LG Innotek Launches AC Direct LED Lighting Modules and Packages
SSL Design News Staff
September 11, 2014...LG Innotek of Seoul, Korea, announced that the company is beginning to
produce Alternating Current (AC) direct LED lighting packages and modules. On
the surface, these appear to be similar at least in function to the Acrich
modules from another Seoul-based company, Seoul Semiconductor.
The company points out that AC direct LEDs rely on alternating current, the
standard power format for lighting in homes, offices, hospitality, and retail.
Conventional LED lighting uses Direct Current (DC) with Switched Mode Power
Supply (SMPS) units. SMPS units reportedly add cost and complexity to the
The AC direct LED from LG Innotek embeds a micro-drive integrated chip in
the LED that controls the current. The company notes that this allows the LED
solution to occupy a smaller space than conventional LED solutions that require
SMPS units. LG Innotek contends that it can reduce costs by up to 30 percent
compared to conventional DC LED solutions.
LG Innotek is debuting a range of eight products. These products include
five types of AC direct LED packages and three types of lighting modules (a
packaged LED with an integrated circuit board). The company plans to market
three more AC LED modules and two more AC LED packages this year.
AC direct LED packages include the 5250HV(High Voltage), 3030HV and the 5630
HV. The 5630HV operates at about 136lm/W. The company claims that it achieves
the world’s highest efficacy for an AC LED. The company optimized the
3030 HV package for micro bulbs like G9 and G4. The 5630 HV and 5250 HV type
packages have received LM80 certification, the U.S. reliability test standard
for LED lighting.
The AC direct modules are ideal for down lighting. The company's AC direct
LED modules provide light efficiency of 125lm/W, which the company claims is
the best performance in 23W category. The AC direct modules have a CRI above 80
with an optimized light pattern design for excellent light uniformity. AC
direct modules for down lighting avoid dark spots with a uniform light
distribution from a light source placed in the center. The modules also have
built-in connectors to the power source.
A surge protection circuit is embedded in the AC direct modules for bulbs.
The AC module for bulbs is ideal for lighting applications requiring size
optimization because it does not require auxiliary circuits and has a lower
cost than LED modules that do require one. The company plans to offer a 3030W
HV package optimized for omnidirectional bulbs as well as bulb modules and
surface modules later this year.

SemiLEDs Debuts New Chip Scale ReadyMount™ EC LED Series
LIGHTimes News Staff
August 27, 2014...SemiLEDs Corporation has made available its latest line of white chip scale
packages, the ReadyMount™ Enhanced CSP, or EC series. The EC series
combines the company’s Enhanced Flip chip (EF) approach with its
ReadyWhite™ phosphor technology. SemiLEDs boasts that the EC series
offers unprecedented reliability, manufacturability, and flexibility in a
single 1.4 x 1.4mm low-profile packaged LED chip. The EC LED series, an SMD
component, is rated for input power of up to 3W and is ready for surface
mounting on any board level module or COB application. According to the
company, this flexibility in mounting on board level modules or COB
applications lowers capital costs and enables very high lumen density
Mark Tuttle, general manager for SemiLEDs Optoelectronics Co., Ltd.,
commented, “Our unique Chip Scale Package (CSP) brings all the
benefits of SemiLEDs’ rugged EF Series FlipChip architecture to an
extremely compact emitter, which is simple to integrate using standard tape and
reel surface mount manufacturing. This innovation reduces final component cost
up to 50%, with a packaging cost reduction of up to 80% over conventional
packaging. EC Series products, such as the EC-W1414, enable system-integrators
and luminaire manufacturers a direct path to a highly cost effective solution
on a per-lumen basis now, with additional viewing angles and die sizes under
While useful for compact multi-die white LED packages, SemiLEDs says that
its ReadyMount products are particularly useful for light-engine and luminaire
manufacturers who previously relied exclusively upon packaged die solutions.
