COB LED Market to Nearly Triple from 2014 through 2020, According to Strategies Unlimited
LIGHTimes News Staff
January 27, 2015...Strategies Unlimited latest report about the COB LED market predicts that
the market for COB LEDs will grow from $1.54 billion in 2014 to 4.35 billion in
2020. The research firm also predicts that the COB LED market will grow by 40
percent in 2015 compared to 2014.
The company contends that the long term growth in the COB LED market is
mainly due to the increased penetration of COB luminaires and lamps into some
specific lighting applications, such as spotlights and downlights.
Martin Shih, annalist at Strategies Unlimited noted,"With better light
distribution and design flexibility, we expect a significant growth for COB,
especially in directional lighting applications."
Shih points out that COB LEDs are wide-area emitters, making them perfect
for applications such as high bays, downlights, spotlights, and street
Shih says that in certain applications, heat management and government
regulations are the primary impediments to driving demand. One such initiative
that could slow the penetration rate is the “Dark-Sky Movement,”
which seeks to reduce light pollution.
While LED lighting is known to be the main driver of the COB LED market
growth, the company says that LED packagers must catch the growth of the COB
market by application and by region to explore the market opportunities.
Because the market for COBs is poised to see growth, the company forecasts that
the markets for some specific applications will have 11%~28% CAGRs from 2015 to
2020. According Strategies Unlimited, COBs will eventually dominate the market
in some lighting applications.

SSL Design News Staff
January 27, 2015...Recruiting firm, Green Resources of Raleigh, North Carolina USA, reported
last week to the State Department of Commerce that the company is laying off
319 contract workers who worked for its client Cree Inc. Mikio Anderson, the
company's vice president of human resources indicated in an article
in News Observer that the employee reduction at Cree was due to an a
product that has become obsolete, and the new version of the product will be
produced outside of the United States. The employees who are effected work at
Cree's facility on S. Alston Avenue which makes LED bulb products. Cree stated
that its "contract workforce historically fluted to match our business
needs. Our Cree employee base remains solid and continues to grow."
China LED Chip Production to Soon Exceed Taiwan's for First Time
January 27, 2015...China's production value of LED chips is expected to exceed Taiwan's for the
first time in 2015 or 2016, according to a Digitimes article that cited
Taiwan industry sources. The article noted that while some China-based LED
chipmakers withdrew from the market, larger ones including HC SemiTek, San'an
Optoelectronics, Aucksun, and Suzhou Nanojoin Photonics used government
subsidies to expand production capacities.
The subsidies specifically went into adding MOCVD systems in 2014. About 155
to 170 MOCVD systems were added for additional LED production in China in 2014.
In total China currently has 1172 MOCVD systems. More than 250 MOCVD systems
are expected to be added for LED production in 2015. Most will go into
producing 4-inch LED epitaxial wafers.
With the addition of 155-170 MOCVD sets in 2014, there are 1,172 sets in
total in China currently, according to the article. In 2015, more than 250
MOCVD sets, mostly for making 4-inch LED epitaxial wafers, are expected to be
added, the industry sources noted.
China-based LED chip makers including subsidiaries established by
Taiwan-based LED chip producers reportedly boosted LED chip production by about
40% in 2014 to about US$1.95-2.24 billion. The total production value of LED
chips from china is expected to grow by 35% in 2015.
Hubbell Lighting Introduces LED Fixtures for Horticulture
LIGHTimes News Staff
January 27, 2015...Hubbell Lighting of Greenville, South Carolina, launched an LED fixture
specifically designed to deliver nearly 100% usable light for plant growth with
virtually no wasted energy. The product from the company's Industrial Lighting
division is called NutriLED. The company says that NutriLED provides spectrally
tuned light to optimize growth and germination for virtually any indoor
Hubbell points to recent studies showing increased growth rates and yields
from growers utilizing LED lighting. According to Hubbell, plants only absorb
the blue wavelength and red wavelength portions of light, not utilizing any of
the other wavelengths. NutriLED reportedly creates an ideal blend of red and
blue wavelengths and light intensities for chlorophyll absorption. Hubbell says
that this ideal light combination means virtually no wasted goes into producing
spectrums of light that don't benefit plant growth. According to the company,
NutriLED provides up to 88% energy savings compared to non-LED grow lights and
delivers enormous maintenance savings and greatly minimizes waste.
