Because the optical fiber has the characteristics of hydrophilic, coupled with its photoelectric separation, so the use of water features in the lighting, you can easily create the effect of the designer, and on the other hand, it is also not the problem of electric shocks, can achieve security considerations. In addition, the application of the structure of the optical fiber itself, but also with the pool of each collocation, so that the optical fiber body has become a part of the water, which is not easy to achieve the effect of other lighting design. The lighting of the pool is also a popular SPA occasion, and the application of optical fiber is the best choice. Because this is a place of human activities, safety considerations are much higher than the above water tank or other indoor places, so the optical fiber itself is the photoelectric separation characteristics, and color of the color of the effect, and can meet the needs of this kind of place.
