[0091] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0092] The technical solutions provided by each embodiment of the present application will be described in detail below with reference to the drawings.

[0093] As Figures 1-4 shown, and with reference to Figures 9 to 11 , an embodiment of the present application discloses a magnetic conductive track 1, which is in a long strip flat shape and includes a main body portion 10, a magnetic element 11, an insulating portion 12, a conductive portion 13, and end portions 14 provided at both ends of the main body portion 10.

[0094] The main body portion 10 extends along the length direction and is flat. It includes an adsorption wall 101, a mounting wall 102 arranged parallel and opposite to the adsorption wall 101, a pair of side walls 103 connecting the adsorption wall 101 and the mounting wall 102, and a pair of partition walls 104 arranged parallel to the side walls 103 and located between the side walls 103. The outer surface of the adsorption wall 101 is an adsorption surface 1010, and the outer surface of the mounting wall 102 is a mounting surface 1020. The above-mentioned side walls 103 and partition walls 104 respectively form a conductive groove 105 extending along the length direction and located on both sides and a receiving space 106 located between the conductive grooves 105 with the adsorption wall 101 and the mounting wall 102. Two long and narrow slots 107 are opened from the adsorption wall 101 towards the mounting wall 102. The slots 107 are located above the conductive groove 105 and communicate with the conductive groove 105. The adsorption wall 101 located between the slots 107 is also provided with at least two oval mounting holes 108 near both ends. The number of the mounting holes 108 is set according to the length of the magnetic conductive track 1. Corresponding to the mounting holes 108, the magnetic element 11 and the mounting wall 102 are respectively provided with mounting holes 110 and 109. The three are communicated along the height direction, and the size of the mounting hole 109 of the mounting wall 102 is smaller than the mounting holes 109 of the magnetic element 11 and the mounting holes 108 of the adsorption wall. The mounting holes 108, 109, and 110 are used for screws to pass through, and the screw heads finally press on both sides of the mounting hole 109 of the mounting wall 102 and are locked with the mounting base (ceiling or wall) so as to fix the magnetic conductive track 1 to the mounting base. After the installation is completed, the mounting holes 108 of the adsorption wall 101 are blocked and closed by a blocking piece (not shown). Specifically, the blocking piece can be arranged on the surface of the magnetic element 11 through glue.

[0095] The insulating portion 12 is received in the conductive groove 105. It includes a horizontal bottom wall 120, a first side wall 121 vertically extending from the bottom wall 120, a horizontal wall 123 horizontally extending from the first side wall 121 towards each other, and a second side wall 122 vertically extending from the horizontal wall 123. The distance between the second side walls 122 is smaller than the distance between the first side walls 121. Therefore, a first space 124 is formed by enclosing between the bottom wall 120 and the first side wall 121; a second space 125 communicating with the first space 124 is formed by enclosing between the horizontal wall 123 and the second side wall 122. The first space 124 and the second space 125 form a receiving portion 126 of the insulating portion 12. The first side wall 121 is located between the side walls of the conductive groove 105, that is, between the side walls 103 and the partition walls 104 and forms a surface-to-surface contact, preferably an interference fit; while the second side wall 122 is located between the side walls of the slot 107, so that the insulating portion 12 is laid on the inner walls of the conductive groove 105 and the slot 107 to provide reliable insulation. The free end of the second side wall 122 is configured to be slightly lower than or flush with the adsorption surface 1010.

[0096] The conductive parts 13 are two and are in flat strip shapes, being the positive electrode and the negative electrode respectively, and are respectively inserted into the first space 124 of the insulating part 12, so as to be located in the conductive groove 105, and both ends of them respectively extend beyond the two end faces 100 of the main body part 10. The conductive terminals of the lamp adsorbed and assembled on the magnetic conductive track 1 enter the first space 124 through the second space 125 so as to form an electrical connection with the conductive parts 13.

[0097] The magnetic element 11 is in a flat sheet shape, and is inserted into the receiving space 106 of the main body part 10, and at least adheres to the inner surface of the adsorption wall 101, so as to be adsorbed with the magnetic mounting part of the lamp. Both ends of the magnetic element 11 are located in the receiving space 106 and do not extend beyond the two end faces 100 of the main body part 10. The magnetic element 11 can be respectively attached to the inner surface of the adsorption wall 101 and the inner surface of the mounting wall 102. In a preferred embodiment of the present application, the magnetic element 11 is arranged to adhere to the inner surface of the adsorption wall 101, and two protrusions 1022 are arranged on the inner surface of the mounting wall 102 to abut against the surface of the magnetic element 11 to ensure the assembly reliability.

