Zhangjiang, Shanghai high-tech enterprises to gather. Shanghai Semiconductor Lighting Engineering Research Center here and inconspicuous.

But when the "Science Times" reporter in-depth interview after the discovery, popularization of LED lighting in China may be the hope of a breakthrough from here.

Changes to the platform from the stage

Compared to the hustle and bustle during the day, the Expo is even more evident at night near a distance to see the beauty of tilapia, in addition to "a four-axis Hall" and the Urban Best Practice Area, the park plaza lighting, along the landscape, identity and smart guidance systems are used semiconductor lighting technology. According to preliminary estimates, the entire park LED chips more than the amount of 10 billion, more than 80% of the park's night lighting with LED technology. Can be said that the Expo site has become the world's largest LED demonstration area.

Is a new solid-state LED light source, a small size, low power consumption, long life, fast response, high reliability, has been recognized as a world, the importance of energy saving lighting, materials, and to expand up to speed fast kinds of applications. Currently, the semiconductor lighting has become a national competition in the field of energy-saving technology focus. Internationally, the high-end LED technology continues to progress, with each passing day.

Recently, the "Science Times" reporter learned during an interview in Shanghai, with the opportunity for the World Expo, Shanghai's semiconductor lighting Industry Has been a spurt of development, a group of national business development and growth momentum.

China in 2003 Science and Technology Relevant ministries and local governments jointly set up National Semiconductor Lighting Project Coordination Leading Group, officially launched the National Semiconductor Lighting Project, Ministry of Science and Shanghai became the first approved four national semiconductor lighting industrial bases.

Chinese Academy of Sciences Technical Physics researcher Wei Lu believes that Shanghai World Expo, once again promoting the Shanghai LED industry chain development, and in the post-World Expo era, Shanghai should start LED stage show developed into a true development platform for Shanghai semiconductor lighting industrial technology level to improve and promote Shanghai semiconductor lighting industrial scale development.

Shanghai Engineering Research Center for Semiconductor Lighting Guo Yansheng, director believes that the support of national policy in Shanghai is leading the LED industry, the progress of the country. He said that China is a manufacturing country, semiconductor lighting industry has an unparalleled advantage in the downstream. After years of investment in Shanghai, in the upper, middle and lower reaches have cultivated a group of self-agglomeration Intellectual Property Enterprises, especially in the last 3 years, the Expo focused on a number of technology projects, the next goal is to white LED lighting into millions of households.

Incubator to promote the market

Shanghai Semiconductor Lighting Engineering Research Center in early 2005 by the Shanghai co-sponsored by 17 units set up base there are currently more than 300 enterprises, including Benjamin, think twice, blue, Sapphire is one of the best and other enterprises.

Through 5 years of efforts, the Shanghai semiconductor lighting of public R & D and services platform even better. On this platform, 7 sub-centers and five specialized laboratories dedicated LED products to establish technology, quality and safety standards (specifications) system for product selection of LED products used to provide the scientific side, convenient and uniform standards. Standards have been developed, including electronic detection LED light color standards, LED substrate material standards, LED chip test method standards, LED instantaneous flux test method standards, LED construction and acceptance of standards. Among them, the construction and acceptance criteria have been formally listed in Shanghai local standard, starting May 1 this year, the formal implementation.

This year's guide to science and technology research in 2010 also clearly stated the standard-setting work, as the focus of this year. However, the Shanghai Engineering Research Center for Semiconductor Lighting Feng Xiong, assistant director, said the industry update too fast, the basic 3 to 6 months after the performance there are significant changes, many standards have not yet worked out already out of date. "This is a problem emerging industries." He said.

Industry update speed, and more small and medium enterprises, how to promote industrial development?

On this issue, the Shanghai semiconductor lighting industry incubator Liman Ping, chairman of a profound experience: "We have projects in the organization found during the Expo, semiconductor technology, lighting design is very wide, each company has its own technical expertise, can not cover all. Imagine if there is a platform that can integrate expertise from various enterprises for the World Expo in Shanghai semiconductor lighting industry to contribute, it will be wonderful to pieces. "

Thus, the Shanghai semiconductor lighting industry incubator came into being. This is a transformation in order to promote scientific and technological achievements and train high-tech enterprises and entrepreneurs for the purpose of the technology business services center. Technical support under the market docking, shared network of professional and expert advice incubator 4. Through this platform, many SMEs are in this project, the Shanghai World Expo assigned to share.

Liman Ping told "Science Times" reporter, said that participating in projects such as the Theme Pavilion, the incubator companies are formed under the team to undertake the project, finally found a good effect.

