LED lighting products can reduce the energy consumption of green buildings

LED lighting products can reduce the energy consumption of green buildings National Development and Reform Commission and other related departments recently jointly issued the "Semiconductor Lighting Energy-saving Industry Plan", which systematically elaborated the development goals, major tasks, key projects and supporting measures in the LED industry during the "Twelfth Five-Year Plan" period. Problems such as the promotion of LED lighting energy-saving industry, the average annual growth rate should be maintained at about 30%, in 2015 to reach 450 billion yuan, of which LED lighting applications to account for the total proportion of 40%, annual output value reached 180 billion yuan.

The degree of energy saving depends largely on the use of lamps and lanterns in the transformation of energy-saving office buildings in Beijing, some places to reduce the energy consumption and reduce the lights or even turn off the lights. Simply to achieve energy conservation but to reduce the daily effect of light sources, this is a great misconception, and this 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 accessories, it can bring about vast energy-saving space. Just as we can save food, we can't go on a diet because we want to save food. ”

For some particularly large buildings such as exhibition halls, the manual control efficiency is relatively low. If intelligent lighting control is used, the lighting on or off is programmed, and the efficiency is much higher than manual time. Although one-time investment has increased, the long-term energy-saving effect will enable the cost to be recovered within a few years. In the entire life cycle of the building, the user will receive long-term benefits. Of course, for a gas discharge lamp, when a 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 turned on and turned off for several hours. To find a better light source that is not affected by the number of switches, LEDs are a good choice.

The energy saving of the lighting system is a quantitative standard. The most important thing is that the value of the lighting power density cannot exceed the standard value. In the aspect of type selection, the light source with high luminous efficiency, low power consumption accessories, and high-efficiency rectifiers are selected. After careful calculation, the power density value can be even lower than the target value. However, the efficiency of the product selected in the design is even higher. If it is not properly controlled, the energy saving effect will be greatly reduced. The existing lighting control methods include single lamp control, multiple lamp control, building automatic control system control and intelligent control, etc. Many intelligent lighting control systems are set in many projects.

It is for these reasons that LEDs have received increasing attention in architectural lighting. There are many examples of LED lighting used in outdoor lighting, including street lighting, garden lighting, and aviation obstruction lighting. In terms of power supply, there is external power supply, and there is also solar PV integrated power supply. In indoor lighting, there are many applications for emergency evacuation lighting and indication display, and some are used for parking lot lighting. Currently, the number of lightings used in offices, corridors, and stairwells is not much yet, but it has also appeared. Rapidly growing trend.

LED lighting standards and technologies need to be further improved in the domestic standards of architectural lighting and other standards, the lack of LED lighting standards. The requirements for the lamps used inside and outside the building are mainly for specific indicators such as the number of lamps (illuminance, luminous efficiency), lighting quality (evenness, 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 standard formulation of LED lights should cover two aspects: First, the use of LED to gradually promote the standardization and improvement, so that it can continue to promote the use of technology and progress in the next step; The second is to draw on the promotion of foreign countries, specify a series of experiences, and then promote the improvement of domestic standards. It is reported that the "Architectural Lighting Design Standard" under revision will increase the content of LED lighting and further promote the application of LED in China's architectural lighting design.

The mere designation of standards is still far from enough, and technological progress is even more important. "In terms of the optical characteristics of LEDs, long life, high luminous efficiency, ease of control, low energy efficiency, rich colors, and security are all aspects that we would like to see. But we must also pay attention to some of the negative effects of LEDs, such as: Point light source, resulting in concentrated light, high peak light intensity, easy to produce a sense of discomfort, LED color temperature is very wide, product consistency control issues, continuous spectral issues, the impact of discrete spectrum on people need to be further Research 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 promoting green buildings, the designation and popularization of standards must involve the cooperation of various agencies within the industry to promote the use of new technologies. In addition, the understanding of customer needs and the integration of innovation and technology are also important issues in the development process. In our practical experiment, green buildings that integrate energy-efficient, innovative LED design, and mercury-free and lead-free environmental protection goals are undoubtedly the most worthwhile to learn and study in the same industry, among which is located in Building 2 of Philips Shanghai Innovation and Technology Park. The Philips Lighting GBU-LED office area is the best example of a green building.

The project's car is to transform the old factory building, transforming the building into a green office area on the basis of the unchanged building structure. Thanks to the use of a full range of LED lighting systems, the project has been LEED Gold Certified. Throughout the design phase, how the lighting fits into the interior with a high ceiling, how to use the natural light at the top of the plant, and how to change the various forms become the primary problem to be solved in the project. Designers boldly use LED lighting equipment, compared with the monotonous traditional office lighting, hanging lamps and more custom lighting is the biggest design highlights, combined with various types of LED light source, including LED PAR30, LED T8, LED MR16, LED Modules, etc. The ingenious use of circular luminaires, combined with the LED PAR30 light source as the base lighting for the office area. The LED T8 hanging lamps are used in the mezzanine office area to take full account of the illumination and uniformity of the work surface and fully utilize the design space. Adding a lamp above the desk is the finishing touch to the design and the light fill function. The use of color in the pantry and other rest areas makes the space more vibrant.
