THE WORLD WIDE WEB CONNECTS 10 BILLION DEVICES and counting into a global network. Any net-
work-enabled device can establish a link to the internet, raising the potential to join building systems appliances and more.
In lighting, the development of intelligent lighting controls and digital communication architectures allowed networkable
lighting. The miniaturization of microprocessors enabled intelligence to be embedded in lamps and luminaires. Digital com-
munication enabled remote programming and the collection of data used for energy analysis and maintenance. These controls
are inherently compatible with light-emitting diode (LED) lighting, which is also digital.
More recently, capabilities such as the cloud, coupled with growing interest in intelligent building operation and Big Data,
have accelerated the development of the Industrial Internet of Things (IIo T). By deploying intelligence throughout a building,
it becomes much more responsive. Sensors feed responsiveness while generating valuable data.
Lighting will play a part in the IIo T, but it has another valuable role. The conversion of traditional lighting to LEDs presents
an opportunity to use LED luminaires as infrastructure for IIo T delivery.
The IIo T
The IIo T concept is still seeking a firm definition, but we can
loosely define it as a network of programmable, intelligent,
sensing, interoperable devices applied to a large built application, such as a facility, campus or city. Each device is uniquely
addressable within the network, which is connected to the
internet by an internet protocol (IP) gateway. The network
self-optimizes its performance while generating analytics.
said Brian Donlon, vice president of sales, Lutron Electronics
Co. Inc., Coopersburg, Pa. “However, the IIo T will make inte-
gration easier and more cost-effective, facilitating seamless
interoperability between fixed devices, mobile devices and
external systems to make spaces and buildings smarter.”
Applications are far-reaching, leading to some staggering
forecasts. Tech giant Cisco predicts 50 billion devices will
be connected by 2020, while Intel has predicted 200 billion.
McKinsey forecasts, in 2025, the IIo T’s global market value will
reach $70–$105 billion in office buildings, $410 billion to $1.2
trillion in retail buildings, $1.2–$3.7 trillion in industrial build-
ings and $930 billion to $1.7 trillion in cities.
For example, a lighting control system could use sensors to
detect occupancy or the presence of a smartphone and then
pass that data to other building systems for response. Strengthening the connections between building systems can result in
greater energy cost savings.
The internet of lighting
Using the IIo T’s informal definition above, it’s already being
implemented for some building systems. Centralized intelligent
lighting control systems consist of uniquely addressable, intelligent control points networked using radio waves or digital
low-voltage wiring. The system senses and directs programmable responses to changes in the environment. It is also capable
of monitoring and generating energy-consumption reports.
Some systems extend sensing to collect additional data about
building space occupancy and temperature.
“Intelligent controls are a first step to energy-reduction
schemes, including simple switching, on/off time schedules,
occupancy sensing and daylight harvesting,” said Jason Brown,
manager of strategic solutions, Current, powered by GE, Boston.
“Many of these controls can also be synced with a building-management system to take functionality to the next level.
What this provides is a foundation for simple automation
that, over time, allows organizations to migrate more cost-effectively to other intelligent systems and IIo T solutions.
The IIo T will allow energy solutions tailored to specific needs,
whether that’s simple lighting and [heating, ventilating and
air conditioning] control in your local supermarket or miles
of connected city streetlights.”
Lighting as IIo T infrastructure
While such a system can produce beneficial energy savings, it may not be realizing its full potential if it operates
Intelligent lighting controls are going to play a major role in
the IIo T, but another potential major player is the simple but
ubiquitous luminaire itself. Specifically, LED luminaires.
“Lighting control systems can integrate with building man-
agement systems via BACnet and other integration protocols,”
The U.S. Department of Energy (DOE) estimated total
LED installations at about 215 million units, or 3 percent of the
