With the continuous warming of environmental protection, energy conservation, and low-carbon issues, and the current global energy shortage, green lighting has become one of the hottest topics. Incandescent lamps consume too much energy, and energy-saving lamps produce mercury pollution. As one of the fourth-generation new energy sources, LED lighting is favored by government companies because of its energy saving, environmental protection and low carbon. Therefore, green buildings and green new cities cannot naturally miss green building lighting. LED lighting is part of green building lighting. The green color of green building does not refer to the three-dimensional greening and roof garden in general. It represents a concept or symbol that the building is harmless to the environment and can make full use of the natural resources of the environment. A building constructed without destroying the basic ecological balance of the environment can also be called sustainable buildings, ecological buildings, returning to nature, energy-saving and environmentally friendly buildings. Architectural lighting is an indispensable part of green building design. Architectural lighting design must conform to the three concepts of green building: energy-saving energy, resource conservation, return to nature, and architectural lighting is the true green building lighting. LEDs can directly convert electricity into light, consume only one-third of the energy of incandescent lamps, achieve the same light efficiency, and use smart sensors and microcontrollers to greatly improve equipment maintenance efficiency and reduce management costs, truly bringing extra Energy saving effect and economic benefit. At the same time, the standard LED lighting life is 2 to 3 times that of energy-saving lamps, and there is no mercury pollution. LED lighting is well-deserved as part of green building lighting. During the 12th Five-Year Plan period, energy conservation, environmental protection, and low carbon have been put on the motion for many times. Local governments have also attached great importance to the development of energy conservation and environmental protection in various industries. Under this circumstance, Shenzhen Guangming New District has built the country's largest green building demonstration zone. The construction of green new city in Guangming New District is changing with each passing day. The city's first municipal road adopting LED lighting system, the city's first underground common trench, the country has assessed and is under construction. The most famous and largest green building demonstration area, these people are very proud of the bright people. According to the Shenzhen Business Daily, Shenzhen Guangming New District is the first green road in the city to adopt LED lighting system. Compared with ordinary lighting, LED lighting can save 80,000 yuan per kilometer per year. In the past three years, all newly built roads in Guangming New District have adopted LED lighting systems. The LED lighting system plays a huge role in saving electricity, saving resources and protecting the environment in the green building demonstration zone. This has played a pilot and exemplary role in introducing LED lighting into green buildings. LED lighting illuminates the era of green architectural lighting It is understood that the average area energy consumption of shopping mall buildings is 223.08kwh/m2 (1kwh kWh = 1 degree), ranking first, while hotel and hotel buildings are ranked 202.99kwh/m2. Two, the hospital building ranked third with 193.87kwh/m2. The rest are government office buildings (183.43kwh/m2), business office buildings (103.96kwh/m2), cultural venues (94.62kwh/m2), and schools (55.24kwh/m2). With the advent of the LED lighting era, LEDs should not only meet the basic energy-saving requirements of buildings, hotels and other buildings. It is also possible to set the illumination parameters of the LED light source component or the lamp itself according to the user's feeling requirements for the LED, because the direct feeling of the user's lighting effect is often due to the difference in the environment configuration, decoration, space and atmosphere. A considerable gap; the comfort and uncomfortable light source performance is not whether the LED lighting has reached the highest lighting output effect. The LED lighting industry must first predict the possible use environment and the way the light source is used before developing the product, so that the LED lighting It can also play a lighting setting that creates an ambient atmosphere or achieves practical use. 1. Energy-saving lighting for large-scale retailing. The large-scale retail industry has the longest uninterrupted lighting time, and the electricity and operating costs are also the highest, so the lighting energy consumption problem is an area of ​​great concern to the industry. Reducing energy consumption is not only the responsibility of the large retail industry for social energy conservation, environmental protection, and low carbon, but also the industry's performance in reducing operating costs, increasing profits, and increasing competitiveness. LED lighting has the advantages of high luminous efficiency and dimming. The large retail industry can design lighting according to the theme of the shopping mall. Through the control of the lighting system and the creation of the lighting atmosphere, the consumers can enjoy a comfortable and unforgettable shopping experience, thus increasing consumption. The desire to buy again. In order to make LED lighting source used in large-scale retail industry, the first retail energy-saving lighting research project in China was launched. It is understood that the research project is led by the University of Cambridge Architecture and Urban Research Center, Tsinghua University School of Architecture and the lighting industry leader Sanxiong. Aurora co-sponsored. The research objective is: on the one hand, it will fill the research gap of China's retail building energy-saving lighting, understand the basic situation of China's retail building lighting energy consumption; on the other hand, it will also provide data for the formulation of China's energy-saving lighting related policies and design specifications. Support to promote the healthy development of the domestic lighting industry. 2. Hotel energy-saving lighting. The hotel is second only to the energy consumption of the mall. In the cost of hotel lighting, the cost of electricity is the highest, followed by labor costs and material costs. The main source of hotel lighting costs is the cost of use, which is the cost of electricity. The initial procurement cost only accounts for 4, therefore, the energy-saving hotel clearly focuses on solving the energy utilization rate of lighting equipment. Secondly, light is the soul of architecture, creating three-dimensional dimensions, spaces and levels, scenes and atmosphere, emphasis and details through light. If hotel lighting can gradually take advantage of the advantages of LED lighting to create a green, home feel, designing a green light experience is not a luxury transformation. On the contrary, this project brings cost savings while also bringing customers. In addition to LED lighting to gradually transform large-scale retail lighting, hotel lighting, you can also gradually transform hospital-style architectural lighting, government business office lighting, cultural venue-style architectural lighting, school-style architectural lighting, etc. according to the characteristics of each field and place. In the near future, LED lighting will light a new era of green architectural lighting. Green building LED lighting needs to pay attention to the problem At present, although LED lighting has the advantages of energy saving, low carbon and environmental protection, it is highly popular by government enterprises. However, due to various environmental factors, there are still many problems in LED lighting. The lack of standards, insufficient supervision and control, disordered industry, and opportunistic investment have resulted in uneven product quality. The quality of the products is uneven, so all green building lighting is a castle in the air. Secondly, excessive LED display advertising caused light pollution and caused complaints from many citizens. Therefore, LED lighting should enter the era of green lighting as soon as possible. This requires LED designers to be people-oriented. For light parameter settings, brightness, softness, color vividness, etc., the human body is comfortable and harmless.
