As Tridonic released on its website, it has accomplished a full illumination of the world famous Ulm Minster with innovative LED lighting. The Ulm Minster has the highest steeple in the world at 161.53 meters and an interior with very vast dimensions. Tridonic emphasizes that the new LED lighting remains discreetly in the background and allows the magnificent architecture to take the center stage. As the company furthermore explains, matching power supplies have been provided as well, ensuring an efficient operation of the luminaires and light control with many variants.
Vertically suspended 3.20 meter long LED tubes have been installed, some emitting light downwards and others emitting light to skywards. In this way a proper illumination of the church pews and ground as well as of the vault was achieved. Through the new LED installation, the vast dimensions of the area can be grasped which creates a formidable sense of space.
As Tridonic furthermore explained, the pendant LED luminaires form the entire lighting for aisles and nave. They were placed inconspicuously with a minimalist lamp design. The latter only could be achieved due to a separation of LED light sources and LED drivers. All lamps operate on SELV voltage which means no additional protection against hazards was required.
Tridonic’s drivers in this project work with 1-100% amplitude dimming and not with pulse width modulation (PWM), making it possible to locate the lamps’ control gear elements far away from the luminaires. Another advantage of 1-100% dimming is the fact that no electromagnetic compatibility (EMC) issues arise.
As Tridonic finally stated, in the Ulm Minster, the DALI protocol is used by the various integrated interfaces. Almost all of the LED lighting heads are dimmable and switchable. This enables various light scenarios to match the different uses of the church interior. Whether a small-scale church service or a concert in front of a packed hall, the lighting can be adjusted to meet the requirements of every occasion.sm.
