Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lamps, in particular to a lamp bottom shell convenient for heat dissipation. Background Art
[0002] The lamp bottom shell generally refers to the bottom part of the lamp, which is used to support the main structure of the lamp and fix it at the installation position. It not only provides physical support for the lamp, but also can contain electrical connection points or installation accessories. The material of the bottom shell usually includes metal, plastic or other durable materials, which is selected according to the design and use environment of the lamp.
[0003] In order to ensure good heat dissipation performance of the lamp during use, the existing lamp bottom shell usually has heat dissipation fins welded around the outside of the bottom shell. The heat dissipation fins increase the contact area between the lamp and the external air, improving the heat dissipation ability. However, during the long-term use of the lamp, a thick layer of dust often gradually accumulates on the surface of the heat dissipation fins. These dusts will not only become an obstacle to heat conduction, but may also cause local overheating, accelerating the aging process of the lamp. Therefore, it is necessary to clean the heat dissipation fins regularly.
[0004] However, in order to maximize the heat dissipation effect, the heat dissipation fins are often designed into a closely arranged structure, which makes it difficult to directly wipe them with a rag or a brush and difficult to thoroughly remove the accumulated dust in the narrow gaps between the fins. Excessive force or improper operation may also damage the fins, affecting their structural integrity and heat dissipation function. Therefore, the utility model proposes a lamp bottom shell convenient for heat dissipation. Summary of the Utility Model
[0005] Aiming at the problems in the background art, a lamp bottom shell convenient for heat dissipation is proposed. Heat dissipation fins are arranged on the outside of the shell body. By cooperating with the first limiting member and the second limiting member, the heat dissipation fins are detachably limited between the fixing plate and the shell body, which is convenient for cleaning the heat dissipation fins and avoiding the influence of dust accumulation on the heat dissipation performance of the lamp during long-term use.
[0006] The utility model proposes a lamp bottom shell convenient for heat dissipation, including
[0007] A shell body, which is set as a cylindrical structure with both ends being open structures. A tail cover is arranged on its top, and a fixing plate is arranged on its bottom. An arc-shaped cover shell extending downward is integrally formed on the outside of the fixing plate;
[0008] Heat dissipation fins, with multiple groups arranged at equal intervals in a circumferential contact manner around the central axis of the shell body, and heat dissipation channels are formed between adjacent two groups of heat dissipation fins; and
[0009] A limiting component, which includes a first limiting member and a second limiting member. The first limiting member is used to horizontally limit the heat dissipation fins on the fixing plate, and the second limiting member is used to vertically limit the heat dissipation fins on the shell body.
[0010] Preferably, a lamp board is provided at the bottom of the tail cover, lamp beads are provided at the bottom of the lamp board, and a connecting wire passing through the tail cover is connected to the lamp board.
[0011] Preferably, heat dissipation holes are formed in the arc-shaped housing, and multiple groups of heat dissipation holes are formed at equal intervals in a circumferential manner on the arc-shaped housing.
[0012] Preferably, internal threads are formed at the bottom of the inner wall of the housing for threaded connection with the lamp cover.
[0013] Preferably, the first limiting member includes paired limiting bars, and multiple groups of the limiting bars are installed on the top of the fixing plate. An insertion channel for inserting the heat dissipation fins is formed between two corresponding groups of limiting bars, and an introducing section bent outward is provided at the outer ends of two corresponding groups of limiting bars.
[0014] Preferably, the second limiting member includes an insertion ring and a threaded ring. External threads are formed at the top of the outer wall of the housing, and the threaded ring is threadedly connected to the housing through the external threads. An insertion ring is provided on the outer side of the threaded ring, and a notch for inserting the insertion ring is formed at the top of the heat dissipation fin.
[0015] Through the above technical solutions, that is, in the lamp housing disclosed in the present utility model, heat dissipation fins are provided on the outer side of the housing. By cooperating with the first limiting member and the second limiting member, the heat dissipation fins are detachably limited between the fixing plate and the housing. When cleaning the heat dissipation fins, by rotating the insertion ring, the insertion ring drives the inner threaded ring to rotate. During the rotation of the threaded ring, it is threadedly engaged with the external threads formed on the outer wall of the housing, and thus the insertion ring can be driven to move upward relative to the heat dissipation fins. During the movement, the limiting between the insertion ring and the notch formed on the heat dissipation fins is released. At this time, the heat dissipation fins can be pulled out one by one from between two corresponding groups of limiting bars, which is convenient for cleaning the heat dissipation fins and avoiding the accumulation of dust on them after long-term use, affecting the heat dissipation performance of the lamp.

