[0002] Currently, when installing a lamp, it is necessary to first install a chassis on an installation base including a ceiling, then install a power module and a light source module on the chassis respectively, and then perform circuit wiring and cover the lamp shade.

[0003] This installation method requires users to spend a long time to complete the lamp installation. For example, users need to lift their arms with both hands for a long time to electrically connect the power module to the power supply on the chassis, that is, the installation, repair or disassembly process of the lamp is time-consuming and laborious. Moreover, during the installation process, it is necessary to perform circumferential alignment before the next connection action, and the docking surfaces of the two are often face-to-face. When the user connects the two, since the docking surface cannot be visually seen, it is necessary to repeatedly try to complete the alignment of the two, resulting in low installation efficiency.

[0004] In view of this, it is indeed necessary to improve the existing lamp mounting structure to solve the above problems. Summary of the Invention

The two contact parts are respectively formed by extending in the same direction from the second fixing arm and the third fixing arm.

[0010] As a further improvement of the present invention, the electrical connection part further includes a guiding part connected to the contact part. There are at least two pairs of the guiding parts, which are used to guide the second connector of the lamp into the clamping space along different directions to be in electrical contact with the contact part.

[0011] As a further improvement of the present invention, the insulating body includes a first body and a second body assembled and fixed in the up-down direction, and the slot is formed in both the first body and the second body at the same time.

[0012] To achieve the above object, the present invention further provides a second connector, which can be connected to the lamp body and is electrically connected to the foregoing first connector in a matching manner. The second connector includes a base and an electrical cooperation part received in the base.

[0053] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] As Figures 1 to 3 shown, the present invention discloses a lamp 100, including a lamp installation structure composed of a fixing base 10 and a connecting base 20, a driving module 30 fixed on the connecting base 20, a light source module 40 electrically connected to the driving module 30, and a frame assembly 50 and a mask 60 assembled and fixed to the connecting base 20. Among them, the fixing base 10 is configured to be mechanically and electrically connected to the installation base, and at the same time is configured to be matched with the connecting base 20 to achieve mechanical and electrical connection; the driving module 30 is configured to supply power to the light source module 40 and drive the light source module 40; the mask 60 is configured to emit the light emitted by the light source module 40 from the mask 60, so as to light up the surrounding environment.

[0055] The lamp 100 of the present invention is preferably a rectangular ceiling lamp installed on the ceiling. Correspondingly, the fixing base 10, the connecting base 20, the frame assembly 50 and the mask 60 are also correspondingly set to be rectangular. Of course, the lamp 100 of the present invention can also be a circular ceiling lamp or a ceiling lamp of other shapes. At this time, only the shapes and specific structures of the fixing base 10, the connecting base 20, the frame assembly 50 and the mask 60 need to be adjusted accordingly. For the convenience of description, the following description in the specification will take the rectangular ceiling lamp as an example, but it should not be limited thereto.

[0056] As Figures 4 to 7 and in combination with Figure 2 shown, the fixing base 10 is arranged in a rectangular shape, including two long sides 11 arranged oppositely and two short sides 12 arranged oppositely. Installation holes 101 are provided at the four corners of the fixing base 10 so that screws (not shown) can pass through the installation holes 101 to fix the fixing base 10 to the ceiling. An opening 13 is formed by enclosing the two long sides 11 and the two short sides 12 of the fixing base 10. The opening 13 can not only facilitate the installation of the fixing base 10 to the ceiling, but also facilitate the assembly between the fixing base 10 and the connecting base 20. A wiring terminal assembly 14 is provided on one of the long sides 11. On the one hand, the wiring terminal assembly 14 is connected to the wire pre-buried in the ceiling, and on the other hand, it is electrically connected to the first connector 17 described below. Thus, the driving module 30 can be powered on by the electrical connection between the first connector 17 and the second connector 24, and the electrical connection between the second connector 24 and the driving module 30.

[0057] The wiring terminal assembly 14 includes a body 141 and at least two terminals (not shown) received in the body 141. Two of the terminals respectively correspond to the positive and negative poles of the pre-buried wire, so as to realize the electrical connection between the wiring terminal assembly 14 and the pre-buried wire. In a preferred embodiment of the present invention, there are 3 terminals, namely a positive terminal, a negative terminal and a grounding terminal. When connecting, directly insert the pre-buried wire into the jack 142 of the body 141 to make electrical connection with the terminal received in the jack 142 of the body 141. Of course, in other embodiments of the present invention, the wiring terminal assembly 14 may not be provided, and the first connector 17 is directly electrically connected to the pre-buried wire, and then the driving module 30 is powered on by the electrical connection between the first connector 17 and the second connector 24, and the electrical connection between the second connector 24 and the driving module 30.