[0098] Please further refer to Figures 5-11 , the end parts 14 are arranged at both ends of the main body part 10 and form an electrical connection with the conductive parts 13. The end parts 14 include an insulating body 140 and conductive terminals 143 received in the insulating body 140.

[0099] The conductive terminals 143 are a pair, and each conductive terminal 143 includes a base part 1430 in a flat plate shape located in a vertical plane, a first docking part 1431 and a second docking part 1432 respectively extending from the base part 1430 in opposite directions. The first and second docking parts 1431, 1432 respectively include a pair of elastic components extending from the upper and lower edges of the base part 1430 and bent towards each other. Near the free ends, the elastic components are close to each other and the free ends form elastic piece guiding parts 1433 away from each other.

[0100] The insulating body 140 can be integrally formed with the conductive terminals 143, and includes a pair of conductive insertion parts 144 extending from its first end face 1403 and a positioning insertion part 145 located between the conductive insertion parts 144.

[0101] The end face of the conductive insertion part 144 is provided with an opening. The elastic piece guiding parts 1433 of the first docking parts 1431 of a pair of conductive terminals 143 are adjacent to the conductive insertion part 144. After the end part 14 is assembled to the main body part 10, the conductive part 13 passes through the opening of the conductive insertion part 144 and is assembled between the paired elastic components of the first docking part 1431, so as to form an electrical connection with the conductive terminal 143. A guiding and positioning part 1440 is protrudingly arranged on a surface of the conductive insertion part 144. The guiding and positioning part 1440 is a pair of protrusions, the width of which is equivalent to that of the slot 107. When the end part 14 is assembled with the main body part 10, the guiding and positioning part 1440 enters the slot 107. The positioning and insertion part 145 is inserted into the receiving space 106 and abuts against the end of the magnetic element 11 to provide positioning for the magnetic element 11 in the length direction.

[0102] The insulating body 140 has a pair of positioning holes 146 located on the outer side and recessed from its second end face 1404 towards the first end face 1403, and a pair of conductive insertion holes 147 located between the positioning holes 146 and adjacent to the positioning holes 146. The second docking part 1432 is configured such that its elastic piece guiding part 1433 is received in the conductive insertion hole 147 for forming an electrical connection with the adapter 2 and thus electrically connecting with other magnetic attraction conductive tracks.

[0103] The insulating body 140 further includes a first surface 1401 and a second surface 1402 opposite thereto, which are flush with the adsorption surface 1010 and the installation surface 1020 of the main body part 10 respectively, so as to form a flat structure for facilitating height reduction.

[0104] In a preferred embodiment of the present application, the insulating body 140 is formed by assembling a first housing 141 and a second housing 142 arranged in the up and down directions. The conductive terminal 143 is clamped and received between the first housing 141 and the second housing 142. The first surface 1401 is arranged on the first housing 141, and the second surface 1402 is arranged on the second housing 142. Therefore, the above structures are all formed by the combination of the first housing 141 and the second housing 142.

[0105] Specifically, two conductive terminal receiving grooves 1410 are formed by extending from the surface of the first housing 141 opposite to its first surface 1401. Each conductive terminal receiving groove 1410 is composed of two staggered cavities 1412 that are respectively communicated with the staggered conductive insertion parts 144 and conductive insertion holes 147, and respectively receive the first docking part 1431 and the second docking part 1432 of the conductive terminal 143. Between the two conductive terminal receiving grooves 1410 adjacent to the first end face 1403, a pair of positioning elements 1411 and a positioning insertion part 145 protruding from the first end face 1403 are provided. The positioning element 1411 can be a pair of positioning columns protruding in the height direction, or a positioning element formed with a positioning groove. A positioning hole 146 is formed between the two conductive terminal receiving grooves 1410 adjacent to the second end face 1404 and the side wall.

[0106] Correspondingly, the second housing 142 is provided with a partition wall 1422 for forming two cavities 1420 to cooperate with the conductive terminal receiving grooves 1410 to receive the conductive terminal 143. A positioning element 1421 is formed in the cavity 1420 and is matched with the positioning element 1411 of the first housing 141. The cavities 1420 are respectively communicated with the conductive insertion part 144, the conductive insertion hole 147, and the positioning hole 146.

