Humans are indeed clever higher creatures. From the archaeologists' drill fires to modern people inventing electric lights, light is no longer just a daylight of nature; from Edison's carbonized cotton filament lamp to modern 21st century LED lighting, humans The lighting industry has entered a flourishing era.
With the economic development, the reduction of the earth's resources, energy saving and environmental protection has gradually become an attitude of people's lives, and in a series of lighting products, LED lighting series has become an energy saving and environmental protection ambassador. First of all, LED power is low, power consumption is low, in line with the national policy of energy conservation and environmental protection; Second, LED products and other products are more humane, it will not produce radiation as a light source, will not give people dazzling feeling, The light is soft and makes people feel comfortable; in addition, the LED has strong stability, and the light emitting effect will not be weakened after a long time use. Because LED has the advantages that other lighting products do not have, the LED lighting market has great prospects and potential. Nowadays, LED lighting products have a very wide range of applications, such as home lighting, outdoor lighting, landscape lighting, and stadium lighting. , road lighting, etc., where the benefits for many businesses, have a great temptation.
LED Street Lighting Market Development
LED is known as the fourth generation of lighting source, because it has the characteristics of energy saving, environmental protection, long life, small size, etc., in line with the requirements of energy saving and environmental protection, it is widely used in various lighting areas. In recent years, various countries around the world have launched a fierce technological competition around the research and application of LEDs. The United States has invested 500 million U.S. dollars to implement the "National Semiconductor Lighting Plan" since 2000, and the European Union announced in July 2000 that similar plans should be launched. With the support of the “863†plan, China first proposed the development of semiconductor lighting plans in June 2003. iSuppli Corporation predicts that in 2007 the overall LED market turnover will grow by approximately 13.7%, the compound annual growth rate for 2006-2012 is approximately 14.6%, and by 2012 it will reach US$ 12.3 billion.
Among the many LED lighting products, LED street lamps are the hottest market. According to data from the LEDinside Research Department, the number of global LED street lighting devices in 2009 was about 610,000, and the estimated number of LED street lamps in 2010 was about 870,000. In 2009, the number of LED street light installations in China was about 250,000 baht, and it is estimated that by 2010, China's LED street light market will increase by 60% to a scale of over 400,000 baht. The production capacity of LED street lamps provided by various companies has far exceeded market demand. Many times. Why is the development of LED street lamps so fast? Originally, compared with conventional high-pressure sodium lamps, LED street lamps can directly convert electric energy into light energy, which has many advantages that traditional street lamps do not have. For example, the LED street light itself has light directivity, no light diffusion, to ensure light efficiency, and the overall light efficiency is stronger than the high-pressure sodium lamp; secondly, the light color of the LED street lamp is higher than that of the high pressure sodium lamp; and, the LED street lamp can be Automatic dimming can meet lighting requirements at different times, reduce power as much as possible, and save energy. Furthermore, LEDs are low-voltage DC devices that drive the voltage of a single LED as a safe voltage, so it is a safer than using a high-voltage power supply. Power supply, especially suitable for public places; In addition, LED lamps have long life, easy installation, and reliable quality; the most important point is that LED light sources do not contain harmful metal mercury, unlike high-pressure sodium lamps or metal halide lamps when they are scrapped. Environmental hazards.
The uniqueness of LED street lamps has therefore won the favor of the lighting market. In April 2009, the Ministry of Science and Technology officially launched the “Ten Thousand Cities†project. It plans to install millions of semiconductor lighting products in 21 pilot cities in three years, opening a prelude to the large-scale adoption of LED street lamps in place of traditional lighting. . According to the statistics of the Senior Industry LED Industry Research Center (LIRC), in 2009, 222,000 LED street lamps were installed nationwide. It is expected that the installed LED street lamps will reach 1.12 million baht in 2009-2011. Other cities still in the pilot stage of the project are expected to be rolled out in large scale from 2010 to 2011. In addition to China's vigorous promotion of LED street lamps, the world's lighting industry giants - General Electric, Philips, and Osram have also cooperated with semiconductor companies to establish lighting companies.