[0058] The connecting seat 20 is also rectangularly arranged and is provided with a mechanical connecting portion to be mechanically connected to the two short sides 12 of the fixed seat 10. Specifically, the mechanical connecting portion includes a rotating member 21 fixed to the connecting seat 20 and rotatable relative to the connecting seat 20, and a sliding assembly 22 fixed to the connecting seat 20 and displaceable relative to the connecting seat 20 in the horizontal direction. Among them, the rotating member 21 is configured to connect the connecting seat 20 and the fixed seat 10, and the connecting seat 20 can move toward the fixed seat 10, and the sliding assembly 22 is configured to be slidably connected to the fixed seat 10 so that the connecting seat 20 is fixed to the ceiling through the fixed seat 10.

[0059] In the present invention, the rotating member 21 is a rotating handle arranged in a U shape. The rotating handle 21 includes a first rod 211 and a second rod 212 arranged oppositely, and a third rod 213 connecting the first rod 211 and the second rod 212. The end of the first rod 211 is bent to form a first fixing rod 214, and the end of the second rod 212 is bent to form a second fixing rod 215, and the first fixing rod 214 and the second fixing rod 215 are arranged oppositely. Correspondingly, two connecting members 23 are provided on the connecting seat 20, and a connecting hole 231 is formed in each connecting member 23. The first fixing rod 214 and the second fixing rod 215 respectively pass through the corresponding connecting holes 231 and are snap-connected to the connecting members 23. At the same time, the first fixing rod 214 and the second fixing rod 215 can also rotate in the corresponding connecting holes 231. Because the rotating handle 21 is a U-shaped rod structure, during installation, the first rod 211 and the second rod 212 can be directly pulled to insert the first fixing rod 214 and the second fixing rod 215 into the corresponding connecting holes 231 and be bent and fixed to the corresponding connecting members 23. At this time, the installation of the rotating handle 21 is completed. After the installation is completed, the overall rotation of the rotating handle 21 can be driven by the rotation of the first fixing rod 214 and the second fixing rod 215 in the corresponding connecting holes 231.

[0060] The fixed seat 10 is provided with a fixing member 15, and the rotating handle 21 is snap-connected to the fixing member 15 so as to suspend and connect the connecting seat 20 and the fixed seat 10 through the rotating handle 21. Specifically, a fixing groove 151 is provided in the fixing member 15, and the third rod 213 of the rotating handle 21 is limited in the fixing groove 151. A positioning member 16 is further provided on the fixed seat 10. One end of the positioning member 16 is rotatably connected to the fixing member 15, and the other end is configured to be rotatable. A positioning groove 161 is provided in the positioning member 16 so that the third rod 213 of the rotating handle 21 can be limited in the fixing groove 151 and the positioning groove 161 at the same time.

[0061] Specifically, the fixing member 15 and the fixing base 10 are integrally formed. The fixing groove 151 is open-ended to facilitate the third rod 213 to enter the fixing groove 151. One end of the positioning member 16 is connected to the fixing member 15 through a rotating shaft (not shown), and the other end is a free end for cooperating to fix the third rod 213. A hook 162 is provided at the other end of the positioning member 16. The hook 162 is used to cooperate with the positioning groove 161 to jointly fix the third rod 213 of the rotary handle 21. After the third rod 213 of the rotary handle 21 enters the fixing groove 151, the third rod 213 can be simultaneously limited in the positioning groove 161 by rotating the positioning member 16, realizing the limit fixation of the third rod 213.

[0062] In the present invention, the fixing member 15 is formed on the inner sides of the two long sides 11. Two positioning members 16 are provided to respectively fix the two ends of the third rod 213 of the rotary handle 21. Of course, the fixing member 15 can also be assembled and fixed to the fixing base 10, and the number of the positioning member 16 and the fixing member 15 can also be set to one each, directly fixing the middle part of the third rod 213.

