Due to the special nature of the occasion LED underwater lights application is working underwater electrical products, so there are special requirements for its technical specifications.
First, the protective indicator LED underwater lights: Protective index points LED underwater lights both dust and water, IEC standard requirements, internationally accepted symbol of protection marked as follows:
1, Dust Proof levels: the national standard, dustproof luminaires rating 6. Which is the highest level 6, LED underwater lights dust levels should reach 6 which marked symbol: IP6X.
2, Waterproof grade: GB provisions, lamps waterproof rating 8. Its level 6 water splash type, led lighting the first seven watertight type, the first eight of pressurized watertight. Eighth grade is the highest, LED underwater lights waterproof rating should reach 8 requirements, which marked symbol IPX8.
Taking these two aspects of the requirements, LED underwater lights dustproof grade 6, waterproof rating of 8, which marked symbol: IP68.
Second, electric shock safety indicators: GB of electric shock indicator lamps are divided into four categories: namely O, Class I, II, III,. At the same time, clearly defined national standard for swimming pool, fountain, paddling pool and other similar places underwater lighting, should shock protection Class III lamps. Its external and internal lines operating voltage should not exceed 12V.
Third, rated voltage: the rated working voltage lighting fixtures electrical parameters are indicators, which directly determines the lamp's environment, that is the actual working voltage must be consistent with the rated voltage. Otherwise, not because the voltage is too high and burn the light source is too low and can not be achieved due to the lighting effect of the light.
