Description

LED underwater light and manufacturing method thereof

With the increasing popularity of LED lights, LED underwater lights are installed for various occasions. For example, LED lights installed in the outer shell below the hull waterline can be used as landscape lights or fishing lights for fishing; The LED lights installed on the bottom or wall of the swimming pool provide a bright and beautiful sports environment for the night swimmers. The various colored LED lights on the bottom of the aquarium make the aquatic creatures more colorful.

LED lamps for the above purposes have a common feature, that is, the entire lamp is immersed in water for a long time, and some are located within a few meters of water, which requires the lamp to have better waterproof sealing performance. The existing LED underwater lights usually consist of a housing with an opening, an LED lamp set mounted in the housing, a glass disposed at the opening, a cover connecting the opening of the housing and pressing the glass, such LED water The downlight always has a space containing gas in the lamp body, that is, despite the conventional sealing technology, the entire LED underwater light can reach a certain depth under water, and the water cannot enter the LED water which is still a shell. The inside of the lamp is turned off, but after a long period of immersion, especially after seawater immersion, the rubber as a sealing material will age and cause the seal to fail. For example, LED underwater lights currently installed under the hull waterline usually lose their sealing function in a few months or a year, and there is a small amount of water seepage in the lamp housing. Moreover, the replacement of the LED underwater lights generally requires the hull to be discharged or docked. This requires LED underwater lights to remain sealed for a long time. In addition, the installation of the existing LED underwater lights is usually directly attached to the hull, the swimming pool wall and other installations, which is not the best design for LED underwater lights with high heat dissipation requirements.
