Make full use of the advantages of urban character

Make full use of the advantages of urban characteristics to explore the rational direction of urban lighting

today, it may be because Zhengzhou urban lighting started early. In recent years, when major cities have made efforts one after another, Zhengzhou is still unmoved, the development process of urban lighting is slow, and some patchwork is done on the basis of the past. Perhaps it is also because of the confidence of construction and the surging trend that Zhengzhou has more calm thinking time. It needs to wait and accumulate, and explore better lighting methods that meet the positioning of urban characteristics

from the summarized data, the problems existing in Zhengzhou urban lighting can be summarized as follows:

lack of professional design, outdated design methods

the existing lighting in Zhengzhou is lack of professional design, outdated design methods, single content, backward lighting technology, and some lamps have improper irradiation parts, insufficient illumination, light color imbalance and architectural style

lack of reasonable planning and sufficient scientific basis causes light pollution and waste of resources

due to the lack of reasonable planning and sufficient scientific basis, some lighting projects unilaterally pursue the colorful lighting effect, and there are problems such as disturbing residents and affecting the ecological environment, resulting in a huge waste of social resources and serious light pollution to the environment

lack of characteristics

the outstanding performance is that most buildings do not pay attention to architectural lighting. Due to the single lighting method, only large-area floodlighting is used, and multi-level local lighting is lacking, lacking creativity and expressiveness, making the distinctive buildings in the daytime look pale and tasteless at night

lack of sense 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 there is more macro and less detail. Many small-scale facilities set up 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 decorate spatial features; Night is the "second eye" of human beings, which can give full play to its indicating and guiding role, and its own shape is also an active factor that marks the scale and characteristics of the city at night. At the same time, many units pay attention to highlighting their own image at night, but lack the overall concept, which leads to the fragmentation, disorder, lack of focus and lack of integrity of the nighttime lighting of buildings

these problems in Zhengzhou, An expert from building materials said more or less: "Inorganic thermal insulation materials are the problems faced by most urban lighting in China, and for the solution to these problems, some experts have put forward suggestions for improvement in the following aspects:

make full use of the advantages and characteristic resources of the city

there are many open urban parks and squares in Zhengzhou urban area, and there are Everbright square, Zijingshan Park, people's Park, bishagang Park and Central Plains along Jinshui road to Jianshe Road From the road to Dongxi street, there are urban public activity spaces such as Greentown square, Zhongda garden, Zhengxing garden, Erqi square, etc. In view of this feature, the planning and design should be based on the people-oriented design concept, and focus on the lighting design of these urban public activity spaces to form a good landscape as a supplement to the street building lighting

at the same time, Zhengzhou has rich cultural and historical resources and some buildings with good shape and large volume. In the center of Zhengzhou, there is the Erqi tower of revolutionary history and the famous Henan Museum. The lighting design should reflect the cultural and historical characteristics of Zhengzhou, and actively express the cultural characteristics of Zhengzhou in the night lighting of the whole city. Through the design, the light can convey the cultural information, create the night scenery that reflects the historical characteristics of Zhengzhou, and form the important elements of night vision and the symbolic night scenery of the city

according to the way in which the urban spatial structure and landscape scale affect the viewing, the section characteristics and rhythm control of lighting along the road section can be considered. There are both continuous night scenes at the street interface and prominent key landscapes, which enable tourists to form a complete and distinct intention of the night scene of Zhengzhou in the process of viewing

create distinctive urban night scene lighting through the control of color

color has an important impact on people's vision and psychology, and the use of urban night scene lighting color must be controlled. Determine the use of color according to the characteristics of each region of the city, and through a comprehensive investigation of the current night scene, make the use of color adapt to the original night scene of the city and highlight the characteristics. Pay attention to the use of color light. Color and lighting are mainly to control excellent resources; In the midstream mode, it is closely related and cannot be misused, such as white and blue for the edge, warm white and yellow for the floodlight. In some places, such as building outlines and signs, colored light can be used, and the flood light in large areas is still mainly white and yellow. Local areas can use more color changes to create a warm and rich atmosphere

through the flexible use of lighting methods and dynamic lighting, enhance the night scenery characteristics of the city

this can be the direction of the future. The combination of lighting methods such as contour, floodlight and internal penetration can be used to highlight the characteristics of lighting objects. The lighting mode should be planned as a whole, and the lighting of the same road section should be enriched on a unified basis. For example, buildings on a section of road may use the top edge to form a unified overall effect. Individual buildings combined with floodlight or signboard lighting show rich effects. Dynamic lighting can be used in commercial areas and public leisure areas to create a rich and lively atmosphere. The billboards in the commercial area are planned and designed in a unified way to avoid a disorderly state

according to the characteristics and conditions of Zhengzhou City, the implementation of nightscape lighting should be carried out by stages