[0107] In summary, for the magnetic conductive track 1 provided in the present application, through the direct surface contact between the adsorption surface 1010 and the installation surface 1020 and the adsorption surface and the installation base of the lamp respectively, the height of the magnetic conductive track 1 is effectively reduced. Moreover, through the conductive terminal 143 with a flat structure designed to extend in the reverse direction, the height of the end portion 14 is effectively reduced, and the first surface 1401 and the second surface 1402 of the end portion 14 can be flush with the adsorption surface 1010 and the installation surface 1020 respectively. The overall structure of the magnetic conductive track 1 is simple, realizing an ultra-thin structure design and effectively reducing costs.

[0108] In order to flexibly arrange the magnetic conductive track 1 provided in the present application, various arrangements can be realized to meet different requirements. The present application also provides an adapter 2, as Figures 12-26 shown. It has various forms and can realize cascade connection methods such as linear connection, planar L-shaped connection, vertical L-shaped connection, cross-shaped connection, T-shaped connection, etc. of the magnetic conductive track 1. The system composed of the adapter 2 and at least two magnetic conductive tracks 1 is a magnetic conductive track system 1000. The adapter 2 realizes mechanical connection and electrical connection with the magnetic conductive track 1, and after cascading the magnetic conductive tracks 1, it is flush with the installation surface 1020 of the magnetic conductive track 1 and the first surface 1401 of the end portion 14 and is respectively arranged in contact with the surface of the installation base. Therefore, the magnetic conductive track system 1000 has a very small thickness, realizing an ultra-thin structure design.

[0109] In other embodiments, the adapter 2 is not limited to cascading the magnetic attraction conductive tracks 1, and may also be other electrical devices.

[0110] Corresponding to the above cascading method, the adapter 2 has various structures, which will be described separately below.

[0111] Please refer to Figures 12-26 , the adapter 2 includes an insulating body 20 and conductive terminals 23 disposed within the insulating body 20 and partially protruding from the insulating body 20 to form an electrical connection with the end portion 14 of the magnetic attraction conductive track 1. The insulating body 20 may be integrally formed with the conductive terminals 23, or may include a first body 21 and a second body 22 assembled with the first body 21 in the height direction, and the conductive terminals 23 are clamped between the first body 21 and the second body 22. The insulating body 20 is square and has four sides, has a first surface 204 and an opposite second surface 206, and at least includes a main body portion 201 and a guiding portion 202 extending from the main body portion 201. The conductive terminals 23 at least include a base portion 231 and a docking portion 232 extending from the base portion 231 and exceeding the main body portion 201 of the insulating body 20. The guiding portion 202 of the insulating body 20 is disposed adjacent to the docking portion 232 and is parallel, so as to guide and protect the docking portion 232. When the adapter 2 is docked with the end portion 14 of different magnetic attraction conductive tracks 1, the guiding portion 232 is inserted into the positioning hole 146, and at the same time, the docking portion 232 enters the end portion 14 from the positioning insertion portion 145 and forms an electrical connection with the second docking portion 1432 of the conductive terminal 143. In order to accommodate the conductive terminals 23, the first body 21 and the second body 22 respectively form a receiving space 24 for receiving the base portion 231 of the conductive terminals 23 in the middle and several receiving channels 25 communicating with the receiving space 24, and the docking portion 232 is partially accommodated in the receiving channels 25 and extends beyond the insulating body 20. Therefore, the first surface 204 of the assembled adapter 2 is flush with the mounting surface 1020 of the magnetic attraction conductive track 1 and the first surface 1401 of the end portion 14, and is both disposed in contact with the surface of the mounting base. The second surface 206 of the adapter 2 is flush with the adsorption surface 1010 of the magnetic attraction conductive track 1 and the second surface 1402 of the end portion 14, so the overall structure is flat and simple, and the height is low.

[0112] Specifically, according to different cascading forms, the adapter 2 has different structures, such as Figures 12 to 14As shown, if the magnetic attraction conductive track 1 is connected in a cross shape, the adapter 2 includes a quadrilateral insulating body 20 and a pair of guiding portions 202 that extend from each side edge of the insulating body 20 and are close to both ends. The conductive terminal 23 includes a quadrilateral base portion 231 and four groups of docking portions 232 that extend parallel to each other from each side edge of the base portion 231. The docking portions 232 are adjacent to their respective guiding portions 202 and are located between a pair of guiding portions 202 on the same side. The docking portions 232 are arranged in pairs, being the positive electrode and the negative electrode respectively. Therefore, the adapter 2 can form mechanical and electrical connections with the ends 14 of the four magnetic attraction conductive tracks 1 respectively, and arrange the four magnetic attraction conductive tracks 1 in a cross shape to form a cross-shaped magnetic attraction conductive track system 1000.

