Network information is difficult to distinguish true from false. But it is enough to awaken our vigilance on the safety of underwater electricity use. Is this bloody lesson telling us not to go swimming? of course not. Did you tell us not to use underwater lights in the swimming pool? No, because Chinese people are very busy during the day, and many people only have time to take their children to swim in the evening, etc. Underwater lights can provide good underwater lighting effects. In order to have a safer and better swimming environment, at the beginning It was invented and used, so not using underwater lights is not a real solution to the problem.
The accident has occurred, always find out the cause and find out the solution, starting from the cause of the accident, analyze the two possible causes of underwater lamp leakage: 1. unqualified installation specifications; 2. unqualified lighting specifications.
The reason for this is that LED underwater lights are widely used at present. The country has clear regulations for underwater lights to be used for landscape lighting. The voltage cannot exceed 24V, and the commonly used voltage is 12V. The voltage of 12V is not only within the range of human body, but also lower than There are many safety voltages (36V), so as long as it is a standard lamp, it is impossible to cause any problems. Therefore, the editor believes that there are only two possible reasons mentioned above.
Installation specifications for underwater lights:
(1) Before installation, take a sample to check whether the appearance of the LED underwater light is intact and whether the function (waterproof, lighting, wiring, etc.) is normal;
(2) Ensure that the installation position of the underwater light is fixed and will not be loosened due to water pressure;
(3) Connect the relevant cables of the underwater light to ensure that the working voltage of the conductor under water does not exceed 12V, and the transformer device is set in a safe and dry location on land;
(4) Seal all exposed conductors with waterproof glue;
(5) Regular inspections and maintenance are carried out.
Production specifications for underwater lights:
(1) Comply with the relevant parameters of the national regulations for the safe use of electricity for underwater lights;
(2) The waterproof and dustproof grade is IP68;
(3) Only after passing the relevant national qualification certification test can it be listed.
Therefore, it is believed that whether the regular LED underwater light will leak when placed underwater, the answer is that it may be, but it will definitely not cause death. The cause of the accident is still under investigation.
