The standard swimming pool of the official swimming pool is 50m long. The standard short pool is 25m long and 25m wide. There are 9 lanes to form 8 lanes. The width of each lane is 2.5m. The special, Class A and Class B swimming pools are 2.0m deep, and the Class C swimming pools are 1.3m deep. The depth of the diving pool is 5.25m.
The biggest problem with swimming pool lighting is how to control the light curtain reflection on the water surface.
The design of the swimming pool lighting and the installation of the luminaires should ensure that there is no visual interference and that the best results of the game are guaranteed. On the water surface of the swimming pool, the ratio of light reflection and transmission depends on the angle of incidence of the light.
In the lighting design of the swimming pool, special attention should be paid to the live broadcast of the color TV. In order to ensure vivid and clear images and vivid colors, it is necessary to pay attention to the installation position and projection direction of the lighting fixtures in order to meet the lighting standards and lighting quality requirements.
Basic lighting requirements
The lighting in the swimming pool is designed to meet the following requirements:
1. The minimum level of illumination at any point in the swimming pool should not be lower than 250lx;
2. The light should be able to refract into the water;
3. Avoid direct or reflected light to produce glare.
1. Water reflection
(a) still water surface
(b) fluctuating water surface
Figure 1 Reflectance of light reflecting through walls, ceilings, and water surface
As shown in Fig. 1, when light passes through the ceiling, the wall surface, and the water surface, Fig. 1(a) shows the light reflection on the stationary water surface, and Fig. 1(b) shows the reflected light generated when the water surface fluctuates.
The audience has a relatively high viewing angle in the stands. The typical viewing position is athletes, referees, staff, waiters or lifeguards standing by the pool. As shown in Figure 2, they have a lower angle of view, so their angle of incidence is generally larger. , thus having a higher reflectivity.

Solar Street Lights are raised light sources which are controlled by solar powered boards commonly mounted on the lighting structure or coordinated into the shaft itself. The sunlight based boards charge a battery-powered battery, which controls a fluorescent or LED light during the night. There are two types of solar light generally in the lighting market which called all in on solar street light and split solar street light.
Features of solar street lights: A modern solar street light has embedded solar panel, inbuilt lithium-ion batteries, battery management system, night and motion sensors as well as automatic controls. The fully automatic device comes with LEDs, inbuilt and replaceable Lithium-ion battery and passive infrared (PIR) sensors. A typical solar street light is weather-proof and water-resistant, has low insect attraction rate and low glare and has a longer life.
Advantages of solar street light:
Environmental protection: solar energy is green, clean and renewable energy. And the widely using of the solar lights can low down the emmision of the carbon dioside.
Cost less to save money: Since the solar lights can be 100% energy, zero electric bill will be paid after the customers install the solar lights. And customers can also save the cost in wire trench.
More easy installation: Does not like electric lights, there is no need wire trench for solar light installation. Everyone can install the solar lights in a very shorten time.
more safe: Solar lights is DC low voltage compared to dangerous 110-220V AC electric power, it does not harm to human.