[0063] As Figures 8 to 11 and in combination with Figure 5 with Figure 6 shown, the sliding assembly 22 includes a positioning portion 221 provided near the edge of the short side 12 of the fixing base 10. A mating portion 121 is correspondingly provided on the short side 12. When the sliding assembly 22 is mechanically connected to the fixing base 10, the positioning portion 221 and the mating portion 121 are mutually limited and fixed. Preferably, the positioning portion 221 is a slider having an inclined guiding surface 222, and the mating portion 121 is a slot provided on the short side 12. The slider 221 is adapted to extend into or out of the slot 121. For example, when the sliding assembly 22 is mechanically connected to the fixing base 10, the slider 221 slides into the slot 121 under the guidance of its guiding surface 222 and is snap-connected to the inner wall surface of the slot 121.

[0064] The sliding assembly 22 further includes an upper cover 223 and a lower cover 224 assembled and mated in the vertical direction, and a sliding member 226 and an elastic member 227 received in a receiving space (not labeled) formed by the upper cover 223 and the lower cover 224. The slider 221 is provided on the sliding member 226 and exposed outside the upper cover 223 and the lower cover 224, that is, exposed to the receiving space 225 mentioned below. One end of the elastic member 227 is connected to the sliding member 226, and the other end is connected to the inner side wall of the lower cover 224. Thus, when the slider 221 is squeezed, the sliding member 226 can slide into the receiving space and push the elastic member 227 to compress the elastic member 227, and the slider 221 slides out of the slot 121; after the slider 221 is released, the elastic member 227 can push the sliding member 226 to reset, so that the slider 221 extends into the slot 121 and returns to be exposed to the receiving space 225.

[0065] Preferably, the slider 221 and the sliding member 226 of the present invention are integrally provided. On the one hand, it is convenient for injection molding. On the other hand, the cooperation stability between the sliding member 226 and the slider 221 is optimal. Of course, the sliding member 226 and the slider 221 can also be assembled and fixed while ensuring better stability between the sliding member 226 and the slider 221, and there is no limitation here.

[0066] To ensure the working stability of the elastic member 227, a first positioning post 2261 is provided on the sliding member 226, and the first positioning post 2261 and the slider 221 are oppositely arranged at both ends of the sliding member 226. A second positioning post 2241 is provided on the inner side wall of the lower cover 224. The elastic member 227 of the present invention is preferably a spring. One end of the spring 227 is sleeved on the first positioning post 2261 and abuts against the sliding member 226, and the other end is sleeved on the second positioning post 2241 and abuts against the inner side wall of the lower cover 224; the numbers of the spring 227, the first positioning post 2261, and the second positioning post 2241 are all set to two. With such a setting, it can be ensured that the sliding member 226 can stably push the spring 227, and the sliding member 226 will not be offset due to the resistance of the spring 227.

[0067] Further, the sliding member 226 includes a main body portion 2262 received in the receiving space and a connecting portion 2263 connected to the main body portion 2262 on one side of the slider 221. The slider 221 is connected to one end of the main body portion 2262, and the first positioning post 2261 is provided at the other end of the main body portion 2262. The connecting portion 2263 is arranged in a U shape and includes a first connecting arm 2264 connected to the main body portion 2262, a second connecting arm 2265 oppositely arranged to the first connecting arm 2264, and a third connecting arm 2266 connecting the first connecting arm 2264 and the second connecting arm 2265. Among them, the slider 221 is connected to the first connecting arm 2264 and protrudes towards the second connecting arm 2265, and the third connecting arm 2266 is located below the slider 221 and a positioning space 2267 is formed between the third connecting arm 2266 and the slider 221.

[0068] Correspondingly, an abutting portion 122 is further provided on one side of the fixed seat 10 close to the slider 221. The abutting portion 122 is located below the slot 121 and connected to the slot 121. Thus, after the slider 221 slides into the slot 121, the abutting portion 122 can be received in the positioning space 2267, and the slider 221 abuts against the abutting portion 122. A blocking portion 123 connected to the abutting portion 122 is further provided on the short side 12 of the fixed seat 10. Both the abutting portion 122 and the blocking portion 123 are plate-shaped. The abutting portion 122 is connected to the bottom edge of the short side 12 in the horizontal direction, and the blocking portion 123 is perpendicular to the abutting portion 122 in the vertical direction, so that the abutting portion 122, the blocking portion 123 and the short side 12 of the fixed seat 10 jointly define a blocking groove 124. When the slider 221 slides into the slot 121, it will be received in the blocking groove 124 and abut against the abutting portion 122.

