LEDs Magazine: US DOE releases new report analyzing LED-based SSL savings potential

Over two decades, LED-based SSL deployment could generate $120 billion in energy savings assuming products achieve forecasted performance objectives.
The US Department of Energy (DOE) has released a new report that analyzes the potential energy savings of broadly deployed solid-state lighting (SSL) sources – predominantly LED- and OLED-based products. The DOE projects that between 2010 and 2030, SSL could save 1,488 terawatt-hours representing a savings of $120 billion at today’s energy prices.The DOE has taken an active role in supporting and funding SSL lighting both to achieve energy savings and to position the US as a global leader in SSL technology. This latest report updates previous projections the DOE made in SSL lighting over the last decade.

The multi-faceted reports begins with an examination of lighting inventory and lumen demand. It continues with a look at the installed base and the technology improvements in conventional light sources.

The LED-centric content examines the improvements and cost savings expected in SSL over two decades. For instance, the report projects efficacy improvements. In high CRI (76-90) SSL lights, the DOE expects efficacy to go from 64.3 lm/W today to 147.3 lm/W in 2020 and to 176.3 lm/W in 2030.

From a cost perspective, the DOE projects SSL to go from $169.49 per klm today to $5.03 per klm by 2030 for high CRI products. The report makes projections for other CRI ranges and for OLED lighting as well.

The latter portion of the report focuses on projected market penetration and energy savings calculations. The analysis attempts to take a balanced view on the gradual replacement of technologies such as fluorescent with SSL alternatives.

The conclusion as stated up front is certainly impressive. The DOE expects SSL to completely displace all other technologies in commercial, residential, industrial and outdoor segments by 2030. The projected savings, however, come primarily from the replacement of fluorescent and halogen lamps in the commercial sector.

The DOE report claims SSL can reduce greenhouse gas emissions by 246 million metric tons of carbon over two decades. The full report is available on the DOE SSL web site.

LEDs Magazine: Dorsheimer chronicles LED market cycles at Strategies in Light

19 Feb 2010
Backlighting is the driving force in the current second cycle with general lighting poised to drive the third cycle.
Jed Dorsheimer, Principle Senior Equity Analyst at Canaccord Adams, presented an overview of the high-brightness (HB) LED market at Strategies in Light, defining the market by application cycles. Dorsheimer projected a bright near term outlook driven by the LED-backlit TV market.Dorsheimer predicts that LED penetration in the TV backlight market will hit 74-85% by 2012. He believes that the industry will experience significant under capacity beginning this year and a 70 to 100 billion LED deficit by 2012. That said Dorsheimer also predicts a cyclic market that will ultimately experience over capacity as well. But the TV market will help to enable a third boom cycle driven by lighting. He stated, “Lighting demand could go from 5 billion LEDs to 30 billion in one year.”

Canaccord Adams LED supply projection

The first cycle for HB LEDs began with mobile handsets in the early 200s according to Dorsheimer. First the LEDs were used to illuminate keypads and later to backlight color screens. That led to a surge in LED manufacturing and over capacity by the 2004/2005 time frame.

Still the LED performance improvements and declining prices driven by the first cycle enabled the backlight market cycle that was started by Apple with the Macbook Pro and is now driven by TVs. Based on the ramping TV market, Dorsheimer believes the LED manufacturing industry needs to add 515 to 780 more MOCVD reactors through 2012. And independent of the tools, Dorsheimer believes a sapphire shortage could still impede adequate supply.

So what happens beyond 2012? Dorsheimer believes current trends will lead to a 30% overbuild for the TV market. That will yield a surplus of as many as 60 billion LEDs, and what Dorsheimer calls a “one to two year digestion period” in the 2014 to 2016 time frame with little capacity growth. Once again the price declines and performance gains made in LEDs will help enable the third cycle driven by lighting.

Canaccord Adams LED residential payback

Dorsheimer also discussed obstacles to LED adoption in the lighting space. He points out that the actual cost of the LEDs remains significantly too high. In current LED-based replacement bulbs, Dorsheimer claims that LEDs account for as much as 40% of the bill of materials (BOM), and that’s despite the fact that the bulbs require a power converter printed circuit board and robust heat sink.

Today, Dorsheimer estimates the LED portion of the BOM at $25. He believes that number needs to drop to $4 to enable a $10 retail price for a 1000 lm bulb. The cost is critical because in residential applications Dorsheimer estimates the current payback time for an LED bulb to be 11 years relative to a CFL bulb.

