[0032] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all belong to the scope of protection of the present utility model. Each technical feature in the present utility model can be combined interactively on the premise of not conflicting with each other.

[0033] Referring to Figures 1 to 6 , an embodiment of the present utility model provides a modular downlight. With a modular design, it can solve the problem of difficult maintenance when some components of the downlight are damaged, reduce the maintenance cost of the downlight, and achieve a good heat dissipation function. While ensuring the use safety, it improves the economic benefits of the downlight.

[0034] The modular downlight includes a lamp holder 100, a light source module 200, and a driving module 300. Among them, the lamp holder 100 is provided with an installation cavity, the installation cavity is arranged with an opening facing downward, the upper wall surface of the installation cavity is a heat dissipation surface 130, and a locking member 140 is arranged above the heat dissipation surface 130. The light source module 200 is installed in the installation cavity, which can emit light, and the light irradiates from the lower end of the installation cavity to achieve the lighting function.

[0035] In this embodiment, the light source module 200 is detachably connected to the inner wall of the installation cavity. It is provided with a connecting member 230, the connecting member 230 extends upward and passes through the heat dissipation surface 130. The connecting member 230 is movably connected to the locking member 140. After the light source module 200 is locked to the lamp holder 100 through the locking member 140, the light source module 200 cannot be disengaged from below the installation cavity.

[0036] In this embodiment, the heat dissipation surface 130 is a metal surface. Of course, the heat dissipation surface 130 can also be made of other heat dissipation materials. In some embodiments, the entire lamp holder 100 is made of metal material, which has a good heat dissipation effect and is also easier to process. It can be understood that when the light source module 200 is locked to the lamp holder 100 through the locking member 140, the restrictive effect between the locking member 140 and the connecting member 230 can make the light source module 200 firmly contact the heat dissipation surface 130 to achieve a better heat dissipation effect.

[0037] The driving module 300 is arranged on the upper side of the heat dissipation surface 130 and is detachably connected to the lamp holder 100. The light source module 200 is provided with a jack 260, the jack 260 is arranged with an opening facing upward, and the driving module 300 is provided with a pin 350, the pin 350 extends downward. When the driving module 300 is installed on the lamp holder 100, the pin 350 passes through the heat dissipation surface 130 downward, the pin 350 extends into the installation cavity, and is inserted into the jack 260 of the light source module 200 to realize the conduction between the driving module 300 and the light source module 200.

[0038] Referring to Figure 5 and Figure 6 , in this embodiment, the pin 350 is a three - pin 350, and the jack 260 is a three - pin jack 260.

[0039] It can be understood that when one of the components of the lamp holder 100, light source module 200, and driving module 300 in the modular downlight is damaged, the damaged component can be directly removed and repaired or replaced, and the other components can continue to be used without being discarded, which greatly reduces maintenance costs and reduces waste of resources.

[0040] In some embodiments, reference Figure 3 , Figure 5 and Figure 7 The locking member 140 is a knob switch, which can be locked or separated with the connecting member 230 by rotating and pulling. Specifically, the locking member 140 is rotatably connected with the heat dissipation surface 130, and the locking member 140 is provided with an abutting groove 141, and the lower groove wall of the abutting groove 141 is provided with a notch 142. The upper end of the connecting member 230 is provided with an abutting block 231, and the abutting block 231 matches the notch 142. The abutting block 231 enters and exits the abutting groove 141 through the notch 142. When the abutting block 231 extends upward into the abutting groove 141, the lower end surface of the abutting block 231 can be rotatably connected with the lower groove wall of the abutting groove 141. When the locking member 140 is rotated to a position where the abutting block 231 and the notch 142 are staggered, the lower groove wall of the abutting groove 141 can limit the abutting block 231 from falling out downward, thereby achieving the locking between the connecting member 230 and the locking member 140. When the locking member 140 rotates to a position where the abutting block 231 corresponds to the notch 142 , the abutting block 231 can be disengaged downward from the abutting groove 141 , so that the connecting member 230 and the locking member 140 are separated, and the light source module 200 can be separated from the lamp holder 100 .