[0023] Embodiment 1
[0024] As Figures 1 - 4 shown, a lamp housing bottom shell facilitating heat dissipation proposed by the present utility model includes a housing 1, heat dissipation fins 5 and a limiting assembly. The housing 1 is set as a cylindrical structure with both ends being open structures. A tail cap 2 is provided at the top thereof, and a fixing plate 3 is provided at the bottom thereof. An arc-shaped cover 4 extending downward is integrally formed on the outside of the fixing plate 3. A plurality of groups of heat dissipation fins 5 are evenly spaced around the central axis of the housing 1 on the fixing plate 3. A heat dissipation channel is formed between adjacent two groups of heat dissipation fins 5. The limiting assembly includes a first limiting member and a second limiting member. The first limiting member is used to horizontally limit the heat dissipation fins 5 on the fixing plate 3, and the second limiting member is used to vertically limit the heat dissipation fins 5 on the housing 1.
[0025] As Figure 1 and Figure 2 shown, a lamp board 6 is provided at the bottom of the tail cap 2. The lamp board 6 is relatively located inside the housing 1. Lamp beads 7 are provided at the bottom of the lamp board 6. A connecting wire 8 passing through the tail cap 2 is connected to the lamp board 6. A hanging ring is provided at the top of the tail cap 2.
[0026] As Figure 1 shown, heat dissipation holes 9 are provided on the arc-shaped cover 4. A plurality of groups of heat dissipation holes 9 are provided and are evenly spaced in a circumferential direction on the arc-shaped cover.
[0027] As Figure 2 shown, an internal thread 10 is provided at the bottom of the inner wall of the housing 1, which is used for threaded connection with a lamp shade. Through the setting of the internal thread 10, an external lamp shade can be threadedly connected to the bottom of the housing 1, which is convenient for overhauling the lamp board 6 inside the housing 1.
[0028] Embodiment 2
[0029] As Figures 1 - 4 shown, a lamp housing bottom shell facilitating heat dissipation proposed by the present utility model, on the basis of the above embodiment, further details the specific components of the limiting assembly and the limiting manner thereof for the heat dissipation fins 5.
[0030] As Figure 1 shown, the first limiting member includes a pair of limiting strips 11, and multiple groups of them are installed on the top of the fixing plate 3. An insertion channel for inserting the heat dissipation fins 5 is formed between the corresponding two groups of limiting strips 11, and an introducing section 12 bent outward is provided at the outer ends of the corresponding two groups of limiting strips 11.
[0031] As Figure 3 and Figure 4 shown, the second limiting member includes an insertion ring 13 and a threaded ring 14. An external thread 15 is opened at the top of the outer wall of the housing 1, and the threaded ring 14 is threadedly connected to the housing 1 through the external thread 15. An insertion ring 13 is provided on the outer side of the threaded ring 14, and a notch 16 for inserting the insertion ring 13 is opened at the top of the heat dissipation fins 5.
[0032] Among them, an operation ring is further provided on the outer wall of the insertion ring 13.
[0033] In summary, when the present utility model is in use, the whole lamp housing is dissipated heat through the heat dissipation fins 5 and the heat dissipation openings. When it is necessary to clean the heat dissipation fins 5, the insertion ring 13 is rotated through the operation ring. During the rotation of the insertion ring 13, the threaded ring 14 is driven to rotate synchronously. When the threaded ring 14 moves, it is in threaded cooperation with the external thread 15 opened on the housing 1, so that the threaded ring 14 drives the insertion ring 13 to move upward relatively. During the movement, the bottom end of the insertion ring 13 disengages from the notch 16 opened on the heat dissipation fins 5, that is, the limit between the insertion ring 13 and the heat dissipation fins 5 is released. At this time, the heat dissipation fins 5 can be pulled out from between the corresponding two groups of limiting strips 11 for cleaning, which improves the convenience of cleaning the heat dissipation fins 5 and avoids the influence of more dust accumulated on the heat dissipation fins 5 on the overall heat dissipation performance of the lamp housing. After cleaning, the heat dissipation fins 5 are inserted into the insertion channels between the corresponding two groups of limiting strips 11 through the introducing section 12 one by one. After being inserted in place, the side of the heat dissipation fins 5 is closely attached to the outer wall of the housing 1, and then the insertion ring 13 is rotated reversely. The insertion ring 13 moves downward under the action of the threaded ring 14. During the movement, the insertion ring 13 is caught in the notch 16 on the heat dissipation fins 5 again, that is, the limit installation of the heat dissipation fins 5 is completed.
[0034] The embodiments of the present utility model are described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the spirit of the present utility model within the knowledge scope of those skilled in the art to which it belongs.
