LED lighting draws power over Ethernet
Prolojik’s Lightmatrix lighting system combines LED lighting with power-over-Ethernet (PoE) technology and data cabling combined with established DALI features to provide a single lighting-control system. Analysis is said to have shown that a Lightmatrix system can be up to 11% more energy efficient than a mains-powered LED system by converting the mains supply to the required of LEDs more efficiently.
A demonstration version of Lightmatrix installed in Pricewaterhouse Cooper’s centre for social impact department in London shows that a 46% saving was achieved over a traditional approach.
Despite a 27% increase in average illuminance, a doubling in efficiency (103 lm/W compared to 51 lm/W) saw the installed load reduced by over 34%.
The Lightmatrix architecture is highly scalable and can be installed in new buildings or retrofitted, including as part of a phased upgrade.
