Light According to Needs

Osram supplies an intelligent lighting solution for offices at the Bavarian State Medical Board.

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 according to daylight, occupancy and movement. This saves up to 65% in energy each year.

The Bavarian State Medical Board with headquarters in Munich is one of 17 German medical Chambers. As the legislative professional association for 75,000 Bavarian doctors, it represents their occupational interests, promotes medical training and creates social facilities for doctors and their dependants. The office and conference rooms were upgraded in 2015 and were equipped with around 700 Arktika suspended LED luminaires. The ultra-flat, computer screen-compliant designer luminaires float by two thin wires, and create highly pleasant room atmospheres thanks to a combination of direct and indirect light components. The luminaires were also 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 additionally control the luminaires individually using push-buttons (for on/off and dimming).

Passive infrared PR3 sensors are installed in the ceiling, and although hardly recognisable for observers still feature high performance. The sensors detect the presence of people at workstations and enables motion detection in the room. Control is implemented in semi-automatic mode. If an employee enters the room in the morning he 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 nobody is in the room any more, 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 commissioning can be simply and conveniently carried out using a 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 the lighting situation. Simultaneously, a cost consciousness and the desire for environmentally protective and intelligent technology is increasing. Christian Remmelberger-König, Application Engineer at OSRAM Lighting Solutions, explains: "We've developed this modular sensor and control kit to meet this very 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."
