Urban lighting why attracted worldwide attention, but the level is not high"

Li Dong sequence through a lot of city at home and abroad. As the Secretary for urban construction, the Ministry of construction, he paid special attention to and often interesting analysis of the city lights. He said: "from the 1879 American scientist Edison invented the incandescent lamp, to bring the night light, the development of lighting technology has gone through 125 years, the history of the use of light in our country has a history of 122 years. Exhibition lighting hair today, has not only a simple to satisfy the human basic needs, as to improve people's lives and promote economic and social development of culture material, is a symbol of city civilization and modernization. However, the level of urban lighting in China still can not keep up with the needs of urban development, compared with developed countries, the overall level is not high."

Chinese urban lighting "attracts worldwide attention"

At the end of November 2004, Chinese held the International Symposium on city lighting. A Chinese scholar who went to Europe 20 years ago to attend the meeting. He still remember 20 years ago when he was in the night after flying over Europe, the plane is a light in the ocean; and until the last century at the end of 80s, when the scholar to fly back to Beijing, the night of the China only a few big city lights to shadowy into plane people's field of vision. But in other areas it is almost dark.

The International Symposium on Chinese city lighting, city construction in the face of domestic and foreign experts, Li Dong order proudly presents the situation of China's city lighting today to the end of 2003, the National Street development to more than 8 million 730 thousand, is 7 times that of 1999. The street has constantly updated technology, from the use of incandescent lamp, fluorescent lamp, to use high pressure sodium lamp, metal halide lamp, road lighting conditions greatly improved, the steel pole replaced wooden and concrete poles, lamp light distribution is more abundant, more reasonable; control of street lighting by manual operation, time control and light control technology development to the centralized remote monitoring, started using advanced digital communication technology management. The overall level of city landscape lighting has also been greatly improved, from the simple pursuit of light up to the pursuit of beauty, from the simple pursuit of quantity to the pursuit of quality, from scattered construction to have the overall layout planning, from the general to the light source into the high-tech means, lighting practices are becoming increasingly diversified, optical fiber, light emitting diode LED use a large amount of gold, ceramic lamp CDM, CNC electronic dimming and other advanced technology to make our country more and more bright sky city, more and more beautiful.

Indeed, today's Chinese city lighting not only makes the European scholars gankaiwanduan, but also left a deep impression to the international friends. Before the European Lighting Designers Association President Francesco, Sweden, mayor of Jessore, Ling cable, Italy Si Kay to the board of directors of the company leader of Changbai Adidas and other international city construction problems in city lighting experts have Chinese International Symposium on multiple sincerely commended China City Lighting "rapid development", "large scale" and "world".

Urban lighting from the perspective of science, culture and art

Tan Qinglian, chairman of China Civil Engineering Society, is an expert on urban lighting. He has a specialized interpretation of urban lighting urban lighting is the city's functional lighting, including roads, bridges, tunnels, public square lighting and urban night landscape lighting, which is the main element of urban landscape lighting. Urban lighting is a new comprehensive subject, including culture, art, architecture, environment, psychology and engineering technology. Its role has 31 with brilliant color change will set off in the night in the city landscape, city night chelseagreat; two is to make the city image of remodeling and reconstruction in the night, to create a safe environment bright and pleasant and delightful night view of the city, to create a specific cultural atmosphere of the city, a heritage and the connotation of city culture; three is the embodiment of city construction and management level of achievement.

It is out of the role of the city lighting above three considerations, Li Dong has been in a variety of occasions on China's urban lighting problems. These issues are classified into 5 aspects he some city streets and residential lighting facilities is not complete; the city lighting rate is relatively low, the uneven lighting level of primary and secondary roads; some city focus too much on the lamp shape, don't pay much attention to the lighting effect; some city landscape lighting is too bright, spoil the balance, causing glare or light pollution, waste of energy; our country city lighting problems of cultural taste is not high, the construction management is not standardized.

The above problem is of course the Li Dong order according to today's level of understanding of China's city construction science -- today's city construction has the City Lighting Science understood as a science and a culture and an art". From this point of view, compared with the developed countries, China's overall level of urban lighting is not high." Li Dong such a generalization.

Improving the urban lighting with the guidance of Scientific Outlook on Development

November 23, 2004, the Ministry of construction and the national development and Reform Commission issued a "strengthening the management of urban lighting to promote the work of saving electricity. This document is not high in our country city lighting level expression is lagging behind the regulations and relevant standards, the construction market confusion, pay attention to engineering construction, despise maintenance management; ignored lighting design cultural taste and harmony with the environment, the pursuit of pure brightness, the pursuit of luxury, caused by light pollution; the use of inefficient lighting equipment, a serious waste of energy city, intensified electricity shortage. Experts point out that this "formal" expression includes not only the
