 GE and Konica Minolta to Show the World’s First General-Lighting
Quality Flexible OLEDs


BUDAPEST — Imagine the impact on the lighting design industry—and life
as a consumer of lighting—if there was a flexible, energy-efficient,
paper-thin light source that could be produced economically.

GE Lighting  (NYSE:GE) will preview potential organic light-emitting
diode (OLED) lighting application ideas during two industry trade
shows this year, Light + Building 2010 in Frankfurt, Germany and
LightFair 2010 in Las Vegas, Nevada, USA. The company will show OLEDs
in a number of configurations at both shows, including fixture
prototypes that help to demonstrate the expected competitive
advantages of GE’s approach to OLEDs: flexibility and an ultra-thin
form factor.

“Lighting is becoming more than just a functional, utilitarian aspect
of an environment,” says Zoltan Vamos, GE Lighting’s Budapest-based
global general manager of lighting technology. “We’re still
experimenting and imagining a future with OLEDs but we think our
approach will allow us to apply light to literally any surface at a
thickness of just a few sheets of paper.”

“OLED technology represents the biggest potential for new product
development and advances in the lit environment,” comments Simon
Fisher, director of product design with LAPD Lighting Consultants,
Lemsford Village, Hertfordshire, UK. “The potential contained within
flexible thin film lighting is enormous and holds the key to changing
the way we design and coordinate lighting into our architecture and
environments.”

According to Sheila Kennedy, AIA, principal of Kennedy & Violich
Architecture, Ltd., “OLED technology presents a new material for
lighting that appeals to our senses, our creativity and our
environment. Imagine an energy efficient, flexible white light that
can be produced with a very low-carbon manufacturing footprint and can
be designed to bend into lightweight, luminous forms or be integrated
into the surfaces of architecture. With flexible OLED materials, GE
has the potential to re-invent the fundamental form and industrial
ecology of the light bulb.”

Researchers and product development teams from GE Lighting in
Cleveland in partnership with Konica Minolta Holdings, Inc., Konica
Minolta Technology Center, Inc. (collectively KM) and GE’s Global
Research Center in Niskayuna, New York, have been working together on
OLED technology since 2007. GE’s technology partnership with KM, a
world leader in imaging products, has enabled GE engineers to tap into
KM’s thin-film technology, which plays an important role in the
development of highly productive OLEDs.

“The time is right for OLEDs to emerge as an option for consumers, as
new energy regulations taking hold around the world are impacting the
design, use and disposal of lighting products,” notes Vamos. “OLEDs
are a gateway to limitless design possibilities that can keep pace
with protocols today and anticipate those yet to come.”

GE has worked with a number of prominent lighting designers,
architects and graphic designers, including Fisher and Kennedy, to
ensure its early OLED solutions can be used in real-world scenarios.
OLED solutions produced as GE and KM envision hold promise for
lowering the costs to produce, use and maintain lighting. GE’s OLED
solutions will be mercury-free, lightweight and dimmable.

What are OLEDs?

OLEDs are thin, organic materials sandwiched between two electrodes,
which illuminate when an electrical charge is applied. In addition to
widespread design capabilities, OLEDs have the potential to deliver
dramatically improved levels of efficiency and environmental
performance, while achieving the high quality of illumination found in
traditional light-emitting diode (LED) systems.

KM was the first company to develop proprietary blue phosphorescent
materials. In 2006, KM combined this material with multi-layer film
design and innovative optical design technologies to successfully
develop white OLEDs. KM’s experience making photosensitive materials
and coatings has enabled the development of a highly productive
roll-to-roll coating process using advanced barrier films that are
considered indispensable for prolonging the life of OLED lighting.
This approach, similar to newspaper printing, is expected to be less
costly than the common evaporation method that forms films one by one
on glass substrate. The few organic electronic products on the market
today are made with more conventional batch processes and are
relatively high in cost.

KM sees OLED lighting as one of its most promising new businesses. It
began the construction of a new pilot line in November 2009 to
establish a mass production capability. The line will be completed in
the autumn of 2010. A roll-to-roll manufacturing infrastructure that
enables high performance and low cost devices will allow a more
widespread adoption of GE’s OLEDs when commercialization of the
product—various sized panels of light (based on 75-mm X 150-mm or
3-inch x 6-inch)—starts in 2011.

