Human beings are indeed intelligent higher creatures. From the fire of the ancient monks to the modern people, the light is no longer just the daylight of nature; from Edison's carbonized cotton filament lamps to modern 21st century LED lights, humans The lighting industry has entered a period of prosperity.
With the development of the economy and the reduction of the earth's resources, energy conservation and environmental protection have gradually become an attitude of people's lives. In a series of lighting products, the LED lighting series has become an energy-saving and environmental protection ambassador. First of all, LED power is low, power consumption is small, in line with the national policy of energy conservation and environmental protection; secondly, LED products and other products are more humane, it will not produce radiation as a light source, it will not give people a glare. The light is soft and makes people feel comfortable; in addition, the LED has great stability and will not weaken after a long time of use. It is also because LED has the advantages that other lighting products do not have, which makes the LED lighting market have great prospects and potential. Nowadays, LED lighting products are widely used in the market, home lighting, outdoor lighting, landscape lighting, stadium lighting. , Road Lighting, etc., the benefits of which are extremely attractive to many businesses.
Development status of Led Street Lamp market
LED is called the fourth generation of illumination source. Because of its energy saving, environmental protection, long life and small size, it is widely used in various lighting fields because it meets the requirements of energy saving and environmental protection. In recent years, countries around the world have launched a fierce technical competition around the research and application of LED. The United States has invested $500 million since 2000 to implement the National Semiconductor Lighting Program. The European Union also announced a similar plan in July 2000. With the support of the “863†program, China first proposed the development of semiconductor lighting plans in June 2003. iSuppli predicts that the overall LED market turnover will increase by approximately 13.7% in 2007, the compound annual growth rate in 2006-2012 will be approximately 14.6%, and will reach $12.3 billion in 2012.
Among the many LED lighting products, the market for LED street lamps is the hottest. According to the data from LEDinside Research, the number of Led Street Light devices in the world is about 610,000 in 2009. The number of LED street lights in 2010 is estimated to be about 870,000. In 2009, the number of LED street lighting installations in China was about 250,000 baht. It is estimated that by 2010, China's LED streetlight market will grow by 60% to a scale of more than 400,000 ,. The production capacity of LED street lamps by various enterprises has far exceeded the market demand. Many times. Why is the development of LED street lights so fast? Originally, compared with conventional high-pressure sodium lamp street lamps, LED street lamps can directly convert electrical energy into light energy, which has many advantages that traditional street lamps do not have. For example, the LED Street Lamp itself has directivity of light, no light diffusion, ensuring light efficiency, and the overall light efficiency is stronger than that of the high-pressure sodium lamp; secondly, the light color rendering of the LED street lamp is higher than that of the high-pressure sodium lamp; and, the LED street lamp can Automatic dimming, can meet the lighting requirements of different time periods, reduce power and save energy as much as possible; in addition, LED is a low-voltage DC device, driving the voltage of a single LED is a safe voltage, so it is a safer than using a high-voltage power supply. Power supply, especially suitable for public places; LED street light has long life, easy installation and reliable quality; the most important point is that LED light source does not contain harmful metal mercury, unlike high pressure sodium lamp or metal halide lamp when it is scrapped. The environment causes harm.
The distinctiveness of LED street lights has also been favored by the lighting market. In April 2009, the “Ten Cities and Ten Thousand Miles†project of the Ministry of Science and Technology was officially launched. It is planned to install millions of semiconductor lighting products in 21 pilot cities in three years, which opened the curtain for replacing large-scale LED street lamps in China. . According to the statistics of the High-tech LED Industry Research Center (LIRC), 222,000 LED street lights were installed nationwide in 2009. It is estimated that the installed number of LED street lights will reach 1.12 million in 2009-2011. Other cities that are still in the pilot phase of the project are expected to be rolled out from 2010 to 2011. In addition to China's vigorous promotion of LED street lights, the world's lighting industry giants - General Electric, Philips, Osram have also cooperated with semiconductor companies to set up lighting companies.
