Advancing the capabilities of DALI lighting control

The first project to use Helvar’s Digidim router in a DALI system for lighting control is the Blekholmen premises in Stockholm
The first project in the world to use Helvar’s Digidim router for controlling lighting is the total refurbishment of the landmark Blekholmen premises in Stockholm, taking DALI (Digital Addressable Lighting Interface) to a new level. This vast building is home to the Swedish Post Office and required a high-tech lighting solution that was also flexible and user friendly. Electrical consultant PQR EL recognised the potential of the Digidim router to optimise the energy efficiency of the whole building. Project manager Bo Ericsson says, ‘We were looking for a total lighting solution with great flexibility for the entire premises. The long-term possibilities and advantages are endless, and we seem to be discovering new ones every day.’ The Digidim Router allows two DALI networks to be connected to one router. Only one control unit is required for lighting components (e.g. fluorescent tubes, dimmers and relays) and function units (such as keypads and occupancy sensors). 4000 routers can be connected to the same network, and half a million addresses can be connected to a single system. A PC connection is not required. Lars Wilsson, managing director of Helvar Sweden, says, ‘To implement the Digidim router in Blekholmen was truly a dream project, but also a challenge. Today’s installations need to be adapted to the project’s specific needs. Thanks to the new router’s ability to communicate individually with each fitting, we have met the architect’s every requirement.’
