Stages of Urban Landscape Lighting Development
Urban landscape lighting is to reshape the image of the urban landscape at night through freehand techniques, providing a safe, comfortable and romantic light environment for people's night life, and showing the unique charm of the city at night. With the rapid development of urban economy and the improvement of people's aesthetic awareness, urban landscape lighting has become an indispensable part of urban planning. To a certain extent, urban night scene lighting has become a window to display the image of the city and one of the symbols to measure the overall development level of the city. As an important part of urban planning and construction, it not only reflects the degree of economic prosperity of a city, but also reflects the cultural temperament and civilization of the city. It has received more and more attention from government departments and from all sectors of society.
1. The primary stage of urban landscape lighting in China
From the 1980s to the 2008 Olympic Games, China's urban landscape lighting was basically in its infancy. In cities, functional lighting was the mainstay, and there were a few key parks or major festivals with some lantern decorations. In the first- and second-tier cities, some landmark buildings are mainly floodlighted. Using floodlights to illuminate the facades of buildings was the basic method of urban landscape lighting at that time, such as the floodlights of Tiananmen Gate Tower and the decorative bulbs on the top. The lighting fixtures include fluorescent lamps, sodium lamps, metal halide lamps, and a small number of LED lamps. In some cities, LED contour lights and point light sources have been tried, but the product quality of LED lamps has made owners and designers have doubts. Most owners and designers in the industry hold a negative attitude towards the development of LEDs. Due to the high unit price of LED lamps and easy damage, the number of projects used is large, which increases the cost of the project. Therefore, during this period, urban functions and landscape lighting were mainly based on traditional light sources and lamps.
2. The rapid development stage of urban landscape lighting in China
The stage of rapid development of urban landscape lighting in China is from the 2008 Beijing Olympics to 2015. At this stage, the technology of LED lamps and lanterns has gradually matured, and there are gradually more applications in the project. Several major series of wall washers, point light sources, contour lights, flood lights, window lights, buried lights, and underwater lights have professional manufacturer. At the end of 2010, China set off a lighting whirlwind of commercial complexes. Developers represented by Wanda Group led a group of design companies, engineering companies and lighting manufacturers. The lighting engineering investment of commercial complexes often invests more than 10 million yuan, and the huge industry business opportunities allow lighting design companies to fully exercise their design capabilities and standardize their lighting design processes; lighting engineering companies and manufacturers are also due to commercial real estate. The project has increased its own turnover and scale of production and operation. The large-scale use of LED lamps in urban landscape lighting planning is also becoming more and more obvious. The share of commercial complexes and urban overall planning lighting is two important sectors in the entire Chinese urban landscape lighting.
3. The blowout stage of urban landscape lighting in China
With the Hangzhou G20 Summit Landscape Lighting Project as the symbol, it has ignited a new round of blowout climax in China's urban landscape lighting construction. The volume of a single urban landscape lighting project has spanned from hundreds of millions to several billions. At present, Xiamen, Wuhan, Qingdao, Nanchang, Hefei, Xi'an, Urumqi, Taiyuan and other urban landscape lighting investments that have been completed or are being done are in the scale of several billion yuan. According to CSA data, the application scale of semiconductor lighting industry reached 428.6 billion yuan in 2016, of which landscape application lighting accounted for 13.5%, or 57.9 billion yuan. The data from the High-tech Industrial Research Institute also shows that the scale of China's landscape lighting market reached 55.8 billion yuan in 2016, and it is expected to maintain a growth rate of more than 10% during the 13th Five-Year Plan period. The national plan is to cultivate about 1,000 characteristic towns by 2020. At present, 403 towns have been approved. The average investment of a single characteristic town is about 5 billion, and the proportion of landscape lighting is about 2%-3%. The construction of characteristic towns brings about Landscape lighting market space is about 100-450 billion yuan.
