The famous Moose rules also apply in LED industry. The price of LED lamps is continuing going down as the development of the technology. In Europe, it is reported that the price downtrend of warm white LED light bulbs for 40W and 60W replacement (40W bulb and 60W bulb) persisted in August 2011. The ASP of LED bulb for 40W bulb took the most severe dip, plunging to US$ 23.5 with a 4% decline compared to July this year; the ASP of LED bulb for 60W bulb dropped to US$ 43.8, a 1% decrease compared to July this year. The European and American markets underwent the most drastic downturns.
The ASP of LED bulb for 60W bulb dropped to US$ 43.8, a 1% decrease compared to July 2011. While the ASP in the United States took a significant dip of 5%, the ASPs in the rest of the world remained relatively stable. On the other hand, the ASP in the United Kingdom slightly rose due to the exchange rate factor.
In August, the LED bulb price in Europe experienced the biggest hit, with the ASP of LED bulb for 40W bulb fell by 11% (19% if the exchange rate factor is not taken into account). Although the LED bulb price drop in Europe was sharper than other parts of the world, the ASP of Europe’s LED bulb remained higher than other regions, averaging US$ 29. In fact, the ASPs of LED bulb in Japan and the United States dropped by 4% and 1%, respectively while the ASP in South Korea fell by 2% due to the exchange rate factor.
The average price for 40W bulb in Aug’11 declined to US$ 51/Klm, while the price for 60W bulbs dropped to US$ 54/Klm. It is believed that by 2012, LED light bulb price will become more affordable for consumers. Benefiting from bans against incandescent lamps, LED lighting market will see a significant growth in 2012.

Chinese LED Makers to Cut Production and Downsize, Helping Industry Break Free From Price Wars and Move Towards a Better Future
According to a survey, the revenues of listed Taiwanese LED manufacturers amounted to NT$ 8.415 billion (MoM-2.69%, YoY-18.9%) in Aug’11. Due to steep drop in the LED price, the demand side has been striving to lower the component inventory levels. However, the impending demand surge triggered by Christmas holiday and the new models of LED backlit TVs will most likely cause the rush-order effect for the backlight market, providing a timely and welcomed break for LED manufacturers.
The survey indicates that the oversupply will continue to hover around the LED lighting industry in the next few years. In light of the unfavorable market outlook, Chinese LED chip makers have put their expansion plans on hold – a number of manufacturers have delayed production plan, postponed MOCVD installation plan and even considered exiting the market. Therefore, the survey estimated the number of new MOCVD equipment installed in China in 2011 at less than 400 units, which is expected to have a positive impact on LED lamp price in 2012. Moreover, as the competition in the LED industry intensifies, Taiwanese manufacturers’ fast responses to the changing economic climate give them a better chance of making inroads into the global LED industry. Big factory with enough cash flow can better survive in these two years.

LED Lamps, Their Future is Really Bright! (4)
According to the DOE, rapid progress will continue as the agency, along with its industry partners, pushes this technology to its efficiency limit, which is expected to be reached by about 2015. Properly designed LED luminaires will achieve efficacies of about 138–188 lumens per watt or LPW, or 10 to 14 times that of incandescent lighting. In addition, the DOE expects that LEDs will continue to fall in price as new and better ways to package and manufacture them are perfected.
Contractors should not underestimate the effect that LEDs are going to have on future projects. According to Hamburger, a February 2011 solid-state lighting fixture report from Strategies Unlimited, predicts that the LED lighting market will grow to $8.3 billion by 2014, with a CAGR for the solid-state luminaire market to be 21 percent from 2010 through 2014. The report, “LED Luminaires Market Analysis and Forecast Second Edition 2011,” states that improvements in performance and the price of commercially available high brightness LED packages, heightened concerns regarding energy efficiency, and the phase out of incandescent lamps, have combined to create favorable conditions for acceptance of the technology.
Based on multiple market analyses and proprietary, internal growth rates, Briggs expects the LED lamp market to grow 50 to 65 percent over the next three years, which by anyone’s reckoning should translate into a great deal of LED work for electrical contractors. And while Toshiba wouldn’t share any specific numbers, DallePezze said that the company is so confident that LEDs will become the prominent technology in the lighting market within five years that it stopped making incandescent sources a couple of years ago.
The debate really can end; there’s no longer any doubt that the future will be an energy-efficient one, and LED lighting are certain to play a pivotal role in achieving it. The technology’s few remaining limitations will be surpassed soon, and LEDs will be widely adopted as the light source of choice by a cross-section of society. Electrical contractors should be on the leading edge of that wave.

