Description

Technical Field

[0001] This utility model relates to the field of downlight technology, and in particular to a high-power downlight. Background Technology

[0002] As people's pursuit of quality of life continues to improve, downlights, as a common lighting device, are widely used in various indoor and outdoor lighting scenarios, such as for ambient lighting or supplemental lighting for fish tanks, making them more aesthetically pleasing.

[0003] Downlights, due to the limitations of their usage scenarios, need to be small and aesthetically pleasing. Therefore, their internal structure is relatively compact. As a result, considering heat dissipation issues, their power is generally not high, usually only 30-50W. If the power is higher, the lifespan will be affected due to heat dissipation problems.

[0004] Therefore, the reason why existing downlights do not have enough power is that the internal heat cannot be dissipated quickly.

[0005] In view of this, a high-power downlight is proposed. Utility Model Content

[0006] The purpose of this invention is to solve the technical problem that existing downlights have insufficient power because the internal heat cannot be dissipated quickly, and to propose a high-power downlight.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A high-power downlight includes a housing with heat dissipation fins arranged circumferentially on the sidewalls of the housing; a heat dissipation channel is provided between any two sets of heat dissipation fins; a light bulb and a fan are installed inside the housing, with the fan located above the light bulb; the bottom of the light bulb and the top of the fan are interconnected through the heat dissipation channel.

[0008] Preferably, the housing has a first mounting area and a second mounting area; the fan is mounted in the first mounting area; and the light is mounted in the second mounting area.

[0009] Preferably, the inner wall of the outer casing is provided with a bottom groove, a middle groove, and an upper groove; the light source is located between the bottom groove and the middle groove; and the fan is located between the middle groove and the upper groove.

[0010] Preferably, the bottom of the first mounting area is provided with an inner protruding strip.

[0011] Preferably, it further includes a convex mirror and a bottom shell; the convex mirror is located in the bottom groove; the bottom shell is threaded to the bottom of the outer shell and abuts against the convex mirror.

[0012] Preferably, the top sidewall of the convex mirror is covered with a protective ring.

[0013] Preferably, a gasket is provided between the bottom shell and the convex mirror.

[0014] Preferably, the top of the bottom shell is provided with a first slot, and the outer wall of the first slot is provided with an upper protrusion; the bottom of the outer shell is provided with a second slot.

[0015] Preferably, a protective plate is fixedly installed at the bottom of the light-emitting lamp.

[0016] Preferably, a top shell is threadedly connected to the top of the outer casing, and a mounting rod is fixedly connected to the top shell.

[0017] Compared with the prior art, this utility model provides a quick-change printing platform for 3D printing, which has the following advantages: 1. This high-power downlight, through the design of the heat dissipation channel, works in conjunction with the fan to efficiently and quickly dissipate heat from the light source, thereby maximizing the power of the light source within a limited space, reaching 100-130W. 2. This high-power downlight features a bottom groove, a middle groove, and an upper groove design, which causes both the top and bottom ends of the first and second mounting areas to be recessed inward.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Example: like Figures 1-8 A high-power downlight includes a housing 1, with heat dissipation fins 101 arranged circumferentially on the side wall of the housing 1. The number of heat dissipation fins 101 is between 30 and 60. Both the housing 1 and the heat dissipation fins 101 are made of metal, such as aluminum alloy, to facilitate heat conduction. There is a heat dissipation channel 102 between any two sets of heat dissipation fins 101, which is the gap between the two sets of heat dissipation fins 101.

[0023] The housing 1 contains a light lamp 4 and a fan 7. The fan 7 is located above the light lamp 4, and the bottom of the light lamp 4 has an integrated LED light bead 401.

[0024] The bottom of the light lamp 4 and the top of the fan 7 are interconnected through the heat dissipation channel 102. That is to say, through the heat dissipation channel 102, the space from the bottom of the light lamp 4 to the space between the light lamp 4 and the fan 7, and to the space at the top of the fan 7 are all connected, and airflow can flow between them.

