DETAILED DESCRIPTION

[0035] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] It should be noted here that in order to avoid obscuring the present application due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the accompanying drawings, while other details that are not closely related to the present application are omitted.

[0037] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0038] Referring to Figures 1 to 14 , the present application provides a lighting module 100, which includes a housing 10, a light source module 20, and an optical module 30. The housing 10 includes a first housing 11 and a second housing 12, with a mounting cavity 13 defined between the first housing 11 and the second housing 12. The light source module 20 is disposed within the mounting cavity 13 and abuts against the first housing 11. The optical module 30 is disposed within the mounting cavity 13 and is located between the light source module 20 and the second housing 12.

[0039] Optionally, the light source module 20 can be either a built-in light source module 21 or an external light source module 22. A first mounting structure and a second mounting structure are provided on the first shell 11. The built-in light source module 21 is adapted to be installed with the first mounting structure, and the external light source module 22 is adapted to be installed with the second mounting structure. By providing the first mounting structure and the second mounting structure in the first shell 11, wherein the first mounting structure is adapted to be installed with the built-in light source module 21, and the second mounting structure is adapted to be installed with the external light source module 22, it is possible to achieve that one shell 10 can match the functions of different light source modules 20, which can solve the problem of the singleness of the existing lighting module 100. Different mounting structures can be matched according to different light source modules 20, so that one lamp can be used for multiple purposes and meet different customization needs.

[0040] Furthermore, the first mounting structure and the second mounting structure share common structural components. That is, some structural components in the first mounting structure and the second mounting structure are identical. This arrangement allows different light source modules 20 to be mounted and connected using these common structural components, reducing the number of structural designs on the first housing 11. This simplifies the structure of the first housing 11, reduces process requirements, and saves costs, while still allowing a single lamp to serve multiple purposes.

[0041] Optionally, the second mounting structure includes the first mounting structure and has different structural components from the first mounting structure. Specifically, the second mounting structure includes the same structural components as the first mounting structure, as well as some unique structural components for connecting to the external light source module 22. This arrangement allows for adaptability to different light source modules 20 while reducing costs, thereby increasing the applicability of the housing 10 of the lighting module 100.

[0042] Alternatively, the optical module 30 may be any one of the microprism reflector 35 and the lens assembly 34, or the optical module 30 may be of other structures, without any specific limitation. The second housing 12 is also provided with a carrier 122 adapted to the optical module 30. By providing the carrier 122 on the second housing 12 to accommodate multiple optical modules 30, different optical elements can be selected according to different lighting requirements, achieving multiple uses of one lamp.

[0043] In order to clearly illustrate the structure of the lighting module 100 of the present application, the following description uses some specific embodiments as examples, but those skilled in the art will appreciate that the present invention should not be limited thereto.

[0044] 1 to 9 illustrate a first embodiment of a lighting module 100 of the present application. In this embodiment, the lighting module 100 includes a housing 10, a light source module 20, and an optical module 30. The light source module 20 is a built-in light source module 21, and the optical module 30 is a lens assembly 34.

[0045] The housing 10 includes a first housing 11, a second housing 12, and a third housing 14. The second housing 12 is disposed between the first housing 11 and the third housing 14 and is connected to the first housing 11 and the third housing 14, respectively. The first housing 11 and the second housing 12 are connected by a snap fit, and a mounting cavity 13 for mounting the light source module 20 and the optical module 30 is provided between the first housing 11 and the second housing 12. The third housing 14 is used to connect to the mounting base and is rotatably connected to the second housing 12. By rotating the second housing 12, the first housing 11 is driven to rotate synchronously, thereby changing the lighting direction of the lighting module 100.

[0046] The first housing 11 includes a mounting wall 111 and a connecting wall 112 extending from the mounting wall 111 toward the second housing 12. The mounting wall 111 is used for mounting and connecting with the light source module 20, and the connecting wall 112 is used for snap-fitting and mounting with the second housing 12.

[0047] The first mounting structure includes a first anti-mute portion 113 and a wire channel 114 provided on the mounting wall 111. The first anti-mute portion 113 is used to position and engage with the insulating shell 212 in the built-in light source module 21, and the wire channel 114 is used to engage with the first power cord 213 in the built-in light source module 21 and allow the first power cord 213 to pass through and connect to the external mains.