"Set up semiconductor lighting incubator, the biggest job is to market-driven." Liman Ping said that many companies are relatively small, it is difficult for the market, it is difficult for government organizations, large projects. If the organization through the project to integrate enterprise resources, these enterprises will be able to undertake large projects. "This is an experience that left the World Expo." She said excitedly.

Large training through the Expo, a group of companies stand out in Line Has a certain reputation in the industry. Next, an incubator and industrial base linkage of the intention and the surface. "We're like a cradle." Liman Ping said, "want to develop stars entrepreneurs, support for enterprises through a variety of faster development. But our principle is that once they grow, and to leave the incubator space to help us provide better business continue to develop. "

Look forward to every household white light illumination

Landscape lighting is currently high domestic chip performance, but the indoor lighting and functional lighting is still lagging behind. China White LED home insufficient technical capacity.

However, the Shanghai World Expo Park, the main road all the steps made by the white LED lighting, saving energy consumption by 70%.

In the exposition of the "Shanghai Eco-Home", including outdoor landscape lighting and interior functionality, including all lighting, white lighting, LED lighting technology are used. Lighting, general manager of the ear on the pine Cao Dong believes that this indicates that functional white lighting into millions of households possible.

Guo Yansheng said that the future in Shanghai, shops, buildings, street lamps, tunnel bridges public works will be able to see more LED applications, such as Chongming Tunnel will be all-LED lighting. The white LED lighting will also be in 3 to 5 years into people's homes.

In fact, the current home of the market is not without LED product sales, but Liman Ping told reporters, consumers, the absence of specialized equipment is difficult to determine the time of purchase there is the problem.

The reporter was informed, in response to the World Expo, Shanghai semiconductor lighting engineering and technology research centers established a set of technical standards system and evaluation system products, services, World Expo LED product testing and evaluation, as the application of LED products to enter the Expo will provide access to services; this system after the Expo will also have to use LED products, evaluation mechanisms, optimization, add the appropriate standards.

Experts said that if this system of promotion, will be able to LED product life, reliability, energy saving, safety, rationality and other aspects of assessment, to determine market access, and promote the healthy development of LED industry.

White LED lighting is the main trend of the future

White LED lighting is the main trend of the future

In many families, institutions, government and industrial applications, high brightness (HB) White LED (LED) is rapidly replacing incandescent lamps. In the past year, the white light LED Lighting System in general lighting applications accounted for more than 50% more than the final color LED applications, application of colored LED lighting, mainly by the beauty of color demand-driven. Growth of white LED lighting, new drivers is simple: lower energy consumption result in lower tariffs.

In many cases, LED high efficiency can reduce power consumption by up to 88%. They also greatly reduce the lighting and power generation and transmission of electrical energy caused by carbon dioxide emissions. According to research firm Strategies Unlimited, 2012, the total high-brightness white LED lighting market is expected to exceed 50 billion dollars, corresponding to the 2009-2012 compound annual growth rate of 28% (CAGR). This is just the beginning, because the LED luminous efficiency continues to accelerate the commercial / residential lighting market from incandescent, fluorescent and high-pressure sodium lamp with high brightness white LED to change at the same time, LED or even from a commercial point of view has become more cost-effectiveness.

According to some calculations, shifted from traditional incandescent and fluorescent lighting, LED current global total energy consumption could save up to 10%. With accelerated efforts to reduce the total power generation of carbon dioxide emissions, global lighting energy demand by 10% of the potential of this shift played a great role.

Linear Technology Product Marketing Engineer Jeff Gruetter

What factors support such a huge growth potential? First, the current generation of LED luminous efficiency 10 times higher than incandescent, fluorescent and high pressure sodium lamp is (HPS), more than twice, thus greatly reducing the necessary light output (measured in lumens) the necessary power. With the further development of LED, which depend on the efficiency of electric light will continue to increase, and is expected to double within the next few years.

Second, in a very environmentally conscious world, LED lighting does not need treatment, contact and remove the toxic fluorescent mercury vapor in common. Today, most residential lighting systems for cold cathode fluorescent lamp (CCFL) with up to 5mg of mercury, which contain more mercury lamp much more!

Third, the incandescent lamp with 1,000 hours each to replace, and sustainable use of fluorescent lamps up to 10,000 hours, compared, LED life over 100,000 hours. In most applications, this allows LED permanently embedded into the final application, without attachments.

Examples include commercial and residential indoor and outdoor lighting, such as street lamps, industrial lighting, and indoor and outdoor such as power plants and refineries and other hazardous environment lighting. Some applications (such as refinery) run 24 hours a day, LED will continue to use up to 11 years, which means they will need replacing. In addition, LED lighting than other types of several small and flat digital level, can create a very flat form factor, so they can be permanently placed in the internal and external applications.

