Kultur- und Kongresszentrum Liederhalle Stuttgart

Over 1300 meters of linear FLASHAAR® LED lights illuminate the newly renovated congress area of ​​the Liederhalle Stuttgart culture and congress center.

The Liederhalle Cultural and Convention Center is located in the heart of Stuttgart and is one of Germany's leading concert halls. While the cultural center has hosted major orchestras such as the Vienna Philharmonic and music greats such as Jimi Hendrix, the so-called Hegel Complex is a popular venue for conferences, meetings, and trade fairs.
After an 18-month renovation of the convention center, the fire protection, building and network technology, as well as the stage and event technology, are now state-of-the-art. In the spirit of sustainability, around 4,500 energy-efficient LED luminaires were installed for the audience lighting, including numerous luminaires from FLASHAAR ®.

Lighting concept with a blue ceiling colour: a major challenge for Gerd Pfarré's lighting planner was to make the extensive foyer area with its complex ceiling structure more inviting. They decided to paint the previously white ceiling a rich dark blue, adding calm and elegance to the space. Since the foyer is used for events, the lighting designers paid attention to a balanced distribution of light. They also optically brightened the room edges in order to sharpen their effect in the room. The used LED light lines of the type NauticProfil Nova-5 trace the striking ceiling openings with neutral white light. Due to the white cover used, no points of light can be seen and the line of light appears homogeneous throughout. The generous feeling of space is additionally supported by the light reflections of the floor.

Hegel Hall – Custom luminaires highlight the acoustic sails: The Hegel Hall is the central focal point of the conference center. It seats approximately 1,900 visitors and has the floor plan of an irregular heptagon. The hall owes its excellent acoustics to a sophisticated sound system. Since no wall runs parallel to the opposite wall, sound spreads diffusely – an advantage for spoken word. Daylight falls through the striking skylight dome, which is divided into an upper and lower volume by suspended glass sails. This ensures brightness and perfect acoustics for all seats and is certainly the most striking component in the hall. The glass sails are assigned light structures that create brilliance behind the glass. It was important to the lighting planners to maintain this light image after the renovation. To achieve this, they used custom luminaires from FLASHAAR based on the NauticProfil Focus and achieving a wide light point spacing.

Hegel Hall – Linear grazing light for the walls: FLASHAAR illuminate the walls along the Hegel Hall . The NauticProfil system used is ideal, as it creates long, easy-to-install light lines with just a few feeds. To largely conceal the direct view of the light source, the luminaires were mounted in a narrow, deep trench. Their grazing light visually highlights the walls and provides indirect illumination of the room. Various light colors are used: 3000°K warm white light sweeps along the sides of the hall's walls. 4000°K neutral white light is used on the exterior walls. 30° linear lenses are used for precise light control, with the frosted surface creating the most homogenous light line possible. The LED luminaires can be continuously dimmed via DALI.

Foyer area – Linear pendant luminaire: To illuminate the ceiling trench, the lighting designers used a new FLASHAAR luminaire – the H2flex. Its flexible design allows for countless lighting solutions and serves the lighting designer as a modular system for creating a space. The resulting black anodized pendant luminaire is almost 30 meters long and follows the winding course of the ceiling trench. Equipped with high-intensity NauticProfil Nova-5 luminaire inserts, its neutral white light serves as part of the ambient lighting. The converters and dimmers are installed externally at the customer's request to simplify maintenance.

Restrooms – Cove Lighting: In addition to these central lighting elements in the Hegel Hall and foyer area, FLASHAAR NauticProfil light lines were also used to provide functional yet elegant lighting in the restrooms. Built into a ceiling cove, the luminaires are invisible to the viewer. The indirect light serves as ambient lighting and creates a pleasantly relaxed atmosphere.
