[0002] In the prior art, the heat dissipation components and light source of aquarium lights are set in a relatively enclosed outer shell. A heat dissipation grid is set at the rear end of the outer shell, and the heat absorbed by the heat sink is discharged from the lamp body by a cooling fan. However, due to the outer shell, the air inlet area and air volume are limited, which makes it impossible for the cooling fan to quickly and efficiently discharge the heat from the heat sink.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] The present invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0037] like Figure 1-6 As shown, a high-efficiency heat dissipation type shellless aquarium light includes a light source 1, a lens assembly 2 and a heat dissipation assembly 3 arranged coaxially. The heat dissipation assembly 3 includes a radiator 4 and a heat dissipation fan 5. A cavity 10 is formed on one side surface of the radiator 4. The light source 1 is disposed in the cavity 10. The heat dissipation fan 5 is located on the side of the radiator 4 away from the cavity 10.

[0038] The lens assembly 2 is connected to the heat sink 4, so that the light source 1 is sealed in the cavity 10; the outer circumferential side of the heat sink 4 is exposed to the outside.

[0039] In this embodiment, the aquarium light adopts a shell-less structure design. The exposed outer circumferential side of the radiator 4 forms an air inlet 40, thereby increasing the air intake by increasing the area and angle of the air inlet 40. Under the action of the cooling fan 5, the cold air carries the heat of the radiator 4 out from the air inlet 40 in 360°, thereby achieving efficient and rapid heat dissipation.

[0040] In addition, in this embodiment, the exposed outer circumferential side of the radiator 4 can also locally perform active heat dissipation, so that part of the heat absorbed by the radiator 4 is discharged through the cooling fan 5, and the other part of the heat is discharged through heat exchange with the external environment through the exposed local outer circumferential side, forming a highly efficient heat dissipation method that combines active and passive heat dissipation.

[0041] In addition, in this embodiment, the light source 1 is sealed within the cavity 10 between the lens assembly 2 and the heat sink 4, which is simple in structure, reasonable in design, and sealed and dustproof.

[0042] Furthermore, such as Figure 2 , 5 As shown in Figures 6 and 7, the radiator 4 includes a radiator body 41, and the outer circumferential side of the radiator body 41 is provided with a plurality of heat dissipation fins 42 distributed circumferentially around the axis of the radiator body 41.

[0043] A heat dissipation air duct 2020 is formed between adjacent heat dissipation fins 42, and a circular air inlet end face 30 is formed at the end of the plurality of heat dissipation fins 42 away from the heat sink body 41; the lens assembly 2 is connected to the heat sink 4 through the air inlet end face 30.

[0044] In this embodiment, when the cooling fan 5 is working, cold air enters the cooling duct 20 from multiple air inlets 40 distributed circumferentially on the air inlet end face 30 from different directions. Then, it absorbs the heat on the cooling fins 42 to form hot air that is discharged. Compared with the prior art, the cold air enters the cooling duct 20 from multiple directions in 360 degrees, which greatly increases the air intake and achieves efficient heat dissipation.

[0045] Furthermore, such as Figure 3 , 4 As shown in Figure 5, the middle part of the air inlet end face 30 is the air inlet area 302, and the side near the lens assembly 2 is the first connection area 301. The first connection area 301 is provided with a first external thread 1a, and the lens assembly 2 is threadedly connected to the heat sink 4 through the first external thread 1a.

[0046] In this embodiment, the lens assembly 2 is directly threaded to the heat sink 4 through the first connection area 301 of the air inlet end face 30. This not only provides good heat dissipation and stable and reliable connection, but also saves on housing components, reduces costs, and ensures the sealing of the cavity 10.

[0047] Furthermore, such as Figure 2 , 3 As shown, the lens assembly 2 includes a lens cap 21, a reflector 22, and a convex lens 23 arranged sequentially.

[0048] The convex lens 23 is disposed in the cavity 10 and covers the light source 1. The reflector 22 is sleeved on the side of the convex lens 23 away from the light source 1. The lens cover 21 is provided with a first internal thread 1b that mates with the first external thread 1a. After the lens cover 21 is threadedly connected to the first connection area 301, the reflector 22 and the convex lens 23 are fixed between the lens cover 21 and the heat sink 4.

[0049] The lens cap 21 can be rotated and adjusted relative to the first connection area 301.