[0069] The sliding assembly 22 further includes a reinforcing member 228, and the reinforcing member 228 is fixedly connected to one side of the sliding member 226 close to the lower cover 224. Specifically, the reinforcing member 228 is plate-shaped and covers the bottoms of the main body portion 2262 and the slider 221 to enhance the structural strength of the sliding member 226. In the present invention, the reinforcing member 228 is fixedly connected to the main body portion 2262 by screwing with a screw 80; of course, the reinforcing member 228 can also be fixed to the main body portion 2262 by means of a buckle, adhesion or welding.

[0070] The sliding assembly 22 further includes a pressing plate 229 fixedly connected to the lower cover 224 in the up and down direction. The pressing plate 229 is in an inverted U shape to form a limiting space 2291 between the pressing plate 229 and the lower cover 224. The main body portion 2262 of the sliding member 226 is received in the limiting space 2291 and can slide in the limiting space 2291. In the present invention, the pressing plate 229 and the lower cover 224 are locked and fixed by a fastener, and the fastener is preferably a screw; of course, the pressing plate 229 can also be fixed to the lower cover 224 by means of a buckle, adhesion or welding. The setting of the pressing plate 229 further enhances the structural strength of the sliding assembly 22, ensuring that the connecting seat 20 can be stably fixed on the fixed seat 10 and will not easily fall off.

[0071] The upper cover 223 covers above the pressing plate 229 and is snap-fixed to the lower cover 224. A shielding portion 2231 for shielding the first connecting arm 2264 is further provided on one side of the upper cover 223 close to the slider 221. In addition to playing a shielding role, the shielding portion 2231 can also limit the excessive reset of the first connecting arm 2264 when the spring 227 pushes the slider 221 to reset, playing a role in protecting the spring 227 and limiting the sliding member 226. The lower cover 224 is provided with a fixing portion 2242 corresponding to the connecting portion 2263, and the fixing portion 2242 is screwed and fixed to the connecting seat 20 by screws. An accommodating space 225 is formed between the upper cover 223 and the fixing portion 2242. The slider 221 is exposed in the accommodating space 225, and the abutting portion 122 and the blocking portion 123 of the fixing seat 10 are both received in the accommodating space 225, making the assembly and cooperation between the fixing seat 10 and the sliding assembly 22 more convenient.

[0072] To ensure the installation stability between the fixing seat 10 and the connecting seat 20, two relatively arranged sliding assemblies 22 are provided on the connecting seat 20 to be fixedly connected to the two short sides 12 of the fixing seat 10 respectively.

[0073] All in all, the mechanical connection between the fixing seat 10 and the connecting seat 20 is mainly achieved through the snap-fit between the rotary handle 21 and the fixing member 15 and the positioning member 16, and the insertion and extraction fit between the sliding assembly 22 and the slot 121.

[0074] Next, the electrical connection structure and the electrical connection principle between the fixing seat 10 and the connecting seat 20 will be mainly described.

[0075] Such as Figure 4 And Figure 5As shown, the fixed seat 10 is provided with a first connector 17, and the connection seat 20 is provided with a second connector 24. The first connector 17 is connected to the wiring terminal assembly 14 through an electric wire. The second connector 24 is configured to be electrically connected to the first connector 17 so that the connection seat 20 is electrically connected to the fixed seat 10. Preferably, the rotating member 21, the sliding assembly 22 and the second connector 24 are all arranged on the same surface of the connection seat 20. There are at least two sliding assemblies 22, and two of them are respectively arranged at the opposite ends of the connection seat 20 to ensure that the connection seat 20 can be stably mounted on the fixed seat 10. The second connector 24 is arranged close to one of the sliding assemblies 22. Of course, there can also be only one sliding assembly 22 and one second connector 24. At this time, the sliding assembly 22 and the second connector 24 can be respectively arranged at the opposite ends of the connection seat 20. Through the plug-in cooperation between the second connector 24 and the first connector 17 and the sliding connection between the sliding assembly 22 and the fixed seat 10, the stable connection between the fixed seat 10 and the connection seat 20 can also be realized. In this embodiment, there are two sliding assemblies 22 which are respectively arranged on the two long sides of the connection seat 20, and the second connector 24 is arranged close to one of the sliding assemblies 22.

[0076] As Figures 12 to 17 shown, the first connector 17 includes an insulating body 171 and an electrical connection portion 172 received in the insulating body 171. The insulating body 171 is provided with a slot 1710, and at least part of the electrical connection portion 172 is exposed to the slot 1710 so that the second connector 24 can be inserted into the slot 1710 to make electrical contact with the electrical connection portion 172. In the present invention, since the fixed seat 10 and the connection seat 20 are assembled in the up and down direction, the slot 1710 is configured to open towards at least two different directions so that the second connector 24 can be inserted into the slot 1710 along different directions to be electrically connected to the first connector 17. Preferably, the insulating body 171 includes a first body 1711 and a second body 1712 assembled and fixed in the up and down direction, and the slot 1710 is simultaneously provided in the first body 1711 and the second body 1712, so that the second connector 24 can be inserted into the slot 1710 in the up and down direction and the left and right direction perpendicular to the up and down direction.

