The working principle of the LED faucet

LED illuminated faucet

With the continuous progress of society, people have higher and higher requirements for the quality of life. The LED light-emitting faucet can be used in the dark and can be used normally in the event of a power outage, which meets people's higher requirements for the quality of life, and is highly sought after by people in developed countries and economically developed regions.

The LED light-emitting faucet is loaded on the water pipe, the water pipe switch is turned on, and the water flow of a certain pressure passes through the LED light-emitting faucet, then the LED in the water faucet will emit light. Its working principle is: install a small hydro-generator in the water pipe, connect both ends of the lead wire to the circuit board, and solder LED lights on the circuit board. When water flows through the water pipe, the water flow will drive the impeller to rotate. When the water flow reaches a certain pressure and the speed of the impeller reaches a certain number of revolutions, the current and voltage generated by the generator will drive the LED lights on the circuit board to emit light.

It is not difficult to find out by analyzing the working principle of the existing LED light-emitting faucet: along with the constant increase of the water flow pressure, the impeller rotational speed also constantly increases, then the generator will produce a very large current and voltage, and the LED lamp has the possibility of being burned out, The generator itself can also be damaged by generating excessive heat. At the same time, the brightness of the LED lights in the existing LED light-emitting faucet device is greatly affected by the water flow and water pressure. When the water flow and water pressure are relatively small, the LED light brightness will be weaker, and when the water flow and water pressure are relatively large, the LED light brightness will be relatively high. If it is strong, it may even appear that the entire LED light-emitting faucet device is damaged and does not emit light, which affects the normal use of the faucet.

Moreover, due to the difference of the water flow pressure, the brightness of the LED lamp is also changed along with the change, and the stability is poor, and sometimes even the situation that the LED lamp flickers on and off, affects the use effect.
