Smart Streetlight

Networked street lighting system

LonMark International is a significant promoter of networked street lights using the ISO/IEC 14908 series of standards for networked control.  Companies offering products based on this international standard are encouraged to adopt Interoperability Guidelines from LonMark International to ensure their products are interoperable with those offered by other companies.  For municipalities, specifying products certified by LonMark International provides a selection of products and solutions offered by a variety of suppliers, reducing the cost of installing and supporting systems over their lifetime.

  • Reduced energy consumption by up to 40%;
  • Lower maintenance costs by up to 50%;
  • Remote monitoring and control;
  • Diagnostic reporting to identify irregular lamp behavior, individual lamp failure, and lamp temperature;
  • On/off control of individual lamps or segments;
  • Ability to remotely adjust light levels based on time, traffic, weather, season;
  • Integration with police and emergency services for lamp flashing;
  • Increase driver, pedestrian, and resident safety;
  • Serve as an infrastructure for new services such as traffic sensing.

Why open?

Network streetlight solutions are more than a collection of subsystems or segments supplied by different suppliers that are connected together at some enterprise layer. They should be based on industry standards, such as the ISO/IEC 14908 control networking standards. Specifying a standards-based architecture such as ISO/IEC 14908 allows the procurement agent to purchase best-of-breed lamps, ballasts, controllers, sensors, data concentrators and other components from multiple suppliers. This interoperable framework creates a durable competitive environment whereby any part of the system can be sourced from a different supplier. This prevents vendor lock-in, since no single component will force owners into a proprietary, single-vendor solution, with a single source for replacement parts and a single source for maintenance and support. With a well-structured standards-based system, all of the proprietary hooks are removed, leaving the customer with a wide variety of options.

LonMark International is the only organization that enables a standards-based solution for multi-vendor networked streetlight solutions. The ISO/IEC 14908 control networking standard has played a pivotal role in transforming several industries. From commercial buildings, public transportation systems, industrial plants to home automation, electricity metering infrastructure and Olympic venues; applications built on the LonMark interoperability standard are everywhere. Millions of devices are installed worldwide in homes, buildings, and smart grid systems.

Comparison to proprietary systems

More than 50 suppliers have developed their own proprietary technology to communicate between their light controllers and their segment controllers or gateways. This approach is very expensive and inefficient given all of the elements required to create a total system. By using standards-based systems every manufacturer benefits from multiple sources of supply of standard components, standardized tools and common software.

The LonMark interoperability standard provides an open framework from which competing suppliers can build compatible products. Using a standardized profile, the attribute of every supplier’s product is published, making it easy to install and maintain using standardized software tools and enterprise front-ends. Products conforming to the standard are tested and certified by LonMark International to verify that they are compatible. Products passing the certification process carry the distinctive LonMark logo. Over the past 25 years, LonMark International has tested and certified over 900 products that conform to its interoperability standard.