[0048] In this embodiment, the first anti-mistake portion 113 is a slot recessed from the mounting wall 111 away from the mounting cavity 13. Of course, in other embodiments, the first anti-mistake portion 113 may also be a protrusion extending from the mounting wall 111 into the mounting cavity 13, which is not limited here.

[0049] A wire channel 114 is provided at the opposite end of the slot, recessed from the mounting wall 111 away from the mounting cavity 13. The wire channel 114 includes a first opening facing the mounting cavity 13 and a second opening facing away from the mounting cavity 13. The first opening is larger than the second opening. This arrangement facilitates the first wire securing cavity 2122, to which the first power cable 213 is attached, to pass through the first opening into the wire channel 114, but is retained by the second opening.

[0050] Referring to FIG8 and in conjunction with FIG2 and FIG3 , the built-in light source module 21 includes a built-in light source assembly 211, an insulating shell 212, and a first power cord 213. The insulating shell 212 is disposed between the built-in light source assembly 211 and the first shell 11. The built-in light source assembly 211 and the first power cord 213 are electrically connected. Furthermore, the connected built-in light source assembly 211 is located on the side of the insulating shell 212 facing away from the mounting wall 111. Preferably, the built-in light source assembly 211 is a non-insulated light source assembly. The insulating shell 212 is disposed between the built-in light source assembly 211 and the first shell 11 to improve the safety of the lighting module 100.

[0051] In this embodiment, the built-in light source assembly 211 is a DOB optoelectronic integrated light source, comprising a first power board, a light-emitting component mounted on the first power board, and non-light-emitting components surrounding the light-emitting component. The non-light-emitting components may be electrical components, etc. A first power line 213 is electrically connected to the first power board.

[0052] The insulating housing 212 includes a top wall 2121 facing the mounting wall 111 and a peripheral wall 2124 extending from the top wall 2121 away from the mounting wall 111. A receiving groove for accommodating the built-in light source assembly 211 is formed between the top wall 2121 and the peripheral wall 2124. A positioning protrusion is provided in the receiving groove for positioning and connecting with the built-in light source assembly 211.

[0053] A second anti-fouling portion 2123 engaged with the first anti-fouling portion 113 and a first wire fixing cavity 2122 engaged with the wire passing groove 114 are provided on a side of the top wall 2121 away from the accommodating groove (ie, away from the built-in light source assembly 211 ).

[0054] In this embodiment, the second fool-proof portion 2123 is a protrusion extending from the top wall 2121 away from the receiving slot, and the protrusion engages with the slot to prevent the built-in light source module 21 and the first housing 11 from fooling around. Of course, in other embodiments, the second fool-proof portion 2123 can also be a slot recessed from the top wall 2121 toward the receiving slot, which is not limited here.

[0055] The first wire fixing cavity 2122 is formed to extend from the side of the top wall 2121 away from the accommodating groove toward the direction of the first shell 11, and can allow the first power cord 213 to pass through and clip the first power cord 213 inside. In addition, the position of the first wire fixing cavity 2122 corresponds to the wire passing groove 114, and can be clipped and installed in the wire passing groove 114.

[0056] The first wire-fixing cavity 2122 is provided with a snap-in protrusion for snapping with the first power cord 213. The first power cord 213 is provided with a snap-in groove, into which the snap-in protrusion snaps, thereby securing the first power cord 213 within the first wire-fixing cavity 2122 and at least partially housing the first wire-fixing cavity 213. Furthermore, the first power cord 213 is snap-in engaged by the first wire-fixing cavity 2122 and the wire-passing groove 114, and the first power cord 213 is configured to sequentially pass through the first wire-fixing cavity 2122 and the wire-passing groove 114 to connect to the mains electricity. By setting a first wire fixing cavity 2122 on the insulating shell 212, the first power cord 213 is at least partially accommodated in the first wire fixing cavity 2122 and is clamped with the first wire fixing cavity 2122, and then the entire first wire fixing cavity 2122 is accommodated in the wire groove 114 to fix the first power cord 213 and provide two layers of protection, thereby preventing the first power cord 213 from being pulled and damaged, and improving the service life of the lighting module 100.