New York, by the high brightness LED lighting of the bridge.

LED's small size also makes LED into the reflector housing can be made more sophisticated, and thus more efficiently focus light. White LED provides pure "full spectrum" white light, there is no gap in chromatography, leading to the need for reliable visual acuity tasks, we can very easily see it. For example, see color wire, colored flags read or distinguish between water vapor and smoke caused by fire. In contrast, high pressure sodium orange light environment to accomplish the same task may be difficult, because in this lighting environment can not accurately distinguish between colors.

With the human eye can detect changes in comparison to, LED but also to a much faster rate of dimming and on / off, which greatly reduces power consumption. LED lighting can be dimming or off, until they are needed, and then immediately switched to the maximum intensity, and fluorescent or high pressure sodium lamps take up to 30 seconds or longer to reach maximum intensity.

However, the lighting system is one of the biggest challenges facing designers is how to optimize all the benefits of the latest generation of LED. Because LED usually need an accurate and efficient DC current source and a dimming method, so LED Driver IC must be designed in a variety of applications to meet those needs. Power solutions must be efficient, robust, very compact and cost-effective. Can be shown to drive lighting from incandescent, fluorescent and high pressure sodium lighting to LED array change, the fastest growing application will appear in the general internal / external lighting applications, because in such applications, the power to save the return is the largest.

Such as small size, long life, low power consumption, easy to transfer the benefits of light and fast turn time has accelerated the high-brightness LED lighting in the industrial and residential lighting applications, and many have been adopted. LED's long life and small size makes the introduction of new applications in a variety of configurations possible, these applications include in the refrigerator white LED lighting in front of the array, as well as illuminate the more complex the entire campus system. Figure 1 below shows the New York Verrazano Narrows Bridge, the bridge entirely by the high brightness LED lighting. LED high efficiency greatly reduces power requirements, and their long life and durability in a relatively harsh marine environment is particularly important.

LED lighting, "Dress" Asian Games

LED green lighting was strongly advocated, in addition to the Expo will also Dress up Dress up the Guangzhou Asian Games. 2010 Guangzhou Asian Games approaching, in order to reflect the concept of green Games, the Organizing Committee will use "green" militants to dress up the opening ceremony of lights in light effects, the number is expected to be 100,000. 16th Asian Games will be held November 12, 2010 to 27 in China Guangzhou. Is currently planning the opening ceremony were in full swing. To further demonstrate the concept of Green Olympics, when the opening scene, sea, sand around the green light will be enabled.

In addition, the Guangzhou city will also be extensive use of the species. It is understood that the Guangzhou municipal government has allocated 20 million yuan funds to support LED lighting industry for the promotion and use. At present, Guangzhou has been in four areas more than 40 sections of the city completed the main road and about the transformation of more than 8,000 street lamps in the country in the lead.

Further escalation of the surrounding landscape lighting

After 10 years of development, the brightness of the Guangzhou Pearl River project has begun to take shape. In order to meet the Asian Games, Guangzhou, the light works by means of its "East Wind" upgrade. Guangzhou Urban and Rural Commission invited experts on the axis of the Pearl River and the new light project developed a new planning scheme. Pearl River bright new projects planned total length of 18 km, extending eastward from the White Swan Pond Complex Bridge. Meanwhile, the new concern will be the axis of a night dream picture 5 km.

West Pearl River from the White Swan Pond light engineering, east Pazhou Bridge, across the Liwan, Yuexiu, Haizhu, Tianhe four districts, the total length of 18 km north-south. Will use the ocean, boat, sail combination of thousands of elements such as sails compete, vying for the theme, this implies the Guangzhou Maritime Silk Road used to be the starting point. Both sides, includes a new TVT ower, sea, sand, Xinghai Concert Hall, White Swan Pond, and other nodes of the night.

 

Comprehensive analysis of: LED landscape lighting development

Abstract: LED lighting the history of human revolution, the fourth LED is a semiconductor light emitting device, is recognized as the most promising in the 21st century high-tech products, one of the lead lighting revolution, but also to promote energy conservation , make a significant contribution to environmental protection. With strong government promotion and transfer of global industrial echelon, the future of the landscape lighting will be LED dance era.

Landscape lighting, people can not help but think of the total city's colorful, and bright lights of the clouds over the IPL and swayed. LED, the human history of the fourth revolution in lighting is a LED light-emitting semiconductor components, is recognized as the most promising in the 21st century high-tech products, one of the lead lighting revolution, but also to promote energy conservation, environment make a significant contribution to conservation. With strong government promotion and transfer of global industrial echelon, the future of the landscape lighting will be LED dance era.