[0113] If the magnetic attraction conductive track 1 is connected in a straight line, please refer to Figures 15 to 17 , then the adapter 2 includes a quadrilateral insulating body 20 and guiding portions 202 that extend from opposite side edges of the insulating body 20 and are parallel to each other. The conductive terminal 23 includes a quadrilateral base portion 231 and docking portions 232 that extend from opposite side edges of the base portion 231 and are parallel to each other. Therefore, the adapter 2 can form mechanical and electrical connections with the ends 14 of the two magnetic attraction conductive tracks 1 respectively, and arrange the two magnetic attraction conductive tracks 1 in a cross shape to form a cross-shaped magnetic attraction conductive track system 1000.

[0114] If the magnetic attraction conductive track 1 is connected in a planar L shape, please refer to Figures 18 to 20 , then the adapter 2 includes a quadrilateral insulating body 20 and guiding portions 202 that extend from adjacent side edges of the insulating body 20 and are parallel to each other. The conductive terminal 23 includes a quadrilateral base portion 231 and docking portions 232 that extend from adjacent side edges of the base portion 231 and are parallel to each other. Therefore, the adapter 2 can form mechanical and electrical connections with the ends 14 of the two magnetic attraction conductive tracks 1 respectively, and arrange the two magnetic attraction conductive tracks 1 in an L shape within the plane to form an L-shaped magnetic attraction conductive track system 1000.

[0115] If the magnetic attraction conductive track 1 is connected in an L shape located in mutually perpendicular planes, please refer to Figures 21 to 23, the adapter 2 includes an L-shaped insulating body 20, and the insulating body 20 includes a first body 21 in a flat plate shape located in the horizontal plane and an L-shaped second body 22 assembled with the first body 21.

The conductive terminals 23 include a first conductive terminal 233 located in the horizontal plane and a second conductive terminal 234 perpendicular to the first conductive terminal 233 and located in the vertical plane. The first conductive terminal 233 and the second conductive terminal 234 respectively form parallel docking portions 232 by extending from their horizontal and vertical side edges. Another horizontal side edge of the first conductive terminal 233 extends to form a protruding portion 2330, and the second conductive terminal 234 is correspondingly provided with an opening 2340 to receive the protruding portion 2330 to form an electrical connection therebetween. In other embodiments, the positions of the opening 2340 and the protruding portion 2330 can be interchanged. The first conductive terminal 233 is clamped and received between the horizontal portions of the first body 21 and the second body 22; the second conductive terminal 234 is received in the vertical portion of the second body 22. Therefore, the adapter 2 can respectively form mechanical and electrical connections with the ends 14 of two magnetic conductive tracks 1 located in the horizontal plane and the vertical plane respectively, and arrange the two magnetic conductive tracks 1 in an L shape located in different planes, thus forming a three-dimensional L-shaped magnetic conductive track system 1000. In this embodiment, the first surface 204 is the upper surface of the first body 21, and the second surface 206 is the rear surface of the second body 22. In the assembled L-shaped magnetic conductive track system 1000, the first surface 204 is flush with the mounting surface 1020 of the main body portion 10 of one of the magnetic conductive tracks 1 and the first surface 1401 of the end 14 and is flush and fitted with the horizontal surface of the mounting base, and the second surface 206 is flush with the mounting surface 1020 of the main body portion 10 of the other conductive track 1 and the first surface 1401 of the end 14 and is flush and fitted with the vertical surface of the mounting base.

The conductive terminals 23 include a quadrilateral base portion 231 and mutually parallel docking portions 232 formed by extending from three consecutive side edges of the base portion 231. Therefore, the adapter 2 can respectively form mechanical and electrical connections with the ends 14 of three magnetic conductive tracks 1, and arrange two magnetic conductive tracks 1 in a T shape to form a T-shaped magnetic conductive track system 1000.

