LED illuminates the Great Hall of the ground on the innovative "reaffirmed

A few days ago, Gypsophila million people in the auditorium of the Great Hall of the People from Dongguan Kingsun Optoelectronics Co., Ltd. won the tender and complete lighting source reconstruction project passed the acceptance. It is reported that the project is energy saving demonstration project, promoted by the National Development and Reform Commission for leading the development of the domestic LED lighting industry is of great significance.

LED lamps illuminate the Great Hall of the People

Great Hall of the People is the place of the Standing Committee of the National People's Congress meetings and office, the party and the country held an important place for political, diplomatic, social activities, is also the capital of one of the landmark buildings. 171,800 square meters of gross floor area of ​​the Great Hall of the People, the height is 2-3 times the general building million auditorium clearance of 39 meters, 32 meters wide proscenium. Subject to the restrictions and structure of completed years of energy-saving technology, technology and other factors, the reasons of function, the energy consumption is higher than the ordinary large buildings.

National energy conservation policy and the State Council issued the call for the construction of energy-efficient government, do resource savings exemplary "in response to the Great Hall of the lead in implementing energy saving, publicly million people in the auditorium of the Great Hall of the People Starry LED light source, energy saving project tender.

Due to the special nature of the Great Hall of the People on the security and stability into the LED lighting, illumination, color and so on have very strict requirements, especially in terms of lighting and lighting controls. Great Hall of Administration Meeting with domestic authorities and experts on LED lighting bidding rigorous screening. Ground on photovoltaic With superior product quality, leading technology and good brand reputation to stand out from the many excellent LED enterprises, the successful bidder for the Great Hall of the people auditorium Gypsophila lighting source reconstruction project.

The person in charge of the ground on photovoltaic undertake the project from the ground on the attach great importance to and as a political task, integration of resources, at all costs, regardless of the cost to move full time to complete lighting renovation of the Great Hall of the People, and strive to light environment , the saving rate and the technology has reached the world leading level. From product development, production, installation and commissioning of the ground on photovoltaic staff is careful to every detail. In the Great Hall of the support and cooperation of the Authority, and after various team more than a month since the unremitting efforts and working closely million people in the auditorium of the Great Hall of the People Starry LED light source, energy-saving renovation project has been successfully completed, the quality of the project in line with national norms and related technical standards.

Overcome the technical difficulties of handling on innovation "

According to reports, the people auditorium Starry lamps 210W, 110W, 60W3 kinds of power requires to follow original SCR dimming mode, turn on the lights the lights neatly consistency, brightness change visual high linearity. Ground on photovoltaic relevant responsible person said, for this type of high-power LED TRIAC dimming lamps and engineering, before the industry has not tried, and the dimming effect is comparable with incandescent, is a major technical challenge.

"We go through the device characteristics of SCR dimming and dimming curve settings, in-depth research to overcome technical difficulties with the Great Hall of the engineering and technical personnel of the Authority, and finally to the ground on the control technology expertise, combined with the famous factory mature and reliable conventional power supplies, developed a high reliability, the ideal drive dimming effect, meet product drive and control requirements. "

The heat of the high-power LED indoor lighting products are particularly critical. Ground on photovoltaic cooperation with Tsinghua University, and integration into the overall mesh book super heatsink vertical heat dissipation structure, the bottom ventilation convection innovative technologies to create "vertical convection cooling structure, make full use of the the air thermodynamic principles" chimney effect ", and LED lamps with building new wind system vent combination of active cooling fresh air system, effectively avoid the "heat island effect", the LED lamps achieve the desired cooling effect.

Auditorium lighting renovation of the Great Hall of the people on the ground using the 210W, 110W, 60WLED lamps replace the original 1000W, 500W, 300W incandescent, the height of the lights installed in more than 30 meters, but light directly play down, still After the transformation, the average level of illumination of 2 to 3 times the original illumination, and direct power saving up to 75% or more can achieve very good vertical illuminance and luminance. It also reduces the heat radiation of the lamps to the synagogue about 300KW indirectly save a lot of air conditioning electricity, leading praise.

Qin donated free of charge on the lights to support energy saving

At the same time, the ground on photovoltaic also subject completed the three districts of the Great Hall of the seven rooms and one hall renovation project of LED lighting source, more than 30,000 lights and LED tubes, LED downlights, LED petals lights and other donations, to the people Hall. It is understood that the completion of the ground on photovoltaic 60th anniversary parade oversize LED display engineering, large LED display project of the National Grand Theatre "Road to Revival", 120 km Shenzhen Expressway LED street lamps and tunnel lighting engineering, Shenzhen landmark Beijing base 100 lighting and indoor lighting project and other large projects.
