Christmas lighting concept for Karlsruhe city centre

The lighting concept for Karlsruhe combines the baroque city centre structure with modern lighting design. Colours, geometric shapes and interactive elements create a unique atmosphere that emphasises the fan layout and at the same time creates a dynamic, sustainable lighting experience.

Baroque fan layout as inspiration

The concept uses the characteristic axes and radial streets to create visual depth and emphasise the symmetry of the city.

Dynamic colour and temperature gradient

• Warm and cool colour tones alternate along the main axes, creating a subtle composition of light.
• A gentle transition between gold, red, blue and green reinforces the spatial orientation.

Street identity and ornamentation

• Each street is given its own lighting characteristics to provide orientation and enhance the cityscape.
• Light installations with fine ornamental structures pick up on historical elements.

Central vertical axis – Via Triumphalis

• The castle axis forms the visual centre with elegant, golden lighting.
• Light projections enhance the vertical effect and create a festive depth.
• The historical main axis is emphasised by arcs of light, symmetrical projections and a harmonious colour scheme.
• Warm gold and white tones convey a classic, festive atmosphere and emphasise the historical significance.

Horizontal axis: Kaiserstraße (thermodynamic gradient)

• A dynamic colour gradient from red (Europa-Platz) to gold (Marktplatz) to blue/green (Berliner Platz) visually guides visitors through the city.
• The colour temperatures create a flowing movement and highlight the central shopping street.

Radial streets (different identities) – radiating streets

• Each radial street is given its own colour and light identity that reflects its surroundings.
• Discreet points of light and interactive installations enliven the side streets and promote a pleasant atmosphere.

Conceptual integration with platonic bodies

• The five Platonic solids serve as the design basis for the lighting installations:
  • Tetrahedron (Europa-Platz): Moving points of light in warm red tones.
  • Cube (market square): Modular arcs of light in golden nuances.
  • Octahedron (Lammstraße): Interactive columns of light in green.
  • Dodecahedron (Schlossplatz): Projections of star patterns.
  • Icosahedron (Berliner Platz): Light waves in blue and turquoise.

Freestanding constructions

• Self-supporting lighting columns with geometric elements emphasise the cityscape.
• Flexible modules enable seasonal adjustments and efficient utilisation.

Interactive and ground-level installations

• Motion-dependent light sources create a playful experience for visitors.
• Projections and floor lights enhance the immersive effect of the concept.

Elevated but independent installations

• Light installations on roofs and façades provide additional spatial depth.
• Discreet fixtures prevent interference with the existing architecture.

Digital and projection-based solutions

• Projections on building surfaces and walkways create changeable light landscapes.
• Digital control enables flexible customisation and energy-efficient operation.

Modular festive furniture

• Integrated seating with lighting accents promotes quality of stay.
• Multifunctional elements such as benches and pavilions offer comfort and aesthetics.

Material and safety aspects

Safety concepts ensure smooth operation in heavily frequented areas.

Robust, weather-resistant materials ensure long-term use.

Sustainable LED technology reduces energy consumption and light pollution.