[0077] Specifically, a receiving cavity 1713 for receiving the electrical connection part 172 and a first fixing post 1714 protruding into the receiving cavity 1713 are formed in the first body 1711. A first limiting groove 1715 is formed in the first fixing post 1714, and positioning plates 1716 are arranged on both sides of the first fixing post 1714. The slot 1710 communicates with the receiving cavity 1713, and the slot 1710 opens in the left-right direction on the first body 1711. Here, the left-right direction is the long side direction of the fixing base 10. A limiting part 1717 is also arranged on one side of the slot 1710 of the first body 1711, and this limiting part 1717 is used to prevent the electrical connection part 172 from detaching from the receiving cavity 1713.

[0078] A clamping block 1718 is arranged on the outer side wall of the first body 1711, and a clamping groove 1719 is correspondingly arranged on the inner side wall of the second body 1712. Thus, by means of the mutual cooperation of the clamping block 1718 and the clamping groove 1719, the snap-fastening fixation of the first body 1711 and the second body 1712 can be realized. A convex post 173 protrudes from the bottom inner side wall of the second body 1712. When the first body 1711 and the second body 1712 are assembled and fixed, the convex post 173 is inserted into the first limiting groove 1715 to achieve the positioning of the first body 1711 and the second body 1712. The slot 1710 opens in the up-down direction on the second body 1712. Here, the up-down direction is the assembling direction of the fixing base 10 and the connecting base 20. After the first body 1711 and the second body 1712 are assembled and fixed, the slot 1710 opens in both the up-down direction and the left-right direction. Thus, the second connector 24 can be inserted into the slot 1710 in the up-down direction or the left-right direction to achieve electrical connection with the electrical connection part 172.

[0079] A limiting strip 174 protrudes from the bottom inner side wall of the second body 1712, and this limiting strip 174 is located beside the slot 1710. Hanging ears 175 are arranged on both outer side walls of the second body 1712. Each hanging ear 175 is provided with a convex platform 1751 and a screw hole 1752. The convex platform 1751 is used to pass through a corresponding first through hole 18 on the fixing base 10 to achieve the positioning connection of the hanging ear 175 and the fixing base 10. The screw hole 1752 is used to cooperate with a corresponding second through hole 19 on the fixing base 10 so that a screw passes through the second through hole 19 and is threadedly connected with the screw hole 1752 to achieve the locking and fixing of the hanging ear 175 and the fixing base 10, and further fix the first connector 17 on the fixing base 10.

[0080] The electrical connection part 172 includes a fixing part 1721 and a contact part 1722 connected to the fixing part 1721. The fixing part 1721 is fixed in the receiving cavity 1713 of the first body 1711, and the contact part 1722 extends from the fixing part 1721 to be exposed in the slot 1710. Preferably, the fixing part 1721 is arranged in a U shape and includes a first fixing arm 1723 extending horizontally, and a second fixing arm 1724 and a third fixing arm 1725 arranged perpendicular to the first fixing arm 1723. A relief hole 1726 is formed in the first fixing arm 1723, and the relief hole 1726 is arranged in alignment with the first limiting groove 1715, so that the convex column 173 in the second body 1712 can pass through the relief hole 1726 and be inserted and fixed with the first limiting groove 1715 to realize the positioning of the electrical connection part 172. Notches 1727 are recessed at the tops of the second fixing arm 1724 and the third fixing arm 1725, and the notches 1727 are used for being inserted and fixed with the positioning plate 1716, thereby realizing the further positioning of the electrical connection part 172.

[0081] The contact parts 1722 are arranged in pairs, and the two contact parts 1722 are respectively formed by extending in the same direction from the second fixing arm 1724 and the third fixing arm 1725. The two contact parts 1722 are close to each other to form a clamping space 1728 between the two contact parts 1722. The electrical connection part 172 further includes a guiding part 176 connected to the contact part 1722, and the guiding part 176 is used for guiding the electrical mating part 242 of the second connector 24 into the clamping space 1728 to be in electrical contact with the contact part 1722. Since the slot 1710 in the present invention opens in both the up-down direction and the left-right direction at the same time, two pairs of guiding parts 176 are provided to guide the second connector 24 into the clamping space 1728 to be in electrical contact with the contact part 1722 along different directions.

