How to design outdoor football field lighting?
For the sport of football, the visual effect of the special lights on the football field is extremely critical. In the lighting effects of special lights for football fields, football is an object without light. When taxiing and landing in mid-air, there are several reflective surfaces compared to football players. One is: towards the top of the sky, the second is: towards the bottom of the ground, and the last is: towards the surroundings. The vertical plane.
The top, bottom, and vertical surfaces of the football reflect light energy in the visual organs of the human eye. In the visual perception system, different levels of visual effects are formed. Brightness and color perception, forming objects Three-dimensional visual effect space.
In the football field, most of the light energy received on the football is the direct radiation of the football field lighting effect. Most of the light energy received under the football comes from the diffuse reflected light on the ground of the football field. Most of the light energy received by the vertical surface of the football is the light of the vertical illuminance in the football field lighting effect.
The light energy on these reflective surfaces of the football must be higher than the corresponding illuminance value, and it must also have a scientific and standardized distribution ratio. Only objects that slide in the sky can form a clear sense of brightness in the visual perception system of human eyes, and form a three-dimensional sense of real object visual effects.
From this, it is known that if a special lamp for a football field is to be made, the actual effect of the lighting effect of the stadium lighting has a good three-dimensional visual effect. The lighting effect of the stadium must not only have a higher horizontal illuminance value on the ground, but also a corresponding vertical illuminance value. Especially the scientifically standardized ratio of horizontal illuminance to vertical illuminance is very important.
