The Internet of Things (IoT) has become the talk of technologists everywhere, on every product level imaginable. Lighting is no exception. Understanding why this is such an energetic field requires thinking beyond conventional control and connectivity models. The integration of smart features opens the door to intelligent utilization of data and energy that cannot be achieved using closed, localized technologies that cannot be accessed beyond their limited utilitarian functionality.
In August 2018, the California Lighting Technology Center (CLTC) published a best practices guide for designing daylight harvesting lighting control systems. Titled Daylight Harvesting for Commercial Buildings Guide, it focuses on compliance with California’s Title 24 energy code, though it has broad application.
Craig DiLouie, LC, CLCP recently had the opportunity to interview Jonathan Cartrette, Systems Architect, Wattstopper/Legrand for an article that will be published in 2019 for ELECTRICAL CONTRACTOR. The topic? Lighting and cybersecurity.
In September, California passed SB-327, a cybersecurity law that will affect manufacturers of Internet of Things (IoT) and operational technology (OT) devices.
This article at Eaton’s THE SOURCE website provides an insightful look at how connected lighting can facilitate space optimization.
In August 2018, the DesignLights Consortium (DLC) released Energy Savings Potential of DLC Commercial Lighting and Networked Lighting Controls, which projects energy savings for LED commercial lighting and networked lighting controls. The report makes a case that to continue getting big energy savings from lighting for another decade, utility rebate program administrators should transition to supporting LED luminaires and networked controls.
In this guest post, LCA contributor Steve Mesh describes the “non-energy benefits” of connected lighting, which can add extraordinary value far beyond energy savings.
“As the lighting industry attempts to morph from its conventional role of illumination and become more of a provider of smart networks that collect data through chips and sensors embedded in the lighting infrastructure, it should focus its sales efforts on IT groups rather than on the customary facilities departments,” Mark Halper writes for LEDs Magazine.
“While the majority of installations today are distributed high voltage (between 110V and 347V), the emergence of solid-state lighting technology has brought into question whether this is the most practical and efficient way to feed future lighting systems … In general illumination application, there are currently two core approaches to operating luminaires directly from low voltage DC power. Emerge Alliance 24VDC distributed, and Power over Ethernet (PoE). The two approaches employ distinctly different control approaches.”
Networked control and connected luminaire manufacturers are now promoting their products as “IoT enabled.” This means when the IoT does arrive, the lighting system will stand ready to play a part in it without significant additional cost. The converse may also be regarded as true, which is without connected lighting, any new LED lighting may instantly become obsolete after installation.
