Value and planning design of urban landscape lighting

Since the 70s of last century, the urban landscape lighting has gradually become a trend in the world, and more and more attention has been paid to it. From the domestic situation, China's rapid urbanization process, to provide adequate support for urban landscape lighting. But there are some problems. First, the city landscape lighting is often driven by big events, because the time is very tight, so the lack of sufficient time for a complete process from the overall planning to lower level planning, lack of capital investment projects, social effects and economic benefits of the feasibility of rigorous, has great randomness. Second, design the lack of evaluation mechanism, often with leadership preferences decision, which led to the city landscape lighting to chase quick success, dramatic effect, leading to the aesthetic landscape lighting tend to "light up beautiful, colorful beauty, the beauty of dynamic flicker". Third, landscape lighting is an emerging industry, the industry is also a lack of an efficient operation mechanism, many practitioners lack of professional training. Orderly city landscape lighting, first of all should be established on the basis of value orientation and value judgment of the good, and then through the stages of clear planning and design content, standardize the process, ensure the implementation process. In order to ensure the lighting planning and design to achieve better results, it is necessary to establish a platform for information exchange, so that designers, manufacturers, owners and other related parties to communicate effectively, reduce the asymmetry of information. The value of urban lighting landscape lighting is a means to enhance the city's appearance, in a short period of time with a relatively small price can bring greater changes to the city. At present, many cities in the implementation of landscape lighting is the main driving force to improve the city's appearance, showing the city a good image. The value of urban landscape lighting is also reflected in the humanities. The first humanistic value is humane care, good lighting can provide people with a better and safer urban living environment. For example, after the three rivers and lakes in Changzhou, the lighting of the intervention, the use of waterfront this feature to create a safe and comfortable living environment for the public. Second humanistic values are to highlight the city's historical heritage and identity. For example, Ningbo City District has a prominent geographical feature is Sanjiang and flow, Yuyao River and Fenghua River in the city of Sanjiang port "Huicheng Yong river, flowing into the East China sea. To seize this characteristic, different rivers are represented by different colors, and the tide and the direction of water flow are deduced by color change, which shows the cultural and geographical characteristics of Ningbo port city. In addition, the illumination not only has the humanities value, increased the city culture information release, but also has the economic efficiency, creates the new value. For example, through the transformation of Longmen Grottoes lighting, stimulate more tourists to watch the night, only 3 months to recover the investment. The reason is that the lighting before the transformation is only trying to restore some of the carrier during the day, did not increase the amount of new information, it is difficult to attract tourists during the day has been traveling again. After the transformation of the lighting, the use of precise control of the virtual projection of the cave with the historical changes of the different historical traces, providing more historical information, given the value of its renewal. This is to promote the development of economy by promoting the development of historical and cultural heritage and tourism. There are several schools on the planning and design of lighting planning: represented by North America, which only focus on energy and security issues; to Europe as a representative, it pays more attention to shaping the aesthetics, city image; and in Asia, Singapore, Seoul city as the representative, it is to implement security as the core, pay close attention to how to implement and corresponding support policy and management system. In China, the concept of lighting planning has not yet been clearly defined, the overall planning is called planning, detailed planning is also known as planning, the final design is still called planning. Lighting planning, which means a more comprehensive long-term lighting plan, divided into several levels. The first is the total city planning, put forward the whole city architecture, lists the important section, raises the relationship of partition management. After the detailed planning of the city, the concept of lighting design throughout the city. After the city planning is the detailed planning of the street, the last is a single floor lighting design. The general plan is presented in the form of two-dimensional drawings, which is intended to establish management plans, detailed planning and design of the theme, image, style, etc., through the detailed planning of the theme set to guide the specific project design. Detailed planning does not emphasize the characteristics of the monomer, but emphasizes the regional common, project design emphasizes monomer or how to achieve the problem. Chongqing Peninsula landscape lighting in Yuzhong, for example, the first priority is to tap the humanities and characteristics of Chongqing. From the natural conditions, Chongqing is surrounded by mountains, near the intersection of two rivers, a large number of the original forest, such geographical conditions make Chongqing often shrouded in mist, thus summed up the hills and water, fog, forest and other features, poetry and painting are also handed down the mountain, water, fog, forest and other elements to describe Chongqing, so we can take these elements as the source intention visual expression. Then, from the planning point of view of the different groups, the establishment of planning, for each group to give a different theme.
