DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Referring to Figures 1 to 12 , the present application provides a lamp 100, comprising a housing 10, a light source module 20, and an optical module 30. The housing 10 comprises a first housing 11, a second housing 12, and a third housing. A mounting cavity 13 is 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.

[0036] Specifically, the shell 10 includes a first shell 11, a second shell 12 and a third shell 14. The second shell 12 is arranged between the first shell 11 and the third shell 14, and is connected to the first shell 11 and the third shell 14 respectively. The first shell 11 and the second shell 12 are snap-connected, and there is a mounting cavity 13 between the first shell 11 and the second shell 12 for mounting the light source module 20 and the optical module 30. Among them, the light source module 20 is mainly connected to the first shell 11, the optical module 30 is clamped between the light source module 20 and the second shell 12, and the second shell 12 and the third shell 14 are rotatably connected. The third shell 14 is used to connect to the mounting base, and by rotating the second shell 12, the first shell 11 is driven to rotate synchronously, so that the lighting direction of the lamp 100 can be changed.

[0037] 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.

[0038] The mounting wall 111 is provided with a wire channel 114 for the passage of the power cord 23. The wire channel 114 is 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 area of ​​the first opening is larger than the area of ​​the second opening. This arrangement facilitates the passage of the wire securing cavity 2221, with the power cord 23 secured thereto, into the wire channel 114 through the first opening, but is retained by the second opening.

[0039] The light source module 20 includes a light source assembly 21, a light source bracket 22, and a power line 23. The light source assembly 21 is electrically connected to the power line 23 and is detachably connected to the light source bracket 22.

[0040] The light source bracket 22 includes a mounting portion 221 for mounting the light source assembly 21 and an outer edge portion 222 disposed on an outer periphery of the mounting portion 221 .

[0041] The mounting portion 221 is used to detachably mount the light source assembly 21. By providing the mounting portion 221 to detachably mount the light source assembly 21, the light source bracket 22 can be adapted to accommodate different light source assemblies 21. For example, the light source assembly 21 can be an insulated light source assembly 21 or a non-insulated light source assembly 21, such as a non-isolated 7070 light source assembly 21, an insulated 3535 light source assembly 21, and the like.

[0042] Furthermore, the mounting portion 221 is provided with a clamping assembly for clamping the light source assembly 21. By providing the clamping assembly, the light source assembly 21 can be detachably connected to the mounting portion 221.

[0043] Preferably, a notch 2213 is provided in the middle of the mounting portion 221, and the light source assembly 21 is disposed in the notch 2213. The notch 2213 allows the light emitting components of the light source assembly 21 to be emitted through the notch 2213 toward the optical module 30. In addition, the notch 2213 can also dissipate heat from the light source assembly 21.

[0044] The snap-fit ​​assembly includes a first snap-fit ​​portion 2211 extending horizontally from the outer edge portion 222 toward the mounting portion 221 (notch 2213) and a second snap-fit ​​portion 2212 extending vertically from the mounting portion 221. The first snap-fit ​​portion 2211 and the second snap-fit ​​portion 2212 cooperate to limit the light source assembly 21 in the vertical direction.

[0045] Optionally, the first engaging portion 2211 is a support arm provided on the side of the outer edge portion 222 and extending toward the notch 2213, with an upwardly protruding hook provided at the end of the support arm. The second engaging portion 2212 is a protruding arm provided adjacent to the first engaging portion 2211 and extending in the vertical direction, with a hook provided at the top end of the protruding arm.

[0046] Furthermore, the projections of the first clamping portion 2211 and the second clamping portion 2212 on the horizontal plane deviate from each other and have a height difference in the vertical direction. This arrangement can make the first clamping portion 2211 and the second clamping portion 2212 have a certain elastic clamping effect, which can match a variety of light source assemblies 21 for clamping.

[0047] The outer edge portion 222 is disposed on the outer periphery of the mounting portion 221. The outer edge portion 222 is provided with a wire securing cavity 2221 for the power cord 23 to pass through. The wire securing cavity 2221 extends from the outer edge portion 222 in a direction away from the mounting portion 221. Furthermore, there is a height difference between the plane at the highest point of the wire securing cavity 2221 and the mounting portion 221. The wire securing cavity 2221 is configured to engage with the wire groove 114 on the housing. By providing a single wire securing cavity 2221, it can engage with both the power cord 23 and the housing, reducing the structure and saving costs.

[0048] Optionally, the cable fixing cavity 2221 includes a cable inlet 2226 and a cable outlet 2227 that are arranged opposite to each other, and the cross-sectional area of ​​the cable inlet 2226 is larger than the cross-sectional area of ​​the cable outlet 2227. In this arrangement, the power cord 23 enters the cable fixing cavity 2221 from the cable inlet 2226 and exits from the cable outlet 2227 to be electrically connected to the external mains.

