5 years can not accept the LED China lighting power status will disappear?

How the development trend of LED at the present stage, the generic alternative product schedule are already clear? LED could usher in a government subsidy era? Recently, in the Forum on the development of lighting industry field Chinese underground parking, national semiconductor lighting engineering research and Industry Alliance Secretary General Wu Ling, Chinese electrical architectural design and research Institute chief engineer Zhang Wencai industry experts have analyzed and given a clear answer. "If Chinese engage in traditional lighting companies can not accept LED in the next 5 years, the traditional Chinese lighting power status will disappear" China electrical architectural design and Research Institute chief engineer Zhang Wencai said that China's building energy consumption accounts for 27.8% of the total primary energy consumption is about 3 times, basically the same latitude countries. In this one, lighting accounts for the proportion in the energy consumption and the front: specifically, 40%~50% ventilation energy consumption in total energy consumption, lighting energy consumption accounted for about 20%~30%, water supply and drainage energy consumption accounted for 10%~15%, other power consumption accounts for about 10%~15% lighting, ranking second. Therefore, the lighting industry has considerable potential for energy saving. However, Zhang Wencai found in the energy saving renovation of office buildings in Beijing City, some units in order to reduce energy consumption and even fewer lights do not turn on the lights, only to realize energy saving and cannot meet the visual requirements, this is a misunderstanding, it is not advisable. There are many aspects of lighting energy saving, attention to the light source, lamps and accessories, the application can bring a wide range of energy-saving space, lighting control from the point of view there are a variety of ways to achieve energy saving. "He said," of course, the gas discharge lamp, when using the mobile detection control switch, light source life is greatly affected by the number of switches, a switch is equivalent to light for several hours, so to find a better light from the light switch frequency, LED is a good choice. It is for these reasons, LED in the construction of lighting has been increasingly concerned. At present, there are many examples of outdoor lighting using LED, including street lighting, garden lighting, aviation obstruction lights, etc.. From the power supply mode, there are external power supply, but also the use of solar photovoltaic power supply. In indoor lighting, used in emergency evacuation lighting and display areas more, and for the parking lot for lighting, office lighting, corridor, stair the number is not much, but also showing a trend of rapid growth. National semiconductor lighting engineering research and Industry Alliance Secretary General Wu Ling said that the current energy-saving lamp, 80% of the world's China is in production, but if Chinese engage in traditional lighting companies can not accept LED in the next 5 years, realize the upgrading and transformation, so Chinese lighting traditional big country status will disappear. According to PHILPS's forecast, to 2015, the sales revenue of 50% come from LED, to 2020 this revenue will account for the total sales revenue of 80%, this may explain the huge influence on the LED lighting market in the future.

"LED instead of general lighting products has also become an important basis for this timetable," promulgated by the state financial subsidy policy, Wu Ling said, LED products showing explosive growth, the integration speed, for 5 consecutive years, LED growth rate of more than 30%, the industry reached 120 billion yuan, more than 4000 enterprises. The next 5 years, its growth rate will remain at 38%~40%, while the company's investment in recent years is expected to see revenue in the next 2 years. Wu Ling stressed that the state's fiscal subsidy policy will also be based on the general LED product replacement schedule and gradually surfaced. Different manufacturers of LED products, or even the same manufacturer of different specifications of the product interface are different. China's LED standards, testing and certification system needs to be improved "Zhang Wencai said that at present China related standards about LED from the beginning of 2005, mainly for the light source, lamp holder, lamp, LED light control device, safety and so on, but as the LED lighting Standard Guide for lighting design of buildings has been in a blank. He believes that the development of standards should include two aspects: first, through the application to promote the preparation and improvement of standards, and in turn promote the application and progress of technology. Two is to draw on international related technology, to promote the progress of domestic standards. He said that in the "architectural lighting design standards," the revision, it will increase the content of LED lighting, to promote the application of LED in China's lighting design. In addition to standards, technological progress is the most important. "In terms of its optical properties, high luminous efficiency, long life, low energy efficiency, rich colors, ease of control, safety and so on is what we want to see. But we also need to pay attention to, because LED is a point light source, light concentration, high peak light intensity, easy to produce a sense of visual comfort, which is the future need to seriously study and overcome. In addition, the color rendering should be improved at low color temperature. The color temperature of LED is very wide, the consistency control of the product, the continuity of the spectrum, the influence of the discontinuous spectrum on the human need to be further studied. Zhang Wencai said. Wu Ling also said that the current standard method LED detection equipment is not unified, lag, "we see that different manufacturers of LED products, or even the same manufacturers of different specifications of the product interface is different, which reflects the lack of our LED standards, testing and certification system. In addition, the lack of technical personnel, the lack of public R & D platform, key materials, key equipment, key technologies, such as the lag of the current stage of development. "For the future, Wu Ling said
