July 1, 2009...The US Department of Energy recently finalized the ongoing energy efficient lighting programs and mandates that have been in the works since 2007. Under Energy Secretary Stephen Chu, the DOE has also added some $50 million in new funding from the Recovery Act to the existing DOE programs.
Contrary to what several news sources and press releases seem to imply, while some additional monies have been added under the Recovery Act, the Obama administration has specified the use of $346 million appropriated by congress for energy efficiency programs that actually date back to the 2007 Energy Independence and Security Act, which amended for the second time the 1975 Energy Policy Conservation Act. That act established a national energy conservation program for household appliances. This program was first amended in 1992 and then again in 2007 with the 2007 Energy Indepedence and Security Act (EISA).
(Ref: Statutory Authority of Appliance and Commercial Equipment Standards).
Among the many provisions, the EISA legislates a phase out of incandescent bulbs in the United States. The EISA 2007 also requires that the Secretary of Energy to develop a unit sales forecast for 2010-2025 for five lamp types exempt from the general service incandescent lamp standards.
Stephen Chu made this sales forecast available.
Of the $50 million appropriated for solid state lighting research and development, $8 million is for Round IV of the Solid State Lighting Core Technologies program; Another $11.5 million is for Round VI of the Solid State Lighting Product Development program, and some $22 million of it is for Round I of Manufacturing for US.

DOE Revises L-Prize Competition to Allow Broader LED Sourcing Options SSLDesign News Staff
June 30, 2009...The U.S. Department of Energy has revised the requirements for the L-Prize, a government sponsored competition to accelerate the development of efficient solid state lighting products to replace standard A-19 and PAR-38 light bulbs. The new rules have made it possible for non-USA based LED suppliers' products to be eligible as components in the winning LED light bulbs. The previous rules required that the LED die or chip must be made in the United States, essentially limiting the competition to U.S. companies using LED die from one or possibly two U.S.-based companies.
The revised rule now states, "A majority (≥75% by count) of the LED die or chip... must be manufactured in the United States. Or, the LED must be packaged in the United States. Packaged LED (also known as an LED device) refers to an assembly of one or more LED dies possibly including the mounting substrate, encapsulant, phosphor if applicable, electrical connections, and optical components along with thermal and mechanical interfaces. "
A third "or" condition in the rule revision effectively opens the door to non-US die and components by stating, "... Or, a majority (≥75% by subsystem and assembly cost) of the final product assembly/integration must be carried out within the United States. This includes all of the applicable: final assembly of the LED die or chip, packaged LED, optics, heat sink or cooling components, and driver and electronics." Eligibility is still restricted to US-based businesses, stating, and In the case of a private entity, the entity shall be incorporated in and maintain a primary place of business in the United States; and in the case of an individual, (whether participating as a single individual or in a group)."
The rule leaves open the possibility of a U.S. based company purchasing die, packaged chips, or components from a company outside the U.S. and then either packaging 75 percent or more of the die or assembling 75 percent or more of the final lamp product (by cost) in the United States. With the revised rules, many more companies will likely enter their LED-based bulbs for the opportunity of a share in the $10 million prize that the US Congress has required the DOE to put on the table. The revisions also include new requirements in which the correlated color temperature specification is now accompanied by specifications for chromaticity, as well as refinements to the required center beam candle power (CBCP) with regard to PAR-38 entrants.

ON Semiconductor Introduces 10 A Supercapacitor-Based LED Flash Driver LIGHTimes News Staff
June 30, 2009...On Semiconductor of Phoenix, Arizona USA, has introduced the NCP5680, a 10 A supercapacitor-based LED flash driver for ultra-slim cameras.
It is reportedly an integrated LED flash and power management solution with a 0.55 mm low-profile package. On Semiconductor contends that the new flash driver extends battery life and significantly improves digital photo quality
The driver is for photo flash and video light in ultra-slim camera phones and compact digital cameras.
The company notes that the NCP5680 can be combined with the latest thin, prismatic supercapacitors - such as those offered by CAP-XX and licensed by Murata Manufacturing Co. Ltd., Japan with a capacitance of up to 0.9F at 5.5 V. The company says that these components can also be integrated with the high-power LED OSLUX from Osram, an LED specifically designed for camera flashes.
The company points out that cameras of 5 megapixels or more require a high-intensity flash and white LEDs can provide such a flash, but they require up to four times the power that a camera battery can support. On Semiconductor says the integrated driver can also power other high-peak-current circuits in portable systems, such as audio amplifiers.