[0049] The fixing cavity 2221 is provided with a clamping structure for clamping the power cord 23, and the clamping structure is configured to clamp and fix the power cord 23 in the fixing cavity 2221. In this way, the power cord 23 can be fixed in the fixing cavity 2221 to avoid being pulled and damaged.

[0050] In this embodiment, the snap-fit ​​structure includes an elastic snap-fit ​​portion 2224 and a snap-fit ​​ridge 2225 .

[0051] The elastic snap-on protrusion is an elastic snap-on protrusion disposed within the wire-fixing cavity 2221, wherein the snap-on protrusion faces the inner surface opposite the wire-fixing cavity 2221. Specifically, the snap-on ridge 2225 is disposed on the inner surface opposite the elastic snap-on portion 2224. This inner surface is provided with a plurality of snap-on ridges 2225 extending along the extension direction of the wire-fixing cavity 2221. The snap-on ridges 2225 and the elastic snap-on protrusion are arranged to secure the power cord 23 within the wire-fixing cavity 2221. Furthermore, due to the provision of the elastic snap-on protrusion, power cords 23 of different sizes can be snapped into the wire-fixing cavity 2221.

[0052] Furthermore, an extension portion 2228 is provided on the outside of the wire-fixing cavity 2221, extending away from the wire-fixing cavity 2221. The extension portion 2228 is configured to engage the wire-fixing cavity 2221 with the wire-passing groove 114. Since the volume of the wire-fixing cavity 2221 is smaller than that of the wire-passing groove 114, the extension portion 2228 is provided on the outside of the wire-fixing cavity 2221 to achieve the engaging engagement between the wire-fixing cavity 2221 and the wire-passing groove 114.

[0053] Furthermore, an inclined guide surface is provided on the extension portion 2228 to guide the wire fixing cavity 2221 into the wire groove 114 for clamping.

[0054] In order to achieve quick connection between the light source bracket 22 and the first shell 11, a first anti-fouling part 2222 for positioning and connecting with the first shell is further provided on the outer edge 222, and a second anti-fouling part 113 is further provided at the position of the first anti-fouling part 2222 of the first shell 11.

[0055] Among them, one of the first fool-proofing portion 2222 and the second fool-proofing portion 113 is a fool-proofing protrusion, and the other is a fool-proofing groove.

[0056] In this embodiment, the first foolproofing portion 2222 is a foolproofing protrusion provided on the light source bracket 22. This snap-fitting protrusion extends outward from the outer periphery of the outer edge portion 222 and extends toward the first housing 11. The second foolproofing portion 113 is a foolproofing groove provided on the mounting wall 111. Of course, in other embodiments, the first foolproofing portion 2222 can be a foolproofing groove, and the second foolproofing portion 113 can be a foolproofing protrusion. This application is not limited to this.

[0057] Furthermore, to improve the stability of the connection between the light source bracket 22 and the first housing, the outer edge 222 is further provided with a second mounting hole 2223 for fixing the light source bracket 22 to the housing. Correspondingly, a first mounting hole 116 is provided on the mounting wall. A fastener passes through the first mounting hole 116 and the second mounting hole 2223 to fix the light source bracket 22 to the first housing 11.

[0058] In particular, the fasteners are used to fix the light source bracket 22 and the light source assembly 21 to the mounting plate through the first mounting hole 116 and the second mounting hole 2223. The fasteners can be ST.* self-tapping screws and M* screws, wherein one ST.* screw is provided and three M* screws are provided. The ST.* screws are anti-pull screws to enhance the fixing effect with the light source bracket 22.

[0059] In this embodiment, the light source assembly 21 is non-insulated. Therefore, an insulating member 24 is interposed between the non-insulated light source assembly 21 and the mounting wall 111. Preferably, the insulating member 24 is an insulating, thermally conductive silicone sheeting interposed between the light source assembly 21 and the mounting wall 111. The insulating, thermally conductive silicone sheeting is disposed between the light source assembly 21 and the mounting wall 111 of the first housing 11.

[0060] The first positioning member 115 on the mounting wall 111 of the first housing 11 and the second positioning member 224 which is positioned and connected to the first positioning member 115 are correspondingly provided on the insulating member 24 .

[0061] Optionally, the first positioning member 115 is a positioning post extending from the mounting wall 111 into the mounting cavity 13. The second positioning member 224 is a positioning hole provided on the insulating thermally conductive silicone sheet, and the positioning post is engaged with the positioning hole to achieve a positioning connection between the mounting wall 111 and the insulating thermally conductive silicone sheet.