Factors limiting the development of LED street lights
The hot LED street lights have made China's LED lighting companies spring up like bamboo shoots. According to public information, there are more than 3,000 LED lighting industry-related enterprises, including more than 2,000 application companies and 600 large-scale packaging companies. There are 42 chip companies, but in general, the number is large and the scale is generally small. In the past two years, in order to further contact the LED street lamp market, many companies have begun to engage in the production and research and development of LED street lamps, but the quality is uneven. Most enterprises are limited by capital and technical level, and their products have not undergone strict light. Professional design in electricity, heat, etc., or poor understanding of road lighting quality requirements and lighting distribution, or directly copying other people's concepts, or subjective imagination, any combination, arrangement, etc., so the test and practical application effect China has brought many problems. Nowadays, the LED light source on the market generally has a problem of light decay. In some manufacturers, the LED street lamp is installed less than one year, and the brightness is seriously attenuated. When LED street lamps convert electrical energy into light energy and heat energy during operation, the reliability of the lamp will drop by 10% for every 2 °C rise in component temperature. When the operating temperature is raised from 63 °C to 74 °C, the average life of LED will be reduced by 3/. 4, chip packaging, lamp cooling and other factors may cause light attenuation. Therefore, light decay has become one of the reasons that restrict the development of LED street lamps.
In addition, domestic LED street lighting companies rely mainly on invisible channels such as engineering for market development. The explicitization of brands and channels will eventually become one of the conditions for the widespread application of semiconductor lighting products. At the same time, brand and channel construction will also determine the competitiveness of enterprises. The key to development.
At present, there are only a few enterprises that have truly made LED street lamps as their main business, strengthened investment in science and technology, formed independent intellectual property rights, and obtained patents, contributing to the development of LED street lamps. Yisongfu (Shenzhen) Electronics Co., Ltd. Vice President Zhang Shaoxiong told us: "The development of LED street lights is not very mature. Everyone is only at a stage of exploration, because the structure of LED street lights is different from traditional street lights. There are many environmental problems, and there is no unified standard. Therefore, the development of LED street lights needs to be 'cautious'."
In general, the current LED street lights, as emerging light sources, have many advantages, some products can also be applied to the actual, but there are still unstable performance, energy saving, life and theory are very different, product quality is uneven, no Uniform standards, poor interchangeability, high prices, high maintenance costs, etc. If LED street lights are to continue to develop rapidly and healthily, enterprises need to develop strengths and avoid weaknesses according to the characteristics of LED light sources and the application characteristics of road lighting products. Under the premise of satisfying lighting quality, improve product quality and life, reduce product costs, and form a standard series. To facilitate product maintenance and update. Vice President Zeng Hanming of Dongguan Tailin Coil Manufacturing Co., Ltd. also said that although the LED lighting industry is developing well, he also supports the LED lighting industry. However, he believes that the technology of LED street lamps is not yet mature, and the market development has not yet stabilized. Enterprises should not The "LED" is too "deified" and pursues short-term benefits. It should be based on the real demand point of the LED street lamp market, do a good job of technology, and set a steady start.
Future development prospects of LED street lights
Although LED street lamps still have the above-mentioned problems in all aspects, in the past few years, the country has gradually moved closer to international standards after many reforms on the development standards of LED street lamps. The system has been reformed by the state, the funds have been helped by the government, and the development of LED street lamps has become better and better. On June 24, 2010, the Guangdong Provincial Government held an on-site meeting on the application of LED streetlights in Guangzhou to summarize and promote the experience of LED streetlights in Guangzhou and other places. Zhu Xiaodan, member of the Standing Committee of the Provincial Party Committee and executive deputy governor, emphasized the application of LED streetlights. Promoting the rapid development of the LED industry is a breakthrough in cultivating strategic emerging industries, a key point for stimulating domestic demand, a breakthrough point for energy conservation and emission reduction, and a new fulcrum for improving the capacity for independent innovation, and accelerating the transformation of economic development in the province. The way to build a modern industrial system is of great significance. Taking Guangdong as an example, this year, Guangdong Province began to implement the “Ten Thousand Miles†high-power LED street lamp industrialization demonstration and promotion project, which is about 1,500 kilometers in Guangzhou, Dongguan, Foshan, Zhongshan, Zhaoqing and Shantou. LED street light demonstration and promotion project with a scale of about 100,000 baht; in addition to Guangdong Province, Wuhan City, Hubei Province, launched the largest street lighting renovation plan, plans to replace 13296 路 street lamps this year, involving 270 communities; Chengdu City, Sichuan Province, "Ten Cities" Wanhao's "Semiconductor Lighting Application Engineering Pilot Implementation Plan (2009-2011)" was officially released. Within three years, more than 10,000 LED street lights and tunnel lights were promoted and applied.