“The NCP5680, combined with an ultra-thin prismatic supercapacitor, delivers an ideal LED flash and power management solution for slim camera phones and digital cameras,” said Marie-Therese Capron, ON Semiconductor director of low voltage power management products. “This total LED flash solution supplies comparable light energy to xenon flash, but with only half of the comparable solution height, and no need for an extra LED for video capture. Because the NCP5680 enables the Lithium-ion battery to support more power-hungry functions for a longer time, this new supercapacitor-based power management solution enables smart phones to offer ever richer functionality.” Company News Release
LED Revenues from Notebooks to Reach Over $800 Million in 2010, Electronics.ca Says LIGHTimes News Staff
June 25, 2009...Electronics.ca, a market research and knowledge firm, predicts that LED revenues from notebooks will more than quadruple from $200 million in 2008 to more than an estimated $800 million in 2010. The forecast comes from the company's new research report according to a new research report that is available at Electronics.ca, entitled "World Market for Optoelectronic Components".
Jamie Fox, a market analyst for the company, says that LED backlit notebooks made up about 10 percent of all notebook sales in 2008. He predicts that in 2010 LED-backlit notebooks will make up 50 percent of all notebooks sold worldwide.
The company points out that although LED solutions are more expensive than cold cathode fluorescent lamp backlighting, they have better power efficiency, offer better color saturation, are thinner, and do not use mercury.
The company indicated that notebook and desktop computer producer Dell, has already publicly committed to using LEDs in all their notebooks by 2010, and other manufacturers apparently have similar plans to at least increase the percentage of their notebooks sold with LED notebook backlighting in 2009 and 2010.
The company predicts that the market for LED Driver ICs in notebooks will reach over $50 million in 2010. Company News Release,

DisplaySearch Predicts 300% Increase in LED Units for Backlighting from 2008 to 2012 LIGHTimes News Staff
June 23, 2009...Market research firm, DisplaySearch predicts that in 2012, 34 billion LEDs will be used in TFT LCD backlights, in sizes ranging from 1” to more than 70”. This is up more than 300% from 8 billion in 2008, according to the new DisplaySearch report, "Display LEDs: Lighting Up the Display World".
DisplaySearch says that a total of 70.8 billion LEDs were shipped in 2008. The company breaks down its statistics into two categories of LEDs used in display applications; active outdoor displays, which used 11 billion LEDs or 15% of the total in 2008, and LCD backlights, which consumed 8 billion or 11% of the total. The company further separates LCD backlight applications into five key types which it says are adopting LEDs: small/medium, notebook PC, desktop monitors, industrial applications, and most notably TV.
DisplaySearch says that in 2012, LED lighting for displays will make up the largest market segment for all LEDs at 34.7 percent. According to the company, this includes 34 billion LED backlights and 24 billion for active outdoor displays.
DisplaySearch forecasts that low-current LEDs will be the mainstream type used in large-area LCD backlights, due to cost, thermal management and luminance efficiency requirements. High-power LEDs, with a driving current higher than 350 mA (more than 1W), are not well-suited for LCD backlights due to thermal issues, and will mainly be used in general lighting applications that require high brightness.

Commentary & Perspective...
When it comes to LEDs, Korea wants it and Taiwan gets it Tom Griffiths - Publisher
June 18, 2009...After a whirlwind 6 weeks that included Light Fair in New York, and trips to
both Korea for their annual LED Expo, and Taiwan for our own Blue 2009, it's
fair to say that the solid state lighting revolution is underway, but in different
ways in different places. We'll all grant that the "brass ring" that
everyone on the LED merry-go-round is grabbing for is the general lighting market,
but the volume is being driven by other applications, and in visibly different
ways in the US, Korea and Taiwan.
In Korea, the LED expo is held concurrently with the flat panel display expo,
and that pretty much tells the story of what's driving things there. The big
guys in FPDs, LG and Samsung, have taken the downturn as a market-share buying
opportunity, both to move their product lines rapidly towards LED-based backlighting
as well as to build out LED manufacturing capacity of their own. Backlighting
has been a consistent winner in market performance the last few years, driven
by marked increases in sales of LED-enabled mobile appliances, notebook computers
and displays. According to Bob Steele of Strategies Unlimited, who provided
a mid-year update at Blue 2009 in Taiwan, mobile appliances and signage/displays
accounted for 60% of the US$5.1 billion packaged LED worldwide market numbers.
While standard handsets remained the volume king despite a slight decline, the
"other" category, which included smart phones/PDAs, media players
and notebook displays turned in an astounding 93% growth from 2007 to 2008.
Korea sees that as an opportunity to leverage up their domestic LED production
and has reportedly been heavily investing in the fabrication equipment, including
MOCVD reactors, which they need to make it come true. One speaker, from the
Ministry of Knowledge Economy, stated that it was Korea's goal to place itself
in the top 3 of LED producing countries in the world. "The competition"
in his view, was not a series of companies, but a series of countries, and I
suspect that neither the US, Japanese, or Taiwanese LED manufacturers plan to
step aside and let it happen. (China wouldn't seem to be sitting on the sidelines
either, based on the continuing series of news releases from epi-reactor maker
Aixtron, regarding their China wins, including their largest single order ever
coming out of that country from a company just entering the HB-LED market).
As one element of that "grand plan", in April of this year, Samsung
formed a dedicated LED company, equally capitalized by both Samsung Electronics
and Samsung Electro-Mechanics (SEMCO).
