Author: Photoelectric News Network has Cong
In early 2009, in order to expand domestic demand, promote the development of China's LED industry, and reduce energy consumption, the Ministry of Science and Technology of China launched the “Ten Cities and Ten Thousands†semiconductor lighting application demonstration city program, which covers 21 domestically developed cities such as Beijing, Shanghai, Shenzhen and Wuhan. city. The domestic LED lighting industry is collectively excited. According to the forecast, the LED street lights will increase by 178% in 2009 compared with 2008, with an output value of 1.625 billion US dollars. It is expected that the domestic LED street lamps are expected to reach more than 8 million in 2011, with a penetration rate of 8.5%. . What impact will the plan have on the various levels of the middle and lower reaches of the Chinese LED lighting industry? Will the LED industry bring out the gloom of the financial crisis? Behind the huge opportunities, what challenges will the national industry face? What countermeasures should we take? In response to various questions, Optoelectronics News produced the “Opportunities and Challenges Brought by the “Ten Cities and Ten Thousand Cities†to China's LED Industryâ€. The news topic invited a number of industry experts to influence the impact of “Ten Cities and Ten Thousand Cities†on China's LED industry. Multi-level, all-round discussion. The following is the opinion of Mr. Zhang Wenliang.
Zhang Wenliang, Manager of Qinshang Optoelectronics Brand Culture Department News: What impact do you think the “Ten Cities and Ten Thousand Cities†plan will have on the upper, middle and lower reaches of the LED industry? How long will this impact last? Is this impact already present?
Zhang Wenliang: The “Ten Cities and Ten Thousand Miles†plan and the “Thousand Miles of 100,000†plan in Guangdong will make China the world's largest LED street light market. So far, the state has approved 21 cities as the first batch of pilots. Due to the high industrial relevance of the semiconductor lighting industry, it has a strong pulling effect on new lighting, lighting, advertising, display, circuit, packaging, new materials, equipment manufacturing and other industries, which can drive the upstream and downstream electronic information industry. The development and acceleration of the development of the semiconductor lighting industry with independent intellectual property rights is of great significance for cultivating new economic growth points, promoting the optimization and upgrading of industrial structure, promoting sustainable economic and social development, and achieving energy conservation and emission reduction targets. This positive impact will stimulate the booming LED industry at home and abroad in the next two years.
It is understood that the LED street lamp market in 2009 was not affected by the economic environment. The domestic LED street lamp market is expected to grow by 79% next year under the favorable growth this year, accounting for more than 50% of the global LED street lamp demand. Driven by the domestic policy of expanding domestic demand, China's LED street lamp market will be held in Shanghai on September 22nd in the second international street lamp, garden lamp and outdoor lighting exhibition, including the British Lighting Association, the American Lighting Association, etc. The attention of the 15 international lighting organizations inside indicates that the period of strong development of the LED industry has arrived.
Optoelectronics News: How is China's progress in the development of LED-related standards (such as street lights)? What characteristics do you think this standard should have?
Zhang Wenliang: For the domestic development of LED-related standards, Wu Ling, secretary general of the National Semiconductor Lighting Engineering R&D and Industry Alliance, once pointed out: "The technology of semiconductor lighting is still at a mature stage, and the world has not been unified so far. Testing standards, so its market competition is relatively disorderly."
However, with the rapid development of the LED industry, the industry requires accurate measurement of the light, color, electricity and heat parameters of LEDs in order to facilitate quality control and product sales. Despite the rapid development of LED street lights, the standard of LED street lights is relatively lagging behind. Globally, LED street lights are not standard, and European standards like LED street lights are now available. In fact, the standards for LED street lamps in different regions are not the same in terms of indicators. The LED street lamps we have made must meet the requirements of the sales area in the standard. Therefore, the bidding LED street lamp project should thoroughly study the local LED street lamp standards. Will have a place in the fierce market competition.
As the national standard for the national standard of semiconductor lighting and the formulation of local standards, Qinshang Optoelectronics has participated in and formulated the national "LED Technology", "LED Lights for Decorative Lighting", "LED Lights for Road Lighting" and Guangdong LED Street Lights. And was approved by the National Standardization Administration Committee to set up the "National Lighting Appliance Standardization Technical Committee LED Lighting Device Working Group" to be responsible for the system and revision of the national standards for LED lighting devices.