[0057] Optionally, in order to enhance the installation and positioning of the built-in light source module 21 and the first shell 11 , a first positioning member 115 is further provided on the first shell 11 , and a second positioning member 225 is correspondingly provided on the insulating shell 212 of the built-in light source module 21 .

[0058] Continuing with Figures 3 and 7 , in this embodiment, mounting wall 111 is further provided with a first positioning member 115, which is a positioning post extending from mounting wall 111 into mounting cavity 13. A second positioning member 225 is provided on top wall 2121 of insulating shell 212. The second positioning member 225 is a positioning hole, into which the positioning post engages, thereby achieving a fixed connection between mounting wall 111 and insulating shell 212. In other embodiments, first positioning member 115 may be a positioning hole provided on mounting wall 111, and the second positioning member may be a positioning post extending from top wall 2121 toward mounting wall 111.

[0059] Optionally, there may be multiple positioning posts, for example two, which are respectively provided on both sides of the mounting wall 111 and are located at different positions from the first foolproof portion 113 and the wire groove 114. Similarly, there may be multiple positioning holes, and the positions of the multiple positioning holes match the positions of the positioning posts.

[0060] When the built-in light source module 21 is connected to the mounting wall 111 of the first housing 11 through the first mounting structure, one end of the optical module 30 abuts against the built-in light source module 21 and the other end is engaged with the second housing 12 .

[0061] Referring to FIG. 9 in conjunction with FIG. 2 and FIG. 3 , in this embodiment, the optical module 30 is a lens assembly 34 (e.g., a TR lens 341), which includes a lens 341 and a lens holder 342. The lens holder 342 has a mounting position for mounting the lens 341 therein, and a first end 31 and a second end 32 of the lens holder 342 abut against the optical module 30 and the second housing 12, respectively.

[0062] The lens holder 342 includes a first end 31, a second end 32, and a sidewall 33 connecting the first end 31 and the second end 32. The sidewall 33, the first end 31, and the second end 32 together form a mounting position for the lens 341. The diameter of the first end 31 is smaller than the diameter of the second end 32. The small-diameter end of the lens 341 is connected to the first end 31, and the large-diameter end of the lens 341 is connected to the second end 32.

[0063] An abutment portion extending toward the built-in light source assembly 211 is provided at the first end 31, and the four abutment portions abut against the outside of the light-emitting assembly of the built-in light source assembly 211, so that the first end 31 is covered on the outside of the light-emitting assembly, so that the light emitted by the light-emitting assembly is emitted after the optical action of the lens 341 to adjust the lighting state of the lighting module 100.

[0064] Furthermore, first end 31 is the end with the smaller diameter. A receiving space 131 for accommodating non-luminous components outside the luminous components is defined between sidewall 33 connected to first end 31 and connecting wall 112 of first housing 11. Specifically, non-luminous components (electrical components) on the first power board of the DOB optoelectronic integrated light source can be installed within receiving space 131, thereby effectively utilizing the space in housing 10 and reducing the volume of lighting module 100.

[0065] An end portion of the second end 32 extends outward to form an edge portion, and the edge portion is used to abut against and be installed in the bearing portion 122 of the second housing 12 .

[0066] To facilitate quick positioning and fastening, a first positioning and fastening portion 1223 is provided within the bearing portion 122 of the second housing 12, and a corresponding second positioning and fastening portion 321 is provided on the edge portion. The first positioning and fastening portion 1223 and the second positioning and fastening portion 321 are positioned and connected. Optionally, the first positioning and fastening portion 1223 is a positioning rib provided on the second extending wall 1221 of the bearing portion 122, and the second positioning and fastening portion 321 is a positioning groove formed by an inward depression in the edge portion.

[0067] Furthermore, a clamping block is provided on the edge portion extending toward the second housing 12 . Correspondingly, a clamping groove is provided on the bearing wall 1222 of the bearing portion 122 , and the clamping block is clamped in the clamping groove.

[0068] 2 to 7 , the first housing 11 and the second housing 12 are positioned and snap-fitted, and after being snap-fitted, they can achieve the effects of anti-disassembly and anti-light leakage.