The ministry speaker also made it clear that he felt that the recent resolution
of several major pieces of IP litigation involving Seoul Semiconductor effectively
cleared the path for the continuing growth plan, as well as shaped the Korean
government's resolve to involve itself in future litigation that other of the
country's producers may encounter. In one curt exchange, the ministry official
made it clear that he felt that smaller companies should look towards sharing
IP to keep from diffusing the country's efforts, and that anyone who felt differently
was "carrying forward a myopic view of the future". As we heard from
Prof. Moo-Whan Shin of Myong Ji University in his "Korea country report"
at Blue, the government is putting its money where its mouth is in other areas,
including a big push for LED lighting in government facilities. The plan is
to begin by moving Korea's post offices to all LED lighting starting immediately,
and ban any incandescent lights in government offices starting this year (fluorescents
are still allowed... for now). Another 300,000 "projects" are ready
to be undertaken at the state and local level, and the goal is that 30% of the
government's indoor lighting is generated by LEDs by 2012. They are serious,
but LEDs manufacturing isn't new to either LG or Samsung, and as one senior
exec at Blue noted, "They haven't managed to consistently use internal
sources for LEDs in the majority of their products so far, so do we need to
worry?"
Taiwan is providing a contrast of "quiet action" in some respects.
Having typically been limited to Taipei and the LED heartland of Hsinchu, we
decided to undertake a bit of a broader "eyeball survey" of where
LEDs are showing up in Taiwan. To that end, after completing Blue in Taiwan,
we rented a car to tour around the eastern side of the island, with a return
trip through the mountains, and up one or two major expressways that connect
the north and central parts of the country. And yes, for those familiar with
the driving style in Taiwan, we really did drive it ourselves, making use of
every bit of "shoot for the hole" snap that our rental VW Passat Turbo
had to offer. Decoding street signs was a small challenge (Jhung, Chung and
Joung are just some of the different English spellings for just one Chinese
character), not clipping the scooters in Hualien and Hsinchu were a bigger challenge,
and shooting through a few hundred kilometers of winding, wet, tunnel-laden,
landsliding 1 or 2-lane roads in a path from sea level to 3300m (11,000 feet)
pretty much defined insanity. The car didn't get returned clean, but it was
undamaged and passed more cars and trucks than passed it (although we were memorably
humbled by one amazing truck driver who navigated his rig down a mountainside
with the skill of a Formula One driver, leaving the Passat in the dust... well,
actually in the mud spray, since the road was wet and I will stick with that
as my excuse).
Of note in the trip from the LED standpoint? Well, Taiwan "gets it".
There was not a city strip that wasn't featuring a substantial number of LEDs
beckoning you to stop in to buy something. The department stores almost exclusively
used LEDs in the jewelry display cases, and notably for a portion of the overhead
lighting in the more difficult to maintain or high liability areas, including
the escalators. Outdoor LED signs and displays were prevalent (I think we have
something like 10 here in Austin), and interestingly, LEDs were used for direct
illumination of a number of advisory, caution and exit-type signs on the main
expressways. What a good idea. Why use fairly expensive lighting-quality LEDs
to shine at a road sign, when you can use multiple colors of lower lumen devices
to make up the outline and information on the road sign? And the LED presence
wasn't limited to the expressways and big towns. Once we came down off the mountain,
we were greeted by LEDs in front of shops and in road signs in the surrounding
smaller resort towns. LED heaven itself appeared when we needed to grab some
fuel at one of the freeway service centers. It seems you don't need to just
expect gas and some fast food, but 24-hour mechanic services, and a shopping
megaplex, including entertainment and restaurants. All without ever touching
a side street.
We haven't been to Japan yet, but clearly Taiwan and Korea (as well as mainland
China) are ready and willing to adopt LED technology everywhere it can fit,
whether that is in a fancy jewelry display case, or to replace the oversized
CFLs that filled the portable generator-powered "night markets". With
a manufacturing ramp-up benefiting from the big backlight producers, both in
Korea and Taiwan, who will likely produce LEDs for both internal use and external
sale, the pricing curve will continue its move in the right direction to support
that adoption. If there is a missing link in those markets, we expect that it
will be in understanding how to address the quality issues in general lighting,
both in terms of design reliabilty as well as in the quality of the light produced.
There is no lack of ability to produce quality when its the need is understood,
such as in backlighting (how many loyal customers do you develop if you are
Samsung and customers start to report the need to replace their 60-inch TV because
the LEDs start dying in a year?). Understanding what quality is, and then designing
it in to a general lighting product, is a substantial challenge those regions
will face, which is one reason we're making that a principal goal for the 2009
SSLdesign
Summit Taiwan this November. (For the September NY
Summit, as well as October's LA
Summit, the spotlight will only be shining on the manufacturers and enabling
technology providers that are demonstrating quality in their products,
but that is more to indicate where and how quality can be found, and
less on what defines quality in the worldwide lighting market). From
what we see, things remain bright and will continue to get brighter.