LED Lamps, Their Future is Really Bright! (3)
When CFL is first introduced to the market, its performance disappoints many electrical contractors, so when LED Lamps are introduced now, it is very natural that the electrical contractors is somewhat hesitant to believe what they claims. But his time, the story is really different.
“The responsibility is on manufacturers to educate the chain and create demonstrable examples that show the benefits of the technology,” Hamburger said.
Manufacturers are ready to educate electrical contractors, distributors and product end-users about what LED technology is and what it can really do. Can LED fluorescent tubes really replace traditional tube although the traditional one has some many disvantages?
Contractors can look to the lighting industry to adopt a “try it before you buy it” philosophy to help overcome any resistance to LED technologies, DallePezze said
DallePezze’s recommendation to contractors is to try LEDs in appropriate applications, such as install LED spotlight in bathroom and see how they perform. “Just make sure to do the research that ensures a quality product is being used,” DallePezze said.
Testing and lighting standards, such as IESNA’s LM79 and LM80, are already available and can ensure contractors that they are purchasing the proper, reliable product for the installation, while the National Electrical Manufacturers Association has issued several standards and white papers covering LED drivers, dimming and binning.
“But if long-life, energy-efficiency performance and color are the most important criteria for fulfilling the end-user’s requirements, then LEDs are certainly ready to replace traditional lighting sources,” he said.

The biggest knock against LEDs is probably the cost. Right now, the upfront cost of LEDs in general illumination is admittedly significant but, according to DallePezze, can be acceptable, depending on the building’s or consumer’s current energy costs and usage.
“In the near-term, a LED lamp that is equivalent to a 60-watt incandescent in terms of output is going to be more expensive. But price is already less of a consideration in those applications, with higher energy costs and always-on considerations, and it will be dropping consistently and significantly over the next three years,” he said.

But price is already less of a consideration in those applications, with higher energy costs and always-on considerations, and it will be dropping consistently and significantly over the next three years,” he said.
Hamburger agreed that pricing is already becoming less of a consideration because LED fixtures such as led spotlight provide quality and performance that is as good or better as traditional lighting.
“Businesses and consumers are at the point where they are looking beyond just price as the ultimate decision-driver and are seriously considering LED technology for its sustainability aspects as well as for the incentives and rebates that are helping to accelerate acceptance,” he said.
In the professional channel, Briggs said, life cycle and payback are more of a consideration than price.
“When payback reaches less than two years, the product in question gains mainstream acceptance,” he said.
To address issues of cost, the Department of Energy recently issued 17 solid-state lighting grants. The agency will put $10.3 million into product development to refine them to be more functional, market-friendly and commercially viable. And for the first time, the DOE’s solid-state lighting grants will include $23.5 million to invest in a manufacturing category. Collectively, these grants seek to drive down costs while improving quality and developing new product-making techniques. The chosen companies will also chip in large sums of cash on their projects, bringing the whole solid-state research program to more than $66 million.
Problems revolving around the color of the light generated by LED fixtures seem to be mostly resolved. Hamburger pointed out that LED tube or LED bulbs already achieve as good or better a color point from product to product as other modern lighting technologies. In the future, he believes manufacturers will develop even more color point and color rendering index (CRI) combinations that provide further options for the consumer.
“For example, workers could use LED fixtures to design personal lighting schemes in their office spaces,” he said.
LEDs are already achieving a level of 90 on the CRI, and Briggs expects products that reach 95 CRI to hit the market by 2012.
“Even today, custom binning or special recipes will achieve 95 on the CRI scale, which is better than both linear fluorescents and CFLs. Only halogen, at 100, outperforms LEDs in this area,” he said.
In the realm of controls, bilevel occupancy and motion sensors for LED fixtures are being developed, and in some places, such as California, it is already legislated that certain outdoor fixtures include the technology. For indoor applications, Hamburger said, pilot studies are being performed on ambient lighting controls for LEDs that will enable sensors to optimize the use of natural light and control fixtures’ outputs according to those levels.