[0117] The magnetic adsorption conductive track 1 cascaded through the adapter can be magnetically adsorbed to various electrical devices and achieve electrical connection, which is convenient and reliable. The following are several examples of electrical devices 3, 4, 5, and 6 that can be connected to the magnetic adsorption conductive track 1. The electrical devices 3, 4, 5, and 6 and the magnetic adsorption conductive track 1 form an electrical system 2000. The electrical devices 3, 4, 5, and 6 can be a driving power supply or a lighting fixture, an intelligent control device or a sensor module, etc. Among them, the driving power supply 3 can receive the power of the commercial power and convert it into the power required by electrical devices such as lighting fixtures 4, 5, and 6 or intelligent control devices or sensor modules; while electrical devices such as lighting fixtures 4, 5, and 6 or intelligent control devices or sensor modules can also be provided with a driving device by themselves to achieve power conversion. Moreover, in other embodiments, the electrical devices are not limited to the types described above, and can also be any electrical device configured to match the above-mentioned magnetic adsorption conductive track 1.

[0120] The driving module 34 includes various circuit modules (not labeled), as well as a control module, a Bluetooth module, or a wifi module 35 (the control module can be integrated with a Bluetooth module or a wifi module). The driving module 34 has a circuit board (not labeled) for setting the above modules. The circuit board is electrically connected to the wire 33 and the electrical connection module 32 respectively. The wire 33 is connected to the external commercial power to supply power to the driving power supply 3. The circuit board of the driving module 34 is electrically connected to the electrical connection module 32 through the wire, and the electrical connection module 32 is assembled on the driving module 34 and magnetically adsorbed on the magnetic adsorption conductive track 1 to form an electrical connection, so that the driving power supply 3 supplies power to the magnetic adsorption conductive track 1 and supplies power to other lamps.

[0121] The electrical connection module 32 is set on the main body 30 and includes a housing 320 formed by extending longitudinally, a magnet 323 received in the housing 320, and a conductive module 324. The housing 320 includes a first housing 321 and a second housing 322 assembled with the first housing 321 in the height direction. The above magnet 323 and conductive module 324 are received between the first housing 321 and the second housing 322. The longitudinal extension direction is the length extension direction of the magnetic adsorption conductive track 1.

[0122] The first housing 321 and the second housing 322 are hollow. After they are assembled, a receiving space for receiving the magnet 323 and the conductive module 324 is formed. Openings are provided at one end of the first housing 321 and the second housing 322 for the wire 33 to pass through. There are a plurality of magnets 323, which are arranged at intervals in the receiving space and are close to the second housing 322 so as to be adsorbed to the magnetic elements 11 of the magnetic conductive track 1. After assembly, the surface of the second housing 322 fits the adsorption surface 1010 of the magnetic conductive track 1. The second housing 322 is L-shaped, and a raised portion 3222 is formed at the part where the opening for the wire 33 to pass through is provided, and a height difference is formed with the base portion 3223. In a preferred embodiment of the present application, a strip-shaped mating portion 3220 extending along the longitudinal direction is protrudingly provided on the outer surface 32230 of the base portion 3223 facing the adsorption surface 1010 of the magnetic conductive track 1, and the outer surface 32230 serves as a mating surface. Corresponding to the position of the conductive module 324, a plurality of grooves 3221 are formed at intervals in the mating portion 3220 as conductive terminal receiving portions 3221, and the conductive terminals 3241 are partially received in the grooves 3221 and extend beyond the mating portion 3220.

[0123] The conductive module 324 is located between the magnets 323. The conductive module 324 includes a circuit board 3240 and conductive terminals 3241 provided on one surface of the circuit board 3240. The conductive terminals 3241 are electrically connected to the built-in circuit of the circuit board 3240, and are electrically connected to the circuit board of the driving module 34 through wires or conductive terminals (not shown) provided on the other surface of the circuit board 3240 to obtain the mains power transmitted by the wire 33 and the current transformed by the circuit board of the driving module 34. In other embodiments, the conductive module 324 can also be connected to the circuit board of the driving module 34 through another set of conductive terminals.

