Energy-efficient lighting technologies are quickly pervading street-light deployments globally as municipalities seek to save money and utilities try to forestall energy shortages due to generation shortfalls. LED-based street lights have perhaps the greatest potential for energy savings because solid-state-lighting (SSL) technology is more amenable to adaptive controls than are induction or ceramic-metal-halide options. Controls will allow dimming of lights for even greater savings during off-peak hours. Network and control systems, such as Roam from Acuity Brands Controls, enable remote control and monitoring of street lights
utilizing a wireless mesh network.
Control networks, including the Roam Monitoring and Control system, aren’t confined to SSL installations. Indeed Roam came to the market before SSL did and Acuity has supplied the technology with many types of legacy lights for power monitoring, on-off control, and detecting failed lamps. Dimming is an additive feature that’s especially valuable with LED lights because the technology is amenable to dimming and delivering energy savings.