[0082] Specifically, one pair of guiding parts 176 is integrally formed with the contact part 1722 and extends outward from the contact part 1722 to at least partially contact the limiting part 1717. On the one hand, it can prevent the electrical connection part 172 from detaching from the slot 1710 when the first connector 17 and the second connector 24 are inserted and pulled out in the left-right direction. On the other hand, it can also well guide the second connector 24 into the clamping space 1728 in the left-right direction, so that the insertion of the first connector 17 and the second connector 24 is smooth. The other pair of guiding parts 176 extends downward from the bottom of the contact part 1722 to at least partially contact the limiting strip 174. On the one hand, it can prevent the electrical connection part 172 from detaching from the slot 1710 when the first connector 17 and the second connector 24 are inserted and pulled out in the up-down direction. On the other hand, it can also well guide the second connector 24 into the clamping space 1728 in the up-down direction, so that the insertion of the first connector 17 and the second connector 24 is smooth.

[0083] Such as Figures 18 to 21and in combination with Figures 12 to 17 As shown, the second connector 24 includes a base 241 and an electrical mating part 242 received in the base 241. The electrical mating part 242 extends beyond the base 241 and is configured to be inserted into the slot 1710 of the first connector 17 to make electrical contact with the electrical connection part 172, so that the first connector 17 and the second connector 24 are matched and electrically connected. Specifically, the base 241 includes a first base 2411 and a second base 2412 assembled and fixed in the up and down direction. An accommodation cavity 2413 for accommodating the second base 2412 and an accommodation groove 2414 recessed in the inner side wall of the first base 2411 for accommodating the electrical mating part 242 are formed in the first base 2411. The accommodation groove 2414 communicates with the accommodation cavity 2413. A bump 2415 is provided in the accommodation groove 2414.

[0084] Second fixing posts 2416 are further provided on the inner side wall of the first base 2411. Second limiting grooves 2417 are formed in the second fixing posts 2416. A third through hole 2418 is provided at the bottom of the second base 2412. Thus, an external fixing member can pass through the third through hole 2418 and the second limiting groove 2417 to fixedly connect the first base 2411 and the second base 2412. A limiting plate 2419 is provided on the inner bottom side wall of the second base 2412. Similar to the fixing manner of the first body 1711 and the second body 1712, the first base 2411 and the second base 2412 are also snap-fixed by means of the cooperation of a snap block and a snap groove, which will not be described in detail here.

[0085] The electrical mating part 242 is configured as a pin structure and inserted into the clamping space 1728 to make electrical contact with the electrical connection part 172. First grooves 2421 are recessed on both the upper and lower sides of the electrical mating part 242. Among them, one side of the first groove 2421 is used for limiting cooperation with the bump 2415 in the first base 2411, and the other side of the first groove 2421 is used for limiting cooperation with the limiting plate 2419 in the second base 2412, so as to limit the electrical mating part 242 between the first base 2411 and the second base 2412 and realize the fixation of the electrical mating part 242. A third positioning post 243 is provided on the outer bottom side wall of the second base 2412. The third positioning post 243 is used for cooperating with the connection seat 20 to fix the second connector 24 on the connection seat 20.

[0086] All in all, the electrical connection between the fixing seat 10 and the connection seat 20 is mainly realized through the plug-in cooperation of the first connector 17 and the second connector 24. The power transmission path for supplying power to the lamp is: mains power → terminal block assembly 14 → first connector 17 → second connector 24 → drive module 30 → light source module 40, and finally the lamp beads are lit to achieve the lighting effect.

[0087] AsFigure 22 and in combination with Figure 3 As shown, both the driving module 30 and the light source module 40 are fixed to one side of the connecting seat 20 facing away from the fixing seat 10. In the present invention, the driving module 30 is fixed at the middle position of the connecting seat 20 and is electrically connected to the second connector 24; the light source module 40 is disposed around the driving module 30 and is electrically connected to the driving module 30, so that the driving module 30 supplies power to the light source module 40 and drives the light source module 40. The light source module 40 includes a light source board 41, lamp beads (not shown) fixed on the light source board 41, and a lens 42. The light source board 41 is electrically connected to the driving module 30 to light up the lamp beads, and the lens 42 covers the outside of the lamp beads to uniformly emit light. The specific structure of the driving module 30 and the specific connection manner between the driving module 30 and the light source module 40 can both adopt existing technical solutions, so they will not be described in detail here.