[0124] After the driving power supply 3 is adsorbed and assembled on the magnetic conductive track 1, the end 14 of the magnetic conductive track 1 abuts against one end of the convex portion 3222. The magnetic conductive track 1 is located above the base portion 3223 and is flush with the surface of the convex portion 3222, so as to form a flat, simple and ultra-thin configuration of the magnetic conductive track 1. Then, power is supplied to the magnetic conductive track 1 through the electrical connection between the first conductive terminal 3241 and the conductive portion 13 of the magnetic conductive track 1. The first conductive terminal 3241 is an elastic needle-shaped and retractable one. The mating portion 3220 and the first conductive terminal 3241 jointly extend into the second space 125 of the insulating portion 12. After the first conductive terminal 3241 enters the second space 125 from the first space 124 of the insulating portion 12 of the magnetic conductive track 1, it abuts against the surface of the conductive portion 13 and is compressed, so as to apply a reaction force to ensure the reliable electrical connection between the two. The mating surface 32230 of the base portion 3223 fits with the adsorption surface 1010 of the magnetic conductive track 1, and the magnet 323 adsorbs with the magnetic element 11 behind the adsorption surface 1010, so as to combine the driving power supply 3 with the magnetic conductive track 1. The mating portion 3220 which is jointly assembled with the conductive terminal 3241 into the magnetic conductive track 1 enhances the bonding force between the two. The mating surface 32230 that is in surface-to-surface fit with the adsorption surface 1010 ensures the lowest height of the electrical system 2000, and the effective adsorption and combination of the magnet 323 and the magnetic element 11. Therefore, the driving power supply 3 provided by the present application can realize mechanical connection and power supply by adsorbing on the magnetic conductive track 1 and being electrically connected with the conductive portion 13, which is convenient to use.

[0125] Please refer to Figures 32 to 42 , the electrical device conforming to the second embodiment of the present application is a lighting fixture 4, which can be adsorbed and assembled on the magnetic conductive track 1 and realize electrical connection with the magnetic conductive track 1 to supply power to the lighting fixture 4. In the preferred embodiment of the present application, the lighting fixture 4 is a linear fixture, generally referred to as a strip light. The lighting fixture 4 and the magnetic conductive track 1 form an electrical system 2000 conforming to the second embodiment of the present application.

[0126] The lighting fixture 4 includes a main body 40 extending along the longitudinal direction, a reflection layer 41, a light guide element 42, a mask 43 sequentially arranged along the height direction on the main body 40, and end caps 44 arranged at both ends of the main body 40. In the preferred embodiment of the present application, the mask 43 is a diffusion plate for uniform light. The end caps 44 are locked to both ends of the main body 40 by screws, but are not limited thereto. It further includes a magnet module 45, an electrical connection module 46 and a lighting module 47, which are housed in the main body 40.

[0127] To house the magnet module 45, the electrical connection module 46, and the lighting module 47, the main body 40 includes a bottom wall 401, a pair of side walls 402 extending from the bottom wall 401, and a top wall 403 extending towards each other from the other ends of the side walls 402. Two partition portions 404 are formed along the length direction in the region of the bottom wall 401 adjacent to the side walls 402. The partition portions 404 are parallel to the side walls 402 and divide the main body 40 into three regions. Two lighting module housing portions 405 formed between the partition portions 404 and the side walls 402 and a magnet module housing portion 406 located between the partition portions 404 are respectively used to house the lighting module 47 and the magnet module 45. To house the electrical connection module 46, an opening 4010 is formed in the middle of the bottom wall 401 for snap-fitting with the electrical connection module 46. Due to the existence of the opening 4010, the partition portions 404 are divided into two parts along the length direction. Correspondingly, the magnet module 45 has two parts, which are respectively housed in the magnet module housing portion 406 and are separated by the opening 4010 and the electrical connection module 46 housed in the opening 4010.

[0128] The magnet module 45 includes two strip-shaped fixing portions 450, on the surface of which a number of pairs of positioning elements 4501 are provided. Groups of magnets 451 are stacked side by side between the positioning elements 4501 and are housed together in the magnet module housing portion 406.

[0129] The lighting module 47 includes a long strip-shaped light source substrate 470, a number of light sources 471 provided on the light source substrate 470, and at least two electrodes 472. The light sources 471 and the electrodes 472 are arranged along the height direction respectively. In the preferred embodiment of the present application, the electrodes 472 are arranged in the middle of the lower row of the light source substrate 470 and are respectively a positive electrode and a negative electrode. In other preferred embodiments, it may also include electrodes for transmitting various control signals, dimming, color mixing, etc. The lighting module 47 is housed in at least one of the lighting module housing portions 405. In other embodiments, the lighting module 47 may have two groups and be respectively housed in a group of lighting module housing portions 405 adjacent to the side walls 402.

