The rapid development of urban landscape lighting is not only beautiful but also energy saving

In recent years, the rapid development of urban construction in China, the construction of landscape lighting has also been the relevant government departments attach great importance to all cities are doing "bright" work. However, in the rapid development of urban landscape lighting, we also have some lighting design of the "excessive lighting" has been questioned, in particular, but also pay attention to the importance of aesthetic energy saving.

Rapid development of landscape lighting

The so-called landscape lighting refers to both lighting, outdoor lighting facilities has art to decorate and beautify the environment function in China. In the past people's material life level is not high, public welfare is not developed, so the landscape lighting is not popularization and development. In recent years, China's rapid economic development, urban construction with each passing day, the construction of urban landscape lighting is also accelerating.

Urban landscape lighting by. The input of landscape lighting in the search engine, I saw dozens of city landscape lighting construction on domestic news reports, such as: Shantou city landscape lighting center automation, Wuxi 54 landscape lighting facilities renovation of a new Jiangsu, Wuxi central business district landscape lighting design "switch", Tianjin start LED lamps landscape lighting project Shanghai, Waibaidu Bridge, Chongqing urban landscape lighting provoke new ideas of night landscape lighting planning introduced in June...... The construction of urban landscape lighting has been greatly improved.

Light pollution: artificial daylight

Light pollution problem was first proposed in 1930s by the international astronomical community, they believe that light pollution is the city's outdoor lighting to the sky caused by the negative impact of astronomical observations. International light pollution is generally divided into 3 categories, namely, white pollution, artificial daylight and color light pollution. In this paper, we refer to the problem of light pollution in the light of "artificial daylight".

Artificial day refers to the night after the advent of shopping malls, hotels, advertising lights, neon lights flashing dazzling. Some of the strong beam even straight into the sky, making the night as day, in such a "night city", the night is difficult to sleep, disturb the normal human body clock, resulting in low efficiency during the day.

In the process of the development of urban landscape lighting, many cities blindly pay attention to the lighting project, highlighting the brilliant light and color, a waste of electricity, resulting in serious light pollution. At present, the large cities, the use of light, so that the sky is too bright, can not see the stars, the impact of astronomical observation, aviation, etc., many astronomical observatory was forced to stop working. According to astronomy statistics, the sky at night without light pollution, you can see the stars is about 7000, while in the city, street lamp, landscape lamp to the background, can only see about 20~30 stars.

Urban lighting is not only important to better energy conservation

Shanghai Waibaidu Bridge is not only beautiful landscape lighting more energy-efficient [Shanghai Waibaidu Bridge Landscape lighting using LED light source to replace the original metal halide lamp, all kinds of lamps add up to 2000, was only 490, but the energy consumption is from the original 73 kilowatts to about 42 kilowatts, decreased more than 30%. ]

It is necessary to develop the urban night landscape, to beautify the modern city, to cultivate the city's public sentiment, to improve the quality of life, to show the characteristics of the city, to promote the prosperity of the business and tourism, etc.. But we should also see that some places simply pursue brightness, or even excessive pursuit of luxury, has caused a serious waste of electricity, and even bring the city's light pollution.

In today's increasingly tense energy crisis, energy saving and emission reduction is the general direction, so our city in the development of lighting construction, we must also save energy in the first place. Now the city for lighting energy saving methods are the following:

1, to carry out the existing energy-saving lighting engineering transformation, after the completion of the transformation, its power consumption dropped significantly;

2, actively promote the "green lighting", a large number of LED (light-emitting diode) lighting products to replace the traditional, power hungry neon lights;

3, the government appropriate intervention, make the landscape lighting time limit, in order to effectively save energy.

The experts also called on the government to the lighting industry, for landscape lighting generally exceed the standard problem of building landscape lighting to eliminate the competition psychological, to carry out examination and approval before construction, there are specific penalties for need to exceed the standard. We hope that the city's night scene in the light at the same time, can not only beautiful and more energy saving.
