Lighting in Design February-March 2016

Customer-specific lighting solution As part of a lighting refurbishment, Osram Lighting Solutions supplied an individual and highly efficient lighting solution for the offices and conference rooms of the Bavarian State Medical Board in Munich, Germany. With help of state-of-the-art multi-sensors and the Dali Eco control system, suspended LED luminaires are now controlled ac- cording to daylight, occupancy and movement.This saves up to 65% in energy each year.

cupied, lighting is dimmed down to 10% after 15 minutes and switches off completely after a further 10 minutes. The Dali Eco multifunctional light management system is a simple plug & play solution, and com- missioning is carried out using remote control. A completely automatic nominal value setting is set with the press of a button, based on the illuminance level specified by the lighting design. Intelligent and efficient light management is becoming increasingly important – occupational safety, productivity, concentration and well-being are significantly linked to lighting. In addition, cost consciousness and the desire for environmentally protective and intelligent technology are increasing. Christian Remmelberger-König, Application Engineer at Osram Lighting Solutions, explains: "We've devel- oped this modular sensor and control kit to meet a diverse range of tasks. It's only with a combination of high resolution sensors, professional control technology and premium luminaires that complete, customer-specific lighting solutions can be achieved."

The Bavarian State Medical Board with head- quarters in Munich is one of 17 German medical Chambers. As the legislative professional associa- tion for 75 000 Bavarian doctors, it represents their occupational interests, promotes medical training and creates social facilities for doctors and their dependents.The office and conference rooms were upgraded in 2015 and were equipped with around 700Arktika suspended LED luminaires.The ultra-flat, computer screen-compliant designer luminaires are suspended on two thin wires, and create a pleasant ambience thanks to a combination of direct and indi- rect light components.The luminaires are combined with state-of-the-art sensor and control technology. Multi-sensors and the Dali Eco control system implement presence and motion detection as well as control of light according to levels of daylight, and users can control the luminaires individually using push-buttons (for on/off and dimming). Passive infrared PR3 sensors are installed in the ceiling. They detect the presence of people at workstations and enable motion detection in the room. Control is implemented in semi-automatic mode. If an employee enters the room in the morn- ing he or she presses the button to activate the lighting. The system adds the required quantity of artificial lighting according to the ingress of daylight until an illuminance level of 500 lux is achieved, as valid for office spaces. If the room becomes unoc-
