Lighting Legislation: GE LEDs and Lamps Enlighten the Parliament of Liechtenstein
When it became evident that the assembly hall required the placement of cameras and microphones for online coverage, the large nine-meter diameter ring-shaped chandelier proved to be a superior solution for inconspicuously integrating the necessary technical modules. The countless wires for the 36 compact fluorescent lamps, 72 halogen lamps, eight microphones, and four dome cameras had to be grouped into 12 bundles of cables. Without visible canopies or attachments, the profiles disappear between the bricks of the roof slope. In addition to the chandelier, four downlights with GE 70-watt ConstantColor® CMH® T6 3000 K ceramic metal halide lamps create discreet general illumination. They are recessed in the roof ridge and can be lowered by means of simple rope winches.
“The assembly hall called for sufficient horizontal illuminance levels on the table and uniform vertical illuminance levels for shadow-free facial recognition,” said Mary Beth Gotti, manager of the GE Lighting & Electrical Institute. “GE, therefore, fitted the chandelier with directional and diffuse lighting components: GE 35-watt halogen T4 12-volt lamps and GE 18-watt Biax® L 3000 K fluorescent lamps.”
To retain its homogeneous appearance, both light sources are concealed behind a bronze fabric upholstered to a frame, forming the bottom edge of the luminaire ring. The individual fabric panels can be removed for maintenance.
Other interior lighting design features include GE Tetra® Contour LED lighting integrated into the main stairs and precisely fitted GE 28-watt T5 Ecolux® fluorescent lamps mounted above timber ceiling coffers in other functional and common rooms within the complex.
On the exterior, the luminous intensities of the High House and Long House are coordinated to form a harmonious ensemble. The High House emanates light from within. The Long House is defined by the brise soleil, positioned in front of the window facade to control incident solar radiation. Lit up by in-grade luminaires with GE 35-watt CMH 3000 K ceramic metal halide lamps, a distinctive rhythmic contrast of light and shadow emerges.
This lighting project is among several recognized during the 2008 GE Edison Awards held in May 2009.
