Dai Deci: China's Lighting Energy Is Vast City
In recent years, China's urban construction boom lighting
, especially during major holidays and important celebrations, the city has become a landscape lighting, display of city scenes to promote the city's external relations, tourism, market economy, and many other aspects of urban construction development. However, there are still many areas ground vigorously in this city, "lighting" project, the blind pursuit of brightness, lighting up the city's night sky, but also a waste of valuable resources. Now, with energy saving ideas to take root, people gradually realized that the city is not the more light the better, lighting should be reasonable, comfortable, and on this basis to achieve energy conservation.
Recently, I interviewed the Chief Engineer, Electrical Design Institute of Tsinghua University, Beijing Institute for Environment and chairman of Dai Deci, she told the author that the city is much room for energy-saving lighting, as long as the Key links, it is possible to ensure illumination and lighting in effect under the premise of the road to achieve energy-saving lighting and landscape lighting.
Development and implementation of lighting standards
Outdoor lighting street lighting and landscape lighting is divided into two parts, China has successively promulgated the "city road lighting design standards" and "Urban Landscape Lighting Design" in the detail of these standards provides illumination of the target . In 2006, Beijing established the "City Landscape Lighting Technology Standards" can be said to be a more comprehensive local standards of urban lighting has an important role in guiding the scientific development. It is understood that the local standard of Beijing "City the first part of energy saving lighting equipment: Outdoor Spot Lighting Energy-saving requirements, "has passed inspection, the standard for the first time gives Floodlights limited value of energy efficiency and energy conservation evaluation values, to fill the energy requirements of urban lighting equipment blank, the promotion of energy-saving products on the application of lighting will play an active role.
Dai Deci told the author that, although the city launched the standard lighting, but the application of these standards is still a subject of urban lighting construction. Road lighting, my existing two extreme situations: some less developed urban road illumination lighting may not reach the national standard, affecting the normal traffic safety; while some developed areas of public lighting is far more than the standard provisions, some of the city road lighting is too bright, a waste of energy, does not meet energy requirements, which require governments at all levels strictly in accordance with the norms and standards for road lighting construction.
In landscape lighting field, due to poor implementation of standards, some areas of China still engage in "urban lighting." Many cities in landscape lighting, light scattering, interference of light in serious condition, night Searchlight , Narrow-beam cast light in all directions according to the city, the sky has not see the moon and the stars. Landscape lighting is neither over-building energy-saving, but also damage the environment, causing light pollution and affect the health of residents. Therefore, the urgent need to strengthen enforcement of standards for landscape lighting.
Minutes time, intelligent control sub-sections Beijing during the Olympic Games, the Olympic main stadium lights surrounding areas, which show the hospitality of the Chinese people, heighten the festive atmosphere of the Olympic Games, plus time traffic, human traffic greatly improve the favorable safety lighting standards. However, after the Olympics, drivers and pedestrians and then went to these places will feel that way too bright a light! This, Dai Deci that after the Olympics, the lighting can be adjusted as appropriate brightness of the requirements specification can be . By extension, road lighting can be used in different sections of different illumination, main roads, secondary roads, residential area roads were degree requirements are different lighting levels can be determined separately, using different power lamps, rational design height and distance between light poles in order to maximize energy efficiency.