According to the 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%. With the development trend of global energy conservation and emission reduction, the demand for LED street lamps has increased rapidly. After the launch of the “Ten Cities and Ten Thousand Miles†program in China, according to the forecast of the Tuoba Industrial Research Institute, 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. The penetration rate is 8.5%. In addition, in terms of price, LED street lamps are more expensive than traditional street lamps, but after comprehensive use of electricity and maintenance costs, LED street lamps are almost equal to the total cost of high-pressure sodium lamps after two years of use. Therefore, in the long-term goal, the cost of using LED street lamps will be better than the current high-pressure sodium lamps. For example, the 8-meter LED street light is compared with the high-pressure nano lamp. The power consumption of the high-voltage nano lamp is about 250 watts, and the LED needs only 60 watts. There is also a high luminous efficiency of the LED, and the light effect of the currently available LED has reached 100lm/W, its luminous efficiency is much higher than energy-saving lamps, metal halide lamps and electrodeless lamps, which is 10% higher than the high-pressure sodium lamps commonly used in street lighting. Therefore, LED has now become one of the most luminous sources of light, and replacing LEDs such as incandescent lamps, fluorescent lamps, metal halide lamps and high-pressure sodium lamps with LEDs is only a matter of time. We believe that the market competitive advantage of LED street lamps will be verified by time. It has become a consensus for everyone to replace traditional street lamps 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 there is still a great room for its development. Minister Chen Guoping of Dongguan Dazhong Electronics Co., Ltd. also believes: "The LED street lamp market has potential for development, but it must face many tests at present, and constantly develop itself in the test, so that it will continue to mature." LED light source is energy-saving, environmentally friendly Safety, long life, rich colors, reliable performance, and so on, we can't deny the significant advantages, and the LED street lights appear under the influence of the policy is to follow the trend of development. With the rapid improvement of the light efficiency of LED light source, the technical level of LED street light distribution design is gradually matured, and the price of LED light source is reduced. LED street light has more and more advantages than traditional light source street light, so LED street light has a broad Prospects. In addition, solar cells, as a green energy source from solar energy, are characterized by simple structure and long life. They are inexhaustible energy sources. If solar cells are used as driving energy for LED light sources, a new green energy industry will be formed. The growth point will make this industry have a larger application market and development space, which will produce immeasurable social and economic benefits.
LED street lamp development has driven the development of the magnetic component market
According to Taiwan media, China's “Ten Cities and Ten Thousand Cities†plans to build 1.4 million LED street lights in 2009, of which about 50% will be supplied by Taiwan. Throughout the LED street lamp industry chain structure, both the upstream chip and the downstream packaging part have close cooperation with the downstream LED street lamp manufacturers. As for the heat dissipation module, the heat dissipation plants of different fields have entered and cooperated with the lamp factory. Goods, jointly develop and develop LED street light product specifications. In addition, the competition in the field of LED lamp assembly is also very fierce. In addition to the investment of its own LED lighting factory, the upstream component packaging factory and the heat dissipation plant are also actively entering.
