LED underwater lights need to meet the special sealing structure and insulation strength required by DMX512 LED underwater lights. Due to the particularity of the LED underwater light application-it is an electrical product that works underwater, so it also has special requirements for its technical indicators. First of all, the protection level of LED underwater lights must reach IP68, including underwater cable joints. Only in this way can the LED underwater lamps be immersed in water for a long time without leaking. Secondly, after the LED underwater lamp is immersed in the water, it must be required that the insulation resistance between the external end of the cable and the lamp housing should be ≧2MΩ. The purpose is to ensure that the insulation strength of the lamps meets the basic technical requirements, to prevent the generation of leakage current, and to prevent the occurrence of safety accidents. In this way, the personal safety of personnel and the normal operation of LED lamps can be guaranteed.
