The application of LEDs in the field of outdoor lighting is a technology that has emerged and developed rapidly in recent years. China is a fast-growing country, and the demand for urban outdoor lighting is growing. Therefore, how to reduce energy consumption and use energy-saving systems has become a major hot issue that the Chinese government attaches to and considers. The high efficiency, energy saving and low pollution characteristics of LED lighting systems have become a good way to save energy and reduce emissions worldwide. At present, LED outdoor lighting is not only used in alley lights and square lights, but also the main areas of road lighting and landscape lighting.
According to relevant statistics, there are currently more than 2,000 enterprises producing outdoor lighting products in the country, mainly in Zhongshan Guzhen, Zhejiang Liangnong, Suhu and other places. The lighting of public areas in the city has also begun to demonstrate application. It has also made some progress in the alley lights and square lights. The landscape lighting has developed rapidly in the past two years. The future landscape lighting will be the generation of LED dances. Vigorously promote and global industrial ladder transfer, the future of China's LED outdoor lighting will become the most attractive cake on the market. So what is the development trend of the LED outdoor lighting market in 2009? Let's analyze it together.
From the perspective of landscape lighting, go hand in hand with road lighting
“Landscape lighting†gives the city a beautiful beauty. In the modern urban people's fashion concept, it is not only limited to the light of the city's night sky, but more attention is given to its proper light intensity and well-constructed natural environment space. The enjoyment of beauty brought about by people - oneness and one restraint, one reveals one hidden, reflects the change of fashion and the modern rhythm, and increases the spatial change, while expressing the inner culture of the city in another form. It is the ultimate goal of modern landscape lighting. LED is favored by landscape lighting for its huge energy-saving effect, lightweight structure, compact size and pure and rich color of light source. Its evolution can be any color, better than the color metal halide lamp, the decoration is unparalleled. It is precisely because LED lights meet the decorative aesthetics of landscape lighting. In the past two years, LED has entered the outdoor landscape lighting market with its unique advantages and occupied 43% of the LED outdoor lighting market, becoming a unique show for LED outdoor lighting applications.
On April 28, 2009, the Ministry of Science and Technology officially issued Document No. 189, agreeing to carry out pilot work on semiconductor lighting application engineering (referred to as “Ten Cities and Ten Thousand Milesâ€) in 21 cities including Shanghai, Chengdu and Tianjin. As early as December 2008, the large-scale replacement of LED streetlights and LED streetlights in China's Guangdong Province was also implemented. In two years, it will achieve 1500 in 10 cities including Dongguan, Foshan, Huizhou, Zhaoqing and Zhongshan. Replacement of 100,000 ç› LED street lights. At present, there are at least 130,000 LED streetlights in the 21 cities in the country, and the number of LED street lamps is increasing. The wide application of LED road lighting has announced to the world that LED outdoor lighting has gone from landscape lighting to road lighting, and has been moving toward large-scale use.
Policy to promote the scale application of LED street lights
In March 2009, the Ministry of Science and Technology held a symposium on “Implementing the “Ten Cities and Ten Thousands†LED Lighting Application Demonstration City Program in Beijingâ€. The meeting decided to increase the “Ten Cities and Ten Thousand Miles†pilot demonstration work and expand the scope of the pilot. For the problem of increasing the cost of using LED street lamps, the Ministry of Science and Technology will carry out the economic and social benefits of LED products according to the economic and social benefits obtained by LED lighting, according to the investment increase of 30%-50% compared with traditional lighting. subsidy. Since then, LED street lights have become the focus of local governments, and local governments are actively taking measures to promote LED street lighting applications. The strong support of the state and local governments has become the main driving force for the growth and scale application of the LED street lamp market in China. Under the situation that the country vigorously promotes LED street lamps, enterprises should seize this development opportunity, continuously improve the heat dissipation performance and power quality of products, and strive to reduce costs, so that the LED street lamp market can continue to maintain rapid growth.
At present, LED lighting technology is becoming more and more mature. According to the data, the light efficiency of high-power LED light source has reached 80lm/W, which makes energy-saving renovation of urban street lighting possible. In 2009, the total market of street lamps in China reached 28 million baht, and the number of new and replacement street lamps increased from 3 million to 4 million baht per year. According to relevant predictions, LED street lights increased by 178% in 2009 compared with 2008. It is expected that LED street light applications will reach more than 8 million in 2011.