According to incomplete statistics, only about 2 to 3 million street lamps are currently standing on the road in Guangdong Province. It is expected to replace 5 million LED energy-saving street lamps in the next 3-5 years. A common LED street light requires about one transformer and two inductors. Then to complete this project, it will take about 5 million transformers and 10 million inductors. China currently has 660 major cities. Although some other towns and villages cannot install LED street lights in a short period of time, we still believe that it is not impossible to install LED street lights in the next few years and decades. It is not difficult to see from this point that in the future, there will be huge room for development in the market for various inductors and electronic transformers. Yishenfu (Shenzhen) Electronics Co., Ltd. Vice President Zhang Xiongxiong also believes that if LED street lights can no longer be on paper, and really promoted from the whole country, it will bring a new development to the magnetic components market.
Preparation of magnetic component companies to enter the LED street light market
Nowadays, the era we live in is an era of information. All walks of life rely on information to understand the market, understand the opponents, and develop themselves. The magnetic components are no exception. According to China's magnetic materials industry research and consulting report, in recent years, China's magnetic materials industry has been greatly developed, with an annual growth rate of more than 20%, and the production has also begun to take shape. The middle and low-end products occupy a large international market. High-end products have also begun to form a competitive edge. According to relevant statistics, the global magnetic materials market will grow at an annual growth rate of 15%. In the next few years, China's magnetic materials industry will mainly improve in terms of quality and performance, and the growth rate will be slower in terms of output.
With the rapid development of LED street lamps, the development of the market and technology of the magnetic component industry and products has also been driven. LED street light products are developing in the direction of high performance and high quality in the future. There is no doubt that high demands are placed on magnetic material products. Therefore, LED street lamp companies in the market have also attracted consumers with different angles of innovation. "I think now, LED street light technology needs to be improved, so it is necessary to cooperate with magnetic components. Especially in controlling the magnetic sense, the magnetic impression of LED street lamps will drop. This should be noted." Chen Min, a researcher at Huizhou Chunying Semiconductor Lighting Technology Co., Ltd., said. But frankly, in fact, everyone's application of LED street light magnetic components are not far behind. From the overall point of view, electronic transformers and inductors as a basic device in LED street light products, is indispensable in the application of LED street light products. However, most of them are selected on the basis of existing products. How to improve the requirements of magnetic components to better adapt to the development of LED street lamps has become a common problem for everyone.
First of all, the development of magnetic components must be market-oriented, closely track the development trend of digital and networked technologies, and constantly develop new products to improve the quality of products. It is necessary to understand that quality is the decisive factor of a product. To adhere to a product that wins by quality, the development of vitality will be stronger. Shenzhen Mayor Guangguang Lighting Technology Co., Ltd. Zhu Xiaotian Zhu said in an interview: "There are many suppliers available on the market, but many components are still in the price increase, or out of stock, we choose to pay attention to It is not the size of the other company's size, but whether the quality and process of the material reach a level close to the international level. Quality is the primary factor we consider."
Secondly, for the mold shape of LED street lamps, the design of magnetic components should be more diversified and personalized, so that the tiny components can exert the maximum working efficiency. Mr. Fu Baocheng, project manager of Honeywell Langen Electrical System Technology (Guangdong) Co., Ltd., also has high requirements for design. During the interview, he said: "At present, the level of foreign component product design is relatively high, China is still In the stage of learning other people's concepts, how to design products with their own level is very important for future development."
Finally, in addition to focusing on product-related performance, it is also important to provide relevant product sales services, and to be stable to customers in terms of supply. Minister Yuan Yuxiang of Guangzhou Jiufo Electric Co., Ltd. said that their magnetic component product partners should do a good job of stable supply. The market is infinitely changing. In order to give customers a satisfactory impression, the partners must have Stable supply capacity.
The LED street lamp market is on the rise. Whether it is for upstream or downstream companies, there are boundless opportunities for development. However, as the saying goes, "The future is bright, the road is tortuous." If you want to enter this market, you must consider how to solve the obstacles in the development of LED street lamps and grasp the most core market information. These issues require you. Entrepreneurs have experienced and summarized in the constant market test.