Factors that restrict the development of LED street lamps
The heat of LED street lamps has caused China's LED lighting companies to spring up. Public information shows that there are more than 3,000 LED lighting industry-related companies, of which more than 2,000 are applied and about 600 are packaged companies. There are 42 chip companies, but overall, the number is large and the scale is generally not large. In the past two years, in order to be able to further contact the LED street lamp market, many companies began to engage in the production and research and development of LED street lamps, but the quality is uneven, most companies are limited by the capital and technical level, and their products have not passed strict light, The professional design of electricity, heat, etc., or lack of understanding of road lighting quality requirements and fixture luminaires, or direct plagiarism of other people's concepts, or subjective imagination arbitrary combination, arrangement, etc., so in the test and the actual application of the effect Both have brought many problems. The LED light source on the market currently suffers from the problem of light failure. Some manufacturers have installed the LED street light in less than a year and the brightness is seriously attenuated. When the LED street light converts electrical energy into light energy and thermal energy at work, the reliability of the luminaire will decrease by 10% for every 2°C rise in the element temperature. When the operating temperature rises from 63°C to 74°C, the average life span of the LED will decrease by 3/. 4, the chip package, lamp heat dissipation and other factors may cause light attenuation. Therefore, light failure has become one of the reasons restricting the development of LED street lamps.
In addition, domestic LED street lighting companies mainly rely on invisible channels such as engineering to develop the market. The dominance of brands and channels will eventually become one of the conditions for the widespread application of semiconductor lighting products. At the same time, the brand and channel construction will also become the decisive factor for the competitiveness of enterprises. The key to development.
At present, it is truly the LED street lamp as its main business operation, strengthening scientific and technological investment, forming independent intellectual property rights, and obtaining patents. Only a few companies have contributed to the development of LED street lamps. Yi Shen-fu (Shenzhen) Electronics Co., Ltd. Zhang Yuxiong, deputy general told us: "The development of LED street lamps is not very mature, everyone is just in a phase of exploration, because the structure of LED street lamps is different from the traditional street lamps, to be considered There are many challenges to the environment, and there is not yet a unified standard, so the development of LED street lights needs to be 'careful'."
In general, LED street lamps at this stage have many advantages as emerging light sources, and some products can already be applied to the actual situation. However, there are still unstable performances, energy saving, longevity and theoretical differences, and the quality of products varies greatly. Uniform standards, poor interchangeability, high prices, high maintenance costs and so on. If LED street lamps need sustained, rapid and healthy development, enterprises must also take advantage of the features of LED light sources and the characteristics of road lighting products to avoid weaknesses. In the premise of satisfying the quality of lighting, improve the quality and life of products, reduce product costs, and form a standard series. To facilitate product maintenance updates. Vice President of Dongguan Tailin Coil Manufacturing Co., Ltd. Zeng Hanming also said that although the development of LED lighting industry is good, he is also very supportive of the LED lighting industry, but he believes that the technology of LED street lamps is not yet mature and the market development has not yet reached a firm footing. Enterprises should not To "LED" too "godified" and chase short-term interests, should be based on the real needs of the LED street lighting market, do a good job of technology, and start calmly.
Future prospects for LED street lamps
Although LED street lamps still have the problems mentioned above in various aspects, in recent years, the country has gradually moved closer to international standards after many reforms of LED street lamp development standards. The system has been reformed by the state and funds have been helped by the government. The development of LED street lamps is getting better and better. On June 24, 2010, the Guangdong provincial government held an LED lighting application conference in Guangzhou, summarizing and promoting the application of LED street lamps in Guangzhou and other places. Zhu Xiaodan, standing member of the provincial party committee and executive vice governor emphasized the application of LED street lamps. The promotion of LED industry to promote the rapid development of the LED industry is a breakthrough in the cultivation of strategic emerging industries, a focal point to stimulate domestic demand, an entry point for energy-saving emission reduction, a new fulcrum to improve the ability of independent innovation, to accelerate the transformation of the province's economic development Ways to build a modern industrial system are of great significance. Take Guangdong as an example. This year, Guangdong Province began to implement a large-scale demonstration project to promote the industrialization of high-power LED street lamps. The total mileage is 1,500 kilometers in Guangzhou, Dongguan, Foshan, Zhongshan, Zhaoqing and Shantou. About 100,000 LED street lamps demonstration and promotion project; In addition to Guangdong Province, Wuhan City, Hubei Province launched the largest street lamp renovation plan, and plans to replace 13,296 street lamps this year, involving 270 communities; Chengdu City, Sichuan Province, “Ten City Wan Hao's "Semiconductor Lighting Application Engineering Pilot Implementation Plan (2009-2011)" was formally released. Within three years, more than 10,000 LED street lamps and tunnel lights were promoted and applied.
