Description

Technical Field

[0001] This utility model relates to the field of lighting lens technology, and in particular to an underwater miniature lamp. Background Technology

[0002] In underwater applications such as landscape lighting, aquarium aquaculture, and pool decoration, traditional underwater lights commonly suffer from water ingress failure due to thermal expansion and contraction. Specifically, during operation, the heat generated by the LED light source and driver circuit raises the internal temperature of the lamp body to 60-80℃, causing linear expansion of materials such as the aluminum alloy shell and PC lampshade. After the lights are turned off, the drastic temperature difference between the ambient water and the lamp body causes rapid contraction. A single thermal cycle can cause permanent deformation of the seals. This deformation accumulates continuously under more than 10 thermal shocks per day, leading to an expansion of the sealing gaps and ultimately causing water vapor penetration, resulting in irreversible damage such as electrolytic corrosion of the circuit board and oxidation of solder joints, reducing the average lifespan of the lamp to less than one year.

An air chamber is hollow inside the reflector cover, and the air chamber contains inert gas. The reflector cup is embedded in the reflector cover. A slot extends upward from the bottom of the housing, and a series of reflectors are evenly distributed around the top of the housing and circumference of the reflector cover. The panel includes several brackets, with an aluminum substrate connected to the top of each bracket. A substrate is connected to the bottom center of the aluminum substrate, and an LED light is mounted on the substrate. The LED light is compatible with the LED mask. The panel includes an annularly arranged air chamber shell and a leak-proof base plate.
