Rayben MHE®301 Behaves Excellent Performance In High Power Application
Top
With twenty years of PCB design
know how and manufacturing
experience, Rayben have
developed a very successful
thermal conduction PCB
technology for high power LED
application called Micro Heat
Exchanger.
MHE301 has already UL
approved and in mass
production for 2 years. It does
provide both copper
(390W/m°C) and aluminum
alloy (230W/m°C) as base
material.
This technology stems from the
concept of direct thermal contact
between thermal pad of LED
components and the base material
of MCPCB, with the opening of
dielectric layer.
Such structural changes basically
remove the thermal resistance
created by the di-electric layer
which has typical thermal
conductivity value of 2 to
4W/m°C. Essentially, the
temperature difference in PCB
layer is theoretically eliminated by
the effective metal conduction
capability (Copper: 390W/m°C).
With such temperature difference
saving, it would either allow (1)
pump in 35% more power to LED
so as to gain high lumen at same
cost or (2) reduce the heat sink
size by 30% so as to maintain
same lumen and operation LED
junction temperature.

Philips Lumileds Announces Board-Level Modular LED Light Engines
Philips Lumileds has announced
the Matrix Platform including the
Luxeon XR and XF family of
modular LED light engines that
consist of LEDs mounted on rigid
or flexible printed circuit boards
(PCBs) as a building-block
product for solid-state lighting
(SSL) developers. Lumileds, and
others in the SSL industry, refer
to such PCB-based products as
Level 2 products differentiating
the customer engagement from
Level 1 products or individual
packaged LEDs. The initial
Luxeon Matrix products target
troffers and other linear
applications.
Packaged LEDs are increasingly
difficult for some lighting
manufacturers to work with at
the component level. Both midpower LEDs and high-power
devices in flip-chip or chip-scale
packages (CSPs) require
automated assembly on highend surface-mount device
(SMD) production lines. Indeed,
when Lumileds first pioneered
the CSP LED last year, the
company said many customers
would buy products that use the
LED in a Level 2 engagement with
the LEDs already mounted on a
PCB, thereby simplifying both the
product development and
manufacturing processes.
The Matrix Platform is meant to
offer the aforementioned benefits
in form factors that are optimized
for specific applications. "More
than ever, luminaire manufacturers
need robust solutions that meet
their specific design requirements.
That need, together with today’s
time-to-market pressures, inspired
our Matrix Platform," said Viral
Hazari, product line director for
the Matrix Platform at Lumileds.
"Based on customer requirements,
Philips Lumileds can provide
Luxeon XR and Luxeon XF
solutions designed with any
Luxeon LEDs. Additionally, there
are both off-the-shelf and built-tospec options."
The initial Matrix press release
covered specifically the off-theshelf XR and XF families that use
Lumileds mid-power Luxeon 3535
LEDs. The Luxeon XF-3535L
product family features a single
row of LED components mounted
on a flexible PCB in strip fashion
for applications ranging from cove
lighting to T8 LED tubes. The
Luxeon XR-3535L products feature
rigid PCBs with a by-3
arrangement of LEDs with two
series of components mounted
parallel to one another. The XR

products target applications
ranging from ceiling troffers to
outdoor area lights.
Developers will get an initial
choice of 3000K, 3500K, or
4000K CCTs in the XR family
with all of the products
specified at a CRI of 80. The
PCB measures 280×55 mm
about (11×2.2 inches). Typical
lumen output ranges from
1320–1419 lm with efficacy in
the 142–152-lm/W range. The
form factor is also compliant
with some Zhaga Consortium
books.
The XF series comes in far more
configurations for now with
CCT ranging from 2200K to
5700K and module lengths of
300, 525, 600, or 1150 mm. At
2700K flux output varies from
1080–3240 lm across 300–600mm versions of the product.
Efficacy varies broadly with
CCT from 112–157 lm/W.
Still, long term it may be
flexibility in configurations of
the modules that will be most
valuable to developers.
Lumileds emphasized that it
will offer custom options in
terms of LED types and form
factor.

