The meaning of the current city “lighting†should be changed to “beautificationâ€. “Beautification†is to make the environment elegant, comfortable, environmentally friendly, healthy, and energy efficient.
Energy conservation is a major issue at present, and energy conservation is carried out in all countries. All cities, all walks of life, men, women and children, everyone cares about energy conservation. Because it saves energy and saves resources, it is a great cause that protects the environment, benefits future generations, and is sustainable. Lighting engineering and lighting technology that create a light environment must also be energy efficient and energy efficient. Engineering that wastes energy and is harmful to the environment should be controlled. Those who create beautiful energy-saving light environment projects should be encouraged and promoted.
Energy conservation and environmental protection are the national policies for the sustainable development of China's construction industry. China's lighting electricity accounts for about 12-14% of all electricity use. According to statistics, the night-time project in all parts of the country consumes 5 to 10% of the electricity used for indoor lighting in the project, and there is still an upward trend. This is a huge amount of electricity, and this number cannot be underestimated. In the future, the development trend of urban night lighting projects should be in addition to energy conservation, but also pay attention to the elegance, color and movement of the light environment.
First, energy conservation should start from the following aspects
1. Select a light source with high luminous efficiency
2, choose high efficiency lamps
3. Choose a reasonable lighting method
4, choose energy-saving lighting appliances
5. Choose a reasonable power supply line and control method
6, choose the appropriate control time and time period
7. Strictly comply with the lighting standard values ​​and brightness levels specified by CIE
8, the use of lighting energy-saving new products and high-tech products, LED decorative lighting will save a lot of energy.
9. Strengthening the maintenance and management of night lighting is also an important part of energy saving.
Second, the environment is elegant and popular
The light environment is not the "bright" work in "lighting". If there is too much floodlighting in a large area, it will form a large area with high brightness and cause glare. The local lighting accents and lighting highlights of the building may make the visual effects more comfortable and elegant, and will do more with less. The use of low-power light sources and luminaires eliminates the need for high-power, and the use of line sources to represent building contours eliminates the need for large areas of floodlights and glare.
Third, the color is simple and elegant, it may be more like
The green, green and colorful flowers will cause chaos. Especially on a long and wide multi-storey building, the designer seems to want to make a red orange, yellow, green, blue, and purple. However, because the light is crossed and not separated, the effect is even worse. Many years ago, a building near a railway station in a big city used high-powered floodlights to illuminate from bottom to top, using a variety of colored light sources, with green, purple and yellow to form various ribbons. Poor, making people resentful. Color selection is best focused on the atmosphere and mood. And according to the use and characteristics of the building, such as government office buildings, institutions, banks, customs and other places, it is necessary to be too solemn.
Fourth, the movement is appropriate, don’t be dazzled
Business, entertainment and tourist attractions can be used to attract tourists, and you can use dynamic changes. However, it is necessary to stop, do not use 10 to 15 times per second of glare flashing, easy to make people visual fatigue. The above-mentioned solemn place is best not used, and if it is used, it can only be a simple change of the outline of the outer contour. Too much motion can also create visual discomfort and disgust.
Each year, the Shenzhen Lighting Society has selected several excellent energy-saving lighting projects at the end of the year. Several better companies and member units have better engineering works. In some buildings, if floodlighting is used, one or two hundred kilovolt-amperes of electricity will always be used. With the new light source and new equipment, only more than 50 kVA of electrical energy can be used, and the effect is good. The pedestrians are also very satisfied. Color drawings of these projects can be found in Volume 2, No. 3, 2005, and Volume 2, Number 4, 2005.
All electro-acoustic parameters have reached the leading level of similar products, and are widely used in special products police Dept. Fire Dept. Ambulance and fixed places for alarm matching use so on ! it can match with with our all siren products to work !
Problems and development trends of light environment in urban night lighting project
The current urban construction has become the mainstream of social life and construction. People are pursuing the quality of the living environment. The light environment is also an important aspect of the high-quality environment that people pursue. Lighting engineering and lighting technology are the main means of creating a light environment, and the current is changing rapidly. Many years ago, when people went out at night, as long as the road was bright, now not only the road is bright, but the buildings on the roadside are also bright. In the early years, the big cities were “lighting†and developed into medium-sized cities. Now many small towns have begun to show their economic strength, and they are willing to spend money and energy in order to attract tourists and create a tourism environment. The development of the city's “lighting†project in the past two decades has now become “lightingâ€. Regardless of the actual situation, he is brighter than you, I am brighter than him. Thereby, the light environment is deteriorated, resulting in "light pollution." Light pollution is equivalent to environmental noise. The environment is like dirty air, which damages people's health, causes people's psychological irritability, and even walks away from the light, or prefers to go to the secluded place of darkness and heart. While the high-power and high-intensity light source of outdoor lighting directly affects the rest and sleep in the room, although the heavy curtains are added, although the glare can be temporarily blocked, the heat cannot be completely blocked. Moreover, if you are not careful, the glare will get into the room again. What are the reasons for these lighting projects and technologies.
