"People-oriented" is the purpose of lighting. Stadium lighting is no exception. A healthy light environment is a must. In the lighting design of stadiums, glare and interference light are the primary unfavorable factors that affect athletes' competitive level, and they are also important factors that affect the quality of TV broadcast. Glare is an important indicator that affects light health and light environment. Glare refers to the visual conditions that cause visual discomfort and reduce the visibility of objects due to unsuitable brightness distribution or extreme brightness contrast in space or time in the visual field. There is a sense of light in the visual field that the human eye cannot adapt, which may cause disgust, discomfort or even loss of clarity. It also refers to the presence of excessively high brightness in a certain part of the field of view or excessive brightness changes before and after. Glare is one of the important causes of visual fatigue.
In indoor venue lighting, the sports lighting level is I. When the use function is fitness or amateur training, the glare value (GR) should not be greater than 35, and the glare value of other sports lighting levels should not be greater than 30; in outdoor venue lighting, the sports lighting level It is I, when the use function is fitness or amateur training, the glare value (GR) should not be greater than 55, and the glare value of other sports lighting levels should not be greater than 50. LED stadium lighting can reduce glare and spilled light through the following measures:
1. Professionally designed led light for LED characteristics, equipped with medium light distribution, narrow light distribution and extra narrow light distribution;
2. Scientific lens and reflector design to achieve effective control of light;
3. Make full use of the secondary reflection of the reflector to reduce direct glare;
4. Scientifically determine the working power of the LED light source to control its central light intensity;
5. Design a suitable external glare controller to reduce glare and use re-reflection to improve light efficiency;
6. Control the projection angle and direction of a single different LED led light bead.