[0088] As Figures 23 to 32 and in combination with Figure 3 As shown, one end of the frame assembly 50 is disposed around the outside of the light source module 40 and is fixedly connected to the connecting seat 20, and the other end is connected to the mask 60 through a fixing member 70, so as to accommodate the light source module 40 between the connecting seat 20 and the mask 60, so that the light emitted by the light source module 40 can pass through the mask 60 and be emitted outward. In the present invention, the frame assembly 50 is fixedly connected to the connecting seat 20 by screwing. Of course, the frame assembly 50 can also be assembled and fixed to the connecting seat 20 by means of clamping, adhesion, etc.

[0089] The frame assembly 50 is formed by connecting a plurality of frames 51 and a plurality of corner frames 52 end to end. Specifically, there are four frames 51 and four corner frames 52 respectively. The corner frames 52 are arc-shaped and are respectively connected to two adjacent frames 51 at both ends, so that the frames 51 and the corner frames 52 jointly enclose to form an annular frame assembly 50.

[0090] The frame 51 includes a first side plate 511, a second side plate 512 disposed opposite to the first side plate 511, a first mounting plate 513 connecting the first side plate 511 and the second side plate 512, and a second mounting plate 514 connecting the first side plate 511 and the second side plate 512 and disposed opposite to the first mounting plate 513. Among them, the first mounting plate 513 and the second mounting plate 514 are arranged in parallel with each other. Both ends of the first mounting plate 513 are respectively connected to the first side plate 511 and the second side plate 512, and both ends of the second mounting plate 514 are also respectively connected to the first side plate 511 and the second side plate 512, so that the first side plate 511, the second side plate 512, the first mounting plate 513, and the second mounting plate 514 jointly enclose to form a slot 515. When connecting, both ends of the corner frame 52 are respectively matched with the slots 515 of the adjacent frames 51 to connect two adjacent frames 51.

[0091] A second groove 5121 is formed on the second side plate 512. Specifically, the second side plate 512 is recessed towards the first side plate 511 at a position close to the first mounting plate 513 to form the second groove 5121; of course, in other embodiments, the second groove 5121 can also be provided at other positions on the second side plate 512, which is not limited herein. A third groove 5141 is formed on the second mounting plate 514, and the third groove 5141 is used to cooperate with the connecting seat 20 so that the connecting seat 20 is screwed and fixed to the frame 51.

[0092] The corner frame 52 includes a plug-in portion 521 and a corner portion 522. The corner portion 522 is arc-shaped. There are two plug-in portions 521 which are respectively connected to both ends of the corner portion 522. During connection, the two plug-in portions 521 are respectively matched with the slots 515 of the two frames 51 to realize the connection of two adjacent frames 51. The shape and size of the plug-in portion 521 match the shape and size of the slot 515 so that the plug-in portion 521 can be received in the slot 515 and contact the inner side wall of the slot 515. An installation opening 523 is provided on the plug-in portion 521, and the position of the installation opening 523 corresponds to the position of the third groove 5141. Thus, when the plug-in portion 521 is received in the slot 515, the frame 51 and the corner frame 52 can be fixedly connected by passing a fastener through the third groove 5141 and locking it with the installation opening 523.

[0093] A contact surface 5221 is provided on the corner portion 522. Specifically, the contact surface 5221 is provided on the inner side of the corner portion 522 and close to the plug-in portion 521. When the plug-in portion 521 is received in the slot 515, the second side plate 512 abuts against the connection between the corner portion 522 and the plug-in portion 521, and the contact surface 5221 is flush with the second side plate 512. The outer side wall of the corner portion 522 has the same shape and size as the first side plate 511, and the outer side wall surface of the corner portion 522 is flush with the outer side wall surface of the first side plate 511 to realize the flatness and unity of the outer side wall surface of the frame assembly 50.

[0094] The mask 60 is connected to the frame assembly 50 by a fixing member 70. Specifically, the fixing member 70 is L-shaped and includes a first fixing plate 71 parallel to the second side plate 512 and a second fixing plate 72 connected to the first fixing plate 71. Both the first fixing plate 71 and the second fixing plate 72 are flat plates, and of course, they can also be set to be curved. Preferably, the second fixing plate 72 is perpendicular to the first fixing plate 71. Of course, an acute angle or an obtuse angle can also be formed between the first fixing plate 71 and the second fixing plate 72.