The EC Series incorporates the EF FlipChip design in which the electrical
contacts are positioned on the bottom of the chip. The bottom positioning
leaves an emitting surface that is uninterrupted by top-side electrodes or wire
bonds. The compact chip-scale package measures just 0.4mm high. At 1A, it can
produce outputs of up to 300 lumens. The SemiLEDs EC series comes in standard
ReadyWhite™ correlated color temperatures from 2700K to 10,000K with
color rendering indices up to 90 minimum. The elimination of the wire allows
nearly edge-to-edge emitting chip surface. Therefore, die can be mounted very
The company says that the glass top surface is also very mechanically
robust, unlike flip chips or wire-bond with a silicone covering. According to
SemiLeds, the ReadyWhite technology enables the typical 145-degree field of
view to provide good color-over-angle characteristics. The SemiLEDs EC series
is ideal for architectural, indoor, and outdoor lighting, as well as
torches/flashlights. The company notes that the LED series’ rugged
architecture and compact size are also well suited for LCD backlighting and
mobile device flashes. SemiLEDs’ EC series of LED chips is RoHS compliant
with production quantities now available.
DOE Publishes 2014 SSL Manufacturing R&D Roadmap
SSL Design News Staff
August 21, 2014...The U.S. Department of Energy published the 2014 Solid-State Lighting
Manufacturing R&D Roadmap. The updated Roadmap complements the SSL R&D
Multi-Year Program Plan that guides the Product Development and Core Technology
R&D programs. One of the roadmap's goals is to guide the Manufacturing
R&D program and help direct funding solicitations for it. The Roadmap also
offers guidance for material and equipment suppliers, based on industry
consensus about the expected evolution of SSL manufacturing.
Industry feedback for the updated report comes from a series of roundtables
with invited experts and from the attendees of DOE's SSL Manufacturing R&D
Workshop that was held in May in San Diego. The 2014 Roadmap adds the
discussion of the OLED manufacturing cost model. DOE says it will continue to
update the Roadmap annually in collaboration with industry partners, to provide
an outline of research and process development priorities, and new analysis as
the technology and marketplace evolve.
Download the 2014
Navigant Consulting conducted the analysis update. Navigant concluded that
in the U.S. the annual source energy savings from LED lighting in 2013 more
than doubled from the previous year to 188 trillion British thermal units
(BTUs). Navigant points out that this is equivalent to an annual energy cost
savings of about $1.8 billion.
While these current energy savings are significant, market penetration is
still quite modest. Navigant estimates that LED-based A-lamps make up only
about 1 percent of all installed A-lamps. However, the company asserts that
growth is happening rapidly. Navigant also reported that from 2012 to 2013 that
the U.S. installed base of LEDs in general lighting applications had more than
doubled to about 105 million units.
Navigant further concluded this that the 188 trillion BTU savings is a tiny
fraction that of the potential energy savings that complete adoption of SSL
lighting in U.S., 4.1 quadrillion BTU. Navigant says that while widespread
adoption may be several years in the future, the potential reveals the need of
developing a robust, high-capacity manufacturing capability for SSL. Market
adoption is likely to accelerate as prices continue to fall, and unit sales are
expected to increase at a much faster rate than revenues, according to
In response to this energy-saving opportunity, the DOE launched the SSL
manufacturing initiative in 2009 to improve SSL product quality and
consistency, establish a strong SSL manufacturing base, and support reductions
in SSL manufacturing cost in the U.S.
Current projects that the DOE Manufacturing Initiative supports include
Philips Lumileds’ development of patterned sapphire substrate technology
for lighting caliber LEDs, Cree’s development of lower cost integrated
LED luminaires, and OLEDWorks’ development of organic light-emitting
diode (OLED) deposition technology for OLED lighting products. DOE-supported
SSL manufacturing R&D projects cover much of the value chain of SSL
production, including designs for lower costs, process improvements,
manufacturing equipment, testing, and materials.
