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.

Flip Chip Opto Debuts High Power 3-Pad LED Flip Chips
LIGHTimes News Staff
January 20, 2015...Flip Chip Opto launched its new P Series of LED Flip Chip Chip-on-Board
(COB) products. The lighting modules employ the company's patented 45x45 mils
3-Pad LED flip chips with a Pillar Metal Core Printed Circuit Board (P-MCPCB)
to significantly reduce light emitting surface area, junction temperatures, and
thermal decay. The company claims that its technology drives the modules at
higher currents, reduces heat sinks, and reduces chip counts and optics for
improved “Lumen-per-Dollar” performance.
The P-Series COBs reportedly offer high flux density in small LES ranging
9~30mm. They support 24 to 244 watt input power and can come with customized
CCT/CRI. The high "lumen-per-dollar" and low thermal resistance (0.02°C/W to
0.11°C/W) make them perfect for spotlights, high bay lights, down lights,
automotive lighting, and street lights. The P-Series fit the mechanical
holders, optics, drivers and thermal components of existing packages.

pureLiFi Raises £1.5 million in Latest Funding Round
LIGHTimes News Staff
January 20, 2015...pureLiFi of Edinburg, UK, has raised £1.5 million in its latest round of
investment. The 2012 University of Edinburgh spin-out is currently valued at
over £14 million. The company says that a VC funding round is on-going, and
additional funding announcements are expected during the second half of
The funding news comes as pureLiFi ships its first full wireless Li-Fi
networking system. Li-Fi – a term created by the company's chief science
officer (CSO), Professor Haas, refers to a visible light communication
technology that provides full networking capabilities similar to Wi-Fi, but can
have significantly greater spatial reuse of bandwidth.
London & Scottish Investment Partners (LSIP), a Scottish-based angel
group led the latest funding round. Corporate finance firm, Quest Corporate
managed the additional funding, which came from the Scottish Investment Bank
(SIB) and Old College Capital. pureLifi plans to use the investment to support
the development and roll-out of the product roadmap in addition to its
marketing and sales.
In Q4 of 2014, the pureLiFi team launched and shipped the Li-Flame, the
first Li-Fi network product, to customers globally. The system enables
off-the-shelf light fixtures to become Li-Fi access points, which can
simultaneously bi-directionally communicate to numerous users. Li-Flame also
consists of the first battery-powered Li-Fi mobile unit. The unit attaches to a
laptop screen for user roaming within a room or an entire building.
Professor Russel Griggs, pureLiFi’s Chairman, said, “I am
very pleased that the necessary funding is now in place to allow Harald and his
team to push ahead with the product roadmap, positioning pureLiFi for its next
phase of growth.”
Harald Haas, CSO and co-founder of pureLiFi, said, “Li-Fi
is increasingly viewed as a transformative technology that can change the way
we use the mobile internet as part of future 5G cellular networks and at the
same time be an enabler of the emerging Internet of Things.”

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.
