[0002] This application claims priority to Chinese Patent Application No. 202420875015.1, filed on April 24, 2024, entitled “Ceiling Lamp”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of lighting equipment technology, and more particularly to a ceiling light. Background Technology

[0004] Ceiling lights are a type of lighting fixture widely used in large, spacious venues. They can be used in factories, warehouses, gas stations, construction sites, highway toll stations, mining areas, train stations, docks, large shopping malls, exhibition halls, stadiums, and other similar locations.

[0005] In related technologies, both the power supply module and the light source module of the ceiling light are mounted on the lampshade. In this case, the heat generated by the power supply module and the light source module is transferred to the lampshade, causing a large amount of heat to accumulate there. This makes it difficult for the heat generated by the power supply module and the light source module to dissipate in time, leading to damage from overheating. Therefore, the ceiling lights in these technologies have poor heat dissipation performance. Summary of the Invention

[0006] This application discloses a ceiling light to solve the problem of poor heat dissipation performance of ceiling lights.

[0007] To solve the above problems, this application adopts the following technical solution:

[0008] A ceiling light includes: a power supply assembly comprising a power supply housing and a power supply module, the power supply module being located within the power supply housing; a light source assembly comprising a lampshade and a light source module; the lampshade having a light source groove, the light source module being disposed within the light source groove, and the power supply housing being located on the side of the lampshade opposite to the light source groove; and an isolator disposed between the power supply housing and the lampshade, the isolator being used to isolate the power supply housing and the lampshade to form a heat dissipation gap between the power supply housing and the lampshade.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0019] As shown in Figures 1 to 7, this application discloses a ceiling light, which includes a power supply assembly 100, a light source assembly 200, and an isolation component 300.

[0020] The power supply assembly 100 includes a power supply housing 110 and a power supply module 120. The power supply housing 110 provides installation space for other components of the power supply assembly 100. The power supply housing 110 has a receiving cavity, and the power supply module 120 is disposed within the receiving cavity. The power supply module 120 includes, but is not limited to, electronic devices such as power supplies, transformers, circuit boards, relays, and frequency converters. The specific structure and principle of the power supply module 120 are well-known technologies and will not be described in detail herein.

[0021] The light source assembly 200 includes a lampshade 210 and a light source module 220, with the light source module 220 disposed within the lampshade 210. Specifically, the lampshade 210 has a light source slot 213, and the light source module 220 is disposed within the light source slot 213. The aforementioned power supply housing 110 is located on the side of the lampshade 210 facing away from the light source slot 213. In this case, the power supply housing 110 is positioned above the lampshade 210, ensuring that the power supply housing 110 does not obstruct the light from the light source assembly 200. The lampshade 210 serves both as the mounting base for the light source module 220 and as a reflector and focuser for the light emitted by the light source module 220. In one specific embodiment, the light source module 220 may include a light source board 221, which is essentially a circuit board with LEDs mounted on it. Of course, the light source module 220 may also include a lens 222, which can cover the light-emitting side of the light source plate 221, thereby improving the light emission brightness of the light source module 220 and thus giving the light source module 220 better optical performance. In another optional solution, the side surface of the light source slot 213 may also be a reflective surface, thereby further improving the brightness of the light source assembly 200.

[0022] An isolator 300 is disposed between the power supply housing 110 and the lamp cover 210. The isolator 300 is used to isolate the power supply housing 110 and the lamp cover 210, so that a heat dissipation gap 600 is formed between the power supply housing 110 and the lamp cover 210. It can also be understood that the isolator 300 has a certain length, so as to separate the power supply housing 110 and the lamp cover 210 by a certain distance, so that the power supply housing 110 and the lamp cover 210 do not directly contact or overlap.

[0023] In the embodiments disclosed in this application, the power module 120 is detached from the lamp cover 210, so that the power module 120 and the light source module 220 can be cooled separately, thereby avoiding the risk of heat accumulation. As a result, both the power module 120 and the light source module 220 have high heat dissipation performance, thus improving the heat dissipation performance of the ceiling light.