The DOE engaged the LED community through a "Round-Table" meeting of invited
experts to review the state of LED-SSL manufacturing technology and identify
areas for improvement. The DOE followed the meeting with its SSL Manufacturing
R&D workshop and a post-workshop conference call held among
The participants drew several conclusions:
- Achieving the targeted color point adds complexity and cost to the
luminaire manufacturing process especially in applications demanding tight
- Long-term color stability is still poorly understood for LED -based
lighting products and (probably OLED as well). Mitigating color shift over
time adds to the cost of LED lighting products. Furthermore, the
participants report concludes that the ability to understand and predict
color shift over time would simplify the manufacturing process, reduce
manufacturing costs, and increase consumer confidence in LED lighting
- Luminaire manufacturing is now putting less emphasis on the lamp-fixture
paradigm and placing more emphasis on integrated luminaires minimize cost
and maximize efficiency.
- The report concludes that highly flexible luminaire and module
manufacturing will be needed to accommodate the enormous variety of designs
that customers demanded. Production lines will have to be efficient and
cost-effective, even with relatively low numbers for any given product
variant. The required production line improvements may call for innovative
and perhaps more flexible manufacturing methods and equipment.
- The manufacturing of phosphors and down converters and their process of
being applied to LEDs is costly, and innovations in this area could
potentially reduce cost, simplify the manufacturing process, improve color
quality, increase light output, and improve efficacy.
- The domestic OLED community could work together to create a viable OLED
lighting manufacturing infrastructure and promote consumer acceptance of
OLED products. Larger volume production is required to exercise the supply
chain and manufacturing processes in order to identify weaknesses and
- The OLED community is preparing to introduce products for lighting by
examining the barriers in the adoption of LED lighting and understanding
the needs of lighting designers and luminaire makers.
- OLED fabrication methods including vapor deposition approaches and hybrid
approaches are being explored. Efforts are underway to promote a panel
fabrication process solution.
The report concluded that currently, the main challenge for LED lighting is
to continue ramping up production and drive down costs while maintaining
product quality and consistency. The emerging challenge is to demonstrate to
consumers the value that LED technology offers in terms of extended lifetime,
energy consumption and added functionality while avoiding consumer
In the short-term, the expansion of LED lighting manufacturing capacity will
require the refinement of existing manufacturing approaches. Longer-term, it
will require the introduction of innovative approaches to lighting product
design and manufacturing.
The report asserts that the biggest challenge for OLEDs is to develop
acceptable, cost-effective manufacturing processes beyond what is being done
for the manufacturing of OLED displays and build demand by identifying lighting
applications that play to the strengths of OLED technology.
Mid-Power LEDs to Comprise 48 Percent of Packaged LED Revenue in 2014, IHS Predicts
LIGHTimes News Staff
August 19, 2014...The 2014 lighting end market is expected to comprise about 35 percent of all
revenues from packaged LEDs, according to IHS. IHS points at that for the first
time, the end lighting market for packaged LEDs is greater than the market for
packaged LEDs in all backlighting combined. In 2013, backlighting and Lighting
each accounted for 31 percent of market revenue, IHS indicated. IHS forecasts
that Mid-power devices will make up about 48 percent of packaged LED revenue in
lighting applications in 2014 and 81 percent of units sold.
The market has changed drastically in recent years. Back in 2010, high power
LEDs such as 1-watt devices dominated the market, IHS noted. In the west, the
percentage of revenue from mid power LEDs is lower. IHS found that in Asia
however, the percentage is higher. The company points out that numerous Chinese
suppliers that sell LEDs to their large domestic market primarily produce
From 2011 to 2013, the market for mid-power LEDs grew rapidly. IHS says that
this rapid growth was driven by the attractive dollar-per-lumen ratio and the
availability packaged LEDs previously used for backlighting. South Korean
companies such as Seoul Semiconductor and Samsung initially led this trend.
However, mid power LEDs are an essential part of the packaged LED portfolios of
most global companies now. Other suppliers such as Cree, Lumileds, and Nichia
have followed the trend, IHS says.
While Cree is the largest provider of packaged LEDs in lighting
applications. Philips Lumileds is a close second. Despite this, competition
from Asian companies has increased in last few years in lighting
During 2015 and beyond, IHS predicts that the share of mid-power will
continue to increase. Also according to IHS, the proportion of chip-on-board
(COB) LEDs of the packaged LED market is growing and playing an increasingly
important role because companies are designing completed lighting products for
a wider variety of target end markets. IHS says that high-power LEDs are still
popular in areas such as street lighting and should retain a strong presence in
Excluding lighting, the rest of the LED market is almost completely flat
from year–to-year. IHS predicts that the rest of the packaged LED market
will remain flat until 2019. The lighting market, led by mid-power LEDs, will
drive the growth, IHS contends.
SemiLEDs Launches Complete 80mil EV LED Chip Family
LIGHTimes News Staff
August 14, 2014...SemiLEDs of Chunan, Taiwan has begun sampling and made available in high
volume, a complete line of 80x80mil rugged metal LED chips, including blue, UV,
and white varieties. A single member of the EV-80mil family can typically
replace four 40x40mil LED chips and minimize shadow effects and color fringing,
which are common among multi-chip devices. The EV family combines a vertical
LED architecture with rugged copper-alloy substrates. has proven to be
especially. SemiLEDs asserts that the EV family is ideal for handling the
large-chip implementation and their increased thermal and electrical
Mark Tuttle, General Manager for SemiLEDs Optoelectronics Co., Ltd.,
commented, “Applications in commercial and residential lighting,
along with UV industrial applications, share the common challenge of achieving
high output in compact form-factors, in the most cost-effective manner.
SemiLEDs’ unique vertical-metal architectures allow these devices to be
driven hard, without compromising either their stability or reliability,
allowing packagers and integrators to deliver maximum optical power from
extremely small package or chip-on-board footprints.” Mr. Tuttle
continued, “The EV-80mil line is also able to deliver substantial
versatility, including die-level white options that incorporate SemiLEDs’
proprietary ReadyWhite™ phosphor coating technology, which minimizes
blue-leakage and delivers impressive levels of color uniformity with tight
binning options for low-profile and multi-color white packaged
The new EV-80mil ReadyWhite™ chips employ the company's proprietary
phosphor technology. At 3A chips in a typical 5x5mm ceramic package, can
reportedly provide up to 1200 lumens. They chips come in correlated color
temperatures (CCTs) ranging from 2600 to 10,000K, and after packaging, they
have color rendering indices from a minimum 65 to a minimum of 90.
SemiLEDs’ ReadyWhite™ solutions when combined with the company's
vertical LED chip architecture, deliver a package-ready white chip to single-
or multi-die or COB packaging applications. The company claims that its
ReadyWhite phosphor technology eliminates the need for costly phosphor
manufacturing technology. At currents below 1.0A, the 80mil ReadyWhite chips
offer up to 145 cool white lumens per watt in typical package configurations
and are suited for outdoor street or area lighting, or heavy duty
The 80mil blue chips come in standard wavelengths ranging from 445 to 460nm,
with wavelength options up to 470nm available upon request. The chips in
typical ceramic packaging provide up to 4000mW of optical power at 450nm.
SemiLED says that single-chip implementations of the ReadyWhite and blue chips
are ideal for kilolumen applications requiring a narrow beam pattern because of
their simplified optics and compact emitter sizes such as MR/GU/PAR spotlights,
projectors, and automotive front lighting.
“While much of the news in the LED industry is focused on general
lighting, there is an incredible amount of innovation going on in the
industrial and medical arenas,” Mr. Tuttle continued. “The
80mil UV solution from SemiLEDs allows tremendous power per square millimeter
for high output-density industrial requirements. Applications ranging from spot
curing to 3D printing and fiber optic coupled systems, as well as completely
new applications, are all benefitting from the increased optical control that
is enabled by solid state solutions such as SemiLEDs single-die 80mil
series,” he said.