[0041] It is understandable that by rotating and pulling the locking piece 140 to achieve locking with the connecting piece 230, the light source module 200 can be connected to the lamp holder 100 while allowing the light source module 200 to contact the heat dissipation surface 130 more firmly, further improving the heat dissipation effect of the modular downlight.

[0042] In some embodiments, a locking platform 143 is provided on the lower groove wall of the abutment groove 141, and the locking platform 143 is protruded upward. When the locking member 140 rotates to the position where the abutment block 231 of the connecting member 230 abuts the locking platform 143, the locking member 140 can no longer rotate. At this time, the locking member 140 rotates to the position where the abutment block 231 and the notch 142 are in a completely staggered position. The locking member 140 can well lock the connecting member 230 to prevent the abutment block 231 from falling out of the abutment groove 141. It can be understood that the locking platform 143 can provide the operator with a reminder of locking in place, which is more conducive to the installation of the light source module 200.

[0043] In some embodiments, the lower groove wall of the abutting groove 141 is an inclined surface, which extends obliquely upward from the notch 142 towards the locking platform 143. With such a setting, during the process of locking the connecting member 230, the lower groove wall of the abutting groove 141 can guide the abutting block 231 of the connecting member 230 to move upward by a certain distance, so that the light source module 200 is closer to the heat dissipation surface 130, further improving the heat dissipation effect.

[0044] In some embodiments, the lower groove wall of the abutting groove 141 is provided with two notches 142 and two locking platforms 143, and the connecting member 230 is correspondingly provided with two abutting blocks 231. Each abutting block 231 is correspondingly arranged with a notch 142 and a locking platform 143, and the lower groove wall of the abutting groove 141 between the notch 142 and the locking platform 143 corresponding to the same abutting block 231 is an inclined surface. When the locking member 140 is rotated, the corresponding abutting block 231 moves on the corresponding inclined surface. When the light source module 200 needs to be disassembled, the locking member 140 is rotated to make the two abutting blocks 231 respectively correspond to the two notches 142; when the light source module 200 needs to be locked, the locking member 140 is rotated to make the two abutting blocks 231 respectively abut against the two corresponding locking platforms 143.

[0045] In some embodiments, the light source module 200 and the lamp holder 100 are connected by two locking members 140. Two connecting members 230 are arranged on the light source module 200, which can improve the connection stability between the light source module 200 and the lamp holder 100. Of course, the light source module 200 and the lamp holder 100 can also be connected by three, four or other numbers of locking members 140, and the number of the connecting members 230 is the same as the number of the locking members 140.

[0046] In some embodiments, referring to Figure 3 and Figure 4 , the lamp holder 100 includes a frame main body 110 and a middle shell 120. The installation cavity is arranged in the middle of the frame main body 110. The frame main body 110 is provided with a card slot, which opens upward and is located on the outer periphery of the installation cavity. The middle shell 120 is provided with an installation groove, which opens downward. The middle shell 120 is detachably connected to the frame main body 110. When the middle shell 120 is connected to the frame main body 110, the side wall of the middle shell 120 is clamped in the card slot, and the heat dissipation surface 130 is located in the installation groove.

[0047] In this embodiment, the frame main body 110 includes an outer frame and an inner frame. A convex platform protruding upward is arranged in the middle of the inner frame to form an installation cavity opening downward. The upper end surface of the convex platform is the heat dissipation surface 130. The outer frame is arranged on the outer periphery of the convex platform, and the lower end of the outer frame is connected to the inner frame. The outer peripheral wall surface of the convex platform and the inner side wall surface of the outer frame jointly form the above-mentioned card slot. It can be understood that the torsion springs for installing the modular downlight are installed on the left and right sides of the outer frame.