[0024] Furthermore, the power supply housing 110 and the lampshade 210 are isolated by the insulating member 300, thereby forming a heat dissipation gap 600 between them. At this time, the insulating member 300 separates the power supply housing 110 and the lampshade 210, thus preventing heat transfer and accumulation between the power module 120 and the light source module 220. It also increases the contact area between the power supply housing 110 and the lampshade 210 and the air, and improves air convection performance, thereby improving the heat dissipation performance of the light source assembly 200 and the power assembly 100. Therefore, it effectively avoids the risk of damage to the ceiling light due to excessive temperature. Therefore, compared with ceiling lights in related technologies, the ceiling light disclosed in this application has better heat dissipation performance.

[0025] Furthermore, the power module 120 in this application is detached from the lamp cover 210 and installed in a separate housing. Therefore, it is equivalent to the power module 120 being external, which results in a lower operating temperature for the power module 120 and thus effectively improves its service life.

[0026] In the embodiments disclosed in this application, since the power supply module 120 does not need to be installed in the lampshade 210, the structure of the lampshade 210 is simplified, thereby reducing the manufacturing cost of the ceiling light.

[0027] In one embodiment, the isolator 300, the power supply housing 110, and the lampshade 210 can be separate components. This means that the isolator 300 needs to be manufactured individually, and the isolator 300 needs to be assembled with both the power supply housing 110 and the lampshade 210. Alternatively, the isolator 300 can be connected to both the power supply housing 110 and the lampshade 210 using methods such as welding, riveting, or snap-fitting.

[0028] In one alternative embodiment, one of the power supply housing 110 and the lampshade 210 may be integrally formed with the isolator 300, while the other may be connected to the isolator 300.

[0029] Specifically, the power supply housing 110 can be integrally formed with the isolator 300, and the end of the isolator 300 facing away from the power supply housing 110 can be connected to the lampshade 210 by welding, riveting, snap-fitting, or other methods. Alternatively, the lampshade 210 can be integrally formed with the isolator 300, and the end of the isolator 300 facing away from the lampshade 210 can be connected to the power supply housing 110 by welding, riveting, snap-fitting, or other methods.

[0030] In this design, the isolator 300 is integrally formed with one of the power supply housing 110 and the lampshade 210, which simplifies the assembly structure of the ceiling light. Furthermore, the integral formation of the isolator 300 with one of the power supply housing 110 and the lampshade 210 also serves to position the isolator 300, eliminating the need for additional positioning structures and thus effectively improving the assembly efficiency of the ceiling light.

[0031] In the above embodiments, the isolator 300 can be disposed near the middle of the power supply housing 110 and the lamp cover 210. However, if the isolator 300 is supported in the middle of the power supply housing 110 and the lamp cover 210, it is easy to cause the power supply housing 110 and the lamp cover 210 to tilt, thereby affecting the reliability of the ceiling light.

[0032] Based on this, in another optional embodiment, the isolator 300 may include a central support post 310 and at least two edge support posts 320. The central support post 310 may be located between the at least two edge support posts 320, and the at least two edge support posts 320 may be arranged at circumferential intervals along the power supply housing 110. In this case, the central support post 310 is located near the middle of the power supply housing 110 and the lampshade 210. This can be understood as the central axis of the central support post 310 coinciding with the central axis of the power supply housing 110 or the lampshade 210; or, the central axis of the central support post 310 and the central axis of the power supply housing 110 or the lampshade 210 are both located in the middle within a certain range. The at least two edge support posts 320 are located near the edges of the power supply housing 110 and the lampshade 210.

[0033] In this design, the central support column 310 supports the middle position of the power supply housing 110 and the lampshade 210, while at least two edge support columns 320 support the edges of the power supply housing 110 and the lampshade 210. In this case, the at least two edge support columns 320 can make the edge positions of the power supply housing 110 and the lampshade 210 relatively balanced, thereby avoiding the risk of tilting between the power supply housing 110 and the lampshade 210, and further improving the reliability of the ceiling light.

