What are the standards for outdoor lighting?

1. The lighting of sports venues shall meet the use requirements of athletes, referees, spectators and other personnel. If there is television relay, it shall meet the lighting requirements of television relay.

2. When the major international competitions are broadcasted on high-definition television, the sports lighting should still meet the technical requirements of international sports organizations and institutions.

3. The lighting design of major competition venues shall consider the special functional lighting requirements during the games.

4. The lighting of sports venues shall include the lighting of competition venues, auditorium lighting and emergency lighting.

5. At the stage of sports building scheme design, the requirements of lighting design scheme should be considered at the same time.

6. The lighting design of sports venues should implement energy conservation while meeting the corresponding lighting indicators.

7. After the installation of the lighting system in the sports venues and before major competitions, lighting detection shall be carried out.

According to these 7 points, the outdoor lighting standard of the stadium will have a direction! Therefore, outdoor lighting court lighting should pay attention to the following:

1. The calculated maintenance coefficient of outdoor lighting court lighting should be 0.8; The maintenance coefficient of outdoor stadiums in foggy and heavily polluted areas can be taken as 0.7.

2. The ratio of the minimum vertical illuminance to the maximum vertical illuminance in four directions at each calculation point in the competition venue shall not be less than 0.3; It shall not be less than 0.6 when HDTV broadcasts major competitions.

3. The average vertical illuminance of the 12 rows in front of the auditorium and the rostrum facing the field direction with TV broadcasting requirements shall not be less than 10% of the average vertical illuminance of the main camera in the field. The average horizontal illuminance of the rostrum should not be less than 200lx, and the minimum horizontal illuminance of the auditorium should not be less than 50lx.

4. When LED sports lighting lamps are selected, the color tolerance of similar light sources shall not be greater than 5 SDCM.

5. The protection grade of the outdoor lamp shell shall not be lower than IP55, and the protection grade of the outdoor lamp shell shall not be lower than IP65 in places where maintenance is inconvenient or pollution is serious.

6. Light weight, small volume and small wind load coefficient should be selected for lamps installed in high altitude.

7. Lamps shall be equipped with or attached with angle adjustment indicating devices. The lamp locking device shall be able to bear the maximum wind load under the service conditions.

8. Outdoor lighting court lighting should be arranged on both sides, at four corners and in a mixed way.

9. With regard to super slow shot playback, GAISF, FIFA and OBS have all stipulated the vertical illuminance for slow shot playback and super slow shot playback, which is required to be no less than 1800lx, or even about 20001x.

10. In practical applications, stroboscopic lighting is particularly important for stadium lighting. When a relay game requires slow or ultra slow motion playback, the picture is prone to jitter. Therefore, the London Olympic Games has classified the stroboscopic transmission of sports television: the maximum stroboscopic transmission less than 1% is no stroboscopic transmission; Less than 6% is slight stroboscopic; Less than 10% is acceptable; More than 10% is intolerable. In many competitions, the stroboscopic ratio is usually less than 6%.

1. The on-site color rendering index and color temperature shall be the arithmetic mean of the measured values at each measuring point. The deviation between the on-site color temperature and the rated color temperature of the light source should not be greater than 10%, and the on-site color rendering index should not be less than 10% of the rated color rendering index of the light source.

12. Outdoor sports facilities are generally required to be 4000K or higher, especially in the evening when they are well matched with sunlight, and indoor sports facilities are generally required to be 4500K or lower. From the actual use and subjective evaluation, people will feel very uncomfortable when the color temperature is greater than 6000K.
