Bluetooth transforms lighting control at Jewish museum

A WIRELESS Bluetooth mesh platform has transformed lighting control at a Jewish museum in Poland.

Managers of the Galicia Jewish Museum in Kraków were looking for ways to offer its visitors a deeper cultural experience.

After evaluating several options, the Museum’s directors decided it was time to modernise the obsolete lighting system.

The outdated lighting had become a growing problem, often preventing organisers from holding certain exhibitions, such as those including paper models and exhibits.

The directors also felt they needed full control over the lighting system.

The solution lay in Zumtobel’s Supersystem II track lighting installation controlled by a qualified Bluetooth mesh platform from Silvair.

The intuitive wireless approach minimised the amount of hardware and control cabling, while delivering a system that is flexible enough to recommission as needs and requirements change.

The first stage of this two-phase project saw Zumtobel install a multifunctional low voltage track system with 34 Supersystem II spotlights controlled via bmLINKs and a Litecom controller. The system was used to light the Museum’s temporary exhibition hall.

Zumtobel bmLINK is a wireless solution for DALI systems. It consists of senders (transmitters) and receivers, and can be connected to a central DALI controller such as Zumtobel’s Litecom, or used standalone.

The receivers provide numerous advantages, including no need for control cabling, minimal installation effort, and compatibility with new or existing systems.

At the Galicia Jewish Museum, each track is controlled by one bmLINK receiver and one bmLINK sender. Both are connected to the Litecom controller that controls the whole installation via DALI.

The system was ready for commissioning as soon as the electrical contractor had installed and powered up all DALI tracks and the Zumtobel Litecom central controller.

Before installation started, the installer had first set up a new project in the bmLINK Platform by uploading the layout with the lighting design, and created zones for each track. Once everything was installed and powered, he used the bmLINK Tool, a mobile app, to add all bmLINK devices to relevant zones.

The system was ready for commissioning as soon as the electrical contractor had installed and powered up all DALI tracks and the Zumtobel Litecom central controller.

This was followed by the automatic process of assigning DALI addresses initiated by the installer through the Litecom app.

Each address added to a single DALI group represented both a single track and a pair of bmLINK sender/receiver devices.

The final stage was to set up a number of scenes that would allow the Museum to modify the lighting settings for each exhibition.

This gives curators the flexibility to control the lighting and recall specific scenes based on their needs.

The chosen system will meet any challenges the Museum will face in the next few years, especially those related to the temporary exhibition hall.

The spotlights can be moved between tracks with no need for the system to be recommissioned.

In addition, the Silvair-based devices are future proof and can be updated over-the-air to add new functionality such as beacons, asset tracking and emergency lighting testing, or even monitoring of energy consumption and system faults.

Ultimately, the Galicia Jewish Museum now has a modern wireless lighting control solution that allows quick and effortless modification of settings and arrangement.

Most importantly, their staff can perform any modifications on their own when the need arises, without needing to bring in system installers or engineers - something that is always important for cash-squeezed cultural institutions.

The Museum is preparing for the second stage of the project, which will see the retrofit of the permanent exhibition space.