[0048] In this embodiment, the side wall of the middle housing 120 is provided with a sixth hook extending downward, and the side wall surface of the outer frame is provided with a hook hole. The sixth hook is matched with the hook hole, and the middle housing 120 and the outer frame are connected by the snap connection of the sixth hook and the hook hole.

[0049] The middle housing 120 is provided with a movable opening. The locking member 140 is detachably mounted on the upper side of the heat dissipation surface 130 and passes through the movable opening. A limiting platform 144 is provided at the lower end of the locking member 140, and the upper end of the limiting platform 144 abuts against the upper wall surface of the mounting groove, that is, the limiting platform 144 is arranged between the heat dissipation surface 130 and the upper wall surface of the mounting groove.

[0050] With such a setting, the locking member 140 can realize relative rotation with the heat dissipation surface 130, so as to realize the locking or separation of the connecting member 230. When the middle housing 120 is separated from the frame body 110, the locking member 140 can be separated from the frame body 110 and the middle housing 120, which is more beneficial to the processing and production of the locking member 140.

[0051] In some embodiments, the middle housing 120 is further provided with a disassembly and assembly opening, which is arranged at the edge of the movable opening and is communicated with the movable opening. A convex block 145 is provided on the outer side wall surface of the locking member 140, and the convex block 145 protrudes outward. The convex block 145 is matched with the disassembly and assembly opening. The upper surface of the middle housing 120 is provided with a first limiting block and a second limiting block, and the first limiting block and the second limiting block are respectively arranged outside the movable opening.

[0052] When the locking member 140 rotates to the position where the convex block 145 abuts against the first limiting block, the position of the convex block 145 corresponds to that of the disassembly and assembly opening, and the position of the abutting block 231 corresponds to that of the notch 142. The light source module 200 can be removed from the lamp holder 100, and when the frame body 110 is separated from the middle housing 120, the locking member 140 can also be separated from the middle housing 120. When the locking member 140 rotates to the position where the convex block 145 abuts against the second limiting block, the lower wall surface of the convex block 145 abuts against the upper wall surface of the middle housing 120, and the lower wall surface of the abutting block 231 abuts against the lower groove wall of the abutting groove 141. The light source module 200 is locked in the installation cavity, and the middle housing 120 can also be stably connected to the locking member 140.

[0053] In some embodiments, the lamp holder 100 is provided with a first hook 150, and the driving module 300 is provided with a housing 310. The inner side wall surface of the housing 310 is provided with a second hook 320. The detachable connection between the driving module 300 and the lamp holder 100 is realized by the snap connection between the first hook 150 and the second hook 320.

[0054] In some embodiments, the housing 310 is also provided with a pressing portion 330, which is arranged on the upper side of the second hook 320, and the inner side of the pressing portion 330 abuts against the outer side of the first hook 150. When the pressing portion 330 is pressed inward, the hook portion of the first hook 150 can move inward a certain distance, thereby separating the first hook 150 from the second hook 320. At this time, the operator pulls up the driving module 300 to achieve disassembly and separation between the driving module 300 and the lamp holder 100, which is simple and convenient to operate.

[0055] In some embodiments, the lamp holder 100 is also provided with an anti-foolproof plate 160, which is extended upward, and the housing 310 of the driving module 300 is provided with an anti-foolproof groove 340, which is opened downward. When connecting the lamp holder 100 and the driving module 300, the anti-foolproof plate 160 is aligned with the anti-foolproof groove 340, and the anti-foolproof plate 160 is inserted into the anti-foolproof groove 340.

[0056] It is understandable that the provision of the anti-foolproof plate 160 can play an anti-foolproof role, provide position prompts to operators during installation, and avoid relative rotation between the lamp holder 100 and the driving module 300 after installation.

[0057] In this embodiment, the anti-foolproof plate 160 and the first hook 150 are both disposed on the middle shell 120 .