[0069] Specifically, the first shell 11 includes a mounting wall 111 and a connecting wall 112 extending from the mounting wall 111 to the second shell 12. The connecting wall 112 is provided with at least two first snap-fit ​​portions 1121. The first snap-fit ​​portion 1121 is used to snap-fit ​​and connect with the second snap-fit ​​portion 1231 on the second shell 12 to achieve an anti-dismantling effect.

[0070] Optionally, in this embodiment, the first snap-fit ​​portion 1121 is a snap-fit ​​groove provided on the connecting wall 112 near the second housing 12. The snap-fit ​​groove is an annular groove. Of course, in other embodiments, the first snap-fit ​​portion 1121 may also be a snap-fit ​​protrusion 1232. This is not limited here.

[0071] The connecting wall 112 includes an end portion close to the second housing 12, and a clearance groove 1122 is formed inside the end portion. The clearance groove 1122 is used to accommodate the lip 124 of the second housing 12, thereby completely wrapping the second housing 12 within the first housing 11 to prevent light leakage.

[0072] Furthermore, because the clearance groove 1122 is also annular and is located below the snap groove, a snap step is formed between the clearance groove 1122 and the snap groove. This snap step abuts the upper surface of the lip 124 of the second shell 12. Since the snap step is located below the snap groove, when the snap step is subjected to external force, the force is not applied to the first snap portion 1121 and the second snap portion 1231, thereby preventing the first shell 11 from falling off.

[0073] The second housing 12 includes a base 121 and a first extension wall 123 extending from the base 121 toward the first housing 11. The first extension wall 123 has a light outlet 17 on its inner side. The first extension wall 123 is provided with at least two second latching portions 1231. The outer edge of the first extension wall 123 is provided with an outwardly extending lip 124. The first and second latching portions 1121, 1231 are connected by a snap fit. The lip 124 is received within the clearance groove 1122 and is enclosed by the end portion. This snap fit between the first and second latching portions 1121, 1231 ensures that the housing 10 is tamper-proof. Furthermore, when the first and second housings 11, 12 are snap-fitted together, the lip 124 of the second housing 12 is received within the clearance groove 1122 of the first housing 11 and enclosed by the end portion of the first housing 11, thereby preventing light leakage.

[0074] In this embodiment, the second locking portion 1231 is a locking protrusion 1232 provided on the first extending wall 123 . Of course, in other embodiments, the second locking portion 1231 may also be a locking groove.

[0075] Furthermore, the snap-on protrusion 1232 is an annular, inclined snap-on protrusion 1232. The snap-on protrusion 1232 includes a snap-on surface 1234 facing the second shell 12, an inclined guide surface 1233 facing the lip 124, and two oblique end surfaces 1235 connecting the snap-on surface 1234 and the inclined guide surfaces 1233. Furthermore, the edge connecting the two oblique end surfaces 1235 on the snap-on surface 1234 is an arcuate edge. In other words, the snap-on surface 1234 of the snap-on protrusion 1232 is an arcuate surface, thereby matching the arcuate surface of the snap-on groove. By providing the inclined snap-on protrusion 1232, the area between the snap-on protrusion 1232 and the snap-on groove can be increased, thereby achieving an anti-disassembly effect. The inclined guide surface 1233 is provided to guide the snap-on connection between the second shell 12 and the first shell 11.

[0076] Optionally, a plurality of snap-fit ​​protrusions 1232 are provided on the first extension wall 123, and the plurality of snap-fit ​​protrusions 1232 are arranged circumferentially along the first extension wall 123. Two adjacent snap-fit ​​protrusions 1232 are arranged in a mirror image. Such an arrangement can improve the stability of the snap-fit ​​protrusions 1232 and the snap-fit ​​groove.

[0077] The connecting wall 112 is also provided with a stress-relieving groove 1236 that is aligned with the inclination of the latching protrusion 1232. The stress-relieving groove 1236 is positioned adjacent to the latching protrusion 1232 and includes a pair of inclined surfaces 1237. The inclined surfaces 1237 adjacent to the latching protrusion 1232 are connected to the inclined end surface 1235 and lie on the same plane. The provision of the stress-relieving groove 1236 reduces the deformation distance of the first extension wall 123.

[0078] Furthermore, in order to quickly connect the first shell 11 and the second shell 12, a first docking portion 1123 for docking with the second shell 12 is provided on the inner side of the connecting wall 112.