[0034] Optionally, the number of edge support columns 320 can be two or three. Of course, the number of edge support columns 320 can be flexibly selected according to the volume of the ceiling light, and this article does not impose any restrictions.

[0035] In the above embodiments, the power module 120 and the light source module 220 are connected by a cable, thereby realizing the electrical connection between the power module 120 and the light source module 220. Typically, the power housing 110 and the lampshade 210 have corresponding wiring holes for inserting cables. However, having too many wiring holes in the power housing 110 and the lampshade 210 is detrimental to the waterproofing and dustproofing of the ceiling light. Furthermore, some cables between the power housing 110 and the lampshade 210 are exposed, which is easily damaged and detracts from the aesthetics of the ceiling light.

[0036] Based on this, in another optional embodiment, the central support column 310 may have a cable channel 311, the power supply housing 110 may have a first through hole 1101, and the lampshade 210 may have a second through hole 211, which may be connected to the light source slot 213. The first through hole 1101 may be connected to the second through hole 211 via the cable channel 311. Cables used to connect the power module 120 and the light source module 220 may pass through the first through hole 1101, the cable channel 311, and the second through hole 211 in sequence.

[0037] In this design, the central support column 310 can assist in cable routing. Both ends of the central support column 310 can seal or block the first through hole 1101 and the second through hole 211, thus improving the waterproofing and dustproofing of the ceiling light. Furthermore, routing the cables through the central support column 310 avoids cable exposure, thereby improving cable safety. Simultaneously, concealed cables also make the ceiling light more aesthetically pleasing.

[0038] In one embodiment, where one of the power supply housing 110 and the lampshade 210 is an integral part of the isolation member 300, the first perforation 1101 and the second perforation 211 can be considered as part of the cable channel 311.

[0039] In another optional embodiment, the edge support column 320 may have a through channel 3201, the power supply housing 110 may have a first connection hole 1102, and the lampshade 210 may have a second connection hole 212, which can communicate with the light source slot 213. The first connection hole 1102 can communicate with the second connection hole 212 through the through channel 3201. The ceiling light may also include a connecting bolt 410, which can pass through the second connection hole 212, the through channel 3201, and the first connection hole 1102 in sequence. The lampshade 210, the isolator 300, and the power supply housing 110 can all be connected by the connecting bolt 410.

[0040] In this design, the connecting bolt 410 can be concealed within the insulating component 300, thus avoiding the risk of the connecting bolt 410 being exposed and consequently preventing damage to it, thereby extending its service life. Simultaneously, the concealed connecting bolt 410 also enhances the aesthetics of the ceiling light. Therefore, this design improves both the service life of the connecting bolt 410 and the aesthetics of the ceiling light.

[0041] In addition, the connection between the power supply assembly 100, the light source assembly 200 and the isolation component 300 can be achieved by connecting bolt 410, thus optimizing the connection structure of the ceiling light, thereby simplifying the processing technology of the ceiling light and reducing the manufacturing cost of the ceiling light.

[0042] In one embodiment, where one of the power supply housing 110 and the lampshade 210 is integrally formed with the isolator 300, the first connection hole 1102 and the second connection hole 212 can be considered as part of the through channel 3201.

[0043] The second connecting hole 212, the through channel 3201 and the first connecting hole 1102 mentioned above can all be threaded holes, or the second connecting hole 212 and the through channel 3201 can be non-threaded holes and the first connecting hole 1102 can be a threaded hole; or, the second connecting hole 212, the through channel 3201 and the first connecting hole 1102 can all be non-threaded holes, and other structures that are threadedly connected to the connecting bolt 410 are provided inside the power supply housing 110.

