The Convergence of LED Lighting and Wireless Control
will Help Deliver a Building Internet of Things (BIoT)
A report by Memoori
Research to be published later this month will
examine how LEDs and Wireless technology can converge to create
enormous opportunities in smart lighting controls over the next 15
years - http://www.memoori.com/
LED Lighting in both the new construction and retrofit market initiates the demand to replace incandescent lighting and reduce CO2 emissions. However the latent demand in the retrofit market will only be satisfied when wireless control is installed; because only it can meet the ROI requirements of the building owners.
A 3rd driver which is about to kick in is that
wireless smart lighting
control lays the foundation platform to interface with energy
management, life safety, security and a host of other technical
services to ensure that buildings are operated efficiently and cost
The combination of these factors will result in a
transformation of the
wireless lighting business from a bit player to a leading role, at a
time when the lighting industry is in a period of evolution not seen
since the early twentieth century.
It is the impact of LED technology -
that is providing vast opportunities to improve lighting products and
their efficiency, which has coincided with the mandated demand to
reduce CO2 emissions in buildings. But this will come at the cost of
destabilizing this long time established industry.
As our report shows this new importance will also
opportunities to extend its domain into providing control for other
building technical services such as the environment, demand response,
emergency lighting, parking management, evacuation and more. Wired
smart bus based lighting controls have been installed in new
construction prestige buildings for around 20 years and they have
already encroached on these energy related services.
However if the
lighting controls market is to maximize the massive
latent growth opportunity, the only way to do this is through wireless
technology. For whilst the case for retrofitting buildings with LED
lighting has become very compelling it needs wireless technology in
order to bring down the installation cost and improve the return on
investment in this sector.
In addition this will result in LED lighting
controls being installed
in many more buildings that don’t have building energy management
systems and as our report shows -
- bus-based lighting controls have taken on the responsibility for
controlling HVAC services particularly in the relatively small to
medium sized projects where heating and cooling has been achieved
through a combination of chilled beams and natural ventilation. This
has required blinds to control solar gain; which falls into the low
voltage category and has been engineered and designed through the
electrical contract and not the mechanical, as is the case with BEMS.
Whilst the distribution and installation network
to deliver wireless
lighting controls is pretty much in place, wireless technology as
applied to lighting is for the most part being developed outside the
industry. However within the last 10 years new specialist wireless
lighting companies have entered the business and this focus has brought
about many improvements in the reliability and security of wireless
control for lighting and energy harvesting, to reduce the dependence on
Open standards through ZigBee and Enocean have
brought down prices and
enabled plug and play functionality. Players such as Daintree, Dust
Networks, Distech, Harvard, Enlighted, Lutron, Redwood and Wireless
Glue Networks have made headway in wireless lighting control. The
traditional lighting companies such as Acuity Brands, Osram, Philips,
Lutron and Zumtobel have renewed their interest in both wired and wired
controls as they push towards total lighting solutions.
The major factor
that will determine growth of lighting controls over
the next 10 years will depend upon the level of penetration achieved in
opening up the retrofit market, which has seen little growth over the
last 15 years and still only accounts for 10% of the total lighting
This is despite the fact that the latent demand
for lighting controls
in the existing building stock is not far off two orders of magnitude
larger than for the new construct sector. Wireless technology is the
only means of opening up this market by bringing down the installation
cost and significantly improving the ROI.
The market is already driving forward and showing
its potential to
provide a platform for IoT encompassing energy in buildings; which will
determine how buildings will be designed and operated in the future.
