Customer Success Story

The company "Licht & Raum" faced the challenge of equipping a new office building with a modern and energy-efficient lighting system. The goal was to find a flexible and user-friendly solution that meets the diverse requirements of the various work areas. After thorough research and consultation, the company decided to use Lunatone’s DALI-2 PD 3-25W universal dimmers. The decision to choose the DALI-2 PD dimmers was based on several factors: The ability to use both leading-edge and trailing-edge phase dimming allowed integration of different types of lamps, including LED retrofit lamps. The automatic load detection ensured that the dimmers automatically recognised and adjusted to the connected loads, significantly simplifying installation and configuration. Precise lighting control optimised energy consumption and reduced operating costs. The dimmers were fully compatible with the building’s existing DALI system, enabling seamless integration. The simple installation and configuration allowed the technical team to commission the system quickly and efficiently.

In addition to the 25 W dimmers, "Licht & Raum" also chose to use the larger sibling model, the DALI-2 PD 300W universal dimmer. This model offers the same flexibility and automatic load detection but can control a higher load of up to 300 W. This was particularly useful in areas of the building requiring stronger lighting, such as conference rooms and reception areas. The combination of both dimmer models enabled optimal adaptation of the lighting to the specific requirements of the different rooms.

To enable time-controlled and remote lighting control, additional Lunatone components were integrated. The DALI-2 RTC sequencer with real-time clock and timer function allowed automatic, time-based execution of command sequences. This was especially practical for controlling lighting at specific times of day, such as automatically switching the lights on in the morning and off in the evening. For remote control, the DALI-2 IoT4 gateway was used, providing an interface between the DALI system and the building’s LAN network. This enabled employees to control the lighting via an app or web interface from their computers or mobile devices.

After installing the DALI-2 PD dimmers and additional control components, "Licht & Raum" noted several benefits: Employees benefited from individually adjustable lighting that could be adapted according to needs and time of day. This led to an improved working atmosphere and higher productivity. Energy-efficient lighting control significantly reduced operating costs. The investment in the DALI-2 PD dimmers paid off within a short period. The company was able to reduce its ecological footprint by optimising energy consumption, thus contributing to environmental protection. The flexibility and scalability of the DALI system allowed easy expansion or adjustment of the lighting system as needed, making the building future-proof. Overall, the decision to use Lunatone’s DALI-2 PD 3-25W and 300W universal dimmers was an excellent choice for "Licht & Raum". The dimmers offered the necessary flexibility, energy efficiency, and user-friendliness to meet the requirements of the modern office building. The successful implementation of the system demonstrated how intelligent lighting solutions can help improve work environments while saving costs.
