Intelligent lighting control for comfort and energy savings

The mid-sized electrical engineering company B.E.G. (Brück Electronic GmbH), based in Lindlar in the Oberberg district, has been family-owned since 1975. Its nearly 50-year company history began with the production of simple emergency lights. In 1986, motion and presence detectors were added, followed by various sensors and actuators, which remain a significant part of the product portfolio today. B.E.G. is now on the path to becoming one of the leading providers of building automation. With 14 foreign subsidiaries and over 260 employees worldwide, B.E.G. offers close customer proximity globally and is known for its broad product and accessory range, flexible, customer-specific product development, and application-oriented expert advice for connected products.

Planning configuration data is securely transmitted over the internet to the LUXONET® field bus controller installed on-site, which is identified via serial number or QR code. Depending on project size, the necessary DALI gateways are connected. The DALI gateway performs a line scan and automatically integrates existing DALI devices into the LUXONET® system. The system integrator can check remotely if all sensors, switches, and lights are correctly installed, minimizing costly site visits. On-site, only the binding is required, where the planner uses a smartphone or tablet to make lights blink for identification and confirm proper addressing, making the process more efficient.

A further advancement in the LUXONET® controller is biodynamic lighting, also known as Human Centric Lighting (HCL). This technology mimics natural sunlight by continuously adjusting color temperature and light intensity throughout the day. Studies show that biodynamic lighting can increase employee productivity and well-being.

During the development phase, a particular focus was placed on data security, as this is critical for public building tenders. Synchronization with the controller is encrypted via MQTTS. Internet connectivity can be achieved through the local network or a standalone LTE gateway. Additionally, it is crucial that the lighting system functions offline after installation, ensuring functionality in emergencies. Configuration parameters are always available in the cloud, allowing for easy restoration of the controller after a hardware failure.
