Making Full Use Of The Advantages Of Urban Characteristics And Exploring The Rational Direction Of Urban Lighting

- Mar 13, 2019-

In today's view, it may be precisely because Zhengzhou City Lighting started early, in recent years, when major cities have made efforts, Zhengzhou is still not moved, the development of urban lighting is slow, or based on the previous work to do some repair. Perhaps it is also because of the self-confidence of construction and the surge of the tide that Zhengzhou has more calm thinking time. It needs to wait and accumulate, and explore a better lighting way that conforms to the orientation of urban characteristics.

For the problems of urban lighting in Zhengzhou, from the summary of the data, it can be roughly summarized as the following aspects:

Lack of professional design and outdated design techniques

The existing lighting in Zhengzhou lacks professional design, obsolete design methods, single content and backward lighting technology. Some lamps and lanterns irradiate inappropriately, lack of illumination, color imbalance and architectural style are inconsistent.

Lack of reasonable planning and sufficient scientific basis results in light pollution and waste of resources

Due to the lack of reasonable planning and sufficient scientific basis, some lighting projects unilaterally pursue the brilliant and colorful lighting effects, which disturb the people and affect the ecological environment, resulting in huge waste of social resources and serious light pollution to the environment.

Lack of characteristics

Most buildings do not pay attention to architectural lighting, because of the single lighting method, only using a large area of floodlight illumination and lack of multi-level local lighting, lack of creativity and expression, making the day's distinctive buildings appear pale and tasteless at night.

Lack of scale and integrity

Lack of sense of scale is mainly reflected in the performance of hard landscape at night. The common problem is that the macro is superfluous and the details are insufficient. Many small-scale facilities for pedestrians during the day become roadblocks at night, and lamps lack careful consideration in both shape and scale. In fact, all kinds of lamps and lanterns in urban space are the link between daytime and night landscape: daytime can embellish spatial features; nighttime is the "second eye" of human beings, which can give full play to its guiding and guiding role, and its own shape is also an active factor of night symbols of urban scale and characteristics. At the same time, many units pay attention to highlighting their own image at night, but lack the overall concept, which leads to the building lighting at night is self-governed, disorderly, without focus, lack of integrity.

These problems in Zhengzhou, more or less, are also the problems that most cities in China are facing in lighting. For the solution of these problems, some experts have put forward the following suggestions for improvement:

Making Full Use of the Advantages and Characteristic Resources of Cities

There are many open urban parks, green spaces and squares in Zhengzhou. There are Guangda Square, Bauhingshan Park, People's Park and Bishagang Park along Jinshui Road to Jianjian Road, and Greentown Square, Zhongyuan Park, Zhengxing Park and Erqi Square along Zhongyuan Road to East-West Street. In view of this characteristic, the planning and design should be based on the people-oriented design concept, and focus on lighting design of these urban public activity space to form a good landscape, as a supplement to Street building lighting.

At the same time, Zhengzhou has abundant cultural and historical resources and some buildings with good shape and large volume. Zhengzhou in the center of the city has a revolutionary historical significance of the 27 Pagoda, the famous Henan Museum. Lighting design should embody the cultural and historical characteristics of Zhengzhou, and actively display Zhengzhou's cultural characteristics in the whole city's night scene lighting. Through the design, light can convey cultural information, create night scenery reflecting Zhengzhou's historical characteristics, and form an important element of night vision and the city's landmark night scene.

According to the way that the urban spatial structure and landscape scale influence the view, the section characteristics and rhythm control of lighting along the road can be considered. The continuous street interface night scene and outstanding key landscape make visitors form a complete and distinct intention to Zhengzhou night scene in the process of viewing.

Creating Characteristic Urban Nightscape Lighting by Controlling Colors

Color has an important impact on people's vision and psychology. We must control the use of color in urban night lighting. According to the characteristics of each region of the city, the use of color is determined, and through a comprehensive investigation of the current night scene, the use of color is adapted to the original city night scene, highlighting the characteristics. Note that the use of color light and lighting is closely related, can not be misused, such as edge with white and blue, floodlight with warm white and yellow. In some places, such as building contours and signs, large areas of flooding with color light are still dominated by white and yellow. Local areas can use more color changes to create a warm and rich atmosphere.

Strengthen the Nightscape Characteristic of the City by Lighting Way and Flexible Use of Dynamic Lighting

It can use the combination of outline, floodlight and penetration to highlight the characteristics of lighting objects. The lighting mode should be planned as a whole, and the lighting of the same section should be enriched on the basis of unification. For example, a section of the road may use the top edge, forming a unified overall effect, individual buildings combined with floodlight or sign lighting show rich effect. Dynamic lighting can be used in commercial areas and public leisure areas to create a rich and lively atmosphere. Business District billboards are unified planning and design to avoid chaotic state.

According to the characteristics and conditions of Zhengzhou City, the implementation of night lighting is carried out by stages.

The planning and design of night scene lighting should be based on the characteristics and current situation of Zhengzhou city, and put forward the steps of phased implementation, so as to make the lighting planning more feasible. For the key nodes which have great influence on the overall night scene effect or play a key role in drawing the finishing point, the lighting should be implemented first to make the city have a more complete night scene, and then gradually carry out the lighting of the rest of the city. For the lighting of buildings, it should be graded according to the type of buildings and the environment, and then proceeded step by step: first, the lighting of the surrounding nodes and important buildings, then the lighting of the other important buildings on the road section, and finally the lighting of general buildings to form a complete urban night scene.

From this, we can see that there are many improvements in the urban lighting environment of Zhengzhou, and Zhengzhou itself is actively exploring, waiting for the arrival of a new look. On this occasion, the Aladdin Shendeng Award Organizing Committee, together with local societies, street lighting institutes, engineering companies and other units, visited and inspected the night scenery of Zhengzhou on the spot, and discussed the lighting of Zhengzhou in the form of a symposium.

