[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0034] refer to Figures 1 to 12 This application discloses a lighting module, which includes a lamp arm 10, a lamp holder 20, a first light source assembly 30, and a second light source assembly 40.

[0035] The lamp holder 20 is one of the basic components, which can provide a support and installation base for the first light source assembly 30 and the second light source assembly 40, etc.; the lamp arm 10 is another basic component, which can provide a support and installation base for other components (such as the third light source assembly 50 described below).

[0036] In some embodiments, one end of the lamp arm 10 can be connected to the lamp holder 20, so as to connect the lamp holder 20 to other structures through the lamp arm 10. Optionally, the lamp arm 10 can be a long strip structure, such as a straight long strip structure, an arc long strip structure or other forms, which are not specifically limited here.

[0037] The first light source component 30 is disposed at at least one end of the lamp holder 20 along its own axis, thus the lamp holder 20 can be used to support and install the first light source component 30. In some embodiments, the first light source component 30 may be disposed at one end of the lamp holder 20 along its axis; of course, in order to improve illumination and aesthetics, the first light source component 30 may also be disposed at both ends of the lamp holder 20 along its axis, and the two sets of first light source components 30 may be symmetrically arranged, which can help improve illumination and the overall aesthetics of the lamp module.

[0038] The second light source assembly 40 is arranged circumferentially around the outside of the lamp holder 20. This allows the second light source assembly 40 to emit light on the circumferential surface of the lamp holder 20, improving the brightness of the lighting module and enhancing its overall aesthetics in conjunction with the distribution of the first light source assembly 30. Optionally, the second light source assembly 40 can be a flexible wire light source assembly, such as one including a flexible strip and equipped with multiple LED beads.

[0039] In this embodiment, a first light source assembly 30 is provided at the end of the lamp holder 20 along the axial direction, and a second light source assembly 40 is provided on the outer side of the lamp holder 20 in the circumferential direction. This increases the number of light sources, which is beneficial to improving the overall brightness of the lamp module. It also realizes that multiple light source assemblies are distributed in different positions of the lamp module, so that each part of the lamp module is fully utilized. In addition, the distribution of the first light source assembly 30 and the second light source assembly 40 can also improve the overall appearance performance of the lamp module, thereby improving the user experience.

[0040] To facilitate the installation of the second light source assembly 40, the outer peripheral surface of the lamp holder 20 may be provided with an annular groove 21 extending circumferentially, such as... Figure 11 and Figure 12 As shown, the second light source assembly 40 is arranged in a ring around the annular groove 21. This arrangement allows the second light source assembly 40 to be accommodated within the annular groove 21, preventing it from bulging outwards relative to the outer periphery of the lamp holder 20, thus avoiding increased volume, accidental contact, and aesthetic issues. For example, the second light source assembly 40 can be annular; however, for ease of installation, it can also be an annular structure with an opening. Furthermore, the second light source assembly 40 can be bonded to the annular groove 21.

[0041] Furthermore, the lighting module may also include a transparent strip 70, such as Figure 1 and Figure 2 As shown, the transparent strip 70 is disposed on the lamp holder 20 and covers the outside of the second light source assembly 40. It can provide a certain degree of protection for the second light source assembly 40 and also ensure that the light emitted by the second light source assembly 40 can pass through the transparent strip 70 and be emitted outward.

[0042] In some more specific embodiments, the transparent strip 70 can be arranged inside the annular groove 21. In this way, the second light source component 40 can be surrounded by the transparent strip 70 and the bottom of the annular groove 21, thereby accommodating the second light source component 40 and providing protection and light transmission through the transparent strip 70.

[0043] In other embodiments, the second light source component 40 may also be arranged around the outer periphery of the lamp holder 20. This arrangement can also improve the overall brightness, aesthetics and space utilization of the lamp module by having the second light source component 40 cooperate with the first light source component 30.

[0044] In some embodiments, the lighting module may further include a third light source assembly 50, which is disposed on the lamp arm 10 and arranged along the extending direction of the lamp arm 10. This allows the third light source assembly 50 to emit light at the lamp arm 10, thereby improving the brightness of the lighting module and enhancing its overall aesthetics in conjunction with the distribution of the first light source assembly 30 and the second light source assembly 40. Optionally, the third light source assembly 50 may be a linear light source assembly, such as one comprising a strip and equipped with multiple LED beads.

