Description

Technical Field

[0001] This utility model relates to the field of aquarium lighting equipment technology, and is particularly suitable for LED lights in aquarium environments, solving the problems of low heat dissipation efficiency and waterproof safety in high humidity environments. Background Technology

[0002] Existing aquarium lights, such as CN 221763493 U, use natural heat dissipation through perforations on the heat sink surface. This method results in a long heat dissipation path, low efficiency, and light decay due to high temperatures over long-term use. Furthermore, the waterproof design relies on simple sealing rings, making it prone to water leakage in humid environments. This invention optimizes the heat dissipation path and enhances protection through an integrated heat dissipation structure and forced air cooling design. Summary of the Invention

[0003] To overcome the shortcomings of traditional aquarium lights, which rely on natural convection, have low heat dissipation efficiency, simple sealing structures, and are prone to component damage in high-humidity environments, the designer has actively researched and innovated to create a highly efficient heat dissipation aquarium light, making it more industrially valuable. This utility model achieves the above objectives through the following technical solution:

[0004] A high-efficiency heat dissipation aquarium light is characterized in that, from bottom to top, it comprises: a fixing ring 1, a reflector cup 2, a lens 3, a fixing bracket with a light source socket 4, a light source 5, a heat sink 6, a cooling fan 7, and a circular end cap 8.

[0005] As a further measure, the heat sink 6 has radially extending heat dissipation fins 601 and a light source mounting base 604 integrally formed inside;

[0006] As a further measure, the radiator is integrally provided with a first annular mounting groove 602 and a second annular mounting groove 603 at both ends;

[0007] As a further measure, the fixing ring 1 is screwed into the first annular mounting groove 602, and the gap between the outer diameter of the fixing ring 1 and the inner wall of the radiator 6 forms an air inlet 9 for heat dissipation.

[0008] As a further measure, the circular end cap 8 is fixed to the radiator 6 by the mounting post 605, and its diameter is smaller than the outer diameter of the radiator 6. The gap between the circular end cap 8 and the radiator 6 forms the air outlet 10 for heat dissipation.

[0009] As a further measure, the heat dissipation fins 601 are provided with mounting posts 605; the height of the mounting posts 605 is greater than the depth of the second annular mounting groove 603, and is used to fix the heat dissipation fan 7 and the end cover 8.

[0010] As a further measure, the light source mounting base 604 is provided with screw holes, the light source 5 is attached to it by thermally conductive adhesive, and is pressed and fixed by the fixing bracket 4;

[0011] As a further measure, the heat dissipation air inlet 9 and the heat dissipation air outlet 10 form a straight-through air duct, and the airflow flows in a straight line through the heat dissipation fins 601;

[0012] As a further measure, the fixing ring 1, end cap 8, reflector cup 2 and lens 3 form a sealed protective layer to prevent water vapor from entering.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the gap between the fixing ring 1 and the heat sink 6 forms the air inlet 9, and the gap between the end cover 8 and the heat sink forms the air outlet 10. With the help of the cooling fan 7, the airflow is driven to pass straight through the heat sink fins 601, shortening the heat dissipation path and improving the heat dissipation efficiency; the integrated heat dissipation structure: the heat sink fins 601, the light source mounting base 604 and the mounting groove (602 / 603) are integrally cast, which improves the heat conduction efficiency; the fixing ring 1 presses the lens 3 and the reflector cup 2, and the end cover 8 seals the heat sink, forming a physical water barrier, which is suitable for the high humidity environment of aquariums; modular assembly reduces maintenance costs.
