Energy legislation is a major factor in the growing number of connected lighting devices across the globe, writes Steve Montgomery
THE NEED to reduce energy consumption has led to an increase in the use of more energy-efficient lighting technologies such as compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs). Lighting systems – typically connected to the lights by a wired or wireless technology – can be implemented to optimise energy consumption as well as offering other features such as remote control. IMS Research’s recently published Connectivity Opportunities in Lighting Controlsprovides market forecasts to 2017 for the number of connected lighting devices and the adoption of both wired and wireless control technology in the three major regions of the Americas, EMEA and Asia- Pacific. It covers the key
sensors will be released in 2013. IMS Research projects DALI to be the most utilised lighting control protocol in lighting control systems, with shipments reaching over 90 million devices between 2010 and 2017.
RELIABLE OFFERING “Wired technologies such as DALI will remain dominant over the forecast period because of the number of companies currently offering them, the reliability they offer, as well as the limitations and problems that can arise from using a wireless solution,” adds Maddocks. “Another factor is the emergence of a DALI standard for sensors and ballasts in addition to the emergence of new systems to control DALI lighting, such as Control Network Solutions’ elitedali platform that allows

application areas of commercial, residential and street lighting. According to IMS Research
analyst Phillip Maddocks: “Energy legislation is one of the main factors pushing forward the adoption of lighting control systems in commercial buildings, particularly in the US where Title 24 and ASHRAE are in place. In other regions, such as Europe, although the same level of legislation does not exist, there is still a rise in the uptake of these systems, with owners investing in highly intelligent lighting control systems to reduce their buildings’ energy usage.”
DALI DOMINATES Currently, lighting control systems in commercial buildings use a range of wired and wireless technologies. The most prominent wired standard is DALI, although several companies offer their own proprietary versions that are not interoperable. However, it is expected that a standard for both ballasts and

communication, 802.15.4 technology is widely used; however, in the majority of cases, systems are proprietary. Daintree Networks is making progress promoting the ZigBee standard, and has recently begun a partnership with Philips to move the use of the standard forward. “Over the next few years, there will be the development of several ecosystems of devices using different technologies before a dominant standard emerges,” adds Maddocks. “With the support and the interoperability available as part of the ZigBee Light Link protocol, IMS Research believes that by 2017 ZigBee will have emerged as the main wireless technology being used in these systems, accounting for 38% of all RF-embedded bulbs and controllers shipped between 2010 and 2017.”