[0050] In this embodiment, the lens cap 21 is threadedly connected to the first connection area 301 of the heat sink 4, which fixes the convex lens 23 and the reflector 22 in the light emission direction of the light source 1. This not only makes the installation and connection convenient and reliable, but also saves on the outer shell and improves the heat dissipation effect.

[0051] In this embodiment, the lens cap 21 can be rotated 360 degrees with the heat sink 4.

[0052] In this embodiment, the lens cap 21 is directly threaded to the first connection area 301, eliminating the inconvenience of fixing with screws and making assembly and disassembly more convenient.

[0053] In this embodiment, the outer diameter of the lens cover 21 is the same as the outer diameter of the air inlet area 302, ensuring the aesthetic appearance of the aquarium light.

[0054] Furthermore, such as Figure 2 , 3 As shown, a sealing element 6 is provided at the connection between the convex lens 23 and the concave cavity 10.

[0055] In this embodiment, the sealing of the cavity between the convex lens 23 and the light source 1 is ensured by the setting of the sealing element 6, thereby improving the dustproof effect.

[0056] Furthermore, such as Figure 2 , 3 As shown in Figures 4, 5, and 6, a second connection area 303 is provided on the side of the air inlet end face 30 away from the first connection area 301;

[0057] The heat sink 4 is provided with a wind collector 7 and a cover plate 8 on the side away from the lens assembly 2. The wind collector 7 is connected to the heat sink 4 through the second connection area 303. The cover plate 8 is connected to the side of the wind collector 7 away from the heat sink 4. An exhaust hole 81 is provided on the cover plate 8.

[0058] A bracket 60 is provided on the side of the cover plate 8 away from the air collecting hood 7; a mounting groove 601 is provided at the end of the bracket 60 that is connected to the cover plate 8; a first locking member 50 is provided in the middle of the cover plate 8; the first locking member 50 passes through the mounting groove 601 and is threadedly connected to the cover plate 8.

[0059] The bracket 60 is non-linear, and a slot 602 is provided at the end of the bracket 60 away from the cover plate. A second locking member 70 is provided on the slot 602. In this embodiment, the cooling fan 5 is protected by the air collecting shroud 7 and the cover plate 8. The air collecting shroud 7 concentrates the hot air formed after the heat is absorbed by each cooling air duct 20 onto the cooling fan 5, so that the hot air passes through the cooling fan 5 and is discharged, thereby improving the hot air discharge efficiency.

[0060] In this embodiment, the aquarium light and the bracket are adjusted and fixed along the mounting groove by adjusting the first locking member 50, and the bracket 60 and the aquarium light can be fixed on the aquarium by adjusting the second locking member 70.

[0061] Furthermore, such as Figure 4 , 5 As shown, the second connection area 303 is provided with a second external thread 2a, and the connection between the air collecting hood 7 and the second connection area 303 is provided with a second internal thread 2b.

[0062] In this embodiment, the air collector shroud 7 is directly threaded to the second connection area 303, eliminating the inconvenience of fixing with screws and making assembly and disassembly more convenient.

[0063] Furthermore, such as Figure 6 As shown, the heat dissipation fin 42 includes a first straight heat dissipation section 421 and a second U-shaped heat dissipation section 422. One end of the first straight heat dissipation section 421 is connected to the heat sink body 41, and the other end is connected to the U-shaped bottom of the second U-shaped heat dissipation section 422. The open ends of the multiple circumferentially distributed second U-shaped heat dissipation sections 422 form the air inlet end face 30.

[0064] In this embodiment, the heat dissipation area is increased by using a second U-shaped heat dissipation section 422, thereby improving the heat dissipation efficiency.

[0065] Furthermore, such as Figure 1 As shown, the outer diameter of the air collecting shroud 7 is the same as the outer diameter of the radiator 4.

[0066] In this embodiment, the aesthetic appearance of the aquarium light is ensured.

[0067] Furthermore, such as Figure 1 , 2 As shown, it includes a power cord assembly 9; the power cord assembly 9 includes a first power connection line 91 electrically connected to the light source 1 and the cooling fan 5, and a second power connection line 92 electrically connected to the power supply.

[0068] The first power connection line 91 and the second power connection line 92 are respectively provided with a male plug and a female plug at the connection point.

[0069] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
