The "Water Cube" of the Olympic project that has been lit up has made LED (Light Emitting Diode) into the eyes of the general public. LED products are energy-saving, environmentally friendly, and have a long life. Previously, outdoor landscape lighting in major cities in China was also using LED products. In addition to the lighting projects and landscaping of the city and tourist areas, many communities and major construction projects, as well as restaurants and hotels, are now adopting LEDs to replace traditional and power-consuming neon lights. China's LED landscape lighting can be described everywhere. According to relevant statistics, in 2007 China's LED outdoor landscape lighting output value reached 6 billion yuan, indoor landscape lighting is about 1 billion yuan. LEDs have begun to form emerging industries, and experts suggest that special attention should be paid to the requirements of art, humanity and intelligence in the development process.
Beautify the environment due to the "view"
At present, landscape lighting accounts for the largest share of LED application market in China, accounting for 25%. Landscape lighting is growing rapidly under the impetus of the government. It is mainly based on decorative lighting in public places such as streets and squares, which can save 70% of electricity. Common landscape lamps include: garden lights, trail lights, buried lights, small spotlights, lawn lights, fast lane lane lights, wall lights, sculpture decoration, etc. Influenced by the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo, Beijing, Shanghai and other venues have accelerated the pace of landscape lighting. It is estimated that the average annual compound growth rate of landscape lighting sales will reach 37.2% in the next three years.
The goal of LED landscape lighting is to coordinate the landscape lighting with the landscape. Because of the “viewâ€, it is suitable for the characteristics of the building and achieve a new level of landscaping. Li Jinxi, director of the Institute of Semiconductors of the Chinese Academy of Sciences, said that the design of LED lamps should be beautified during the day and the art under night. "LED light source is easy to realize automatic change control, colorful. At present, the three primary color LEDs are controlled by 8-bit digital gray scale, and the color types can reach 16.77 million kinds, which can play a role in the landscape and make it more artistic. In addition, LED as a landscape lighting also has the advantages of high reliability, easy non-standard design and ultra-long span control," said Li Jinxi.
Fang Zhilie, a professor at Fudan University, believes that LED technology has gradually matured in landscape lighting, regional standards have been formulated, the industry is being regulated, and its advantages of energy saving, environmental protection and beautification are being fully utilized. The reliability of luminaires in landscape lighting is still a problem worthy of attention. Heat dissipation and waterproof technology are key issues and should be given special attention.
The application of landscape lighting is the base of LED applications. At present, it is also the area where LED applications maintain the longest stable growth cycle. Chen Hesheng, deputy general manager of Jiangsu Wenrun Photoelectric Co., Ltd., believes that its advantages in landscape lighting are unparalleled, soft light, bright colors, easy to achieve dynamic digital control, good application prospects, but also for the whole society in the energy shortage In the background, further improving the level of urban beautification and lighting provides a highly feasible solution.
With the acceleration of the urbanization process, all local governments have increased the implementation of urban landscape lighting. Because of the energy-saving, safe and colorful characteristics of semiconductor lighting, the current points and lines in the landscape lighting are bright. The chemical industry has already demonstrated obvious market advantages and has become the absolute main force in the market. The comprehensive competitive advantages in replacing traditional blistering and neon lights have become quite obvious. The urban landscape lighting market will usher in an explosive growth period. Liang Bingwen, general manager of Shanghai Lanbao Optoelectronic Materials Co., Ltd. believes that due to the low power consumption of LEDs, it has strong competitiveness in the landscape lighting market with huge power consumption. "In 2006, the domestic LED lighting market grew at a rate of more than 70%. Its market size is about 20 billion yuan per year. The future development of the market is to improve the design level of landscape lighting, jumping out of simple hooks and running. The cookie cutter can combine the advantages of LED to provide high-quality, high-grade lighting engineering and products." Liang Bingwen said.