[0025] During operation, while the heat dissipation fins 101 dissipate heat, the fan 7 also starts and blows air downwards. In other words, the fan 7 quickly removes the heat from the LED 4 through the heat dissipation channel 102. At the same time, the airflow also enters the bottom of the LED 4 through the heat dissipation channel 102, and the heat at the bottom of the LED 4 is also carried away by the airflow, further improving the heat dissipation efficiency.

[0026] Through the design of the heat dissipation channel 102, in conjunction with the fan 7, the light lamp 4 is cooled efficiently and quickly, thereby increasing the power of the light lamp 4 to 100-130W within a limited space.

[0027] like Figure 3 , Figure 6 , Figure 8 The outer casing 1 has a first mounting area 2 and a second mounting area 201, with the first mounting area 2 above the second mounting area 201.

[0028] Fan 7 is installed in the first installation area 2; LED 4 is installed in the second installation area 201.

[0029] Both the fan 7 and the light 4 are fixed with bolts.

[0030] The bottom of the first installation area 2 is provided with an inner protrusion 202. The bottom of the fan 7 is in contact with the inner protrusion 202, which serves as a support. Because the fan 7 will vibrate slightly during operation, the inner protrusion 202 will improve stability.

[0031] like Figure 8 The inner wall of the outer casing 1 is provided with a bottom groove 3, a middle groove 301, and an upper groove 302; the light lamp 4 is located between the bottom groove 3 and the middle groove 301; the fan 7 is located between the middle groove 301 and the upper groove 302.

[0032] The design of the bottom groove 3, the middle groove 301, and the upper groove 302 makes the upper and lower ends of the first mounting area 2 and the second mounting area 201 recessed inward. This design ensures that the heat dissipation channel 102 runs from the top of the first mounting area 2 all the way to the bottom of the second mounting area 201.

[0033] This embodiment discloses a high-power downlight, which also includes a convex mirror 5 and a bottom shell 503; The convex mirror 5 is located in the bottom groove 3; the bottom shell 503 is threaded to the bottom of the outer shell 1 and abuts against the convex mirror 5, thereby fixing the convex mirror 5 in the bottom groove 3 through the bottom shell 503.

[0034] The light emitted by the light lamp 4 is projected through the convex mirror 5.

[0035] The top sidewall of the convex mirror 5 is covered with a protective ring 501, which is made of plastic and is directly injection molded onto the top sidewall of the convex mirror 5.

[0036] The convex lens 5 is protected by a plastic protective ring 501 to prevent it from cracking due to excessive pressure.

[0037] A gasket 502 is provided between the bottom shell 503 and the convex mirror 5. The gasket 502 is made of silicone or rubber.

[0038] The top of the bottom shell 503 is provided with a first slot 6, and the outer wall of the first slot 6 is provided with an upper protrusion 601; the bottom of the outer shell 1 is provided with a second slot 602.

[0039] When the bottom shell 503 is connected by threads, the outer shell 1 part inside the second slot 602 is inserted into the first slot 6, and at the same time, the upper protrusion 601 is inserted into the second slot 602. This design improves the firmness of the bottom shell 503 after installation.

[0040] A protective plate 402 is fixedly installed at the bottom of the light lamp 4. The protective plate 402 has a hollow design. The light emitted by the LED integrated lamp bead 401 shines on the convex mirror 5 through the hollow design in the middle of the protective plate 402 and then diffuses out.

[0041] The purpose of the protective plate 402 is to prevent the convex mirror 5 from accidentally squeezing the light lamp 4 during installation, thus damaging the light lamp 4.

[0042] The top of the outer casing 1 is threadedly connected to a top shell 8, and a mounting rod 801 is fixedly connected to the top shell 8.

[0043] The top shell 8 prevents large amounts of dust from entering, and the mounting rod 801 is used to connect to other objects, such as aquarium brackets, to supplement the lighting of the aquarium.

[0044] It should be noted that when the fan 7 is turned on, the airflow enters through the heat dissipation channel 102 above the fan 7 and then blows towards the light lamp 4 for heat dissipation. The gas exits through the heat dissipation channel 102 at the central groove 301. At the same time, some gas will also enter the bottom of the light lamp 4 through the heat dissipation channel 102 below the central groove 301, forming turbulence, which dissipates heat from the bottom of the light lamp 4 and the convex mirror 5.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
