First of all, the most important but often overlooked problem is that when designing the pool lighting, the lighting of the surrounding environment is not considered, but only the design of the swimming pool itself.
Why should we consider the whole? One reason is that the brightness in the pool should match the brightness of the surrounding environment. This is also a safety factor. For example, lifeguards often complain that the ceiling light reflects on the water surface and cause a lot of glare.
We need to keep in mind the three important functions of pool lighting: illuminating the floor and sidewalls of the pool, illuminating the swimmers and objects in the water, and illuminating the water itself to produce certain glare effects. The realization of the last one requires small particles or bubbles in the water to be emitted by the inground pool light.
The second important factor is that the lighting design of the pool should be considered early in the pool design phase.
When the concrete in the pool is poured and the embedded parts of the luminaire are not placed, it is very difficult to drill holes in the concrete.
It is not recommended to have a surface-mounted swimming pool led light in a public swimming pool because it is easily damaged.
Repairing the pool fixtures is cumbersome, so you need to use good quality fixtures and long-life light sources, not to mention the IP rating must be 68.
In addition to the above two points, what else should I pay attention to?
1. Installation depth
Depending on the depth of the pool and the beam angle of the luminaire: the installation depth of the general swimming pool is usually 600-700mm. The children's pool is 400-500mm.
Remember that only when the incident angle of light hitting the water-air interface is less than 41 degrees will it be reflected back to the surface. As if the installation depth is too shallow, the object light shine water (e.g. swimmer) to escape before the water went to the air, looking down from the water below the lamp will be a great dark area. If the installation is too deep, you will see a glaring highlight below the luminaire. When the swimmer is close to the luminaire, the lighting will not be enough.
2. Lighting light distribution
When considering the problem of light distribution, we need to think about whether we need more uniform illumination or some kind of accent lighting, or both.
Most underwater lights have different light beams from 10 to 90 degrees, and some have " Multiflux " multiple light distribution methods, such as a 120-degree beam angle but a 30 degree narrow light in the center. For shallow pools below 1.5 m, an ellipsoidal light distribution, such as 15 x 40 degrees, is recommended to avoid glare and light loss.
3. Dimming control
Pool lighting rarely requires dimming unless the same fixture is used in all places. However, in some places, 100% brightness is not required. Whether dimming is required or not is a consideration when designing and selecting a luminaire.
But many times the pool needs to be able to RGB or RGBW color, this time you need a good controller, such as DMX control. If you want both a good color effect, but also very positive white light, then it would use RGBW of LED lamps, so as to individually controlled LED red, green, blue and white production.
For most of the pool lighting, users like to have only one controller, which has several static or dynamic scenes set, each of which can be individually controlled and adjusted. In other cases, the scene of the pool is set with the lighting scene of the surrounding environment.
4. Processing elements other water
Many times there are other water elements in the design of the pool, such as falling water, fountains or water spray. Don't forget to add effect lighting to them, such as lighting from below the pool or behind them.
5. To handle special needs swimming pool
Finally, there are some special pool needs that may need to be considered. For example: small decorative LED points, movable floor, flush surface installation or embedded installation requiring thin doughnuts, when the pool is high, the lamps need 1.4539 stainless steel alloy body to prevent corrosion, or sometimes it may be necessary to replace the existing 1-day luminaire with a new LED luminaire.