[0130] There is a height difference between the top wall 403 and the surface of the partition portion 404 facing the top wall 403, forming an optical element housing space 407. The above-mentioned reflective layer 41, light guide element 42, and mask 43 are respectively housed in the optical element housing space 407 and are sandwiched between the top wall 403 and the partition portion 404. After assembly, the light source 471 of the lighting module 47 faces the side wall of the light guide element 42. Therefore, the emitted light of the light source 471 enters the interior of the light guide element 42 from the side wall of the light guide element 42 and is reflected multiple times by the upper and lower surfaces and then exits from at least one surface. In the embodiment of the present application, it exits from the surface facing the mask 43. The reflective layer 41 is located on the other surface of the light guide element 42 and reflects the light incident on this surface back into the light guide element 42 to increase the light efficiency.

[0131] The 46 groups of the electrical connection modules are arranged in the opening 4010, and include a housing 460 formed by extending longitudinally and an electrical connector 463. The housing 460 includes a first housing 461, a second housing 462 and the electrical connector 463 disposed between the first housing 461 and the second housing 462.

[0132] The electrical connector 463 includes a base body 4630 with circuits built therein, two pairs of first conductive terminals 4631 disposed on the base body 4630 and a pair of second conductive terminals 4632 disposed on the base body 4630. In the embodiment of the present application, both the first conductive terminals 4631 and the second conductive terminals 4632 are pin-shaped conductive terminals with springs inside. When stressed, the springs contract and apply a restoring force to increase the reliability of the electrical connection. The first conductive terminals 4631 can be at least one pair and are used for electrically connecting the lighting fixture 4 to the conductive part 13 after the lighting fixture 4 is assembled on the magnetic conductive track 1. The two groups of first conductive terminals 4631 are respectively perpendicular to the base body 463 and disposed at the four corners of the base body 463, and are welded by perforation. Of course, other connection methods such as surface welding can also be used, and are electrically connected to the circuits inside the base body 463. The second conductive terminals 4632 are surface-welded to the surface of the base body 463 and parallel to one surface of the base body 463. Of course, other connection methods can also be used, and are electrically connected to the circuits inside the base body 463, so as to be electrically connected to the first conductive terminals 4631. The second conductive terminals 4632 are elastically abutted against the electrodes 472 of the lighting module 47 to form an electrical connection. Therefore, after the first conductive terminals 4631 draw power from the magnetic conductive track 1, the power is transmitted to the second conductive terminals 4632 through the circuits of the base body 463 to supply power to the lighting module 47. At the same time, the magnet 451 of the magnet module 45 is adsorbed on the adsorption wall 101 of the magnetic conductive track 1.

[0133] The first housing 461 and the second housing 462 are snap-fitted together and are snap-fitted to the opening 4010 of the lighting fixture 4. The second housing 462 includes a bottom wall 4620 and a pair of side walls 4621 extending from both sides of the bottom wall 4620 toward the first housing 461. The middle of the side wall 4621 is torn and folded outward to form a latching portion 4622, which is latched to the peripheral wall of the opening 4010. Four round holes are provided at the four corners of the bottom wall 4620 for the first conductive terminals 4631 to pass through, and a plurality of mating portions 4623 protrude from the surface 46200 (serving as a mating surface) of the bottom wall 4620 facing the magnetic attraction conductive track 1. The first conductive terminals 4631 are located between the mating portions 4623 and extend beyond the mating portions 4623. The mating portions 4623 can protect the first conductive terminals 4631 and extend into the second space 125 of the magnetic attraction conductive track 1 together with the first conductive terminals 4631. The first conductive terminals 4631 further enter the first space 124 and elastically abut against the conductive portion 13 to form an electrical connection. And the bottom wall 4620 is attached to the adsorption surface 1010 of the magnetic attraction conductive track 1, that is, the mating surface 46200 is attached to the adsorption surface 1010, and the magnet 451 is adsorbed to the magnetic element 11 behind the adsorption surface 1010. The second conductive terminals 4632 partially extend beyond the side walls of the first housing 461 and the second housing 462 that are perpendicular to the side walls 4621, and are used to elastically abut against the electrodes 472 of the lighting module 47. The mating portions 4623 assembled into the magnetic attraction conductive track 1 together with the first conductive terminals 4631 enhance the binding force between the magnetic attraction conductive track 1 and the lighting fixture 4, and ensure that the height of the electrical system 2000 is low enough and the thickness is thin enough, realizing a simple structure.

