The International (Beijing) International Fencing Center is located at the Beijing National Olympic Sports Center. In response to the national call for energy conservation and emission reduction, the Olympic Sports Center has transformed the night lighting of the fencing hall to achieve the concept of green and energy saving.

The Olympic Sports Center selected the special technical museum for fencing and the physical fitness training complex to make lighting renovation using LEDs. Under the premise of meeting the lighting demand, give full play to the energy-saving performance of LED lamps to maximize energy-saving effects.

  1. Project Overview

The International (Beijing) International Fencing Center is located at the Beijing National Olympic Sports Center. The total area of ​​the venue is 23,000 square meters, including the fencing competition and the fencing combat special hall, the fencing special technology and physical fitness training complex and the adult fencing hall.

Each venue has a separate area of ​​1,500 square meters. At the same time, it is equipped with 50 international standard kendo. The state-of-the-art sports facilities provide students with a world-class professional training environment. .

In response to the national call for energy conservation and emission reduction, the Olympic Sports Center has transformed the night lighting of the fencing hall to achieve the concept of green and energy saving. The Olympic Sports Center selected the special technical museum for fencing and the physical fitness training complex to make lighting renovation using LEDs. Under the premise of meeting the lighting demand, give full play to the energy-saving performance of LED lamps to maximize energy-saving effects. This article will focus on LED lighting applications in the fencing hall lighting applications.

2.Fencing Hall lighting design requirements

The design level average illumination is not less than 750 (lx). U1 (ratio of minimum illuminance to maximum illuminance) ≥ 0.5, U2 (ratio of minimum illuminance to average illuminance) ≥ 0.7. The design vertical average illumination is not less than 500 (lx). U1 (ratio of minimum illuminance to maximum illuminance) ≥ 0.3, U2 (ratio of minimum illuminance to average illuminance) ≥ 0.4. Light source color temperature: 4500K. The glare limit value GR>30. With DALI dimming, the 0% to 100% stepless dimming function of the lamp can be realized.

3.LED lighting design

The ceiling of the Wanguo Fencing Hall is a steel structure, and the lamps are installed at the intersection of the steel structures and are in the form of lifting. The original lamps are 400W metal halide lamps, each with 80 watts of lamps and a total power of 32kW. The installation height is 10m. According to the actual situation of the original fencing hall of the fencing hall, combined with the lighting design requirements, the lamp selection was fully considered, and finally HB-2M 160W LED lamps were selected, totaling 80 sets, the total power was 12.8 kW, and the energy saving rate was as high as 60%.


3.2 Main features of the luminaire

Using a single high-power LED (10W ~ 70W) packaged by independent intellectual property as a light source, using a unique multi-chip integrated single-module light source design, using imported high-brightness semiconductor wafers, with high thermal conductivity, low light decay, light Pure color, no ghosting, etc.

The unique lamp shell heat dissipation integrated design effectively diffuses heat conduction, thereby reducing the temperature inside the lamp body and ensuring the service life of the LED light source for 50,000 hours;

The luminaire reflector adopts a multi-faceted high-reflectance reflector independently designed and developed, and uses different light distribution according to different venues to achieve a good lighting effect.

The whole lamp and power supply of the lamps are certified by TUV, UL and domestic 3C to ensure the reliable operation of the lamps;

3.3 lighting design

According to the scene of the on-site tennis court, the 1:1 computer lighting simulation of the tennis court is carried out, and the simulation data is calculated as follows:
