The National Ministry of Housing and Urban-Rural Development issued the “12th Five-Year Plan for Urban Green Lighting Program Outline†(hereinafter abbreviated as Outline) on November 4, 2011, mainly explaining the guiding ideology, basic principles, and development goals of urban green lighting. The key work and safeguard measures are the basis for the implementation of urban green lighting during the “Twelfth Five-Year Plan†period. What are the new features of the program outline and what contents are worthy of attention from LED lighting companies? What opportunities and requirements will be brought to the LED industry? These are important issues that we are concerned about from the perspective of macroeconomic policies.
Guaranteeing the quality of lighting is a basic starting point in the premise outline that the green lighting of the city is to protect and improve the people's livelihood, and emphasizes the basic principle of energy conservation under the premise of guaranteeing the quality of lighting. For LED light sources, the concept of energy conservation has been promoted. At present, the application of LED in lighting is in the initial penetration stage. The quality assurance of products is the core foundation for the survival and development of enterprises, and it has a great influence on the promotion of the market in the early stage and the formation of consumer word of mouth. In fact, companies that can achieve long-term development have strong product advantages.
In terms of lighting quality control standards, the outline points out that the brightness or illuminance, uniformity, glare limit value, environment ratio, and lighting power density (LPD) of urban road lighting should meet the requirements of the "City Lighting Design Standards" (CJJ45). . The LED company's products should meet the relevant standards, and at the same time, they should also make in-depth consideration of the lighting environment, color temperature, and environmental contrast according to the specific road lighting environment.
Energy-saving requirements are still urgently outlined in the outline stipulating the energy-saving goals to be achieved during the “Twelfth Five-Year Plan†period, that is, based on 2010 as the base, and by the end of the “Twelfth Five-Year Planâ€, the urban lighting energy-saving rate will reach 15%. Recalling the “Eleventh Five-Year Planâ€, its energy-saving goal is 25%, but the 2010 energy-saving inspection showed that only 14.6% of the energy-saving rate was achieved. The "Eleventh Five-Year" energy-saving goal has not been fully realized, so the energy-saving pressure during the "12th Five-Year Plan" period is still large.
At the same time, in respect of the construction and maintenance of lighting facilities, the outline points out that the unlighted area should be basically eliminated; the lighting rate of newly installed, reconstructed and expanded urban roads should reach 100%; the lighting rate of road lighting main roads should reach 98%. The lighting rate of arterial roads and branch roads should reach 96%; the intact rate of road lighting facilities should reach 95%, and the landscape lighting degree Celsius hungry rate should reach 90%. On the one hand, it is the guarantee of huge lighting facilities. On the other hand, it is necessary to achieve energy saving goals and requirements. First of all, it is necessary to start from the energy-efficient light source itself. This provides opportunities for more energy-efficient LED light sources and requires scientific planning and design. And the management of the whole process.
The outline also specifies the target responsibility for energy conservation at all levels of government and at all levels of urban lighting authorities, and incorporates urban lighting assessment into the government work evaluation system.
LED road lighting system light efficiency is not less than 90lm/W
To build a "12th Five-Year" green city lighting environment, the requirements for energy-efficient light sources are clear. The outline stipulates that the application rate of high luminous efficacy and long-life light sources in urban lighting shall not be less than 90%. Under the premise of satisfying the light distribution requirements, the efficiency of road lighting fixtures of high-pressure sodium lamps and metal halide lamp light sources is not less than 75%, and the system performance of LED road lighting fixtures is not less than 90 lm/W. The power factor of the lighting circuit is not less than 0.85. It is forbidden to use high-energy-consumption, low-efficiency lighting facilities and products in new projects, and to completely eliminate low-efficiency, high-consumption lighting products in urban lighting within two years.
Insiders pointed out that high light efficiency long-life light source generally refers to light efficiency of 75lm / W, life expectancy of more than 5,000 hours of light, high-pressure sodium lamp and LED are high light efficiency light source. The indicator that the efficiency of the lamp is not lower than 75% can satisfy the high-pressure sodium lamp, and the efficiency of the metal halide lamp is 50% to 60% on average, and it is still difficult to meet the requirements. At present, the system efficiency of LED street light reaches 90lm/W, and the difficulty is not too great. The power factor of the lighting circuit is not high and it is relatively easy to meet. From the point of view of the specific requirements of road lighting, LED street lighting products still have a great opportunity. Only enterprises need to meet the light effect, play LED directional light, but also pay attention to the light distribution and lamp life and other issues.
Zhao Jianping, vice president of the Institute of Architectural and Environmental Energy Research of the Chinese Academy of Building Research, pointed out at the 8th China Road Lighting Forum that the “12th Five-Year†urban green lighting plan’s attitude toward new products, technologies, and methods is: Pilot demonstration . During the “Twelfth Five-Year Plan†period, semiconductor lighting demonstration and promotion will be accelerated to study and formulate relevant application technical conditions or guidelines. When conditions are ripe, “appropriately gradually expand the application†and “encourage qualified and professional energy-saving companies to ensure the quality of urban lighting. Under the premise of participating in the energy-saving transformation of urban lighting." Through the demonstration project to guide the healthy development of the city's green lighting industry and the promotion of lighting new products and new technologies.