Why is favored by the LED landscape lighting

(1) LED lighting has a huge energy-saving effect, the power LED only a single 0.03-0.06W, and low driving voltage (1.5-3.5V), current is small (15-18mA), the same lighting effect in the formation of the case, power consumption of only one-eighth of incandescent, fluorescent one half. LED light source instead of using ordinary visible light and fluorescent lamps for great landscape lighting power consumption, the energy saving effect is very obvious, with strong market competitiveness. And the LED light source 100 times the life of incandescent, fluorescent 20-30 times, eliminating the need for frequent maintenance of the pain, coupled with its rich colors and good controllability for the urban landscape lighting is better than this . Now, LED is the growth rate of 50% to replace the traditional light sources, lighting in the history of mankind will trigger the fourth revolution, greatly improve the human environment, alleviate the increasingly serious energy crisis in the world.

(2) LED light source structure of light (epoxy resin), small size, can adapt to a variety of sizes and different geometry of space, light is solid, not inflated, there is no gas sealing problems, no glass shell, impact resistance, vibration, not broken, determines its strength and stiffness of the lamp light source than other power requirements low. Moreover, LED is a cold light source, controllable, fast response time, can be repeated frequently light off, not tired.

(3) LED light source color pure, rich, any evolution of color than the color metal halide lamp, and its unique decoration. Compact LED light source, it's very good flexibility, can form a variety of point, line, surface, ball shape. According to the purpose of landscape lighting decorative landscaping, LED light source through the microcomputer intelligent control technology, the changes can be made suitable for point, line, surface, ball and other forms, including: flicker (flash) control, suitable for the formation of "points, lines "; gradient (soft variables) control for the formation of" surface "; dynamic change (jump) controlled the formation of patterns for vertical and horizontal dynamic changes. These three changes in the sphere of the rotation can also be formed, in addition to control and can be a single lamp light control group.

Of course, LED is not without flaws.

(1) LED more "precious", the excellent heat dissipation needs for support, constant current driver solutions such as support, improper use, prone to bad light or even "dead lights" phenomenon.

(2) a single LED, low power, in order to obtain high-power, require multiple parallel.

(3) LED color rendering index is low. The LED light color is not displayed under incandescent true, it came from the analysis of spectral distribution, a technical problem.

LED lighting, an increase of 500% investment in the Great Leap Forward

"In 2009, China's LED lighting, the penetration rate of less than 1%, but I estimate that next year will usher in a major outbreak, optimistic estimate or 5% to 10%. "December 14, 2010 is held in Guangzhou Asian Energy Forum, Shenzhen LED ("light-emitting diode," energy-saving lamps) president Wang Dian-fu Industry Association predicts that by 2015, LED lighting, or the penetration rate of more than 30%.
Global lighting giant Philips even more optimistic forecast, LED lighting, general lighting market in the world in 2015 the proportion rose to 50%, 80% in 2020. According to statistics LEDinside, 2009, the global LED lighting output of about 2.4 billion, only 3.3% penetration.

Wang Dian-fu said, according to the survey, plans to import the extension of the domestic manufacturers of furnace (MOCVD, the LED chip production equipment) for the 1466 platform, "What is the concept of this figure? Means this is the sum of the 2006 World MOCVD." As of the end of 2009, the world has been put into the MOCVD equipment, only 1,200 units. LED high-tech enterprise development, according to the National Committee of the forecast, the domestic LED industry in 2010 will reach 600 billion yuan investment, compared with more than 100 billion yuan last year, 500%.

However, this also led to excess investment in the industry on the LED industry concerns. China more than 3,000 LED business, not a company's market share of more than 2%, the annual output value of only 140 million, of which no one with annual sales exceeding 10 million.

An industry concern is expressed, the current domestic LED lamp products, light effect, lighting uniformity, color, life Dengjun there are technical problems of instability, especially the light failure are so severe in some cities The test results are not satisfactory.

A huge hidden dangers that most Chinese companies do not have the LED current core technologies, such as, LED chip technology is mainly controlled by Cree, Philips , Osram, Nichia and a few foreign hands.

"More serious is the issue of talents." Wang Dian-fu said that the current order of 1,466 domestic units MOCVD terms, need to more than 1,400 engineers, more than 100 leaders, but fell far short of the talent team building.

In Wang Dian-fu seems certain domestic enterprises to go LED Grow lights lean manufacturing path, "or to focus on quality and brand."