The UV 80mil is available in wavelengths ranging from 360 to 420nm. At 3A in
typical ceramic packages, the UV 80mil has optical outputs up to 4000mW. The UV
LED is for industrial applications, such as spot curing of inks, polymers, and
adhesives, 3D printing, and fiber optic coupled systems. The design of the
80mil enables an 8-10W single chip point source, eliminating the need for
sophisticated optical designs to collimate light and avoiding dark gaps that
are inherent with using multiple smaller chips. The single chip design enables
varying the beam patterns through secondary optics, maximizes delivered UV
optical power across the target areas, and increases UV exposure consistency.
SemiLEDs’ EV-80mil LED chips are RoHS compliant with production
quantities available now.
Osram Continues Restructing with Planned 7,800 Layoffs Due to Traditional Lighting Business Decline
LIGHTimes News Staff
July 31, 2014...Osram's substantial gains with LED-based products in the third quarter of
the fiscal year 2014, nearly offset the considerable shrinkage of its
traditional general illumination business. The company's revenue dropped
somewhat by one percent year-on-year to about €1.2 billion. Osram's
LED-based products business, posted a revenue increase of 21 percent in the
third quarter for 38 percent of consolidated group revenue.
The company announced measures to improve the competitiveness of its
operating units. Osram says it plans on eliminating 7,800 positions globally
over the next three fiscal years. The staff elimination will reportedly include
about 1,700 domestic positions and around 6,100 international positions. As
part of the previously announced second phase of the OSRAM effort, the company
now plans to begin further process improvements and adjust the company business
structure after consulting employee representatives.
Osram began the first stage its restructuring in 2012. The company says that
all measures for the first stage of its restructuring are being implemented or
have been completed. At the end of the third quarter, the cumulated gross
savings from these efforts totaled to aproximately €760 million, including
€118 million from the recent quarter.
During the second stage of the restructuring Osram indicated that it will
greatly reduce the production capacities of traditional lighting products and
will reduce its staff accordingly. In total, the company intends the measures
to lead to a permanent cost reduction of about €260 million until the end
of the fiscal year 2017. Osram expects the gross costs to amount to about
€450 million in the same period.
Osram Opto Semiconductor's, the company's opto semiconductor business
segment posted a 5 percent revenue increase over the same period a year ago.
About €5 million of the improvement comes from the business segment's
recent licensing agreement.
Osram's Automotive Lighting and Display/Optics units, continued to
experience rising demand in the automotive segment to achieve a comparable
revenue increase of ten percent. About 33 percent of total revenue in the
segment came from LEDs. The LED Lamps & Systems (LLS) reporting segment
that covers the business with LED lamps, light engines as well as LED drivers
posted comparable revenue growth of 68 percent in the third quarter due to the
fast-growing LED demand.
The Luminaires & Solutions (LS) reporting segment, which is comprised of
luminaires for professional customers, products for consumers, in addition to
the service and solutions business, recorded a sales decline of 13 percent in
the third quarter because of the reorganization of the service business in
North America. However, strong growth of LED-based luminaires segment the
luminaires business posted a comparable revenue increase.
“While earnings continue to develop nicely, the growing market
acceptance of LED technology is, as already announced, causing a significantly
faster decline of the traditional business,” said Wolfgang Dehen,
CEO of OSRAM Licht AG. “We will successfully complete the first stage
of OSRAM Push shortly. However, we have always stressed that the transformation
of the lighting market will also continue after 2014 and that it will require
additional capacity adjustments. Against the backdrop of the latest
developments, additional measures are now necessary to safeguard our position
as a leading lighting manufacturer in the long term. We need to be even closer
to the customer, further strengthen the entrepreneurship of our segments and at
the same time create cost structures that are appropriate to the size of the
company, but also to that of its individual businesses.”