At the symposium, Feng Jian, deputy secretary-general of Henan Illumination Society, introduced the situation of urban lighting in Zhengzhou. He said that urban lighting in Zhengzhou developed around 2002. After the development period, there were no major events and no key changes. Now the recommended place is the central commercial area of Jinshui District, in which "corn cob" (Millennium Square building shape resembles corn cob, so it has this name locally) is a part of comfort. Compared with other cities, it is not so gorgeous, colorful, soft color, which makes people feel comfortable, and it has become a landmark building of Zhengzhou.

In the view of Chen Shaohua, the designer of Henan Pan-Light Lighting Engineering Co., Ltd., Zhengzhou is bright in the East and dark in the west, which has obvious regional space distinction. The Eastern District represents the direction of the new urban planning and development. The planning and design of night scenery lighting is ahead of the others. It has relatively good forward-looking planning. The lighting environment is better than that of the western district. It connects the whole eastern district with the "corn stick" as the core visual point. The buildings of Ruyi Lake form a group light with complete volume. Except for the eastern CBD area, there is a good lighting effect, other areas are relatively inadequate. On the whole, he thinks that the lighting of Zhengzhou city may lag behind that of other cities such as Beishengguangshen for three or five years, and the most impressive thing for outsiders is "corn cob". But Zhengzhou is the birthplace of multi-culture. Before "corn cob", the 27th Memorial Tower is the earliest landmark of Zhengzhou city, and it is a memory node of the times and even culture. It has a good carrier, a good story and a good calendar. History precipitates, but at present the publicity efforts and the cultural atmosphere of lighting excavation are not prominent enough. "Do not blindly follow, do quality fine lighting; slow down the pace, let the road of lighting develop naturally; take culture as the point of view, make night lighting works with the characteristics of the Central Plains; in the multimedia era, highlight its own connotation, so that the lights deeper." This is Chen Shaohua's suggestion for Zhengzhou lighting.

Liu Boxue, the principal designer of Zhengzhou Dongzhichen Lighting Design Co., Ltd., expressed his views from a more macro perspective.

Based on the volume of night scenery in Zhengzhou, he believes that Zhengzhou has not yet established a preliminary system of night scenery. The roads, boundaries and signs of the city are very important basic works, while the night scenery in Zhengzhou is still in a confused state. The color of lights and the outline of buildings can not well represent the city. If we can let people into the space, feel the light well, let people have a new understanding of lighting, lead people's aesthetic, make more quality and meaningful lighting, this is what he expected.

Li Xubo, deputy director of Lighting Institute of Henan Urban and Rural Planning and Design Research Institute Limited, also shared his views:

He believes that the whole lighting in Zhengzhou now belongs to the characteristics of the Central Plains, which is relatively backward compared with some cities at the same level in China. Its development may depend more on some policy trends of Zhengzhou. "Zhengzhou has witnessed rapid economic development in recent years. The whole urban area has been expanding and the infrastructure has been improving. For lighting, Zhengzhou wants to do better on the shoulders of giants. In 2018, the relevant departments also put forward the design and planning intention of lighting plate, which may be five years late, but when it is really made, it will make people see clearly."

From this point of view, Feng Jian mentioned that they participated in the research and development of night scene lighting in various cities and found that the relevant government departments in various regions were also confused by the lack of clear acceptance criteria for infrastructure construction such as road lighting. Understanding these conditions, Henan Lighting Society also planned to join Henan Housing and Urban and Rural Construction Department and Zhengzhou Municipal Engineering Survey and Design Institute with the help of science. LED inspection center, drafting relevant acceptance standards and local road standards, and setting up a platform to organize short-term service classes with street lamp departments to help improve skills and aesthetic ability, guide planning rationally; and put forward suggestions on how to adopt more scientific and reasonable ways of management and maintenance in the later stage, in view of the comparatively emerging energy management, PPP mode advantages and disadvantages. Analysis, so that the relevant personnel have a more comprehensive understanding.

For the delightful urban lighting of Zhengzhou, it is obviously necessary to gather the wisdom of designers, experts and the government to show the charm of the city, so as to avoid entering the ranks of uniform and homogeneous cities.

As a lighting designer, Zhang Ruiming, the design director of Henan Xinzhongfei Lighting Electronics Co., Ltd., expressed his design attitude.

He believes that the designer must stand in the position of Party A to locate the plan, tailor the clothing to make a satisfactory plan for the owners, all demand-oriented, quality-assured. In his view, the designers in Zhengzhou have the vision and depth of designers going north, and the government supports the development of local engineering companies. The value of designers is also waiting for good projects to reflect.

As an industry expert, Wang Jiyun, chairman of Henan Illumination Society, spared no effort to travel all over the country to attend the conference to understand the development of lighting in the country. From his point of view, Zhengzhou City Lighting is now in the underdeveloped third world, but the lighting work of Zhengzhou Municipal Government Department is in place, and the society and relevant government units are actively cooperating in training urban lighting construction managers in 18 cities and nearly 100 counties in the whole province to help establish a cross-regional "Urban Wisdom and Big Data Alliance" to promote intelligent street lamps. He holds technical consultation and technical appraisal of major construction projects in Henan Province (including the construction of four centers, wisdom island, ecological environment construction of 100 km long Jialu River, opening ceremony of the third Henan Games, etc.).

On the basis of establishing such a benign relationship, the development of Zhengzhou is imperative. Relevant leaders of Zhengzhou Municipal Engineering Survey and Design Research Institute also disclosed that after the urban construction of Zhengzhou tends to be perfect, the government will accelerate the design and planning of the lighting sector, and large construction projects are just waiting for the time to mature.