[0095] The first fixing plate 71 is provided with a positioning piece 711, a reinforcing rib 712 and a fixing hole 713. Specifically, the fixing hole 713 is opened at the middle position of the first fixing plate 71 and penetrates through the first fixing plate 71. The positioning piece 711 is in a plate-like structure and is fixedly connected to the first fixing plate 71. The extending direction of the positioning piece 711 is the same as that of the second fixing plate 72, that is, the positioning piece 711 also extends towards the frame 51 to be connected with the second groove 5121. In this embodiment, the positioning piece 711 is disposed substantially perpendicular to the first fixing plate 71; of course, in other embodiments, the positioning piece 711 and the first fixing plate 71 may also be disposed at an acute angle or an obtuse angle. Preferably, two positioning pieces 711 are provided and are respectively located on both sides of the fixing hole 713, and the two positioning pieces 711 and the fixing hole 713 are on the same straight line.

[0096] A plurality of reinforcing ribs 712 are provided on the first fixing plate 71 and extend outward from the first fixing plate 71. In this embodiment, four reinforcing ribs 712 are provided and extend along the length direction and the width direction of the first fixing plate 71 respectively to increase the support strength of the fixing member 70 and ensure that the fixing member 70 is not easily deformed during use. Of course, in other embodiments, the number and position of the reinforcing ribs 712 can be set according to actual situations.

[0097] When the fixing member 70 is connected to the frame assembly 50, a part of the first fixing plate 71 abuts against the second side plate 512, and the other part abuts against the abutting surface 5221 to cover the joint edge seam formed by the two-by-two joint of the frame 51 and the corner frame 52 through the fixing member 70. The positioning piece 711 cooperates with the second groove 5121 to realize the connection and positioning between the fixing member 70 and the frame 51. The second groove 5121 in the present invention is a threaded groove, and the fixing hole 713 corresponds to the second groove 5121, so that the fixing member 70 and the frame 51 can be further fixedly connected by an external fastener (such as a screw) passing through the fixing hole 713 and being threadedly connected to the second groove 5121. Of course, the second groove 5121 may also be an ordinary groove as long as it can play a role in assisting in fixing the frame 51 and the fixing member 70.

[0098] The mask 60 is provided with a step portion 61 and a mating groove 62 located below the step portion 61. The second fixing plate 72 is inserted into the mating groove 62 to connect the mask 60 and the fixing member 70. When assembling the frame 51, the mask 60 and the fixing member 70, the mask 60 and the fixing member 70 can be first connected by inserting the second fixing plate 72 into the mating groove 62, then the frame 51, the mask 60 and the fixing member 70 can be connected to each other by inserting the positioning piece 711 into the second groove 5121, and finally the fixing member 70 and the frame 51 can be locked and fixed by a fastener passing through the fixing hole 713 and the second groove 5121 in sequence. At this time, the fixing connection of the frame 51, the mask 60 and the fixing member 70 is completed.

[0099] The installation process of the lighting fixture 100 of the present invention is as follows: First, fix the fixing base 10 to the ceiling; then, assemble the driving module 30 and the light source module 40 onto the connecting base 20, and at the same time fix and connect the frame assembly 50 and the mask 60 together through the fixing member 70 and assemble them onto the connecting base 20 to form the main body part of the lighting fixture; then, rotate the rotating member 21 on the connecting base 20, hang the main body part of the lighting fixture onto the fixing base 10 through the rotating member 21, and fix the rotating member 21 to the fixing base 10; finally, push the main body part of the lighting fixture as a whole towards the fixing base 10 until the sliding assembly 22 on the connecting base 20 is mechanically connected to the slot 121 on the fixing base 10, and at the same time the first connector 17 is electrically docked with the second connector 24, and at this time the installation of the lighting fixture 100 is completed.

[0100] The disassembly process of the lighting fixture 100 of the present invention is as follows: First, manually push the second connecting arm 2265 of the sliding member 226 so that the elastic member 227 is compressed until the slider 221 disengages from the slot 121 of the fixing base 10; then, pull the main body part of the lighting fixture away from the fixing base 10 so that the second connector 24 disengages from the slot 1710 of the first connector 17 and the rotating member 21 rotates; then, release the restriction of the positioning member 16 on the rotating member 21; finally, take out the rotating member 21 from the fixing member 15, and the disassembly of the main body part of the lighting fixture from the fixing base 10 can be completed.