[0044] In the above embodiment, the edge support column 320 supports a large area, thus bearing a large weight, making it prone to breakage. In another optional embodiment, the edge support column 320 may include a column body 321 and at least one reinforcing rib 322, with the reinforcing rib 322 connected to the column body 321. The column body 321 may have a through-channel 3201. This design further improves the strength of the edge support column 320, thereby avoiding the risk of breakage.

[0045] In one embodiment, the number of reinforcing ribs 322 can be two, and the column portion 321 can be located between the two edge support columns 320. Alternatively, the reinforcing ribs 322 can be distributed circumferentially along the column portion 321. Of course, the number of reinforcing ribs 322 can also be other than those specified in this paper.

[0046] Optionally, the column part 321 can be a cylindrical structure, a prismatic structure, or other structures, which are not limited in this article.

[0047] In another alternative embodiment, the power supply housing 110 may include a first housing 111 and a second housing 112, which can form a receiving cavity in which the power module 120 is located. The second housing 112 is located between the lampshade 210 and the first housing 111. The isolator 300 may be located between the second housing 112 and the lampshade 210, a first connecting hole 1102 may be formed in the second housing 112, and a connecting bolt 410 may be threadedly connected to the first housing 111.

[0048] In this design, the lampshade 210, the isolator 300, the second housing 112, and the first housing 111 are all connected by connecting bolts 410. This simplifies the connection structure between the first housing 111 and the second housing 112. No additional connecting components are needed between the first housing 111 and the second housing 112, resulting in a simpler power supply housing structure and lower manufacturing costs.

[0049] In an alternative embodiment, the aforementioned isolation element 300 may be integrally formed with the second housing 112.

[0050] In an alternative embodiment, the ceiling light may also include a sling attachment 500 and a threaded component 420. The first housing 111 has a threaded connection hole 1103, and the sling attachment 500 can be connected to the first housing 111 via the threaded component 420 and the threaded connection hole 1103. In this case, the ceiling light can be connected to a mounting base via the sling attachment 500, which can be a ceiling, support rod, or other structure.

[0051] In one embodiment, one end of the threaded connection hole 1103 can be used for threaded connection with the threaded component 420, and the other end of the threaded connection hole 1103 can be used for threaded connection with the connecting bolt 410. In this solution, the threaded connection hole 1103 can be used to fix both the threaded component 420 and the connecting bolt 410, thus reducing the number of threaded holes on the first housing 111 and further simplifying the structure of the power supply housing 110.

[0052] In another alternative, the lens 222 of the light source module 220 can be connected to the lampshade 210. Specifically, the lens 222 can be connected to the lampshade 210 via bolts, rivets, clips, or other components. A connecting bolt 410 can pass through the light source plate 221, and the light source plate 221 can be connected to the lampshade 210 via the connecting bolt 410. In this configuration, the light source plate 221 is located between the lens 222 and the lampshade 210. The connection between the lens 222 and the lampshade 210 clamps and fixes the light source, while the connecting bolt 410 pre-tightens the light source plate 221, thus providing better fixation for the light source plate 221.

[0053] To further improve the heat dissipation performance of the ceiling light, in one optional embodiment, at least one of the power supply housing 110 and the lampshade 210 may be provided with multiple heat dissipation fins, which may be arranged at intervals along the circumference of the lampshade 210 or the power supply housing 110. This solution can further improve the heat dissipation performance of the ceiling light.

[0054] In one alternative embodiment, the outer peripheral surface of the power supply housing 110 may be provided with multiple heat dissipation fins, which may be arranged at intervals along the circumference of the power supply housing 110. In this case, the heat dissipation fins can increase the heat dissipation area of ​​the power supply housing 110, thereby improving the heat dissipation performance of the power supply component 100.

[0055] In another embodiment, the lampshade 210 can be provided with multiple heat dissipation fins on the side opposite to the light source module 220, and these fins can be arranged at intervals along the circumference of the lampshade 210. In this case, the heat dissipation fins can increase the heat dissipation area of ​​the lampshade 210, thereby improving the heat dissipation performance of the light source assembly 200.

[0056] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0057] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