An additional benefit of the NutriLED lighting is the tremendous reduction
in radiant heat from conventional lighting, which can lead to a 50% reduction
in water usage and can also lead to a complete elimination of supplemental HVAC
cooling loads for some applications.
The NutriLED allows for multiple mounting configurations running linearly or
parallel and to light plants from virtually any angle. Additionally, the
NutriLED’s unique optical design offers controlled, uniform illumination
with a 60-degree beam spread that yields a 1:1 spacing ratio.
Cree Debuts XLamp MH Family of Ceramic COB LEDs
LIGHTimes News Staff
January 22, 2015...Cree has introduced the new XLamp mid-power high lumen density (MH) family
of chip-on-board (COB) LEDs. The Durham, North Carolina company announced the
first members of the family, the MHD-E and MHD-G. Both offer high lumen density
and the reliability of a ceramic chip-on-board LED and a surface-mount package.
The LEDs employ elements of the Cree SC5 Technology™ Platform. Cree says
that the MH family enables superior performance with new designs and
significantly lower system costs.
“The high lumen output and high reliability of Cree’s new MHD-G
LED allows us to develop a new downlight that outperforms other downlights in
the market,” said Baly Luo, general manager, Aeon Lighting Technology.
“ALT’s compact-size, 4-inch downlight that is built with the
MHD-G LED generates over 1,800 lumens at 3000 K while other downlights can only
produce 800 to 1000 lumens.”
The LEDs offer the Cree EasyWhite® technology in a 7-mm x 7-mm package,
XLamp MH LEDs allow a smaller board size, tighter beam angle and a more
traditional appearance than conventional mid-power LEDs. Delivering more than
1800 lumens at 14 W and 2500 lumens at 19 W respectively, the XLamp MHD-E and
MHD-G LEDs are perfect for high-lumen, semi-directional applications such as
high-bays, downlights, and outdoor area applications.
“At Cree, we continue to deliver innovative products that give our
customers a competitive edge in the marketplace,” said Paul Thieken,
Cree director of marketing, LED Components. “With the MHD LEDs,
we’re offering chip-on-board performance to lighting manufacturers that
prefer surface-mount technology, making it easier for them to achieve lower
system cost than with the same commoditized mid-power LEDs that everyone is
Cree XLamp MHD-E and MHD-G LEDs come in 2700 K – 6500 K correlated
color temperatures with high-CRI and multiple voltage options. Samples are
available, and production quantities are available with standard lead times.
Nichia and Mitsubishi Chemical Reach Patent Cross-Licensing Agreement Related to Red Phosphor for White LEDs
LIGHTimes News Staff
January 22, 2015...Nichia Corporation, Citizen Electronics Co., Ltd., Mitsubishi Chemical
Corporation, and National Institute for Materials Science, reported that Nichia
and MCC have concluded a cross-licensing agreement for patents related to
nitride-type red phosphor, which is frequently used in white LEDs.
The conventional white LED using a yellow phosphor has been available for
many years, but Nichia points out that its white light had less of a reddish
component than natural light. The nitride-type red phosphor, called CASN or
SCASN phosphor (or 1113 phosphor) can add this reddish component to white LEDs
for a white light that is closer to natural light. The white LEDs containing
this red phosphor are also used in a variety of lighting applications and in
backlighting for LCD panels.
The new agreement finalizes the basic cross-licensing agreement that Nichia
and MCC reached pertaining to each company’s red phosphor patents in
2010. The cross-licensing agreement targets Nichia’s patents and MCC and
NIMS’s patents. In addition, the companies also reported that Nichia,
MCC, Citizen, and NIMS have agreed to share the U.S. patent (No. 8409470),
which is one of the basic patents that MCC and NIMS currently co-own.
The companies expect the completion of the cross-licensing agreement and
shared U.S. patent to further stabilize their patent rights related to the red
phosphor, and enhance the business base of Nichia and MCC. Nichia, MCC,
Citizen, and NIMS reportedly plan to continue their initiatives to expand the
white LED market using the red phosphor.

Commentary & Perspective...