Although China's LED road lighting has made considerable progress, there are still some problems that need to be solved urgently. For example, LED street lamps have poor heat dissipation capability, short service life, and poor power quality. The unclear standards also affect the market to some extent. development of. In addition, inferior products have a negative impact on market promotion. Sub-charged LED products seriously disrupt market order, causing people to distrust the reliability of LED street lamps. This is also a common concern in the industry; in terms of cost, high-power LED street lamps The initial purchase cost is relatively high, about 2 times to 3 times that of traditional street lamps, which puts pressure on the market application of LED road lighting products.
LED landscape lighting and LED street lights are still hot spots
In terms of market applications, LED landscape lighting and LED street lights will remain the focus of the LED outdoor lighting market in 2010. At present, the penetration rate of LED landscape lighting products is gradually increasing. LED street lights have achieved certain development under the support of the government. However, due to the limitations of LED street lights, such as heat dissipation and light extraction efficiency, the market development is still in its infancy. In addition, LED alley lights and square lights have gradually become a hot spot for market attention. LED lights have been widely used in current alleyways and square lighting, and the application in square lights will gradually increase.
LED is widely used in landscape lighting. With the advancement of society and economic development, human beings are constantly pursuing the quality of life, and landscape lighting has an inestimable space for development. The successful use of LED in the Olympic venue "Water Cube" indicates that the technology of LED lighting in landscape lighting has gradually matured. At present, regional standards for LED landscape lighting have been formulated, and the industry is being regulated. Its advantages of energy saving, environmental protection and beautifying life are being fully exerted. The use of LED lighting instead of traditional neon lights can save 60% to 70% of electrical energy. With the acceleration of the urbanization process, local governments have increased the implementation of urban landscape lighting. China's large and medium-sized cities, lighting projects and landscaping lighting in tourist areas are gradually arranging LED landscape lights. Many communities and major construction projects are using LEDs to replace traditional and power-consuming neon lights. China's LED landscape lighting is welcoming new developments. peak. At present, according to conservative estimates, only the domestic landscape lighting market is more than 20 billion yuan. Conventional landscape lights such as garden lights, walkway lights, lawn lights, wall lights, building outline lights, small spotlights, road lane lights, and ground LED lights can be used for buried lights, underwater lights, etc. Although the current landscape lighting source is mainly fluorescent energy-saving lamps, incandescent lamps, halogen lamps and neon lights, LED light sources have entered the landscape lighting market with their unique advantages, becoming a unique show of landscape lighting. We have reason to believe that with the technological advancement of the LED industry, the scale of applications continues to expand, and the cost is further reduced, LED light sources will become the main source of landscape lighting.
Under the trend of active energy conservation and emission reduction in the world, the demand for LED street lamps is also increasing rapidly. The survey data of the Industrial Research Institute in Taiwan shows that the penetration rate of global LED street lamps in 2007 was only 0.23%, but the penetration of LED street lamps in 2009 The rate is over 1% and can reach 4% in 2011. According to the plan of the Ministry of Science and Technology of China, the Ten Cities and Ten Thousand Planners entered the second phase in 2010, from the current 21 semiconductor lighting demonstration cities to 50 cities to build 2 million LED street lights. Officials estimate that the penetration rate of LED lighting will reach 30% in 2013. Based on this estimation, the annual market size of lighting street lamps in the country should be no less than 5 billion yuan. Compared with traditional lighting systems, LED outdoor lighting systems involve complex work in many different fields, and the current price is higher than traditional street lamps, but with the advancement of technology and the rapid growth of market demand, the price of LED outdoor lighting systems will Will drop soon. Therefore, in the long-term energy-saving benefits, the advantages of LED outdoor lighting systems will not be replaced.
However, LED outdoor lighting is also facing many problems: First, the LED enterprise's mentality is impetuous, not more specialized; secondly, the product problem, the LED is more "supreme", need to support the excellent heat dissipation, constant current drive and other solutions support, improper use It is easy to appear light decay or even "dead light" phenomenon; again technical problem, LED color rendering index is low, the color displayed under LED illumination is not true of incandescent lamp and so on.
Of course, the soft ribs and short plates of these LEDs are just a small stumbling block in the outdoor lighting market, and they can't stop the LEDs from being smashed in the outdoor lighting market.
In short, in 2010, China's LED outdoor lighting industry is facing unprecedented policy opportunities, unexpected technological upgrade space, huge market potential, and broad development prospects!