the planning and design of nightscape lighting should put forward the steps of implementation by stages according to the characteristics and current nightscape lighting conditions of Zhengzhou City, so as to make the lighting planning more practical and feasible. For the key nodes that have a great impact on the overall night scene effect or play a finishing touch, lighting shall be implemented first to make the city have a relatively complete night scene, and then lighting in other places shall be carried out gradually. For the lighting of buildings, it should also be carried out step by step according to the importance classification according to the building type and the environment: first, the lighting around the nodes and important buildings, then the lighting of other important buildings on the road section, and finally the lighting of general buildings to form a complete night view of the city

from this, it can be seen that there are many places that can be improved in the general environment of urban lighting in Zhengzhou, and Zhengzhou itself is also actively exploring and waiting for the arrival of a new face. Under this opportunity, under the joint organization of the Aladdin magic lamp award organizing committee and local societies, street lamp houses, engineering companies and other units, the night scene of Zhengzhou was visited and investigated on the spot, and the discussion was carried out in the form of a symposium to make an in-depth discussion on Zhengzhou lighting

at the symposium, Feng Jian, Deputy Secretary General of Henan lighting society, said when introducing the situation of Zhengzhou urban lighting that Zhengzhou urban lighting 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. Among them, the "corn cob" (the shape of the Millennium square building resembles corn cob, so it has this name locally) is a gratifying part. Compared with other cities, it is not so gorgeous and colorful, and its colors are relatively soft, which makes people feel very comfortable. It has also become a landmark building in Zhengzhou

according to Chen Shaohua, the designer of Henan floodlighting Engineering Co., Ltd., Zhengzhou is bright in the East and dark in the west, with obvious regional spatial differentiation. The Eastern District represents the direction of the city's new planning and development. The night scene lighting planning and design is first, with relatively good forward-looking planning. The lighting is better than the overall light environment in the western district. With "corn cob" as the core visual point, it connects the building complex of Ruyi Lake in the entire eastern district, Form a group light with complete volume. Except for the good lighting effect in the eastern CBD area, other areas are relatively insufficient. On the whole, he believes that Zhengzhou's urban lighting may lag behind Beijing, Shanghai, Guangzhou, Shenzhen and other cities for three to five years, and the most impressive thing for outsiders is the "corn cob", but Zhengzhou is the birthplace of multiculturalism. Before the "corn cob", the February 7th memorial tower is the earliest landmark of Zhengzhou and a memory node of the times and even culture. It has a good carrier, a good story and a good historical precipitation, However, at present, the publicity and cultural atmosphere of lighting are not prominent enough. "Don't blindly follow, do lighting with fine quality; slow down and let the road of lighting develop naturally; focus on culture and make night lighting works with the characteristics of the central plains; in the era of multimedia, highlight their own connotation and make the lighting more profound." This is Chen Shaohua's suggestion for Zhengzhou lighting

Liu boxue, the chief designer of Zhengzhou dongzhichen Lighting Design Co., Ltd., expressed his views from a more macro perspective:

based on the volume of Zhengzhou's night scene, he believes that Zhengzhou has not yet established a preliminary night scene system, and the city's roads, boundaries, and signs are very important infrastructure projects, while Zhengzhou's night scene is still in a state of scattered chaos, and 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 aesthetics, and make more quality-oriented and meaningful lighting, this is what he expects

Li Xubo, deputy director of the lighting Institute of Henan General Institute of urban and rural planning and Design Co., Ltd., 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, and its development may depend more on some policy trends in Zhengzhou. "Zhengzhou's economy has developed rapidly in recent years, the entire urban area has been expanding, and the infrastructure has been constantly improved. For lighting, Zhengzhou wants to do better on the shoulders of giants. In 2018, relevant departments also specifically put forward the design and planning intention of the lighting sector, which may be five years late, but when it is really done, it will brighten people's eyes."

from this point of view, Feng Jian mentioned that they found that the relevant government departments in various regions were also confused that there was no clear acceptance standard for infrastructure construction such as road lighting after participating in the night scene lighting survey in various cities. Knowing these conditions, Henan lighting society also planned to cooperate with Henan Provincial Department of housing and urban rural development and Zhengzhou Municipal Engineering Survey and Design Institute, with the help of the LED inspection center of the society, Draft relevant acceptance standards and local road standards, and build a platform to hold short-term service classes with the street lighting department for training, to help improve highly competitive skills and aesthetic ability, and reasonably guide planning; And put forward suggestions on how to adopt a more scientific and reasonable way of later management and maintenance, and analyze the advantages and disadvantages of today's relatively emerging energy management and PPP mode, so that relevant personnel have a more comprehensive understanding

for the commendable Zhengzhou urban lighting, it obviously needs the wisdom of designers, experts, governments and other people to show the charm of the city, so as to avoid entering the ranks of stereotyped and homogeneous cities