[0045] To facilitate the installation of the third light source assembly 50, elongated slots 11 can be provided on both opposite sides of the lamp arm 10, such as... Figure 10 As shown, each elongated slot 11 is arranged along the extending direction of the lamp arm 10, and the third light source assembly 50 is disposed in the elongated slot 11. Based on this arrangement, the third light source assembly 50 can be accommodated by the elongated slot 11, preventing the third light source assembly 50 from protruding outward relative to the wall of the lamp arm 10, thus increasing its volume, making it easy to be accidentally bumped, and affecting its aesthetics. For example, the third light source assembly 50 can be a long strip structure.

[0046] Furthermore, the lighting module may also include a transparent strip 70, which is disposed on the lamp arm 10 and covers the outside of the third light source assembly 50. This transparent strip 70 can provide a certain degree of protection for the third light source assembly 50 and can also ensure that the light emitted by the third light source assembly 50 can pass through the transparent strip 70 and be emitted outward.

[0047] In some more specific embodiments, the transparent strip 70 can be set inside the long groove 11. In this way, the third light source component 50 can be surrounded by the transparent strip 70 and the bottom of the long groove 11, thereby accommodating the third light source component 50 and providing protection and light transmission through the transparent strip 70.

[0048] It should be noted that the transparent strip 70 provided on the lamp holder 20 and the transparent strip 70 provided on the lamp arm 10 can be a whole. That is, the transparent strip 70 extends from the long groove 11 on one side of the lamp arm 10 to the annular groove 21 of the lamp holder 20, and then extends to the long groove 11 on the other side of the lamp arm 10, thereby sequentially covering the third light source assembly 50 on one side of the lamp arm 10, the second light source assembly 40 on the outer periphery of the lamp holder 20, and the third light source assembly 50 on the other side of the lamp arm 10.

[0049] Of course, the transparent strip 70 provided on the lamp holder 20 and the transparent strip 70 provided on the lamp arm 10 can also be separate transparent strips 70. That is, a strip-shaped transparent strip 70 is provided in the long groove 11 on one side of the lamp arm 10, an arc-shaped transparent strip 70 is provided in the annular groove 21 of the base, and a strip-shaped transparent strip 70 is provided in the long groove 11 on the other side of the lamp arm 10. This method can also cover the third light source component 50 on one side of the lamp arm 10, the second light source component 40 on the outer periphery of the lamp holder 20, and the third light source component 50 on the other side of the lamp arm 10 respectively.

[0050] Optionally, the lamp holder 20 can be a ring structure, or other shapes, which are not specifically limited here.

[0051] To achieve a stable connection between the lamp arm 10 and the lamp holder 20, the lamp holder 20 may have an internal mounting cavity 22, such as... Figure 11 and Figure 12 As shown, the outer peripheral surface of the lamp holder 20 may be provided with a mounting hole 23 communicating with the mounting cavity 22, and at least one end of the lamp holder 20 along its own axial direction may be provided with a window 25 communicating with the mounting cavity 22; one end of the lamp arm 10 passes through the mounting hole 23 into the mounting cavity 22, and the side wall of the lamp arm 10 blocks the corresponding window 25. In this way, the lamp arm 10 and the lamp holder 20 can be installed together, which is beneficial to improving the reliability and stability of the connection between the lamp arm 10 and the lamp holder 20; furthermore, fasteners can be used to fasten the lamp arm 10 and the lamp holder 20 to further ensure the reliability and stability of the connection between the lamp arm 10 and the lamp holder 20.

[0052] In some embodiments, the lighting module may further include a circuit board 60 disposed within the lamp arm 10, such as Figure 3 As shown, the first light source assembly 30, the second light source assembly 40, and the third light source assembly 50 are respectively connected to the circuit board 60; in addition, the circuit board 60 can also be connected to an external power source via wire 80 to supply power to the first light source assembly 30, the second light source assembly 40, and the third light source assembly 50.

