New street lighting system can be linked to traffic flow

A UK company has launched enhancements to its street lighting control system that includes dimming programs that are linked to traffic flow. Unveiling its new products at Illuminating Engineering Society’s (IES) Street and Area Lighting Conference in Tennessee, Telensa has enhanced its market-leading PLANet SmartGrid street light control system by adding an on-board GPS module and the new NEMA 7-pin connector to its telecell options. The company has also demonstrated a raft of other new features for its PLANet system (Public Lighting Active Network) street lighting central management system (CMS), including adaptive lighting controls for traffic flow monitoring, an enhanced user interface, built-in constant light output, multiple dimming levels, override functionality and a new-look, low-profile telecell node for better aesthetics.

Telensa’s new low profile telecell unit features the industry-standard NEMA ANSI C136.41 7-pin connector, providing simplified installation and a standardized dimming capability for compatibility with multiple lighting vendors, with the extra pins providing a level of future proofing. The self-contained, fully configurable and programmable telecell control unit now puts itself on the map due to an on-board GPS. It also offers on-board light sensor and astronomical clock, in addition to the radio control processor, street light controller, monitoring circuitry and a ‘revenue grade’ electricity metering chip. Responding to the requirement for dynamic dimming, the company has added adaptive lighting to its PLANet system to allow the implementation of dimming programs linked to traffic flow. This has been successfully trialed in San Francisco by the city’s Public Utilities Commission.

Telensa’s CEO, Will Gibson, explained, “As energy costs soar and street lighting engineers embrace the use of LED technology, we want to show that our field proven low power ultra-narrow band (UNB) wireless control system delivers the features the market requires and offers considerable savings of between 20-30% over and above the savings made from switching to LEDs. It is now possible to link the outputs from traffic detection systems directly to our CMS and dynamically control the lighting based on real-time traffic flow. With talk of ‘the Internet of Things’ all the rage, having our CMS in place for street lighting provides an excellent platform to deliver further savings and services as new applications are added. With a track record of large scale system deployment of more than 100,000 lights and with systems in place across the world, we are continuing to expand our market-leading position with successful installations and additional new products and features.”
