How to arrange the lamps and lanterns in the football field?
After the official use of the video referee, there are also new requirements for shooting and lighting of the game. Does anyone know the lighting design of the football field?
Lighting strip design of football field
The light strip design is another form of the left and right side layout, that is, the lighting system is designed in line on the left and right sides of the football field to produce a continuous light strip. The light strip lighting is evenly distributed, and the brightness of the football players and the football field is relatively good. Now the world believes that this lighting method can meet the needs of color TV broadcasting, high-definition TV broadcasting and even ultra-high-definition TV broadcasting.
The total length of the light strip needs to exceed the goal line by 10m. Compared with the first-grade and super football fields, the total length of the light strip is generally no less than 180m. The projection angle of the lighting fixture should not be less than 25°. Some football field light strip lighting is very close to the boundary line of the field (the angle is above 65°), and the side of the sports field closer to the light strip cannot get sufficient vertical illumination, so the rear lighting must be strengthened system.
Football field lighting standards
The International Football Federation FIFA promulgated a new version of the "Football Field" standard in 2011. The football field lighting has added a part that cannot be arranged with lighting fixtures to protect football players and referees to reduce the interference of glare.
First, take the center point of the boundary line as the core. When there is TV broadcast, the left and right sides of the boundary line are within 15° angles; when there is no TV broadcast, the left and right sides of the boundary line are within 10° angles.
Second, in the area behind the goal at 25° elevation in the center of the sports field.
Finally, based on the boundary line, the area enclosed by the 75° elevation angle outside the restricted area and the 20° angle of the outer extension line of the short side of the restricted area, but some designated areas are not counted. Naturally, lighting fixtures designed for comprehensive stadiums are not subject to this limitation, but these limited areas cannot be illuminated in football mode.
Generally speaking, the light belt design uses a variety of projectors with different beam angles for combined projection. The narrow beam is used for long-range projection, and the medium beam is used for close-range projection. The shortcomings of the optical ribbon design are: the level of glare needs to be adjusted is relatively high, and the physical feel of the east and the west is not good.