[0053] Considering that the circuit board 60 is located within the mounting cavity 22, the first light source assembly 30 is disposed on the lamp holder 20, allowing the first light source assembly 30 to be directly connected to the circuit board 60. For example, the first light source assembly 30 and the circuit board 60 can be connected via pins.

[0054] Considering that the third light source component 50 is located on the lamp arm 10, one end of the third light source component 50 can pass through the mounting hole 23 and into the mounting cavity 22 along with the lamp arm 10. In this way, the third light source component 50 can be connected to the circuit board 60 located in the mounting cavity 22. For example, the connection can be achieved by means of wires, conductive sheets, etc.

[0055] The second light source assembly 40 is disposed around the outside of the lamp holder 20, and at least a portion of the second light source assembly 40 passes through the mounting hole 23 into the mounting cavity 22 and is connected to the third light source assembly 50. In this way, the third light source assembly 50 can be connected in series with the second light source assembly 40 to supply power to the second light source assembly 40.

[0056] For example, the second light source assembly 40 can be an annular structure with an opening, one end of which is bent inward to form a fixing piece, so as to be connected to the lamp arm 10 and the third light source assembly 50 through the fixing piece.

[0057] refer to Figure 8 , Figure 11 and Figure 12 In some embodiments, the lamp holder 20 may include a first base 20a and a second base 20b that are detachably connected, and the first base 20a and the second base 20b can be spliced ​​together to form the entire lamp holder 20.

[0058] Furthermore, the first base 20a may be provided with a first mounting groove 22a and a first retaining groove 23a that are connected, and the second base 20b may be provided with a second mounting groove 22b and a second retaining groove 23b that are connected. Thus, when the first base 20a and the second base 20b are assembled, the first mounting groove 22a and the second mounting groove 22b interlock to form a mounting cavity 22 to accommodate one end of the lamp arm 10, and the first retaining groove 23a and the second retaining groove 23b interlock to form a mounting hole 23 to allow the lamp arm 10 to pass through. It should be noted that the first mounting groove 22a and the second mounting groove 22b can fasten the lamp arm 10 between them, and the first retaining groove 23a and the second retaining groove 23b can fasten the lamp arm 10 between them. This improves the reliability and stability of the assembly between the lamp base 20 and the lamp arm 10.

[0059] In addition, the first base 20a and the second base 20b can be connected by fasteners such as screws and bolts; of course, the lamp arm 10 can also be fastened to at least one of the first base 20a and the second base 20b by fasteners such as screws and bolts.

[0060] Optionally, both the first mounting groove 22a and the second mounting groove 22b may be provided with windows 25. In this way, when the lamp arm 10 passes through the mounting cavity 11, the two opposite side walls of the lamp arm 10 respectively block the windows 25 of the first mounting groove 22a and the windows 25 of the second mounting groove 22b.

[0061] It should be noted that the main function of setting window 25 is to enable the first light source assembly 30 to be directly fixed to the lamp arm 10, so as to ensure the installation stability of the first light source assembly 30.

[0062] To facilitate the installation of the second light source assembly 40, a first annular recessed groove can be provided at the end of the first base 20a near the second base 20b, and a second annular recessed groove can be provided at the end of the second base 20b near the first base 20a. Thus, when the first base 20a and the second base 20b are assembled, the first annular recessed groove and the second annular recessed groove interlock to form the entire annular groove 21, which is convenient for accommodating the second light source assembly 40 and for facilitating the installation of the second light source assembly 40.

[0063] refer to Figures 3 to 7 In some embodiments, the first light source assembly 30 may include a light source plate 31, a light guide 32, a diffuser 33, and a transparent cover 34. The light source plate 31 is disposed at at least one end of the lamp holder 20 along its own axis and is connected to the circuit board 60 via pins. It should be noted that when the first light source assembly 30 is disposed at one end of the lamp holder 20 along its own axis, the light source plate 31 is also disposed at one end of the lamp holder 20 along its own axis; when the first light source assembly 30 is disposed at both ends of the lamp holder 20 along its own axis, the light source plate 31 is also disposed at both ends of the lamp holder 20 along its own axis.