The "Guangdong Province LED Street Light Local Standards" proposed and drafted by Qinshang Optoelectronics was recently approved by the Guangdong Provincial Bureau of Quality and Technical Supervision and decided to be implemented on July 1, 2009. This "Standard" was jointly drafted by 35 companies and related units such as Qinshang Optoelectronics, Tsinghua University, Dongguan Quality Measurement Supervision and Inspection Institute, South China University of Technology, Guangdong Lighting Association, etc., and integrated the opinions of other companies in the same industry, taking into account the current The objective status of LED development in Guangdong Province. The standards for data efficiency requirements such as light efficiency, light decay, life, temperature, etc. are mainly based on the national standard “LED street light for road lightingâ€, the actual application requirements of LED street lamps in Guangdong Province, and the 3 years test of Qinshang Optoelectronics. Actual measurement results.
This is the first time that Guangdong Province has formulated such standards, which is of great significance for regulating the Guangdong LED industry and promoting the development of semiconductor lighting technology in Guangdong Province. It not only meets the long-term development strategy of the enterprise, but also has important significance for improving the technical content and product quality of the entire Pearl River Delta LED enterprise, standardizing production and sales, and improving the competitiveness of the industry.
Optoelectronic News Network: Many countries in foreign countries have similar LED lighting popularization plans. According to the situation you know, what experiences and lessons can we learn from them? In terms of specific implementation details, how can we promote the healthy development of domestic industries?
Zhang Wenliang: Although the country has introduced LED street lighting plans, in fact, the demand is not expected to come quickly. At present, the demand for high-power LEDs comes from lamps and bulbs, and LED street lamps are not the main body. However, under the state's massive release of the standard, the market still places high expectations on LED street lights. Not only is China's LED lighting popularization plan implemented, but some national and regional governments are also actively promoting LED street lights. For example, Los Angeles also plans to set up 140,000 LED street lights within five years, and Taiwan announced that it will replace 1.28 million LED street lights within three years. Relevant institutions predict that the global LED street lamp demand will double to 2.5 million this year, with an annual growth rate of 178%.
However, it is in such a favorable environment that the domestic LED street lamp market has negative news from time to time. Under the unprecedented business opportunities of firestorms, there has been a phenomenon that manufacturers have rushed into the market. Many domestic LED street lamps are manufactured. Because of the rapid advancement of the manufacturers, the quality of the products is uneven, ignoring the technical research and development, excessive advances lead to frequent problems in practical applications, and some even return to the feathers. The reason is because there are many competitors in the LED street lamp market, and the quality of related manufacturers is uneven, which makes the products easy to fall into the price competition, thus reducing the gross profit margin of LED street lamps.
In this regard, Qinshang Optoelectronics has been planning ahead in 2007, and has focused on the research and development of independent products and technologies through cooperation with universities and colleges such as Tsinghua University. Up to now, a number of patented technology independent innovation products have been developed, which have gained more voices in patents and technology. In the current situation where the core patents are monopolized by foreign manufacturers, the core competitiveness of the company is improved and won. More cooperation and development opportunities.
Therefore, we recommend that manufacturers need to improve product differentiation competition, more to improve product quality, avoid price wars, capable companies should apply for UL and EU CE safety certification, and switch to the European and American markets to avoid falling into the price fight. This will effectively promote the development of the domestic LED industry in a healthy and good direction.
Optoelectronic News Network: How do you view the future Chinese market? What achievements have your company made in the Chinese market?
Zhang Wenliang: At the end of last year, due to the financial turmoil, the overall market sentiment of the LED industry turned from prosperity to recession. However, under the premise of limited energy and endless demand, and the launch of the national “Ten Cities and Ten Thousand Cities†plan, it was timely launched. Demand from the market, stimulated by government subsidies or incentives, more and more application fields use LEDs to replace traditional light sources. It is expected that the future development of LED in the lighting market will develop with the track of “public, private, first-class, and small, big and big,†and there is a market of nearly 100 billion yuan of LED lighting and related industries. demand.
Under such a large market background, Qinshang Optoelectronics has targeted LED street lights, LED lighting and LED decoration as the core industries of the enterprise and the main business of listed companies. The newly developed series of high-power LED street lamps all passed the strict energy-saving, safety and reliability testing and quality certification of the Electronic Fifth Research Institute of the Ministry of Information Industry. This indicates that Qinshang's product research and development has reached the level ahead of the domestic industry, and has the qualification to prioritize the government's key projects. The threshold for market access is fully open.
