[0002] Underwater fish attracting lights are suitable for various fishing environments, including but not limited to aquaculture, deep-sea fishing, night fishing in rivers and lakes, etc. Generally, underwater fish attracting lights have high power and large radiator size, and the main problems are as follows:

[0003] 1. The traditional approach is to consider the convenience of the structure, and usually the size of the lamp is made larger. The larger the size, the greater the water resistance, and the lamp is easily moved out of position by the water undercurrent;

[0004] 2. The waterproof structure of traditional lamps needs to be improved;

[0005] 3. Traditional underwater lamps, after being used for a period of time, are prone to water mist on the inner wall of the glass even if the lamps are not exposed to water. This is because the moisture in the air inside the lamps condenses on the inner surface of the glass.

[0006] Therefore, it is necessary to improve the existing underwater fish attracting lamp. Utility Model Content

[0009] Furthermore, a plurality of internal ribs with different heights are formed in the heat dissipation channel.

[0010] Furthermore, the elastic rubber ring includes a fluorine rubber ring and an O-type silicone ring.

[0011] Furthermore, a fluororubber ring is provided at the upper end of the radiator and the glass tube and embedded in the upper end cover, and a fluororubber ring is provided at the lower end of the radiator and the glass tube and embedded in the lower end cover; the O-type silicone ring is located in the closed cavity and wrapped around the outside of the radiator.

[0012] Furthermore, a handle is provided on the upper end cover, and a counterweight seat is provided below the lower end cover.

[0013] Furthermore, a gap is left between the lower end cover and the counterweight seat.

[0014] Furthermore, a bracket is arranged outside the glass tube, and the upper end cover and the lower end cover are fixed on the bracket.

[0015] Furthermore, the light source plate is arranged on the outer surface of the heat sink in a hexagonal shape.

[0016] Furthermore, the closed cavity is filled with nitrogen or an inert gas.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the underwater fish-attracting lamp provided by the utility model adopts a hollow profile radiator. After the water flows into the hollow heat dissipation channel and is heated, its density becomes lighter and rises, forming a "chimney effect" similar to that in the air, thereby reducing water resistance and achieving rapid heat exchange.
