1. Project Overview <br> Ningbo Beilun Arts Center (New arts museum) is located in the west of the city center too River Road, Huangshan Road, south of planning land, with a total investment of 230 million yuan, covers an area of 69,600 square meters With a total construction area of ​​29,700 square meters and nearly 8,000 seats, it is the largest membrane roofing stadium in China. The project is designed by Shanghai Architectural Design and Research Institute. It looks like a shell. It is a member of the Chinese Academy of Engineering and the famous stadium architect Wei Dunshan. Hosted.
The pavilion will be the home of the Chinese women's volleyball team from 2005 to 2008. The China International Women's Volleyball Classic will be held in May 2005. The World Women's Volleyball Grand Prix will be held in June 2005. The 2006 World Women's Volleyball Championship Qualifying Tournament will be held in August 2005. Here, we mainly introduce the lighting design of the main venue. 
2. Requirements <br> body art center staff to participate in the indoor game is divided into the following categories:
-- Athletes - referees, delegation officials - TV, film crew, journalists - audiences, including the audience and the off-site TV viewers. Among these categories, athletes, referees and delegation officials are direct The key personnel involved in the competition must be aware of all the things happening on the venue, and the audience must have visual, auditory and security requirements for the entrance and exit, TV and HDTV broadcast, whether it is the normal picture of the game or the close-up of the athletes and the audience. The lighting should provide good color performance and stereo effect.
3. Indoor sports classification <br> to achieve good indoor lighting effects, from the design function of body art center, indoor sports will be divided into the following categories:
Amateur level:
-- Physical training: Volleyball training, handball training - non-competition, and professional level of entertainment:
-- Domestic competition: volleyball professional competition, handball professional competition
-- International competitions, domestic and international competitions with television or high-definition television: volleyball color TV broadcast
4. Selection of lighting fixtures <br> in the selection and design of lighting, the owners take into account the different brands, different types of lamps, their design and fabric lamp mode has a greater difference. Therefore, Ningbo Beilun Sports Center uses open tendering to select lamps and design schemes. Through program comparison, combined with the scene of the body art center, it can meet the horizontal illumination of the illumination, the vertical illumination of the camera direction, the illumination uniformity U1 and U2, and the glare. The index standard such as index GR and illuminance gradient finally determined the design of Jinchao Lighting Technology Co., Ltd. The program uses the ATON series of 1000W luminaires in the GP brand range (a variety of light distribution curves are available).
Compliant with EN6598-1 CEI34-33IMO, CE standard lamp body, frame, back cover are high pressure cast aluminum material surface RAL7021 gray spray 4mm thick transparent tempered glass shell protection grade IP65, can effectively prevent dust,
Contaminants enter the 99.85% high-purity Yang-grade aluminum lamp, and the built-in anti-glare device is used to open the replacement light source. It is more convenient to maintain and configure the split electrical box and compensation capacitor. The power factor of the lamp is greater than 0.85.
Equipped with sight and angle plate for easy installation and maintenance, safe and reliable 
5. The choice of light source in claim <br> following principles:
-- Color rendering and color characteristics - power of light source, luminous flux - life of light source - cost and maintenance cost of light source The main lighting of this venue chooses the imported light source of Osram, Germany, which is a double-ended metal halide lamp.
6. Emergency lighting <br> not interrupt play and television to ensure that an electricity blackout, the main stadium sports venues set up emergency lighting. The emergency lighting power supply for accidents is supplied by the EPS backup power supply. When the utility power is cut off, 30 sets of iodine-tungsten lamps (TF300) will be powered by the EPS backup power supply to ensure a certain illumination. The illumination of the site during emergency lighting is >35Lux.
7. Lighting arrangement <br> Beilun Arts Center clean, architect on the design of the horse track are very different from conventional stadium, horse Road Arts Center is located directly above the site, a horse track and sports fields to the long side of the vertical (so high In the standard gymnasium, there are few horizontal horse-tracking methods at home and abroad, instead of the usual parallelism. In the glare control of color TV broadcasting, it brings great difficulty to lighting design. The final effect of the design will not only directly affect the quality of color TV broadcasts, but also have a great impact on the future of international events in Ningbo. In the face of challenges, GP lighting designers actively communicate with research institutes and construction units, conduct on-the-spot investigations, on-site measurements, and then consider the actual environment of the site, through manual calculations and international professional illumination calculation software - AGI32 computer simulation calculations A rigorous argumentation was made, and finally a bold innovation based on effective data was obtained, using a light-belt type of cloth, which was placed close to the sides of the horizontal road. Ensure that all lighting indicators are up to standard within the scope of glare control, and experience through the National Construction Engineering Quality Supervision and Inspection Center, in line with training, competition, color TV broadcast requirements.
In the arrangement of the luminaires, it is necessary to meet the requirements of lighting and lighting, and to meet the architect's requirements for the overall landscape effect of the venue, but also to consider the convenience of installation and maintenance. Therefore, the horizontal horse of about 19 meters above the sports ground of the main stadium A total of 100 sets of 1000W floodlights (for home lighting), 16 sets of HIPO400 (for site cleaning), 32 sets of HIPO400 (for vertical upward film roofing), and 30 sets of TF300 (for emergency lighting, can be used on the road) Instant start).
In order to better control the glare, the lamp used in this project is equipped with a double-ended gold halogen light source, which can better control the generation of glare. The luminaire is equipped with an anti-glare grille, which is precisely controlled with a high-quality and precise reflector. The angle of the beam and the exact aiming point. The aiming point is determined from the following aspects: First, the utilization rate of light is high, most of the light is projected into the field; second, the site illumination is uniform; third, the adjacent beams overlap, and the different lighting modes can satisfy Illumination and illuminance uniformity requirements, even if there is a lamp damage, it will not affect the contrast and its uniformity. Finally, it is necessary to ensure that the glare generated by the athletes, referees, and viewers within the line of sight is minimized, reducing discomfort glare. The glare is limited by controlling the projection direction and projection angle of the luminaire. In addition, due to the use of a luminescent roof (32 sets of HIPO400 for vertical upward projection of the film roof), the background brightness is improved, and glare is effectively reduced.
8. Overview Design illuminance <br> Ningbo Beilun Arts Center held volleyball, basketball, handball, gymnastics and other events, venues accordance with the standards division, according to the design specifications to meet the requirements of various sports competitions. Lighting design indicators mainly include: horizontal illumination, vertical illumination, illumination uniformity, light source color temperature and color rendering index, glare index, shadow. These indicators directly affect the quality of the stadium's use, athletes' competition, sports venue lighting design must first determine the main technical indicators. Especially for the owners have color TV broadcast requirements. We refer to the latest field lighting design standards issued by the National Sports Commission, determine The main technical indicators of the site lighting. The following are the main technical indicators of the site lighting of each mode.
