Experts from all walks of life such as China Lighting Society, China Academy of Building Research and Tsinghua University are optimistic about the development of China's lighting industry. Li Tienan, director of the Architectural Optics Research Office of the China Academy of Building Research, and other experts believe that the development trend of the Chinese lighting industry presents a good momentum of lighting, engineering and design.
Development of lighting fixtures
The development trend of lighting fixtures is LED, and the tide is unstoppable. This tide can be traced back to 2010. The statistics of the United Nations Global Green Energy Conservation Committee at the end of 2010 show that global lighting power consumption is 20% of total annual electricity consumption, but only 10% of electricity is converted into light energy, and another 90% It became a waste of heat. At the Copenhagen Global Climate Change Conference, heads of state made a solemn commitment to reducing their carbon emissions. The reduction of energy waste in the field of lighting is undoubtedly one of the priorities of energy conservation and emission reduction.
Take the Guangzhou TV Tower as an example. It uses 6 696 sets of 55 W LED lamps and 44 sets of 300 W LED light fixtures. The effect is dazzling, but the facade power is only 5 W/m2. In normal operation, the 1 hour electricity fee is less than 1000. Yuan, more than 1/2 energy saving than traditional lighting solutions, only 1/3 of the national standard.
Professor Xiao Huiqian, consultant and chief engineer of the Institute of Physics, China Academy of Building Research pointed out that as an alternative to traditional lamps, LED lighting has broad prospects for development. The development, production, promotion and use of LED lamps with high energy-saving, long-life, high-efficiency and superior color rendering have become the top priority of lighting manufacturers.
Since China's LED output value exceeded 10 billion yuan in 2003, it has increased by 30% annually in recent years. In 2010, the LED market showed an explosive trend. Cree's technology breakthrough, ten cities, Shanghai World Expo 1 billion LEDs and Guangzhou Asian Games bright project, as well as Samsung, Panasonic and other large enterprises have entered the LED lighting industry, the industry hotspots.
In recent years, domestic LED lamps still show a trend of continuous development, and their main driving forces are as follows:
First, there will be further strong growth in the domestic LED lighting market. LED lighting will be increasingly used in various areas such as municipal construction, public facilities, landscapes, private decoration, and electronic products. In particular, the gorgeous turn of LED from the commercial market to the general market has suffocated the expectations of all practitioners.
Second, the state's policies and regulations provide strong support for the development of the industry. During the "Twelfth Five-Year Plan" period, Premier Wen Jiabao presided over the State Council executive meeting to review and pass the "Decision of the State Council on Accelerating the Cultivation and Development of Strategic Emerging Industries" in principle, and semiconductor lighting was among them. This year's "Made in China 2025" and other policies have also greatly supported the LED industry.
Third, the LED product technology continues to improve, the price is gradually reduced, and it has more powerful competitiveness. In recent years, LED packaging COB, CSP and other technologies have become hot spots, LED products continue to make breakthroughs in light efficiency. It is foreseeable that in the future, more efficient and cheaper light-emitting chips will be introduced in the market, and the price disadvantage of LED lighting compared to conventional lighting will be gradually improved. Of course, at the same time, experts also mentioned that China's LED lighting industry is also facing the "bottleneck" problem of lack of core technology, lack of talent, rapid expansion of LED production capacity, and also accumulate the risk of overheating in the industry.
Development trend of lighting project
The trend of lighting engineering is from key breakthroughs to blooming everywhere. Before China in 2002, almost no one knew why a building needed a professional lighting designer. The lighting project was not isolated from the architectural design and interior design as it is today.
Looking back on the development of China's lighting design, Zhimei Lighting's chief lighting designer said: "At the 2008 Beijing Olympic Games, after the lighting art shines, the Chinese city night scene lighting project has mushroomed and quickly matured the lighting. Act as a ". In recent years, the central government has issued a multi- trillion yuan investment plan to stimulate consumer demand such as infrastructure construction and urbanization, which has created a large demand for urban lighting projects.
After the 2010 Shanghai World Expo and the Guangzhou Asian Games, the brilliant lighting project strengthened the government's emphasis on lighting projects, and cities have intensified their efforts to build night scenes. From the current urban lighting projects completed, under construction and planned in various places, the large-scale domestic lighting project has formed the development trend of “central radiation, Xinghuoyuanyuanâ€, with Beijing, Shanghai and Guangzhou as the axis, radiating to the east, Central and western, major provinces and cities.
Beijing, Shanghai and Guangzhou are the hottest sources of this round of lighting projects. In the Beijing Olympic Games, the Bird's Nest and the Water Cube first suffocated their appetites and became an important night view of Beijing after the Olympics. The Shanghai Expo lighting also showed the blending side of the East and West in the night scene of this international city; The opening and closing of the 16th Guangzhou Asian Games will show the night and day paintings on both sides of the Pearl River in front of the world. Under the influence of the Bird's Nest, the China Pavilion, and the "small waist", local governments have continuously increased their investment in lighting projects.
In the eastern region, a number of national key lighting projects along the Suzhou River in Shanghai, Zhejiang Dinghai Waterfront Park, and Shantou City Lighting have been completed. Local governments have invested hundreds of millions of dollars to create a night view of the city. In the central and western regions, Harbin “Dongdonghui†and Zhengzhou Zhengkai Avenue are also the focus of the lighting project, while Chongqing invested 30 million yuan to make the Jiangbei business district a city night sign, and Shaanxi’s 38 million yuan to illuminate the west. At the high speed and Guilin, on the occasion of the 50th anniversary of the establishment of the Guangxi Zhuang Autonomous Region, the investment of 16 million yuan to improve the urban lighting system is also a big step in the lighting project.
From the eastern region to the western region, the beautification effect of the big city will be transmitted to small cities. From the key breakthrough to the blooming everywhere, the lighting project on the Chinese map will gradually form a star fire and light the trend of the land of China.
Trend of lighting design
The trend of lighting design is a dynamic evolution between independence and integration. Lighting design was originally part of the architectural and landscape decoration. From the United States in the 1950s, it gradually separated into a separate industry and found its place in the design field.
For a long time in China, there was neither an independent lighting design company nor a lighting designer. Until 2005, domestic lighting projects started, and lighting design developed independently. From accessory decoration projects to independent categories, to architecture, landscape, and decoration, lighting design has evolved from elementalization to independence and integration.
According to Professor Zhan Qingxuan, a doctoral supervisor at the School of Architecture of Tsinghua University, the original domestic lighting design department was brought back by foreign designers, which promoted the development and improvement of Chinese lighting design. However, in recent years, the three lighting forces that have really influenced China's lighting design pattern are from colleges, independent lighting design companies and lighting engineering companies. They have developed independently on China's huge lighting layout and are organically integrated in major engineering projects and research fields. Form a situation in which the three major schools develop together.
(1) College. As the name implies, it is a school represented by schools, institutes, research institutes, and design institutes. The characteristics of the school are authoritative and professional. Representatives include Professor Zhan Qingxuan and Professor Rong Halei from Tsinghua University, Professor Xiao Huigan from the China Academy of Building Research, and Zheng Jianwei from the Beijing Architectural Design Institute. The college is professional and authoritative, but the number is very small. Usually the academic designers are very busy, but it is still difficult to meet the huge demand for high-end project lighting design, so the general project may not fall into the academic eye of the academic experts.
(2) Independent lighting design company. Independent lighting design companies are generally practical enterprises, relying on their own strength to climb in the market, all the way up. Zhimei Lighting Chief Lighting Designer Ren Jian pointed out: "Although the history of independent lighting design companies in China is not comparable to that of foreign countries, we have established ourselves with professionalism and excellent design strength. This is also the fact that Zhimei Lighting has won more than 260 important countries in the country for many years. The key to the project owner's approval."
(3) Design team of lighting engineering company. Domestic large-scale lighting engineering companies, with strong capital and authoritative qualifications, are able to independently and flexibly integrate existing domestic resources and invest in engineering construction. They have rich experience in design and construction. The downside is that their personnel are relatively independent in terms of professionalism. In the actual operation process, they lack flexibility for more professional lighting companies. These companies are also active in the current high-end lighting design projects in China.
In 2015, China's lighting industry maintained a high-speed development. Whether it is the LED lighting industry that has seized the market share, or the renovation project, the endless stream of lighting projects, or the local lighting design team that is the new and high-end design road, it will face more. Great opportunities, and in the attitude of "three carriages and driving together", galloping in the Chinese lighting market, staged a colorful show.
