ENERGISING WHITE LIGHT

The Löhr Centre in Koblenz creates atmosphere with tunable white

The Löhr Centre in Koblenz is one of the largest inner-city shopping centres in the Rhineland Palatinate. It was renovated by ECE as it had been in operation for over 30 years. A fundamental element of the refurbishment was a comprehensive lighting and colour concept.

LARGE PROJECT, NARROW TIMEFRAME

An initial draft of the lighting design for the Löhr Centre, which opened in 1984, was created in 2014, when partial modernisation of the 32,000 sqm sales area was planned. In March 2016, ECE decided to renovate all three floors, where around 130 shops are located today. The lighting plan had to be completely revised by the time of reopening in spring 2017 and finished while the shopping centre was open for business.

THREE ATRIUMS PROVIDE STRUCTURE

As part of the relaunch, a new interior design was chosen that divided the mall into three sections: “The Lobby” was depicted in energising blue, green and yellow, “The Boutique” in stimulating red, blue purple and turquoise, “The Collection”, with its floor-to-ceiling bookcase, as a highlight in warm red, purple and yellow.

COLOUR ACCENTS USING TUNABLE WHITE

The lighting concept picks up from these colour schemes in the form of decorative, geometrical light panels, which create an impressive ceiling design. Coloured film serves as filters, where the colour effect varies depending on the time of day. Distribution of the high-performance LEDs in a dense 10 cm grid ensures that the luminous effect is extremely homogeneous. In the daytime, the general lighting has high luminous intensity with a cool colour temperature of 4000 K, the decorative ceiling lights create a strong contrast with warm light up to 2200 K. In a night-time setting with subtle general light, the light panels produce a strong contrast with 4000 K.

LIGHTING MOODS OVER THE COURSE OF THE DAY

The lighting concept is based on energy-efficient LED technology with tunable white, four lighting moods are created by using luminous intensity and colour temperature. These moods are produced using day/night lights with a special Fresnel lens system, which distributes direct and indirect light to the optimum. Perfectly shielded lights are built into a streamlined LED strip system that is just 4 cm wide, so that accented light appears like patches of sunlight, which are only perceived unconsciously. An exterior sensor captures the natural light values; the controls operate according to an automatic programme.

QUALITY LEISURE SPACE

Additional mood spots provide light in the seating and display areas. Special pendant lights with metal grid shades, up to 4 m in diameter and 3 m in height, fill the mall visually and accentuate the welcoming character of the Löhr Centre.
