Li Tienan, Director of the Architectural Optics Research Office of the China Academy of Building Research, participated in the 2008 International Lighting Exhibition in China
On April 6-11, 2008, the biennial Frankfurt International Lighting and Building Technology and Equipment Exhibition opened in Frankfurt, Germany. At the China Information Day Conference held on April 8th, Mr. Li Tienan, Director of the Architectural Optics Research Office of the China Academy of Building Research, explained the trends and prospects of LED and green lighting in China on the theme of “Energy Efficiencyâ€, including LED lighting in China. The speech, standards, lighting design, light source selection, demand, control, application, etc. The following is a speech by Mr. Li Tienan for the Aladdin Lighting Network.
The concept of green lighting was proposed by the US Environmental Protection Agency in 1991. After 16 years of implementation, it has achieved great influence in the world. It has also been carried out almost simultaneously in China, and has achieved good social, economic and environmental benefits. .
The purpose of green lighting: saving energy, protecting the environment, improving the quality of the lighting environment
The content of green lighting includes: through scientific lighting design, using high-efficiency, long-life, safe and stable lighting electrical products to improve people's work, study, living conditions and quality, thus creating an efficient, comfortable and safe, The economic environment fully reflects the lighting of modern civilization
I. China's work in green lighting
China's work in green lighting mainly includes: setting energy-saving standards, researching and developing energy-saving products, developing clean energy, emphasizing the role of lighting design, implementing energy-saving projects, and strengthening the operation and management of lighting systems.
1 Emphasize the concept of green lighting in the standard specification
(1) Design criteria
In a series of standards developed and revised,
â— Increase energy-saving content (including specifying lighting power density, proposing lighting energy-saving measures, etc.)
â—Propose high quality lighting design target requirements
â— Emphasis on scientific design
(2) Product standards
◠Developed a series of standards for energy efficiency limits and energy efficiency evaluation values ​​for light sources and ballasts.
â— Grading according to the energy efficiency of the product
â— Require lighting products to meet the requirements of energy-saving standards in stages and within a time limit
For products, they should be used according to their performance indicators, such as:
â— Use of high pressure sodium lamps in road lighting
(High-pressure sodium lamp has high luminous efficiency and long service life, which is very in line with the requirements of lighting indicators related to motor vehicle road lighting),
â— Use of thin tube diameter fluorescent lamps in office lighting
(At present, domestic lighting design is very fond of using compact fluorescent lamps (commonly known as "energy-saving lamps") to do general lighting sources for office buildings, commercial buildings, etc. - think that "energy-saving lamps" have good energy-saving effects, in fact, thin-tube fluorescent lamps The performance is better than the "energy saving lamp"
â— Lamp type and light distribution requirements in various places
(Only when the type of lamps is selected correctly and the light distribution is reasonable, the energy-saving effect can be achieved, and at the same time, the required light environment can be formed in a targeted manner)
â— luminaire efficiency and safety performance requirements, etc.
