Why underwater lights don't light up when powered on and how to troubleshoot the cause?
Many engineering companies fail to light up or burn out the light source at the beginning of installation, which may be caused by various reasons such as power supply, transformer, power supply voltage, and waterproof issues. When troubleshooting and solving problems, investigate them one by one and take corresponding measures to handle them.
Firstly, consider whether AC and DC power sources are correct? Although many swimming pool underwater lights are 12V, there are also differences in the power sources they use. One type uses AC power, while the other uses DC power. It is necessary to
Make the difference and use the correct power supply.
The second step is to inspect the transformer. The working voltage of underwater swimming pool lights is generally 12V or 24V, while the mains voltage is 220V, so it is necessary to use a suitable transformer to reduce voltage. If it is directly plugged in or used incorrectly
Transformers can cause the pool lights to burn out and not light up directly.
Check the power supply voltage in the third row. When supplying power to the underwater lights in the swimming pool, it is necessary to ensure that the voltage of the lights remains greater than or equal to 11V. In addition, if the lamp is too far away from the transformer, it will cause the voltage at both ends of the lamp to be much lower than 12V, although the light is good, it cannot reach a certain voltage and the light will not light up normally. In this case, it is possible to consider increasing the power of the transformer or adjusting the path size of the main line.
Check the fourth row for water leakage and water ingress in the lighting fixtures and wiring outlets. The underwater lights in the swimming pool must meet the international highest waterproof IP68 level. Some unlicensed and unqualified lights are prone to leakage and water ingress, resulting in the lights not being able to light up; In addition, if the waterproofing of the underwater lights in the swimming pool is not satisfactory, and the wiring between the lights and the main line is clearly flooded, it can also cause damage to the lights and prevent them from turning on. Therefore, during the construction process, it is necessary to do a good job in waterproofing, such as using waterproof junction boxes, sealants, etc.
