Looking at the future trend of urban lighting

The night of the bright lights of Expo Park in Shanghai, located in the city best practice area on the east side of Puxi Park under the lights become magnificent.

From the French city of Lyon, the tulip bulbs are slim, well-proportioned; projection lamp to whirling and other insects, partly hidden and partly visible wall; creative light show by aliens visit earth lead the tulip petals of the plot, let people taste a sound color ".

Shanghai, World Expo is the theme of "Better City, better life", while the lights at night is an integral part of urban life. In a sense, provides an ideal model of the Expo Park city best practice area lighting case for the future development of city lighting, so these cases reflects the future trend of the development of what kind of city lighting? Days ago, Xinhua News Agency reporters interviewed on the issue of foreign lighting planning and design experts, ask them to this interpretation.

Pay attention to lighting planning

Public area lighting Shanghai World Expo city best practice area 80% and the pavilion of all cases are building lighting designed by the French Rhone Alpes region.

One of the highlights of Luo ah region is the World Expo city lights case best practice area. In this case Jin Liang said the person in charge of this case, the biggest innovation is the lighting planning and design, "big area in the city of Lyon from about 20 years ago began lighting planning, but in China this is a relatively new concept". He believes that in the future urban lighting system construction, we must introduce the steps of lighting planning.

In the practice of city area lighting as an example, the first designers of regional brightness and color temperature were defined, and then find out the "Night Garden" the art line, whether it is plants, petals, fireflies and other other lights are for art line services.

Cobalt company is one of the two is responsible for the lighting design of the French company, its leader Pierre - Philip Gardner said, hope that their design let people walk in the practice area, "returned to the village, in the field in this light, flooding the city is particularly valuable".

Musashino Art University Professor Kaoru Mende told reporters that the lighting planning should consider and city style. "Lighting planning should be a unique product of light culture and modern technology into local history, topography, climate and climate on the basis of the combination, should be in the premise of better use of local customs and culture, showing a unique historical and cultural city, the mode of life, aesthetic consciousness and social economic environment. "

Chicago famous architectural design and urban planner Wo John Nalan Cic believes that the reasonable planning and careful design of urban lighting is the key to the magical charm of the city night. From an aesthetic point of view, every night in the city is a secret, the secret lies in the careful planning of lighting, the city's structure and the city's main water body and the relationship between the buildings. When these distinctive urban elements are illuminated by the lights at night, it will turn the city we know in the daytime into a place of great charm".

Application of energy saving technology

With the emergence of global energy crisis and global warming, "green lighting" has become an important concept of lighting design. Kaoru Mende professor pointed out: "green lighting is simply to reduce the unnecessary use of lighting lamps in use, as far as possible to choose the high energy efficiency, long service life, low carbon dioxide emissions products, can also consider the future of wind and solar and other clean energy applied to city lighting, green, low-carbon and sustainable the city lighting target. "

The best practice area of the city is led by light emitting diode lamp and solar lamp. Jin Liang said that compared with the traditional light source, they can significantly reduce energy consumption, reduce carbon dioxide emissions, the future may be widely used in urban lighting. But he also stressed that at this stage the two there are still some limitations in use, such as the brightness of the light emitting diode lamp less than traditional light source, can not be used in the requirements of high brightness areas; solar lights need to install solar panels, will affect the appearance of lamps. He believes that the traditional light source through a number of design and technical improvements and a lot of energy saving space.

In this regard, a British expert at the University College London, vice president of the British Association of lighting Peter Renam agrees, he said, most of the current British city lighting system are used in the traditional light source, such as most street lights using the xenon lamp, the technology to improve the traditional light source also has higher energy efficiency.

In addition, experts believe that to reduce energy consumption, to achieve green lighting, not only to rely on energy-saving lamps, but also for the unified control and management of lighting systems. Jin Liang believes that the future of urban lighting will tend to focus on management, and more use of weak technology to control the lighting. Pierre - Philip Gardner believes that the management of city lighting, lighting brightness adjustment should be based on different time.

Avoid light pollution

In the past, the city lighting, especially the large and medium-sized cities, pay more attention to the lighting equipment with the help of the night city to create a bright day approaching effect. Experts believe that this approach not only makes the city's night scene stereotyped, but also led to serious light pollution, damage to the health of residents.

Urban best practice area lighting design plan to take into account to avoid the problem of light pollution. "All lights in the practice area