The main body portion 530 extends beyond the gratings 531, and a plurality of fastening portions 532 are formed at intervals on the outer periphery of the side wall. After the mask 53 is assembled to the main body 50, it is snap-fitted with the fastening portion 501 on the inner wall of the main body 50. In the embodiment of the present application, the fastening portion 532 of the mask 53 is a hook, and the fastening portion 501 of the main body 50 is a recess formed inside it. The hook and the recess can be interchanged. The secondary optical element 573 is sandwiched between the primary optical element 572 and the gratings 531. One end of the gratings 531 is provided with an opening as a light inlet to correspondingly receive the incident light from the lens module, and the other end is also provided with an opening as a light outlet, and the side wall extends into a horn shape.

Correspondingly, the main body 50 also protrudes with a semi-circular pivoting portion 502 and is provided with a rotating shaft hole (not labeled). Therefore, both ends of the rotating shaft 52 are respectively received in the rotating shaft hole 5410 and the rotating shaft hole of the pivoting portion 502 of the main body 50 of the lamp body, and the electrical connection module 51 and the main body 50 can rotate relative to each other, realizing the adjustable range of the emitted light of the lighting module 57 of the main body 50.

The conductive terminals 561 are internally provided with springs and can be compressed to increase the reliability of electrical connection after being electrically connected to the magnetic adsorption conductive track 1, and they are also electrically connected to the internal circuitry of the substrate 560. In order to supply the power taken from the magnetic adsorption conductive track 1 to the lighting module 57, the conductive module 56 needs to be electrically connected to the driving part 58. In the embodiment of the present application, the substrate 560 of the conductive module 56 and the driving part 58 are electrically connected through a wire (not shown). However, in other embodiments, the substrate 560 may also be provided with spring-pin-shaped conductive terminals 561 on the other surface opposite to the surface where the conductive terminals 561 are provided, and the driving part 58 is provided with a conductive sheet on its circuit board for abutting against the spring-pin-shaped conductive terminals to form an electrical connection. The driving part 58 is electrically connected to the lighting module 57 through a wire, and converts the mains power into the power required by the lighting module 57 and supplies it to the lighting module 57. Since the driving power supply 3 converts the mains power into a 58V power supply, the lighting fixture 5 needs to be provided with a driving part 58 to further convert the 58V power supply into the voltage required by the lighting fixture 5.

[0141] There are two groups of magnet modules 55, and each group includes at least two magnets. The rectangular frame 540 of the main body part 54 is provided with a receiving space for receiving the magnet module 55, the conductive module 56 and the driving part 58.

[0142] The cover body 59 is locked to the main body part 54 by screws. The cover body 59 is generally flat, and has openings 591 at both ends. The magnet module 55 is received in the receiving space of the main body part 54 and protrudes from the cover body 59 through the openings 591. In a preferred embodiment of the present application, an outer surface 593 (as a mating surface) of the cover body 59 facing the adsorption surface 1010 of the magnetic adsorption conductive track 1 is provided with a strip-shaped mating part 590 and is located outside the openings 591. Corresponding to the positions of the conductive terminals 561 of the conductive module 56, a plurality of grooves 592 are formed in the mating part 590 as conductive terminal receiving parts 592. The conductive terminals 561 of the conductive module 56 protrude beyond the surface of the mating part 590 of the cover body 59 for electrical connection to the magnetic adsorption conductive track 1.

[0143] After the lighting fixture 5 is assembled on the magnetic conductive track 1 to form the electrical system 2000, the mating portion 590 and the conductive terminal 561 extend into the second space 125 of the magnetic conductive track 1 together, and the conductive terminal 561 further enters the first space 124 and elastically abuts against the conductive portion 13 to form an electrical connection. And the mating surface 593 of the cover body 59 fits against the adsorption surface 1010 of the magnetic conductive track 1, and the magnet module 55 adsorbs to the magnetic element 11 behind the adsorption surface 1010. The mating portion 590 assembled into the magnetic conductive track 1 together with the conductive terminal 561 enhances the bonding force between the magnetic conductive track 1 and the lighting fixture 5, and ensures that the electrical system 2000 is low enough in height and thin enough in thickness, realizing a simple structure.

[0144] Therefore, after the grille lamp 5 is adsorbed and assembled on the magnetic conductive track 1 through the conductive terminal 561 and the magnet module 55, the lighting module 57 can emit light as needed, be controlled, dimmable and color-tunable, etc., and can be adjusted in angle relative to the electrical connection module 51.
