LED and OLED Lighting Markets Keep on Rising
2013 LED Professional Symposium attendees value market growth.
ighting and electronic displayindustry professionals continue their
efforts to improve LED and OLED
lighting technologies to create
expanding uses and applications,
but, in truth, the pursuit is a technological and competitive effort to
overtake the marketshare of incumbent lighting products.
LED-based products have enjoyed
healthy, double-digit growth in recent
years, but the organic light-emitting
diode (OLED) market has lagged,
although it's having success in the
smartphone-display field. The two
- LED and OLED - have different,
unique advantages and, of course,
challenges and, therefore, stand
primary in the R&D labs for many
companies and research institutions.
This prevalence was most notable
at this year's annual, LED Professional
Symposium (LpS 2013) and Exhibition
- a leading, international event that
showcases the latest LED lighting
LpS: Europe's leading LED
More than 1,100 attendees from
34 countries enjoyed LpS 2013. The
venue - Festspielhaus Bregenz,
Bregenz, Austria - is popular for
special events, operas and concerts.
Event statistics detailed the attendees'
* Manufacturing companies (60%)
* Distributors (10%)
* Engineering and design services
* Universities (5%)
* Journalists, government officials
and others (17%)
Several points from one keynote
presentation caught my interest:
1. Presently, lighting draws 14% of
Europe's total energy consumption.
2. The projected European lightingmarket growth rate for the next
decade is 7%.
These figures contrast with the U.S.
market where light-energy consumption is roughly 20% of the overall
energy use, and it's expected to
decrease in a few years, due to moreefficient lighting products and the
use of daylight harvesting.
I asked if these aspects (increasing
efficiency and harvesting methods)
were considered in the European
market analysis. And, because the
Samsung's 5.3-in., Super AMOLED Galaxy Note Android v2.3 Phone with 1,280 X
800 resolution. The phone is 9.65 mm thick and weighs 178 grams.

percentage was significantly lower
than the U.S. scenario, I also asked
if this could be due to more efficient
lighting - or if the percentage is
off-balance because of the regions'
high electricity usage in other applications - electric-powered trains
and buses, heating, air conditioning
or other applications, for example.
In both instances, the speaker
said such data was not available.
The European Union's demography is diverse, and the low, 14%
statistic may be affected by inadequate
lighting in many areas - less light,
less power consumption. Further,
the inequality, and accompanying
plan for supplementary light provisioning in many regions, may be
the reason for positive lighting-use
growth projections. Still, a thorough
study would be useful, one that
reveals how daylight harvesting,
energy-efficient lamps and electronic-control systems could affect
the European plan.
LpS 2013 also comprised 46 talks
from presenters who work and
research around the world. The
presentations were divided into
16 sessions: Light Sources I-IV;
LED Future I; LED Systems I-II;
Driver and Controls I-IV; Optics I-II;
Thermal Management I-II; and Applications I. In addition, the symposium
offered workshops on testing and
standardization, 3-D system design
and print technologies, computeraided design of LED and OLED
systems, and LED qualification and
More than 80 international
exhibitors displayed innovations,
products and services across the
sold-out, 2,000-sq.-meter floor
space. Numerous supply-chain
vendors displayed both prototypes
and products that encompassed
materials, optical components, thermal
solutions, drivers, software-design
tools and measurement instruments.
