Anhui experience shopping mall LED application is not a dream

In November 28, 2009, a classic ang also building - Anhui Bengbu department store shopping center in front of the world. This seat is composed of Chinese top 500 enterprises of Hefei Baida group to invest in the construction of large-scale retail commercial buildings, the overall use of functional semiconductor lighting our independent research and development "".

According to the investigation, the use of large shopping malls semiconductor lighting, the international front no case. In the country is still the first.

The same day, "ten city lights" reporter interviewed Bengbu to Bengbu, 100 mall logistics department minister Liu Jianhua. Liu Jianhua said: the use of semiconductor lighting market, the overall effect of the average illuminance 400LX, uniformity error is less than 5%, color temperature of 4800 - 5000K, the overall market is full of light texture. "And the original design of lighting lamps using energy-saving lamps, design illumination in 300LX. The use of semiconductor lighting, the ambient illumination to 400LX or more, the consumption of power in the energy-saving lamps on the basis of energy saving more than 75%, and beautiful appearance, the corresponding set off the overall aesthetic environment.

However, for the large-scale application of LED lamps, the mall itself has been a major controversy. What makes Bengbu 100 shopping center determined?

Liu Jianhua admits that he initially did not agree with the use of LED lamps, LED lighting from the lighting circle to hear more negative news. However, the leadership of the group attaches great importance to, let us do a good job of research, with a number of manufacturers to contact manufacturers to send samples, some can meet the requirements, there are some need to improve. One of the most important factor is the energy saving effect is very obvious, saving about 75%. Under the simple conversion, a total of 12000 commercial lighting lamps (each of the two 26W energy saving lamp plus two ballasts 10W), the total power of 62W. Working 13 hours per day, the total daily energy consumption of 9672 degrees, the annual total energy consumption of 3 million 530 thousand degrees. LED lamps are now replaced by the power of 12W per day, saving energy consumption of 7800 degrees, the annual energy consumption can be saved by 2 million 847 thousand degrees.

Reporters later learned that Hefei Baida group has previously been the flagship store in Hefei Gulou commercial application of LED lighting, the result is really good. Chen Bugao, Minister of Logistics Department of the Ministry of Commerce, as a result of energy conservation work, the Hefei Municipal People's government as "2008 annual energy saving advanced individuals".

The reporter saw in the drum tower building, LED floor, the lighting with the Bengbu 100 shopping center, beauty. Chen Bugao high speed reporter: in order to save energy and reduce consumption, we can be described as a headache, the group requires the use of energy consumption per year to reduce 3%. Due to the increase in the number of lamp life, energy consumption, not only can not fall down, but also increased by about 5%, which is one of the drivers. Coupled with the semiconductor lighting manufacturers to provide a lot more expensive than traditional lamps, and we now use the traditional energy-saving lamps and semiconductor lighting compared test, energy saving rate reaches more than 75%, for businesses, saving electricity is to save money. After calculation, after the transformation, the mall can save electricity more than 10 thousand degrees per day, which means that every day can save electricity more than 10000 yuan. Furthermore, the group asked us to set an example, its purpose is to use the energy saving products within the group in order to achieve the overall reduction of the group. "

Chen Bugao also told reporters: after the transformation of the mall lighting is: the average surface illuminance is 600LX, the average error is less than 5%, the naked eye does not feel, color temperature 5500K, the error is less than 5%. After more than half a year of use, the effect is still good. At present, our shopping malls, as well as from the customer to understand the use of semiconductor lighting are recognized. "

For Anhui Province, the first to eat crab who, initially without fear and criticism. Today, the drum tower commercial buildings in Anhui province to become an example of learning. Chen Bugao revealed that the group's more than and 120 stores will follow up the replacement of LED lamps.

In fact, for our mall is zero investment, zero risk. LED manufacturers have 3 year warranty period, within 3 years of depreciation should be controlled within 20%, more than the free replacement. In theory, the life of the LED lamp can be up to 50 thousand hours, which means more than ten years. It takes three years to be conservative. A year and a half of the remaining electricity costs for the cost, as well as a year and a half of revenue. "Chen Bugao" s analysis of the economic value of large-scale LED lighting from the merchant's perspective.

In Hefei, the reporter saw the mall two or three, Qingyun garment four layers are used in LED lighting, Hefei yuan a times square and Anhui business has entered the installation phase, plans to step fully into the semiconductor lighting. Zhou Dongjun, manager of the Engineering Department of Hefei Times Square, said: "after the contrast test between the semiconductor lighting and the traditional lighting, the energy saving rate is as high as 75%. "

In addition, the reporter saw the field of semiconductor lighting Hefei Luogang Airport terminal building, 9.5 meters high hall showing illumination, rich texture according to the introduction, this is the world's first airport building full use of semiconductor lighting civil airport. Another case is located at the intersection of Jade Road and Danxia road Hefei Economic Development Zone, the core area of the City University of golden fairy tale Ming Yuan Xiao Qu real estate projects. This project included in the "11th Five-Year" National Science and technology support program, which is a comprehensive system engineering, the solar photovoltaic power generation, integrated green lighting semiconductor light source application, fire emergency lighting, network management, security monitoring, infrared digital control system and a number of new and high technology, realizes the public lighting electricity of solar energy. This project saves 1 million 110 thousand degrees / year.