[0062] 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 second 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.

[0063] Since the insulating member 24 is sandwiched between the light source assembly 21 and the mounting wall 111 , a relief structure is provided on the insulating member 24 to prevent the light source bracket 22 from being blocked from being fixedly mounted on the mounting wall.

[0064] The avoidance structure includes an avoidance hole 241 and a giveway groove 242. The avoidance hole 241 is used to avoid the second mounting hole 2223 on the light source bracket 22, and the giveway groove 242 is used to avoid the wire fixing cavity 2221 on the light source bracket 22.

[0065] In other embodiments, the light source module 20 may also be an insulating light source module 20, that is, the insulating light source assembly 21 is detachably connected to the mounting portion 221 on the light source bracket 22. The insulating light source assembly 21 is fixedly connected to the light source bracket 22 by a snap-fit ​​structure on the mounting portion 221.

[0066] Since the insulating light source assembly 21 is clamped to the light source bracket 22, the first positioning member 115 may not be provided on the mounting wall 111 of the first housing 11. In other words, the first positioning member 115 is located in the gap of the insulating light source assembly 21 and does not affect the installation of the light source bracket 22.

[0067] The insulating light source assembly 21 directly abuts the mounting wall 111. The mounting wall 111 is provided with a second foolproof portion 113. The insulating external light source module 20 is correspondingly provided with a first foolproof portion 2222. The first foolproof portion 2222 is positioned and engaged with the second foolproof portion 113. The structures of the second foolproof portion 113 and the first foolproof portion 2222 are the same as those of the second embodiment and are not further described here.

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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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. A second docking portion 1238 is provided on the side of the first extension wall 123 facing the lip 124 to position and engage with the first docking portion 1123.

[0092] Optionally, one of the first docking portion 1123 and the second docking portion 1238 is a docking protrusion, and the other is a docking groove.

[0093] In this embodiment, the first docking portion 1123 is a docking protrusion that protrudes from the inner side of the connecting wall 112 into the mounting cavity 13. This docking protrusion is disconnected at the location of the snap-fit ​​groove to make way for the snap-fit ​​groove. Furthermore, a guide surface 1233 is provided on the side of the docking protrusion facing the second housing 12 to facilitate installation.

[0094] The second docking portion 1238 is a docking groove that is recessed from the outer side of the first extension wall 123 to the inner side. The docking groove is used for engaging with the docking protrusion for positioning.

[0095] Furthermore, the docking protrusion is arranged below the wire passing groove 114. Therefore, the insulating shell 212 is provided with a clearance groove 242 at a position corresponding to the docking protrusion. The clearance groove 242 is located below the first wire passing cavity.

[0096] Furthermore, the second housing 12 is further provided with a carrying portion 122 for carrying the optical component. The carrying portion 122 is recessed from the base 121 in a direction away from the first housing 11 , and is disposed around the light outlet 17 .

[0097] The supporting portion 122 includes a second extension wall 1221 extending away from the first housing 11 and a supporting wall 1222 extending from the second extension wall 1221 into the light outlet 17. Specifically, the supporting wall 1222 is located inside the second extension wall 1221 and is configured to abut against the optical module 30. The supporting wall 1222 is provided with a plurality of reinforcing ribs, with gaps between adjacent ribs, thereby forming a snap-fit ​​groove for snapping with a snap-fit ​​block on the second housing 12.

[0098] The second extension wall 1221 is provided with a first positioning engaging portion 1223 for positioning and engaging with the optical module 30. Optionally, the first positioning engaging portion 1223 is a positioning rib provided on the second extension wall 1221 of the bearing portion 122, and the positioning rib is positioned and engaged with a positioning groove on the optical module 30.

The mounting shaft 125 is positioned and snapped into the shaft recess 141, securing the second housing 12 and the third housing 14. Furthermore, because the mounting shaft 125 can rotate within the shaft recess 141, the second housing 12 can rotate relative to the third housing 14, thereby adjusting the light output direction of the lamp 100.

[0100] Furthermore, the inner side of the third shell 14 is configured as a trumpet-shaped light outlet channel, with the small opening being close to the second shell 12 and the large opening being close to the face ring 15 , so as to increase the light outlet area.

[0101] A notch 2213 is further defined between the third shell 14 and the second shell 12 , and the notch 2213 can assist in heat dissipation for the lamp 100 .

[0102] Furthermore, a face ring 15 is provided on a side of the third shell 14 away from the second shell 12 . A clip 16 is provided on the face ring 15 , and the lamp 100 is connected to the installation base via the clip 16 .

[0103] Furthermore, to improve the heat dissipation effect, a plurality of heat dissipation fins are provided on the side of the first shell 11 facing away from the mounting cavity 13.