According to statistics of the national street lamp industry in 2006, there are about 15 million street lamps in urban lighting in China, and with the development of national infrastructure, the growth rate of street lamps in recent years is about 20% or more. With the development trend of active energy saving and emission reduction in the world, the demand for LED street lamps has increased rapidly. After China launched the “Ten Cities, Ten Thousand Cities†program, according to the Takubo Industrial Research Institute, LED street lamps in 2009 will increase by 178% over 2008, with an output value of 1.625 billion U.S. dollars. It is expected that the number of LED street lamps in the country is expected to reach more than 8 million in 2011. , Permeability 8.5%. In addition, in the price, LED street lamp prices are higher than traditional street lamps, but the overall power consumption and maintenance costs and other factors, after two years of use, LED street lamps and high pressure sodium lamps almost equal to the total cost. Therefore, with long-term goals, the cost of using LED street lamps will be better than the current high-pressure sodium lamps. For example, compared with an 8-meter LED street lamp and a high-pressure nano lamp, the power consumption of the high-pressure nano lamp is about 250 watts, and the LED only needs 60 watts; there is also a high luminous efficiency of the LED, and the luminous efficiency of the currently available LED has reached. 100lm/W, its light efficiency is much higher than that of energy-saving lamps, metal halide lamps and electrodeless lamps, which is 10% higher than the commonly used high-pressure sodium lamps in street lighting. Therefore, LED has become one of the light sources with the highest luminous efficiency. LED replacement of incandescent, fluorescent, metal halide, and high pressure sodium lamps is just a matter of time. We believe that the market competitive advantage of LED street lamps will be verified by time, and replacing traditional street lamps has become a consensus of everyone in the future.
The development path of LED street lamps is tortuous, but the situation is gratifying and the prospects are optimistic. We believe that its development still has a great deal of room. Dongguan Dazhong Electronics Co., Ltd. Minister Chen Guoping also believes: "LED street lamp market has the potential for development, but only at present must face many tests, continue to develop in the test of self, so as to continue to mature." LED light source has energy saving, environmental protection , safety, long life, rich colors, reliable performance, etc. We can not deny the significant advantages, and LED street lamps under the influence of the policy is to follow the trend of development. With the rapid increase of the LED light source luminous efficiency, LED lighting light distribution design technology level gradually mature, LED light source prices are reduced, LED street lamps have more and more advantages than traditional light sources, so LED street lamps have a wide range of Prospects. In addition, as a green energy source derived from solar energy, solar cells have characteristics such as simple structure and long life span. They are inexhaustible sources of energy. If solar cells are used as driving sources of LED light sources, a new green energy industry will be formed. The growth point will make this industry have a greater application market and development space, and it will produce incalculable social and economic benefits.
The development of LED street lamps has driven the development of the magnetic components market
According to Taiwan’s media, China’s “Ten Thousand Cities†plan to build 1.4 million LED street lamps in 2009, of which about 50% of the components will be supplied by Taiwan. Looking at the LED street light industry chain structure, whether it is the upstream chip or the downstream packaging part, it has close cooperation with the downstream LED street lamp lighting manufacturers. As for the heat dissipation module, there are different areas of the heat dissipation plant to enter, and cooperate with the lighting factory. Goods, jointly develop and formulate LED street lamp product specifications. In addition, the LED lighting assembly field is also very fierce competition, in addition to their own LED lighting plant investment, the upstream component packaging plant and the cooling plant is also actively involved.