Peru's stadium façade lighting responds to football fever
A very interesting product is delivered these days. Have you ever imagine that the LED lighting system can reflect how the audience is? Yes, it truly can be done.
Cinimod Studio, a London, UK-based architecture and lighting design firm, has delivered an interactive lighting-control system for the Peru National Stadium in Lima. LED flood light. The system gathers the crowd’s noise levels in real-time and translates the audible signal into a visual map that is depicted on the façade’s lighting display.
The façade-lighting system begins with a network of customized microphones deployed along the stadium’s roof line. LED bulbs. This data is then processed by Cinimod’s custom processing hardware and software located in the stadium’s main communications room. The audible data is analyzed using mathematic calculations and self-calibrating algorithms. The software then communicates a “mood state” to the e:cue lighting controller, which transmits the relevant DMX control signal to the lighting fixtures on the building’s facade.
The external lighting scheme is designed to integrate seamlessly within the architectural framework of the building. LED fluorescent tube. The majority of the lights are laid out as fans of flames that wrap upwards around the form of the structure. The façade’s patterns vary in color, speed, brightness and scale.
The main mood states include: 1) Boring, a neutral mood; 2) Excitement, accompanying a surge in crowd noise and pitch; 3) Celebration, typically triggered by a goal and followed by a further rise in noise level; and 4) Disappointed, triggered by an excited state followed by a rapid decline in noise level.
The software runs perpetually, constantly evaluating the mood, which varies between celebration at one end of the spectrum to disappointed at the other.
The scale of the stadium façade necessitated a very large array of color- and pixel-addressable fittings. The lighting controller provides 62 universes of DMX lighting control output
Is it really interesting? Maybe one day they can produce a mini version so that we can also install this system to reflect our mood at home or in the office. Market is there, the bosses will love it.

EPA finalizes guidance for lumen maintenance of LED subcomponents
Industry standards can always help the related industry developed better and better. Recently, a new standard in the LED lighting industry was released. The US Environmental Protection Agency (EPA) has finalized guidance regarding the content and application of lumen-maintenance performance data for LED packages, LED arrays and LED modules that are intended for use in Energy-Star-qualified solid-state lamps and luminaires.
The objective, says the EPA, is to facilitate robust testing which builds upon industry best practices and helps maintain confidence in Energy-Star-qualified lighting products. LED spotlight, EPA developed this guidance in consultation with LED package and array manufacturers.
A cover letter sent along with the guidance document is copied below:
This guidance relates to subcomponent-level performance data and addresses topics not explicitly covered in Energy Star lighting specifications because of the quickly evolving nature of SSL technology, including: the content of IES LM-80-08 (“LM-80”) test reports, case temperature measurements, sample set correlated color temperatures, successor (next generation) devices, and LED array testing.
A draft was distributed on June 24, 2011 for stakeholder review. LED flood light. The feedback received by EPA in response to the June 24 draft focused on three primary topics:
In addition to the above, language was clarified regarding color-temperature tolerances, subcomponent model and series numbers, and LED array substrates. LED lamps. Reporting requirements included in the Luminaires V1.1 specification were added to section 3.2 for consistency. EPA intends for LM-80 testing and reporting to follow this guidance going forward, while providing allowances detailed in the guidance for testing and reporting already completed, as well as testing which is currently underway or in the final planning stages.
The Agency recognizes that this technology is rapidly evolving, and that the SSL industry is in the process of working towards consensus on some outstanding technical issues. Due to the rapidly changing nature of the market, while this document is final, EPA will continue to track progress and testing results to determine when changes to this document are necessary
