALI/-EIB control.