According to incomplete statistics, only the street lights currently standing on the road in Guangdong Province are about 2 to 3 million, and it is expected that 5 million LED energy-saving street lamps will be replaced in the next 3-5 years. A common LED street light requires about 1 transformer and 2 inductors. To complete this project, it will take about 5 million transformers and 10 million inductors. While China currently has 660 major cities, although other cities, towns, and villages cannot install LED street lights in the short term, we still believe that it is not impossible to install LED street lights in the coming years or decades. It is not difficult to see from this point that in the future, there will be huge room for development in the market of various inductors and electronic transformers. Yi Shen-fu (Shenzhen) Electronics Co., Ltd. Zhang Haoxiong, vice president also believes that if the LED lights can no longer be on paper, really spread from the country, it will give the magnetic components market a new development.
Magnetic component companies to enter the LED street lamp market
Now we live in this era is an era of information, all walks of life rely on information to understand the market, understand their opponents, self-development, magnetic components is no exception. According to the research report of China's magnetic materials industry, in recent years, China's magnetic material industry has achieved great development with an annual growth rate of more than 20%, and its output has begun to take shape. The middle and low-end products occupy a relatively large international market. High-end products also began to become competitive. According to relevant statistics, the global magnetic material market will develop at an annual growth rate of 15%. In the next few years, China's magnetic material industry will mainly improve its quality and performance, and its growth rate will be slower.
With the rapid development of LED street lamps, the development of the market and technology of the magnetic components industry and products has also been stimulated. The future of LED street lighting products is developing towards high performance and high quality. There is no doubt that high demands are placed on magnetic material products. Therefore, LED street lighting companies in the market are also attracting consumers with innovations from different angles. "I think now, LED street lamps need to be improved technically. Then we must cooperate well with magnetic components. Especially in controlling magnetic induction, the magnetic sense of LED street lamps will drop. This should be noted." Chen Min, a researcher at Huizhou City Yingying Semiconductor Lighting Technology Co., Ltd., said. But frankly speaking, in fact, everyone's application of LED street lights magnetic components are not far off, from an overall point of view, electronic transformers and inductors as a basic device in LED street lighting products, LED lamps in the application of the product is indispensable However, most of them are selected on the basis of existing products. How magnetic components can improve their own requirements to better adapt to the development of LED street lamps has become a common issue for everyone.
First of all, the development of magnetic components must be market-oriented, closely follow the development trend of digital and network technology, and constantly develop new products to improve product quality. It must be understood that quality is the decisive factor of a product. Adhering to a product that wins with quality leads to a stronger development of vitality. Shenzhen Xiaoguang Semiconductor Lighting Technology Co., Ltd. Zhu Xiaotian Zhu also said in an interview: “Although there are a large number of suppliers available on the market at present, many components are still increasing prices, or are out of stock, we have chosen to focus on It's not the size of the other company's size, but whether the quality and craftsmanship of the material have reached a level close to the international level. Quality is the primary factor we consider."
Secondly, for the molding of LED street lamps, the design of magnetic components should be more diversified and personalized, so that the tiny components can achieve maximum working efficiency. Mr. Fu Baocheng, project manager of Honeywell Longneng Electrical System Technology (Guangdong) Co., Ltd., has relatively high requirements for design. During the interview process, he said: “At present, the level of design of foreign components and products is relatively high, and China is still relatively high. At a stage of learning from Others, how to design a product with its own level is very important for future development."
Finally, in addition to focusing on product-related performance, it is also important to provide related product sales services, and customers should have stability in terms of supply. Yuan Yuxiang, Minister of Guangzhou Jiufo Electric Co., Ltd. stated that their partners in magnetic components should be stably supplied. The market is constantly changing. In order to give the customer a satisfactory impression, the partners should generally have Stable supply capacity.
The resurgent LED street light market, whether it is for upstream companies or downstream companies, contains unlimited opportunities for development. However, as the saying goes, “the future is bright and the road is tortuous.†To enter this market, it is necessary to consider how to solve the obstacles in the development of LED street lamps, and grasp the core market data. These issues require everyone. Entrepreneurs experienced and summarized in the constant market trials.