With the “passportâ€, we first took the lead in Dongguan and Guangdong Province, with Dongguan Dongguan as the market radiation center. From 2007 to now, Qinshang Optoelectronics cooperated with top domestic and international design elites to create a series of quality projects all over the country. And the international market, the high-power LED street lamp model project reaches 500 kilometers nationwide, and the number of installed lights is more than 30,000. Including Beijing Green Olympic Road Lighting Project, Guangdong Science Center Plaza and surrounding road lighting project, Tsinghua University Olympic venue road lighting project, Zhongshan, Dongguan and other urban areas, township streetlights comprehensive renovation project, etc., semiconductor lighting products are used throughout Guangdong, Beijing , Shanghai, Tianjin, Shandong, Jiangsu, Zhejiang, Hunan, Hubei, Guangxi, Jiangxi, Chongqing, Henan, Hainan, Liaoning, Heilongjiang and other domestic markets, as well as Asian, Australian, European, American and other international markets, Malaysia to Singapore The highway LED streetlight project agreement is about to be signed. The total length of the project is more than 1,000 kilometers, and the number of LED street lamps used exceeds 50,000.
At the same time, in the domestic market comprehensive layout, the construction of sales and after-sales service centers throughout the provinces and regions, has set up eight market radiation centers and distribution centers in Guangdong, Beijing, Shenyang, Fujian and other professional markets, and plans to be in the provinces of the country The city has opened more than 30 branches and developed more than 1,000 franchise and chain stores.
Optoelectronics News Network: We have noticed that foreign companies are more focused on the research and development of indoor lighting technology. Relatively speaking, Chinese manufacturers pay attention to the special lighting market such as LED street lights. How do you view this problem?
Zhang Wenliang: I have the following information:
1. Foreign companies. Although the LED market economy has become more conservative in 2008, the LED chip manufacturers' research and development results have been sent out with encouraging results. After Osram was released in July 2008, its current 350mA high-power LED luminous efficiency has been After successfully increasing 136lm/W, Cree announced that its high-power LED luminous efficiency has reached 161lm/W, which is currently the highest level in the industry. According to the LED luminous efficiency announced by Cree on the 19th, the high-power LED with LED size of 1mm and current of 350mA has a luminous efficiency of 161lm/W at room temperature, a brightness of 173lm and a color temperature of 46,890k. Earlier Cree announced a luminous efficiency of 129 lm/W and a brightness of 135.5 lm. Cree currently produces cold white LEDs with a maximum power of 107 lm/W and warm white light of 87 lm/W. Cree did not announce a detailed timeline for when it was possible to mass produce 161 lm/W.
Other international manufacturers are currently producing high-power LEDs with a size of 1mm and a current of 350mA. Nichia can reach 134lm/W; Lumileds is 115lm/W. The data released by Taiwan's leading manufacturer, Jingdian, is 100ml/W, which is expected to rise to 120lm/W in 2009. The current size of 20mA is 120lm/W, and next year's target is 150lm/W. With the improvement of LED technology, the luminous efficiency of LED has also reached new highs. The industry believes that if LED is to be cut into the main lighting source market of indoor lighting, the target luminous efficiency of mass production is 150lm/W. All major manufacturers are actively developing towards the goal of 150lm/W. Cree's layout in the general lighting market is quite active. In addition to the breakthrough in luminous efficiency, it is also actively working to reduce costs and increase production capacity. next year, Cree will also use wafer sizes from existing 2 inches, 3 inches and 4 inches. 6 inches propulsion.
In the indoor lighting product segment, next year Cree will also introduce colored LED lighting products that use various RGB LEDs to mix light. It is reported that in the fourth quarter of 2008, Cree's LED lighting revenue has a growth rate of 140%, and high-power LED is the strongest growth driver. Cree is quite optimistic about the general lighting market. Currently, LEDs in Europe and America have 70% of signal sign lighting. With the above market share, the flashlight is as high as 75%. In the landscape lighting market, white LEDs have also successfully cut into HID street lights.
2. Chinese manufacturers. Regardless of LED components or LED streetlight suppliers, it is widely believed that the LED streetlight market will take off quickly from 2009 to 2010. Many people believe that the LED streetlight market in 2009 was not greatly affected by the economic environment, especially under the impetus of Obama's energy conservation and China's policy of expanding domestic demand.
In many public engineering markets, LED street lights are currently the focus of development. The main reasons are: 1. The price of LED street lamps has dropped sharply, which has shortened the investment recovery period of LED street lamps. 2. Street lamps are outdoor lighting, and people can actually feel LED street lights. The effect of LED street lamp technology is relatively mature, so it has become the main promotion project for governments to promote LED lighting.
