Light is three (two)

Internal flare control

Due to the unique optical properties of the water medium, the control of the lighting of the natatorium is more difficult than other types of venues. The main methods include the following:

Controlling the glare of the water surface by controlling the projection angle of the lamp. In general, the stadium lighting projection angle is less than 60 degrees, the pool of light projection angle is required to be less than 50 degrees, the greater the incident angle of light, the more water reflected light.

Aiming at the control measures of the diver's glare. For diving, its range includes 2 meters from the platform, springboard to the surface of the water on the 5 meters, that is, the entire trajectory of diving athletes space. In this space, the venue lights are not allowed to have any uncomfortable glare athletes.

Strictly control the glare of the camera. That is, it is not allowed to reflect the light of the still water surface from the main camera, and the light emitted by the lamp can not be directly transferred to the fixed camera.

Controlling the glare of light in the water. For the television broadcast of the swimming diving hall, the game hall space is larger, the venue lighting lamps generally use a large power LED lamps.

Extension: underwater lighting solutions

Underwater lighting can use direct lighting lighting on the surface, but due to the absorption effect of the lighting effect of the water, in synchronized swimming and diving deep water in the swimming pool or shooting due underwater lighting. In order to avoid underwater lighting through the surface caused by glare, the incident light and the water surface should be greater than the critical angle of the angle, so that the light of the reflection in the water, which can illuminate the surface, even under water and not on the bright water produce glare.

Underwater lighting should be arranged in the side wall of the pool, the pool should be arranged in the two rows of lamps, a deeper row of lights in the underwater 3M, another row in the 13-110m, so that the water to meet the requirements of illumination. The lamp is arranged in the side wall of the pool wall. The utility model is a lamp niche with a waterproof glass which is arranged at the edge of the swimming pool. The wet type is waterproof, watertight type directly into the niche into the water immersion.