Philips Lighting Adds Flexibility In The Fortimo LED Downlight Module Family
Philips Lighting has released a
new version of its Fortimo DLM
LED downlight module that offers
developers more flexibility in
product development. Indeed, the
DLM Flex can be ordered as a bare
printed circuit board (PCB) light
engine, in a new low-profile
packaged module, or in the legacy
Fortimo DLM form factor.
Moreover, Philips has gone away
from the remote-phosphor design
that it previously used in the DLM
family, moving to phosphorconverted LEDs as the nearby
photo illustrates.
Remote phosphor implementations
have in the past offered higher
efficacy and more uniform color
performance over time than do
phosphor-converted packaged
LEDs. The color advantage comes
courtesy of the distance between
the blue-pump LEDs and the
phosphor in a remote design. The
phosphor isn’t impacted by the heat
radiated from the LED junctions
and therefore the phosphor doesn’t
degrade as rapidly over time.
Philips has used remote-phosphor
technology in the Fortimo DLM
family up through the Gen 5 family
announced one year back. Likewise,
the company used remote-phosphor
technology in many retrofit lamps
only to move toward phosphorconverted LEDs in late 2012.
In the case of retrofit lamps, the
move away from remote phosphor
was presumably due to consumer
preference for a white lamp in the
off state as opposed to the yellow or
orange remote-phosphor lamps. The
off-state appearance was likely less
of a factor in the move to the DLM
Flex. In the DLM, remote-phosphor
implementations require a mixing
chamber that impacts the size of
the module. Philips would not
have been able to deliver the
new low-profile or PCB options
with remote-phosphor
technology.
Philips said the new design
delivers 15% better energy
efficiency that the prior Gen 5
LED module. The company
offers the modules over the
range of 1100–5814 lm. The new
low-profile model is only 22 mm
high, thereby enabling less
bulky downlights. Meanwhile,
lighting makers that have used
the prior DLM modules can
drop the larger module into
existing designs. And the PCB
offers maximum flexibility in
mechanical designs.

Yole Predicts: In The LED Packaging World, Flip Chip Technology Is Rising
In the LED packaging world, a
wind of change is blowing. A LED
TV crisis, and new Chinese players
have totally modified the LED
industry and its supply chain.
Under this context, with a high
competitive environment, new
challenges have been identified by
Yole Développement (Yole)
analysts: efficacy improvement, cost
decrease … To answer to the LED
market needs, companies have
today to innovate their technologies
and implement new solutions like
Flip Chip for LED packaging.
“In 2013, LED based on Flip Chip
technology represented 11% (in
volume) of the overall high power
LED market; such market share
should reach 24% (in volume as
well) by 2020”, explains Pars
Mukish, Senior Market and
Technology Analyst, LED, OLED &
Compound Semiconductors, at Yole
(Source: LED Packaging 2014 report,
to be released end of
September 2014).
Predictions of the volume percentages for different LED types show the
expected growth of the Flip Chip technology from 2013 to 2019
Nanotechnology May Lead To Better, Cheaper LEDs
Princeton University researchers
have developed a new method to
increase the brightness, efficiency
and clarity of LEDs, which are
widely used on smartphones and
Top
portable electronics as well as
becoming increasingly common in
lighting. Using a new nanoscale
structure, the researchers, led by
electrical engineering professor
Top
Stephen Chou, increased the
brightness and efficiency of LEDs
made of organic materials (flexible
carbon-based sheets) by 57
percent. The researchers also
report their method should yield
similar improvements in LEDs
made in inorganic (silicon-based)
materials used most commonly
today.

LED's structure traps most of the
light generated inside the device;
the new system, called PlaCSH,
guides the light out of the LED.

from center to center. An image of
the experimental LED is shown at

The method also improves the
picture clarity of LED displays by
400 percent, compared with
conventional approaches. In an
article published online August 19
in the journal Advanced Functional
Materials, the researchers describe
how they accomplished this by
inventing a technique that
manipulates light on a scale smaller
than a single wavelength.
Blue LED creators receive Nobel Prize in Physics for 2014
The Royal Swedish Academy of
Sciences has awarded the 2014
Nobel Prize for Physics to the team
of researchers that created the first
blue LEDs in the early 1990s and
ultimately enabled functional white
light output from LED sources.
Isamu Akasaki (Meijo University,
Nagoya, Japan and Nagoya
University, Japan), Hiroshi
Amano (Nagoya University,
Japan), and Shuji Nakamura
(University of California, Santa
Barbara, CA) have been honored

Princeton has filed patent
applications for both organic
and inorganic LEDs using
PlaCSH. Chou and his team are
now conducting experiments to
demonstrate PlaCSH in red and
blue organic LEDs, in addition
to the green LEDs used in the
current experiments. They also
are demonstrating the system in
inorganic LEDs.

"for the invention of efficient blue
light-emitting diodes which has
enabled bright and energy-saving
white light sources."
The trio of scientists will formally
receive their Nobel awards in
December at a ceremony in
Stockholm. The three will also
share a monetary prize of SEK 8
million ($1.1 million). The
Academy noted that the blue LED
was crucial in creating white light
by combining with existing red
and green LEDs. More recently,
the white light is most often
generated by a blue LED along
with a mix of yellow, red, and/or
green phosphors in a phosphorconverted white LED.
The Academy released the
infographic depicted nearby that
Rayben Group
Issue 4, 15 October 2014
demonstrates the impact that LED
sources can have on energy
consumption. Indeed, LED sources
have reached 300 lm/W in efficacy
in the lab. At the system level,
shipping solid-state lighting (SSL)
products regularly achieve efficacy
in the 150 lm/W level.
"With 20% of the world’s electricity
used for lighting, it’s been
calculated that optimal use of LED
lighting could reduce this to 4%,"
said Frances Saunders, president of
the Institute of Physics, in response
to the Nobel announcement.
"Akasaki, Amano, and
Nakamura’s research has made
this possible and this prize
recognizes this contribution."
