Promotion of energy-efficient lighting should also talk about science

In recent years, the international to speed up the elimination of inefficient lighting products, the voice is getting higher and higher, some developed countries have announced the elimination of incandescent time plan. As a response to the international community of incandescent lamp Chinese trend, promote the green lighting project, the national development and Reform Commission and the UNDP GEF, designed the "Chinese phasing out incandescent lamps and energy saving lamps promotion" projects, the project implementation period of 2009-2012 years, GEF grants $14 million. The main contents of the project is to study the elimination of incandescent lamps in China, the promotion of energy-saving lamps roadmap and special planning, accelerate the transformation of China's incandescent lamp production enterprises to promote the popularization of energy-saving lamps. In 1996, the Chinese government began to organize the implementation of the green lighting project, including the "95", "fifteen" key areas of energy conservation and the "11th Five-Year" key energy saving projects. We in the nationwide promotion of energy-saving lamps 62 million, this year's promotion task is 120 million, this work is organized around the country.

Lighting energy conservation is not only a concept, but also pay attention to scientific energy conservation

Lighting in the field of energy conservation has long been not a new topic. Lighting energy conservation is not only a concept, but also pay attention to scientific energy conservation. The current promotion of energy-saving lamps, the official name is "rare earth three primary compact fluorescent lamp". Mainly to the lamp filament heating through the ballast, when the temperature reaches 1160K, the filament began to emit electrons (because the filament painted some electronic powder), non elastic collision of electron collision of argon atom, argon atom collision energy and impact were obtained after Mercury, mercury atoms transition after absorbing energy from ionization. A 253.7nm ultraviolet, UV excited phosphor.

The use of energy-saving lamps and lanterns to eliminate incandescent lamps is an inevitable trend of development, many countries have already set out a timetable. However, the use of incandescent lamps are to be replaced by compact fluorescent lamps, it also requires a scientific demonstration. Chinese Research Institute of building science building optical research director Li Tienan analysis said: compact fluorescent lamp has the advantage of small volume, easy installation, easy replacement, for the people, the compact fluorescent lamp can be used directly screwed to the incandescent lamp base on the original, but it is more energy saving compared to incandescent lamp, so as incandescent lamp for promotion.

Director Li Tienan believes that each product has its advantages and disadvantages, also has its application area and range of compact fluorescent lamp is the same, it is mainly suitable for corridor lamp, floor lamp, table lamp and a relatively narrow range of local space. It's energy efficiency than straight tube fluorescent lamp, and color and less than the ceramic metal halide lamp, therefore, if the space in the large conference room, offices, shopping malls, compact fluorescent lamp is not the most ideal choice. The industry should pay more attention to the use of various energy sources, and vigorously promote the publicity and is suitable for various places of the different types of energy-saving light source, so consumers do not understand the concept of energy-saving lamp, because of ignorance and waste.

Energy conservation should meet the functional requirements

Functional - Comfort - decoration, this is the pursuit of the goal of the lighting design, that is to say, lighting the first to meet the functional requirements, we can not because of such as the function of the product at a discount, only through the development of science and technology and product performance increase, to achieve energy saving to meet the functional basis on. Lighting is the basic requirement of energy saving according to the functional requirements

Design, use and management of the whole process of energy saving

China is a large country with a large population, and the consumption of all kinds of resources is also very large. Therefore, we must pay attention to energy saving in the whole process of design, production and use. The optical design of the lamp is very important, for example, even the light efficiency is high, but if the lamp light distribution is not suitable, the efficiency of the reflector is not high also will have a great impact on the efficiency of lighting lamps, so the control effect is very important. Therefore, the use of products to be targeted, the design should use the mind, talk about the law, scientific computing in order to achieve a true scientific lighting energy.
