with LonWorks® Technology

The Customer City of Oslo Oslo, Norway The Integrators Kongsberg Analogic AS Kongsberg, Norway Philips Lighting Oslo, Norway The Challenge The city of Oslo needed a street lighting solution to satisfy European and worldwide directives to reduce energy use and carbon dioxide emissions. The Norwegian capital also wanted to lower streetlight operating costs, ensure driver and pedestrian safety, and allow remote monitoring and control.

The Solution

As part of its new intelligent outdoor lighting system, Oslo is replacing mechanical ballasts in its 55,000 streetlights with electronic ballasts that communicate over existing power lines using Echelon’s power line technology. The system remotely monitors and controls the lights, dimming them based on traffic, weather, and available light. It also analyzes lamp behavior and identifies lamp failures.