[0064] Optionally, the light source board 31 may be provided with positioning holes, and the lamp holder 20 may be provided with positioning posts. The precise installation of the light source board 31 on the lamp holder 20 can be achieved by the cooperation of the positioning posts and positioning holes.

[0065] The light guide 32 is connected to the lamp arm 10 and is positioned opposite to the light-emitting element on the corresponding light source plate 31. Thus, the light emitted by the light-emitting element can be propagated through the light guide 32. Optionally, the end of the light guide 32 facing the light source plate 31 can be provided with a recess, allowing the light-emitting element on the light source plate 31 to be located in the recess. This provides space for the light-emitting element and also encloses it to prevent light leakage.

[0066] A diffuser 33 is disposed on the lamp holder 20 and covers the outside of the light guide 32. In this way, the light guided by the light guide 32 can be diffused through the diffuser 33, which is beneficial to expanding the lighting area.

[0067] A transparent cover 34 is placed on the lamp holder 20 and covers the outside of the diffuser 33. In this way, the diffused light can be emitted outward and the diffuser 33 and other components can be protected.

[0068] To ensure the installation stability of the diffuser 33, an edge structure 331 can be provided on the outer side of the port of the diffuser 33, such as... Figure 5As shown, the edge structure 331 is provided with a first extrusion surface 3311; correspondingly, the inner side of the port of the transparent cover 34 is provided with a second extrusion surface 341. Based on this, when the transparent cover 34 is provided on the lamp holder 20, the second extrusion surface 341 abuts against the first extrusion surface 3311 so that the diffuser cover 33 is tightly connected to the lamp holder 20.

[0069] Based on the above settings, the diffuser 33 can be firmly fixed to the lamp holder 20 by the transparent cover 34, ensuring the installation stability of the diffuser 33. Furthermore, after removing the transparent cover 34 from the lamp holder 20, the diffuser 33 can be directly removed, improving the disassembly and assembly efficiency of the diffuser 33.

[0070] Optionally, the light guide 32 can be a light guide column, etc.; the light emitting element can be an LED light; the diffuser 33 can be a plastic cover; and the transparent cover 34 can be a glass cover or a plastic cover.

[0071] refer to Figure 8 In some embodiments, at least one end of the lamp holder 20 along its own axis may be provided with an assembly groove 24, and at least a portion of the first light source assembly 30 may be installed into the corresponding assembly groove 24 to ensure the firmness and reliability of the assembly between the first light source assembly 30 and the lamp holder 20.

[0072] Specifically, the ports of the diffuser 33 and the transparent cover 34 are located in the assembly groove 24, so that the side wall of the assembly groove 24 can play a certain limiting role for the diffuser 33 and the transparent cover 34.

[0073] Additionally, one of the outer side of the port of the transparent cover 34 and the inner wall of the mounting groove 24 may be provided with a latching protrusion 241, and the other may be provided with a third latching groove 342, with the latching protrusion 241 and the third latching groove 342 engaging. Based on this configuration, the engagement of the latching protrusion 241 and the latching groove facilitates the assembly and disassembly of the transparent cover 34, further simplifying the assembly and disassembly of the diffuser cover 33. Based on this configuration, the engagement or disassembly of the latching protrusion 241 and the third latching groove 342 can be achieved by rotating the transparent cover 34.

[0074] In some embodiments, the lamp arm 10 is provided with a channel 12 arranged along its own extension direction, and the circuit board 60 can be located in the channel 12 of the lamp arm 10 to provide a receiving space for the circuit board 60 through the channel 12.

[0075] Furthermore, the lighting module may also include a wire 80 extending in the channel 12 and connected to the circuit board 60; in addition, the wire 80 may also be connected to an external power source to transfer electrical energy from the external power source to the circuit board 60, and then distribute it to the first light source assembly 30, the second light source assembly 40 and the third light source assembly 50 through the circuit board 60.

[0076] Optionally, the wire 80 can be soldered to the circuit board 60. Alternatively, plug-in terminals can be used to achieve plug-in connection.

[0077] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
