Recently, the Tianmeng Lighting Light Source Reconstruction Project of the Great Hall of the People in the Great Hall of the People, which was won by Dongguan Qinshang Optoelectronics Co., Ltd., successfully passed the acceptance test. It is reported that the project is a demonstration project of “energy saving and emission reduction†promoted by the National Development and Reform Commission, which is of great significance for leading the development of the domestic LED lighting industry.
The Great Hall of the People is the place where the Standing Committee of the National People's Congress meets and works. It is an important place for the party and the state to hold political, diplomatic, and social activities, and is also one of the capital's landmark buildings. The construction area of ​​the Great Hall of the People is 171,800 square meters, and the height of the building is two to three times that of the general building. The clearance of the 10,000 people hall is 39 meters and the width of the mouth is 32 meters. Affected by factors such as energy-saving technologies and technologies, and structural and functional factors, energy consumption is higher than that of ordinary large-scale buildings.
In response to the national energy conservation and emission reduction policy and the State Council’s call for “building an energy-saving government and making resource conservation modelsâ€, the Great Hall of the People took the lead in implementing energy-saving renovations and publicizing the energy-saving renovation project for the LED lighting source of the People’s Hall. Tender.
Due to the particularity of the Great Hall of the People, there are very strict requirements for the safety, stability, illumination, color rendering, etc. of the LED lighting fixtures entering it, especially for light and lighting control. The People's Congress Hall Authority and the domestic authorities and experts conducted strict screening of LED lighting fixtures purchased by bidding. With excellent product quality, leading technical level and good brand reputation, Qinshang Optoelectronics stood out from many outstanding LED companies and successfully won the bid for the Tianmen Lighting Light Source Reconstruction Project in the Great Hall of the People.
The person in charge of Qinshang Optoelectronics said that since the project was undertaken, Qin has attached great importance to it and regarded it as a political task. It has integrated resources, at all costs, and regardless of cost. The company is fully committed to complete the lighting renovation of the Great Hall of the People on time and strive for a light environment. The power saving rate and technology have reached the world's leading level. From product development, production to installation and commissioning, Qinshang Optoelectronics staff carefully and carefully do every detail. With the support and support of the Great Hall of the People's Congress, after more than a month of unremitting efforts and close cooperation, the energy-saving renovation project of the LED Hall light source in the Great Hall of the People's Hall has been successfully completed. The quality of the project is in line with national regulations and related. Technical standards requirements.
"Diligence and innovation" to overcome technical difficulties
According to reports, the 10,000-meter auditorium star has 210W, 110W, 60W three kinds of power, the original thyristor dimming mode is required to be used, the light is turned on and the light is neat and consistent, and the brightness changes visually linearly. The person in charge of Qinshang Optoelectronics said that for such high-power LED thyristor dimming lamps and engineering, the industry has not tried before, and the dimming effect is comparable to incandescent lamps, which is a major technical challenge.
"We have conducted in-depth research on the characteristics of thyristor dimming equipment and the setting of dimming curve, and cooperated with the engineering and technical personnel of the Great Hall of the People's Congress to overcome technical difficulties. Finally, we have adopted the expertise of diligent control technology and combined with the mature and reliable routines of famous factories. Power supply, developed a high reliability, ideal dimming driver to meet product drive and control requirements."
The heat dissipation of high-power LED indoor lighting products is also particularly critical. Qinshang Optoelectronics cooperated with Tsinghua University to integrate the overall mesh super-book heat sink, vertical heat dissipation structure, and upper and lower ventilation convection innovation technology to create a "vertical convection heat dissipation structure", making full use of the "chimney effect" of the principle of air thermodynamics, and The LED luminaire is combined with the air outlet of the building fresh air system, and the fresh air system is used for active heat dissipation, thereby effectively avoiding the "heat island effect" and enabling the LED luminaire to achieve an ideal heat dissipation effect.
In the lighting renovation of the Great Hall of the People in the Great Hall of the People, 210W, 110W, 60W LED lamps were used to replace the original 1000W, 500W, 300W incandescent lamps. Although the height of the lamps was more than 30 meters, the light was directly hit. It can achieve very good vertical illumination and brightness. After the transformation, the average horizontal illumination is 2~3 times of the original illumination, and the direct power saving is more than 75%. At the same time, it also reduced the heat radiated by the lamps to the hall about 300KW, which indirectly saved a large amount of air-conditioning electricity, which was well received by the leaders.
