LED Road Lighting Development Calls for New Game Rules

In the past 2010, China's LED lighting industry has achieved unprecedented development - from breakthroughs in the research and development of high-power LED chip technology to one billion LED chips to light up the practical application of the Shanghai World Expo, from capital enthusiasm to policy to force; The prosperity of the industry is delightful. However, with the advancing of time, lighting products that have already been put into use have continuously exposed some problems, so we have to clearly understand that as an emerging technology and application, LED lighting is in some areas, especially in the field of road lighting. There are still some problems that will restrict future development.

As a more environmentally friendly, reliable and healthy energy-saving lighting method, LED street lamps are unanimously recognized as the leading part of the next-generation road lighting field. Since the beginning of 2009, the Chinese government has increased the support and promotion of LED road lighting, and implemented pilot projects in 21 more economically developed cities. As of the end of 2010, a total of more than 350,000 LED street lamps were newly installed nationwide. However, LED lights installed throughout the country have not been used for a long time. Many problems have arisen in terms of product quality and lighting effects. They have focused on road lighting that is not bright enough, glare is dazzling and glare, and products have been exposed to serious light for some time. Bad or not at all. The emergence of so many problems in a very short period of time has to some extent constrained the further expansion of product applications. At the same time, it also allows the industry to calmly think about how the future of the LED streetlamp industry will develop.

In response to the problems that have arisen, some industry experts pointed directly at the crux of the problem. “On the one hand, we are eager for quick development and many technologies are not mature enough. Many new players entering this field do not have enough R&D students and Production capacity; but more importantly, a considerable number of practitioners still have a lot of misunderstandings about what constitutes an energy-saving streetlight. They are simply pursuing a reduction in the unit's energy consumption and ignoring respect for the product's application environment.

What is the standard LED street lamp that is energy-saving? In view of the status quo of China's LED street lamps industry, Philips took the lead in proposing to measure the lighting effects and energy-saving effects of LED street lighting products by meeting the road lighting application standard's power density (LPD); the system light efficiency can only be one of the product evaluation indicators, but not comprehensive. Measure the advantages and disadvantages of lighting effects and energy-saving effects. The correct evaluation criteria are primarily to meet the road lighting design standards, and energy conservation is also bound to meet this standard as a prerequisite, taking into account people's visual needs. “Excellent lighting products are often the result of the combination of leading technology ideas, craftsmanship, and user experience. The company has always advocated a people-centered approach to ensure that products can truly meet the needs of users.” In this concept and leading global LED With the support of technology, Philips has launched a series of LED road lighting products in recent years. Taking Philips' latest Green Vision LED series as an example, this product has an achievable luminous power density value LPD (W/m2) as a measure, with four system lighting effects and an optical system designed specifically for China's road conditions. With enough brightness and illumination to ensure road safety, people can bring comfortable and safe lighting experience with appropriate color temperature, so that energy-saving effect and user evaluation can be optimized.

China is the world’s largest energy consumer and is also the most energy-efficient market. At present, China has more than 17 million street lights, and the market potential of future LED road lighting is very large. However, the development of LED road lighting in front of each practitioner is not a smooth path. There are still many problems in the future and we need to work together to resolve it. 2011 is the first year of China's "Twelfth Five-Year Plan". In the "Twelfth Five-Year Plan", the state will accelerate the development of LED lighting standards as the top priority of industrial development. Under the premise of building a resource-conserving and environment-friendly society, the establishment of a scientific and fair game rule that is in line with international standards will be the key to China’s success in the LED lighting industry. It requires the wisdom of every practitioner and decision maker. And contribution.
