Artificial light and natural light should be avoided to cause glare to athletes, referees, cameras and spectators. The reflection ratio of the wall and the roof is not lower than that of the 0.4-0.6. should be guaranteed to surround the swimming pool with enough vertical illumination. Indoor swimming pool usually consider the maintenance of lamps and lanterns, generally do not decorate the water above the surface, but the water above the special repair channel except.
For venues that do not have a televised request, lamps are often scattered arranged in the top of the water outside the ceiling, under the roof or wall, for television broadcast requirements of the venues, lamps are generally used light belt layout, that is, in both sides of the pool on the Shore Layout Longitudinal ma Dao, at both ends of the pool on the shore layout transverse ma. In addition, it is necessary to set the appropriate lighting in the platform and springboard to eliminate the shadow of the platform and Springboard, and to focus on the diving swimming pool lighting fixtures. It should be stressed that diving items should not be placed above the diving pool lighting.
Otherwise, the water will appear in the mirror image of the light, the athletes have light interference, affect the athlete’s judgment and play. Glare control due to the unique optical characteristics of water medium, the glare control of Natatorium site illumination is more difficult than other types of venues, it also appears to be important for dragons. Control the reflective glare of the water surface by controlling the projection angle of the lamp. Generally speaking, the lighting projection angle of the gymnasium is not larger than the lighting projection angle of the 60° swimming hall, the requirement is not greater than 55°.
The greater the angle of incidence of the 50° light, the more reflective light on the surface. Glare control measures for diving athletes. For diving, the range includes 2 meters from the platform, and a springboard of 5 meters to the surface. The whole trajectory space of the diving athlete. In this space, the indoor swimming pool lighting fixtures of the venue is not allowed to have any discomfort glare to the athlete. Strictly control the glare of the camera. That is, the light from the static water surface should not be reflected to the main camera vision, and the light emitted by the luminaire shall not be directed to the fixed camera. It is preferable to not directly illuminate a fan area centered on a fixed camera.
