According to the person in charge of the China Architecture Design and Research Institute, the energy consumption of construction in China is much higher than that of other countries with similar climatic conditions. However, in the construction project, the proportion of energy consumption per construction of a single lighting is relatively high. Therefore, the potential of LED lighting products in the future development of the construction industry, especially in green buildings, is enormous. The National Development and Reform Commission and other relevant departments recently jointly issued the "Semiconductor Lighting Energy Conservation Industry Plan", in which the system's development goals, major tasks, key projects and supporting measures during the 12th Five-Year Plan period were systematically expounded. It is clear that the average annual growth rate of LED lighting energy-saving industry output should be maintained at around 30, and in 2015 it will reach 450 billion yuan, of which LED lighting application products will account for 40% of the total, and the annual output value will reach 180 billion yuan. The degree of energy conservation depends mostly on the use of lamps in the renovation of energy-saving office buildings in Beijing. Some places reduce lighting or even turn off lights to reduce energy consumption. Simply to achieve energy saving but reduce the role of light source on the daily, this is a great misunderstanding, which does not meet our requirements for future development. In fact, lighting energy conservation includes many aspects. Focusing on the application of light sources, lamps and accessory accessories can bring a broad space for energy saving. Just as we save food, we can't go to dieting because we want to save food. For some very large buildings, such as exhibition halls, the efficiency of manual control is relatively low. If intelligent lighting control is adopted, the lighting is turned on or off by program setting, which is much more efficient than manual punctuality. Despite an increase in one-time investments, long-term energy savings can cost back in a matter of years, and users will receive long-term returns throughout the life of the building. Of course, for a gas discharge lamp, when the motion detection control switch is adopted, the life of the light source is greatly affected by the number of times of switching, and the power supply is switched on for a few hours. To find a better source that is unaffected by the number of switching times, LEDs are a good choice. Lighting system energy conservation is a quantitative standard, the most important thing is that the lighting power density value can not exceed the standard value. In the selection, attention is paid to the selection of high-efficiency light sources, low-power accessories and high-efficiency rectifiers. After careful calculation, the power density value can be lower than the target value. However, the products selected in the design are more efficient, and if not properly controlled, the energy-saving effect will be greatly reduced. The existing lighting control methods include single lamp control, multi-lamp control, building automation system control and intelligent control. Many intelligent lighting control systems are installed in many projects. For these reasons, LEDs are receiving increasing attention in architectural lighting. At present, there are many examples of LEDs for outdoor lighting, including street lighting, garden lighting, and aviation obstacle lighting. In the power supply mode, there is external power supply, and there is also solar photovoltaic integrated power supply. In indoor lighting, there are many applications in emergency evacuation lighting and indicating display, and some are used for parking lot lighting. The number of lighting used in offices, corridors, and stairwells is still small, but it is also presented. The trend of rapid growth. LED lighting standards and technologies need to be further improved in the series of domestic architectural lighting standards and other standards, lack of LED lighting standards. Generally, the requirements for the lamps used inside and outside the building are mainly for the number of lamps (illuminance, light efficiency), lighting quality (uniformity, color temperature, color rendering index, etc.), energy saving (LPD) and safety performance. . Zhang Wencai, deputy chief engineer of China Architecture Design and Research Institute, believes that the standardization of LED lights should cover two aspects: First, through the use of LEDs to gradually promote the preparation and improvement of standards, so that we can continue to promote the application and progress of technology in the next step; The second is to draw on foreign promotion, specify a series of experience such as hands, and then promote the improvement of domestic standards. It is reported that the "Architectural Lighting Design Standards" under revision will increase the content of LED lighting and further promote the application of LEDs in architectural lighting design in China. It is not enough to specify the standard alone. The advancement of technology is even more important. In terms of LED optical properties, long life, high luminous efficiency, easy control, low energy efficiency, rich colors, and safety are all aspects we hope to see. But we also need to pay attention to some of the adverse effects of LEDs, such as: LED point light source, resulting in concentrated light, high peak light intensity, easy to create visual discomfort, LED color temperature is very wide, product consistency control problem, spectral Continuous problems, problems with the effects of discontinuous spectra on humans, etc., require further study. This is a difficult problem that needs to be carefully studied and overcome in the future. The innovation and quality of lighting products play an important role in green building. In the process of implementing green buildings, the designation and popularization of standards must cooperate with various institutions in the industry to promote the use of new technologies. In addition, the understanding of customer needs and the integration of innovative technology are also issues that should be taken seriously in the development process. In our actual experiments, green buildings that combine energy-efficient, innovative LED design and mercury-free and lead-free environmental goals are undoubtedly worth learning and research in the same industry, including the 2nd floor of Philips Shanghai Innovation and Technology Park. The office area of ​​the GBU-LED division of Philips Lighting is the best advertised work of a green building. The car of this project is the transformation of the old factory building, transforming the building into a green office area on the basis of the same building structure. The project has received LEED Gold certification due to the full LED lighting system. Throughout the design phase, how the lighting fits into the higher interior of the ceiling, how to use the natural lighting at the top of the plant, and how to change the various forms becomes the primary problem in the project. Designers boldly use LED lighting equipment, compared with the monotonous traditional office area lighting, hanging lamps and more custom lighting is the biggest design highlights, combined with various types of LED light sources, including LEDPAR30, LEDT8, LEDMR16, LED modules, etc. . The ingenious use of circular luminaires, with LEDPAR30 light source as the basic illumination of the office area. The LEDT8 hanging luminaire is used in the mezzanine office area, taking into account the illumination and uniformity of the working surface to make full use of the design space. Adding a desk lamp to the desk is both a finishing touch on the design and a fill-in function. The pantry and other rest areas make full use of color, making the space more vibrant.
