Precautions for underwater light installation:
1. First of all, for the selection of lamps, pay attention to the waterproofness of the lamps, the power supply voltage, and the power consumption of a single lamp;
2. Involving low-voltage and high-current power supply will affect the voltage drop of the line, the voltage drop at the end of each line must be calculated first, and redundancy should be reserved in advance;
3. The isolation transformer and leakage switch that supply power to underwater lights must be arranged outside the water area to avoid electric shock accidents;
4. Whether it is surface installation or concealed installation, a 1-2 meter long cable should be reserved, so as to avoid problems in the future when the lamps and lanterns go wrong, the lamps can be lifted to the water surface to replace the wiring and wiring for waterproof treatment;
5. As for other wiring, the wiring joints are made waterproof, and general plumbers and decorators can basically handle it! the
6. The LED underwater light should be powered by a DC constant current power supply. Under the control of a constant current power supply, the forward voltage drop of the underwater light will become smaller as the temperature of the LED chip increases, which does not have much impact on the underwater light. But if it is driven by a constant voltage, the current of the chip of the underwater light will continue to increase as the temperature rises. In severe cases, the underwater light may even be burned.
7. Anti-static measures need to be taken. Underwater lighting products must adopt certain anti-static measures during the process of processing, production and installation, such as: the workbench must be grounded, workers must wear anti-static clothing, anti-static rings, and anti-static gloves, etc., can be installed if conditions permit Anti-static ion fan, at the same time, it is necessary to ensure that the air humidity is about 65% during installation, so as to avoid static electricity caused by too dry air. In addition, LEDs of different quality grades have different antistatic capabilities, and LED underwater lights with higher quality grades have stronger antistatic capabilities.
8. Pay attention to the sealing of LED products. No matter what kind of LED lighting products, as long as they are used outdoors, they will face the problem of moisture-proof and sealing, especially for LED underwater lights. If the sealing problem is not handled well, it will directly affect the service life of the product.
