The department of coronary angiography at the Hospital of Helsingborg is situated in the centre of a large building complex and no natural light could pass into the rooms. During long Swedish winters, the personnel told us that entire weeks would pass, without them seeing the sun. How could we bring the healthy sunlight through the firewalls and into these rooms?
The Parans Solar Cables easily pass through firewalls and tight bends. As the roof was too far away, the solution was to place two systems on the East and West facades. One system brings the morning sun into the control room, and when the sun moves to the other side of the building, another system brings the light into a break room along the other wall. That way, both weather and time translate through the thin fibre cables.
- We actually turn off all electrical lighting when the sun is out, states one of the doctors.
They instantly see when the sun comes out of the clouds. The L1 Medium luminaires in the control room are placed so that light does not hit the computer screens and it gives a high and airy feel to the room. With already long cables, L3 Spotlights were mounted on the wall in the break room. That way some distance was won, and the light is bounced in the white ceiling to spread it. As this wall is a firewall, a wooden canal was built to match the hardwood flooring and wall panel, and the L3 spotlights were just snapped in place.
This installation uses two SP3-systems, with 20 and 24 meters (the latter was custom built) cabling. In the control room three L1 Medium luminaires. In the break room six L3 Spotlights.
