The LED underwater light is small and exquisite in appearance, beautiful and generous, and its appearance is similar to some buried lights, but there is an additional installation chassis, which is fixed with screws. Because the LED underwater light is used under the water and needs to withstand a certain pressure, it is generally made of stainless steel, 8-10MM tempered glass, high-quality waterproof joint, silicone rubber sealing ring, curved multi-angle refraction tempered glass, waterproof, anti- Dust, anti-leakage, corrosion-resistant.
Scope of application of LED underwater lights: underwater lighting in large swimming pools, fountains, aquariums and other places.
Purchase Notes
Due to the particularity of the application of underwater lanterns, it is an electrical product that works underwater, so it also has special requirements for its technical indicators.
First, the protection indicators of underwater lanterns: the protection indicators of underwater lanterns are divided into two aspects: dustproof and waterproof. According to the IEC standard, the internationally used protective marking symbols are as follows:
1. Dustproof grade: According to the national standard, the dustproof grade of lamps is divided into 6 grades. Among them, level 6 is the highest, and the dustproof level of underwater lanterns should reach level 6, and its marking symbol is: IP6X.
2. Waterproof grade: According to the national standard, the waterproof grade of lamps is divided into 8 grades. The 6th grade is water splash type, the 7th grade of LED lamps is watertight type, and the 8th grade is pressurized watertight type. The eighth level is the highest, and the waterproof level of the underwater lantern should meet the requirements of level 8, and its marking symbol is IPX8.
Combining the above two requirements, the dustproof level of the underwater lantern is 6, the waterproof level is 8, and the marking symbol is: IP68.
Second, the anti-electric shock safety indicators: the national standard for the anti-electric shock indicators of lamps and lanterns is divided into four categories: namely O, I, II, III. At the same time, the national standard clearly stipulates that the underwater lighting fixtures in swimming pools, fountains, leisure pools and other similar places should be Class III lamps for protection against electric shock. The working voltage of its external and internal circuits should not exceed 12V.
Third, the rated working voltage: the rated working voltage of the lamp is the electrical parameter index of the lamp, which directly determines the use environment of the lamp, that is, the actual working voltage must be consistent with the rated working voltage. Otherwise, either because the voltage is too high and the light source is burned out, or because the voltage is too low, the lighting effect of the light cannot be achieved.
