Road lighting is closely related to people's production and life. With the acceleration of urbanization in China, green, high-efficiency and long-life LED street lights have gradually entered people's field of vision. At present, LED lighting technology is becoming more and more mature, and the efficacy of high-power LED light source has reached 80lm/W, and energy-saving renovation of urban street lighting has become possible.
In terms of the market for high-power LED products based on street lamps, some LED companies have successfully developed LED street lamp products in the second half of 2005, and gradually introduced them to the market to replace the traditional street lamp products. China is currently one of the countries with the fastest urbanization in the world. It is expected that in the next few decades, the market demand for high-power, high-brightness and energy-saving LED street lighting products will be extremely large. According to the statistics of the national street lamp industry in 2006, there are more than 15 million street lamps in urban road lighting in China, and the growth rate in recent years is over 20%. According to this estimation, the annual market size of lighting street lamps in the country is not less than 5 billion yuan. If LED street lamps are used, the annual electricity saving will be more than 2 billion degrees.
In recent years, the National Semiconductor Lighting Engineering R&D and Industry Alliance has done a lot of research work on LED urban road lighting to understand the new achievements of industry technology development and the new development trend of the market. In 2005, the Alliance recommended solar LED street lights to the owners of the Beijing Olympic venues, and more than 100 solar LED street lights were displayed at the Olympic Village. A few days ago, the Alliance participated in the “2007 China Road Lighting Forum†in Suzhou. The forum was based on the theme of “Energy Application Technology for Road Lightingâ€. More than 200 representatives of domestic road construction units and experts and experts in road lighting attended the conference. LED light source was used in road lighting. The application in this topic has become a hot topic in this conference. In view of the current situation that LED street lamp standards cannot be quickly introduced, the Alliance is preparing to establish a technical specification working group, preparing to select LED street lights as an entry point, and researching and formulating technical specifications for corresponding test methods.
Although China's LED road lighting has made considerable progress, there are still some problems to be solved. For example, the lack of standard for LED road lighting products, the illumination standard of high-pressure sodium lamps with different color rendering indexes is not suitable for LED light sources; the inferior products have a negative impact on marketing, and the sub-charged LED products seriously disrupt the market, causing the competent authorities to LED The reliability of the company is skeptical; the initial purchase cost of high-power LED street lamps is relatively high, about 2-3 times that of traditional street lamps, which puts pressure on the market application of LED road lighting products.
Based on the market prospects of LED road lighting and the imperfect industrial status, the alliance will hold a forum on the theme of "2007 New Light Source & New Energy - Solar Semiconductor Lighting" in Yangzhou on May 16. This forum will further explore the development status of solar semiconductor lighting, the application of key technologies and engineering exchanges. Focus on how to improve the performance of LED and solar cells, reduce costs, optimize the design of solar LED lighting systems; how to standardize and develop new products such as solar LED street lamps in the domestic market; how to guide solar semiconductor lighting in municipal engineering, landscape lighting Reasonable application; how to seize the major opportunities for investment in emerging industries and international industrial transfer; and the construction of industrial environments such as policies and standards. The conference invited R&D, manufacturing and design personnel related to solar energy and LED, related research and testing institutions, enterprises and urban planning and municipal engineering units, investment and financing institutions, bidding units and other participants. The forum has been given more attention and expectation due to its extensive communication topics, diversified communication platforms and potentially huge business opportunities.