[0058] In some embodiments, the light source module 200 includes a lens assembly 220 and a light source board 210 . The lens assembly 220 and the light source board 210 are detachably connected by snapping. The connector 230 is disposed on the lens assembly 220 and passes upward through the light source board 210 .

[0059] In this way, when one of the light source board 210 or the lens assembly 220 is damaged, only the damaged structure needs to be replaced, and the undamaged structure can continue to be used, further reducing waste and lowering maintenance costs. In addition, the light source board 210 is directly buckled and installed on the lens assembly 220, which is convenient and quick to disassemble and assemble.

[0060] Specifically, a bayonet is provided at the edge of the light source board 210, and a third hook 240 is provided at the lens assembly 220. The third hook 240 is extended upward and is engaged with the bayonet of the light source board 210. Clearance holes are provided on the heat dissipation surface 130 and the upper wall surface of the installation groove. The upper end of the third hook 240 passes upward through the clearance hole. When the light source module 200 is installed, the light source board 210 can contact the heat dissipation surface 130 to achieve a good heat dissipation effect.

[0061] In this embodiment, two third hooks 240 are provided on the lens assembly 220, which can improve the connection stability between the lens assembly 220 and the light source board 210.

[0062] It can be understood that the jack 260 is provided on the light source board 210. When the pin 350 of the driving module 300 is inserted into the jack 260, the driving module 300 is electrically connected to the light source board 210, so that the light source board 210 can be driven by the driving module 300.

[0063] It can be understood that the light source board 210 is the light-emitting component of the modular downlight. In some embodiments, the light source board 210 has light effects of multiple powers and multiple color temperatures, and the driving module 300 can control the light source board 210 to emit light of different powers or different color temperatures.

[0064] Referring to Figure 4 and Figure 5 , in some embodiments, the lamp holder 100 is further provided with an anti-fooling post 170. The anti-fooling post 170 penetrates through the heat dissipation surface 130 and extends downward. The light source module 200 is provided with an anti-fooling hole 250, and the anti-fooling hole 250 matches the anti-fooling post 170. When the light source module 200 is connected to the lamp holder 100, the anti-fooling post 170 is inserted into the anti-fooling hole 250. In this embodiment, the anti-fooling post 170 is connected to the upper wall surface of the installation groove.

[0065] It can be understood that the anti-fooling post 170 can provide a position prompt for the operator during the installation of the light source module 200 and the lamp holder 100, so as to ensure the accurate installation position between the light source module 200 and the lamp holder 100, and it is not easy to have drawbacks during the disassembly and assembly process, improving the convenience of disassembly and assembly, so that the pin 350 of the driving module 300 and the jack 260 of the light source module 200 can correspond to each other and be electrically connected.

[0066] In some embodiments, the modular downlight further includes a face cover 400. The face cover 400 is detachably connected to the lower end of the lamp holder 100 and abuts against the lower end of the light source module 200. It can be understood that, with such a setting, the face cover 400 can provide support for the lower end of the light source module 200 and can block the gap between the light source module 200 and the inner wall of the installation cavity, improving the safety performance of the modular downlight.

[0067] It can be understood that the detachable connection between the face cover 400 and the lamp holder 100 is beneficial to the disassembly and assembly of the light source module 200 and also beneficial to the replacement of the face cover 400.

[0068] In some embodiments, the face cover 400 is provided with a fourth hook 410 extending upward, and the lamp holder 100 is provided with a fifth hook 180. The face cover 400 and the lamp holder 100 are detachably connected by the engagement between the fourth hook 410 and the fifth hook 180.

[0069] In this embodiment, the fifth hook 180 is arranged at the lower end of the middle shell 120. A through hole is arranged on the lower end surface of the lamp holder main body 110. The through hole is communicated with the card slot. The fourth hook 410 passes through the through hole and extends into the card slot, and is clamped with the fifth hook 180, which can realize the detachable connection between the face cover 400 and the lamp holder 100 while preventing the face cover 400 from rotating relative to the lamp holder 100.

[0070] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