GE Fast Forwards to Future of LED Lighting


Unveils unique LED bulb designed to distribute light like an
incandescent bulb, last 17 years

CLEVELAND – The inventor of the first visible light-emitting diode
makes history again this year as it begins to show customers a 40-watt
replacement GE Energy Smart® LED bulb available later this year or
early 2011. GE Lighting's new LED bulb is expected to consume just 9
watts, provide a 77 percent energy savings and produce nearly the same
light output as a 40-watt incandescent bulb, while lasting more than
25 times as long.

The new GE Energy Smart® LED bulb is expected to outperform currently
available products that may be underwhelming consumers right now. GE
scientists and engineers designed the bulb to better direct light
downward on the intended surface and all around, not just out the top
of a lampshade, as most current LED bulbs are prone to do. The new GE
LED bulb offers 450 lumens—the Energy Star® threshold to be considered
a 40-watt incandescent replacement. Currently available LED bulbs
produce 350 lumens or less. GE has filed multiple patent applications
for the bulb and expects it will be an ENERGY STAR®-qualified LED
omnidirectional light bulb.

“This is a bulb that can virtually light your kid's bedroom desk lamp
from birth through high school graduation,” says John Strainic, global
product general manager, GE Lighting. “It's an incredible advancement
that's emblematic of the imagination and innovation that GE's applying
to solve some of the world's biggest challenges.”

GE Energy Smart® LED bulb product snapshot:

    * Expected to consume just 9 watts—compared with 40-watt
incandescent/halogen or 10-watt CFL, while delivering nearly the same
light output;
    * Expected 25,000-hour rated life—will last 17 years (4 hours per
day), which is 25 times longer than a general service 40-watt
incandescent or halogen bulb and more than 3 times longer than a
standard 8,000-hour rated life CFL;
    * LED technology delivers the instant full brightness of an
incandescent or halogen bulb;
    * Durable solid-state design with no filament to break;
    * Contains no mercury and will be RoHS compliant; and
    * Feels cooler to the touch than CFLs and far cooler than
incandescent bulbs.

The 9-watt GE Energy Smart® LED bulb, a replacement for 40-watt
general service incandescent bulbs, hits store shelves this fall or in
early 2011. Retailers set pricing but it is expected to be $40 to $50.
The new bulb joins GE's growing family of LED bulbs in a broad range
of shapes, wattages and colors, including, spot and flood lights
(PAR20 & PAR30), ceiling fan bulbs (A15), medium globes (G25), small
globes (G16.5), candles (CA10), and night lights (C7). All of GE's
Energy Smart® LED bulbs are rigorously tested to ensure constant
color, long life and verifiable lumen ratings. For more information,
visit www.gelighting.com or www.whatsyourlightingstyle.com. To learn
about GE's dedication to LED quality standards, visit
www.gelighting.com/apples-to-oranges.

GE will put prototypes of the bulb—outfitted with Cree XLamp® XP-G
LEDs—on display at two upcoming trade shows: Light + Building 2010 in
Frankfurt, Germany, and LightFair 2010 in Las Vegas, Nevada, USA. The
high-efficiency, high-lumen-output LEDs used in the GE bulbs are
Cree's smallest and brightest lighting-class LEDs, designed
specifically for general lighting.

“The introduction of high-quality retrofit light bulbs, like the GE
Energy Smart® LED bulb, is a key next step in the LED lighting
revolution,” notes Norbert Hiller, Cree vice president and general
manager, LED Components.

Strainic adds: “Consumers have been reluctant to move away from less
efficient incandescent bulbs because they love the light quality. This
new GE Energy Smart® LED bulb will address that lighting preference
head-on and give consumers yet another option to light their homes and
businesses.”

New Lighting Legislation
Starting in 2012 and continuing through 2014, standard incandescent
light bulbs are going away as a result of U.S. federal lighting
efficiency standards:


    * 100-watt bulbs can no longer be made in January 2012;
    * 75-watt bulbs can no longer be made in January 2013; and
    * 60- and 40-watt bulbs can no longer be made in January 2014.

GE has consumers covered each step of the way with alternatives such
halogen, CFL and LED bulbs that already meet the new efficiency
standards.