The Significance of the LED Lighting Industry
SSLDesign/LIGHTimes Editorial Team
January 4, 2015...A big motivation (or frustration)
factor in most people's lives is significance. When we feel we we're making an
impact, not only do we feel better about ourselves, we feel better about pretty
much everyone. We we don't think we're making a difference, things will typically
start to fall off the rails. Apathy being the mild symptom, and tragedy being
the extreme. As we kick of 2015, we'd like to stake out our position concerning
LED technology and LED lighting: The industry has huge significance, and anyone
supplying, applying or producing should be proud of their contribution.
can't say that the rest of the world will point at folks in the industry as rock
stars any time soon. While not as behind the scenes as the folks that really pioneered
the Internet, for instance, we also won't be seen in the same light as the gang
that launched the first astronauts or crossed the ocean nonstop. What people will
recognize, in the not too distant future, is that LED lighting has made their
world better. Better light, better health, better efficiency, and probably most
recognizably, enabling us to better connect with the spaces we occupy.
this is coming as a parallel of two elements: 1) The capabilities of LEDs to allow
us to unlock the "secrets" of light; and 2) The coming real smart
The secrets of light... Light is one of those
elemental things, and we could easily lump it together with food and water as
simply something we need. But saying that would be pretty much the same as saying
all food is the same, and has the same effect on us. We know that's not true,
although arguably, if we compare the total food to the nutritious food consumed
by a teenage boy, we might have one datapoint to the contrary. For the rest of
us humans though, junk food begets junk health. Guess what...? We're figuring
out as well that junk light begets junk health as well. Whether we end up messing
up our melatonin/melanopsin cycle by soaking in too much computer, TV or iWhatever
time at bed time, or simply working night shifts because light allows us too,
we're figuring out that there is an effect. Philips is investing a lot in doing
studies in hospitals that combine natural lighting with providing a more desirable
collection of visual elements in the patient's view, and correlating that to healing
time. Children's wards are being equipped with more controllable lighting to allow
kids to "paint" their spaces (hopefully too much cold-bluish isn't on
the palette for bedtime...). The Lighting Research Center (LRC) at RPI has been
turning out great information for a number of years, and the output is accelerating
as their tools continue to grow. A visit to their research program overviews (here)
as well as the list of publications (here)
can provide a good sense of the scope of what we're starting to learn.
is being done by a number of researchers to help us better understand what and
how both our visual and non-visual photoreceptors really work, and what other
effects they may have on our biological systems. Horticulture and such things
as poultry farms are giving us some pretty good hints at what is to come as we
experiment, both rigorously and "on the job", and see real results from
changes in our approach to lighting. (A good browse can be found at Once Innovations
Agricultural Lighting site (the Science
section), which has a good mix of data and studies that can set thought processes
in motion). Who needs genetically modified crops when we can simply deliver light
that gives the plants what they want, and maybe even curtails the pests, all in
The real smart lighting revolution... We have smart TVs
that are smart because they connect to the Internet. We have smart phones because
the connect, and have apps. We have smart snacks because they don't have "unnatural"
ingredients. (High fructose corn syrup and natural flavors are natural too...
maybe not the best criteria). Take a light, add a microprocessor so do something,
and you can call it "smart", but like that snack food, that's just marketing.
Real smart lighting will be connective, adaptive and aware. We've mentioned before
that integrated controls are going to be as basic a requirement for lighting as
a touch screen is to a smartphone. What's going to distinguish real smart lighting
is that it's going to not only include connected controls and sensors, but it's
going to know what to do with that data. That includes the local decision making
directly related to the amount and type of lighting from any given luminaire,
as well as knowing what to aggregate and pass along to the higher level systems
as part of it's membership in the Internet of Things. If the temperature in the
room is supposed to be between 72 and 74 F, does the building management system
need to know it's still 73 now? And now? And still now? Or does it simply need
to know when the temp strays below 72 or above 74. "All is well" gets
a bit cumbersome every few seconds, especially if you're involved with anything
that uses batteries or other energy harvesting. Save your breath, remote device...
And that brings us to the result of this real smart lighting. Yes, there
will be better, more granular, information about the space below the light (Check
into some of what's up, especially with sensors, at the Smart
Lighting Engineering Research Center (ERC) for what's going on beyond just
how much light, and what's the temp. Cool stuff includes time of flight info that
can use light travel times to tell you how many people are in a room, where they
are moving, and whether they are sitting or standing). And yes, there will be
better control of the light. Pick your color, pick your style, pick your cycle.
But what's really most impactful is that the light will know your color, your
style and your cycle. The light won't just be connected to the IoT, it will be
connected to you. Which means connecting the person and the space. In it's own
significant way, the light will acknowledge your significance. Your cause and
effect relationship with the space, and by implication, the bigger world.
us, the fruit of our collective efforts, for health, well being and the higher
level of "connectedness" that lighting will impart, will be become obvious
to all, very soon.