Dorsheimer also discussed how the industry might get to lower prices. He sees a move to larger wafers as key. He predicts a move from 2-inch wafer to 4- or 6-inch wafers because the larger wafers offer better thermal stability and ultimately better yield. Dorsheimer stated, “Yield trumps all in this industry.”

Canaccord will offer more details on the third cycle later this year. Dorsheimer believes that lighting could consume more than 100 billion additional LEDs by 2020.

LighTimes: DisplaySearch Forecasts Steady Decline in LED TV Backlight Premiums

February 19, 2010…DisplaySearch predicts that the difference in cost between LED backlights and conventional cold cathode fluorescent backlights for LCD panels and sets is steadily decreasing. DisplaySearch says its Quarterly LED & CCFL Backlight Cost Report covers backlight unit cost structures and trends, with detailed cost breakdowns for 17 different configurations of notebook backlight units from 10.1” to 17.3”, 21 configurations of monitor backlight units from 15.6” to 27.0”, and 27 configurations of LCD TV backlight units from 26.0” to 60.0”.The newly-released DisplaySearch Quarterly LED & CCFL Backlight Cost Report, which analyzes and forecasts the cost structure of CCFL and LED backlight costs, disclosed that the average cost of 40” edge LED backlight unit in Q1’10 is $118, and will fall to $100 by Q4’10. The company points out that most LCD panel and set makers are focusing on development of LED (light emitting diode) backlight units for improved visual performance, thinner form factor, and lower power consumption. The key issue has been reducing cost, in absolute terms and relative to the conventional CCFL (cold cathode fluorescent) backlights.

LEDs Magazine: Steele presents bullish view on HB LEDs at Strategies in Light

16 Feb 2010
LED backlights lead the way in 2010 LED market forecast with total high-brightness LED market predicted to surge 53%.
Bob Steele, Director of Optoelectronics at Strategies Unlimited, took the stage at Strategies in Light and presented a market forecast for the high-brightness (HB) LED component segment. Next year, indeed the next five years, look very positive for the segment with the backlighting application leading the charge now and general lighting coming on increasingly stronger throughout the forecast.

The forecast focuses on the market for packaged LEDs. Overall, Steele predicts a 53% surge in the LED market for 2010 to a total of $8.2 billion. Through 2014 he predicts a 30.6% CAGR ramp to $20.2 billion. Steele stated, “We have not ever seen this type of growth in this market.”

Steele’s talk took both a look back at what happened in 2009 as well as projected the market looking forward. Last year, Strategies Unlimited predicted a 5% decline for 2009. And during 2009, a number of typically strong markets such as automotive struggled mightily as consumers simply didn’t buy cars at the normal pace. Indeed the auto segment of the LED market was down 18% in 2009 according to Steele.

As it turns out, the LED market actually rose 5% in 2009. A surge in LED-backlit LCD TVs saved the day reversing in the second half of the year what had been an overall decline in the first half. The signs and display segment, of which backlights are a part, grew 17.5%. The backlight segment is sufficiently strong that Steele indicated it will be broken out as a separate category going forward.

In other applications, the general-lighting segment drove the greatest growth at 24% for packaged LED sales. But Steele pointed out that the growth came from a very low base. Mobile appliances drove a modest 2.8% rise in LEDs sales, but is the largest application segment for HB LEDs. And that segment will benefit from the ongoing transition in the consumer space to smart phones.

In terms of the actual LEDs used, medium-power LED sales soared 152% as the TV makers primarily used this class of LEDs. Previously, the auto industry had been the primary user of such products according to Steele.

Looking forward, Steele predicts the surge in backlighting will continue. He pointed out that some analysts have projected the market as high as 39 million LED-backlit TV sets for 2010. He states, “We believe 22 million is more realistic.” The potential obstacles include both the price premium that the LED-based TVs carry and the potential shortage of LEDs to supply the market.

The notebook display and LCD monitor markets will add to the backlight market ramp. In notebooks, 50% of the products sold in 2009 used LED backlights and that number will climb to 80% in 2010.

General lighting is of course the other segment with the potential for huge growth. As a whole, the lighting market was down 15% in 2009 mainly due to the decline in the construction market according to Steele. But as mentioned earlier, the LED market for lighting grew 24%.

Steele projects a 32% uptick in the LED lighting segment for 2010. For the near term looking out five years, replacement lamps for the retrofit market will dominate according to Steele with smaller growth for new LED luminaires. He predicts a 44% CAGR for the next five years for LEDs in lighting.
