City night view lighting light environment in existing problems and development trend

The current urban construction has become the mainstream of social life and construction career development. The quality of the people in the pursuit of living environment. Light environment is also an important for the people to pursue the high quality of the environment, lighting engineering and lighting technology is a major means of creating light environment, the current is changing and developing rapidly. Many years ago, people night out, as long as there is light, road and now road not only bright, the road building is also very bright. Early years is big cities 'lighting', development to the medium-sized city, now there are many small towns began to show their own economic strength, at the money and energy, in order to attract tourists, tourism environment. Cities in more than 20 years 'lighting' project development to the present is called 'lighting'. Regardless of the actual situation, he is brighter than you, I am brighter than he. To form a light environment deterioration, resulting in 'light pollution'. Light pollution of the environment noise, the environment is dirty air, damage people's health, causing people's psychological be agitated, or even walk away from the light, or rather to the darkness, the heart is rather quiet place. And outdoor lighting of high power high intensity light source directly affect the indoor rest and sleep, despite the increase of heavy curtain, although can temporarily block glare and not completely block out heat. And carelessly, strong light drilling into the interior. What instead of the lighting engineering and technology. The significance of current city 'brighten' should be changed to 'beautify'. 'Beautify' is to make the environment elegant, comfortable, environmental protection, health, and energy saving. Energy saving is the big issue, the nation was in energy saving, cities, all walks of life, men and women, old and young, everyone is concerned about energy conservation. For saving energy and saving resources, is to protect the environment, the benefit of future generations, and the sustainable development of the century ten thousand generation. Create light environment of the work must also be energy-efficient lighting engineering and lighting technology, also will be able to energy saving. The waste of energy and harmful environmental engineering should be under control. Those who create beautiful energy-saving light environment engineering should be encouraged and developed. Energy saving and environmental protection is a national policy for the sustainable development of our country construction enterprise, China lighting electricity accounts for about 12-14% of all electricity. And night view engineering all over the country, according to statistics, the electric consumption is equivalent to the engineering of indoor lighting electricity 5 ~ 10%, and the trend of rising. This is a huge amount of electricity, not to be sneezed at. The future development trend of urban nightscape lighting project should be in addition to energy saving, also should pay attention to light environment elegant, color and movement. A, 1, energy saving from the following several aspects to choose high luminous efficiency of the light source 2, 3, choose reasonable choose the lamps and lanterns of high efficiency lighting 4, and the choice of energy-saving lighting 5, choose the reasonable power supply circuit and control method of 6, select the appropriate control time and period 7, strictly comply with the requirements of the CIE standard lighting and brightness level 8, with lighting energy saving of new products and high-tech products, LED decorative lighting will save you a lot of energy. 9, strengthen the maintenance and management of night view lighting is an important part of energy saving. 2, elegant environment, light environment is not only popular 'lighting' in a 'light' than work. Large area flood lighting is too much, will form a large area of high brightness, cause glare. And the structure of the local lamplight ornament and lighting highlight visual effect will be more comfortable and elegant, will get twice the result with half the effort. Can use small power light source and lamps and lanterns is no or little use of high power, can use the line light source appears less building outline is suffused with large area light and strong light. Three, the color is simple but elegant is likely to be more like the colorful colorful, will cause the messy. Especially in a long, wide, multistory buildings designers seems to want to make a red, orange, yellow, green, blue, purple, however, because the light is cross each other, and not flatly separate, so the result is bad. Many years ago there was a big city near the train station is in a large building with high-power project-light lamp, lighting from down to up, use a variety of color light source, green, purple and yellow form all kinds of ribbon, effect is very poor, make people disgusted. Color choices it is best to focus on atmosphere and emotional appeal. And according to the structure of the use and characteristics, such as government office buildings, government agencies, Banks, customs and other places, to serious not to too many colors. Four, indoor don't blink too dazzling to attract tourists, business, entertainment and tourist attractions can use dynamic changes in the light. But enough is enough, do not use 10 ~ 15 times per second light flashing, easy to make people visual fatigue. Grave sites without best described earlier, such as simple with only the outer contour lines. Move too much will also form the visual discomfort, make people disgusted. Shenzhen lighting academy at the end of each year to name a few outstanding energy-saving lighting engineering, several good enterprise and the member unit has a good engineering works. Some buildings such as flood lighting in the past is always in a, two hundred kva electricity. Using new light source equipment in more than 50 kva electricity can, effect, was satisfied people passing by. In 2005, 2 (3) of the economist and volume 2, 2005 mid-term 4 visible to the images of these projects.
