Lighting device with hydroelectric generator for use in swimming pools, water fountains or spas

Abstract

The lighting device is designed to operate underwater without an external power source. It harnesses the kinetic energy of water flowing through supply, injection, suction, or drainage pipes in swimming pools, spas, or ornamental fountains. It also indicates the direction of water flow, warning of suction and preventing entrapment hazards. Additionally, it features a temperature sensor to alert users to potential temperature increases that could pose a health risk.
