[0024] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of the light bar and connector provided in this application.

[0026] like Figure 1 As shown, in the prior art, a contact is set at one end of the glass-based light bar, and the connector is connected through a slot. This solution is prone to damage due to repeated disassembly and assembly, and the connector can only be set at the end of the light bar, which is fixed in position and is not conducive to narrow frame design.

[0027] See also Figures 2 to 4 , Figure 2 is a structural diagram of the first embodiment of the light-emitting device provided by this application, Figure 3 is a structural diagram of the second embodiment of the light-emitting device provided by this application, Figure 4 It is a structural schematic diagram of the third embodiment of the light-emitting device provided in this application.

[0028] The present application provides a light emitting device 1 (see Figure 16 ), the lighting device 1 includes a connector 10, a carrier board 20 and a light bar 30. The connector 10 includes a main body 12 (see Figure 5 ) and connecting contacts 11; the light bar 30 has electrode contacts 31; the light bar 30 is partially clamped between the main body 12 and the carrier 20, and the electrode contacts 31 are arranged opposite to the connecting contacts 11; wherein, the light-emitting device 1 also includes a driving member 40; the driving member 40 controls the relative displacement between the carrier 20 and the connector 10 to clamp or release the light bar 30, thereby realizing the connection and disconnection of the electrode contacts 31 and the connecting contacts 11.

[0029] The relative displacement between the carrier board 20 and the connector 10 is controlled by the driving member 40 to clamp and release the light bar 30 clamped between the carrier board 20 and the connector 10, thereby achieving an electrical connection between the light bar 30 and the connector 10; in addition, a detachable connection between the light bar 30 and the connector 10 can also be achieved, making it easy to replace the connector 10.

[0030] Connector 10 is used to connect and secure light strip 30 and is shaped like a plate or ring. Driven by a driver 40, connector 10 and carrier board 20 can achieve relative displacement, bringing them closer together, thereby reducing the space between the light strip 30 and limiting its movement and securing it. Alternatively, connector 10 and carrier board 20 can be moved further apart, increasing the space between the light strip 30 and releasing it.

[0031] The carrier board 20 is in a plate shape. The carrier board 20 carries the light bar 30 and drives the light bar 30 to move together, thereby connecting the connection contacts 11 with the electrode contacts 31 located on the light bar 30 .

[0032] The light bar 30 is inserted along its length into the space between the connector 10 and the carrier 20. Electrode contacts 31 are provided on the light bar 30 and are positioned correspondingly to the connection contacts 11. When the carrier 20 and the connector 10 clamp the light bar 30, the electrode contacts 31 abut against the connection contacts 11 to achieve an electrical connection.

[0033] In some embodiments, the light bar 30 further includes a circuit board 32 and a light emitting element 33 (see FIG. Figure 5 ); the light-emitting element 33 is arranged on one side of the circuit board 32; the electrode contact 31 is located on the side of the circuit board 32 facing the light-emitting element 33 and is arranged towards the first side wall 122.

[0034] Circuit board 32 is electrically connected to light emitting element 33 and drives light emitting element 33 to emit light. Electrode contact 31 is a contact point of circuit board 32, and circuit board 32 is connected to the power supply through electrode contact 31. Specifically, circuit board 32 is electrically connected to connector 10 through electrode contact 31 and connection contact 11.

[0035] Exemplarily, the light emitting element 33 is a light emitting diode (LED).

[0036] Exemplarily, each light bar 30 includes a row of light emitting elements 33 arranged along the length direction of the light bar 30 .

[0037] The size and arrangement of the light emitting elements 33 are not limited here and can be selected according to actual needs. In other embodiments, the light bar 30 can include at least two rows of light emitting elements 33.

[0038] Exemplarily, the circuit board 32 is obtained by printing circuits on a glass substrate.

[0039] Exemplarily, the circuit board 32 is obtained by printing circuits on scrap glass.

[0040] Exemplarily, the electrode contact 31 is disposed protruding from a surface of the circuit board 32 close to the first side wall 122 , and the connection contact 11 is disposed protruding from a surface of the first side wall 122 toward the second side wall 123 .

[0041] In other embodiments, the electrode contacts 31 are embedded in the circuit board 32 , or the connecting contacts 11 are embedded in the first side wall 122 .

[0042] The driving member 40 is used to drive the carrier board 20 and / or the connector 10 to move.

[0043] There is at least one driving member 40, which is not limited here and can be selected according to actual needs.

[0044] In some embodiments, the driving member 40 is a stud 41. In other embodiments, the driving member 40 is a combination of a nut 42 and a stud 41.

[0045] In some embodiments, the connector 10 is a plate-shaped structure and is disposed opposite to the carrier 20 . That is, the main body 12 is a plate-shaped structure and is disposed opposite to the carrier 20 .

[0046] In one embodiment, the driving member 40 is a combination of a nut 42 and a stud 41. The stud 41 is fixed to the side of the connector 10 facing the carrier 20 and penetrates the carrier 20. A nut 42 is provided on the side of the carrier 20 away from the connector 10. The nut 42 is threadedly connected to the portion of the stud 41 extending from the carrier 20. Rotating the nut 42 moves the nut 42 toward the connector 10, thereby displacing the carrier 20 toward the connector 10 until the light bar 30 is clamped and the electrode contacts 31 and the connection contacts 11 abut against each other, thereby achieving an electrical connection between the light bar 30 and the connector 10. Rotating the nut 42 moves the nut 42 away from the connector 10, thereby displacing the carrier 20 away from the connector 10, thereby disconnecting the electrode contacts 31 from the connection contacts 11 and releasing the light bar 30.

[0047] In another specific embodiment, a stud 41 is fixed to the side of the carrier 20 facing the connector 10 and passes through the connector 10. A nut 42 is provided on the side of the connector 10 away from the carrier 20. The nut 42 is threadedly connected to the portion of the stud 41 extending from the connector 10. Rotating the nut 42 moves the nut 42 toward the carrier 20, thereby displacing the connector 10 toward the carrier 20 until the light bar 30 is clamped and the electrode contacts 31 abut against the connection contacts 11, thereby establishing an electrical connection between the light bar 30 and the connector 10. Rotating the nut 42 moves the nut 42 away from the carrier 20, thereby displacing the connector 10 away from the carrier 20, thereby disconnecting the electrode contacts 31 from the connection contacts 11 and releasing the light bar 30.

[0048] In another embodiment, a stud 41 is provided through both the connector 10 and the carrier 20. A nut 42 is provided on the side of the carrier 20 away from the connector 10, and a nut 42 is also provided on the side of the connector 10 away from the carrier 20. The nuts 42 are threadedly connected to the portions of the stud 41 extending from the connector 10 and the carrier 20, respectively. By rotating the nuts 42, the connector 10 and / or the carrier 20 are relatively displaced, thereby tightening or loosening the light bar 30 and disconnecting the electrode contacts 31 and the connection contacts 11.

[0049] By configuring the plate-like connector 10 and the carrier board 20 as well as various corresponding driving components 40, the light bar 30 is fixed with a simpler connector 10 structure. At the same time, the position and structure of the driving component 40 are flexibly set to adapt to more usage scenarios and save costs.

[0050] See also Figures 5 to 8 , Figure 5 is a structural diagram of the fourth embodiment of the light-emitting device provided by this application, Figure 6 is a structural diagram of the fifth embodiment of the light-emitting device provided by this application, Figure 7 is a structural diagram of the sixth embodiment of the light emitting device provided by this application, Figure 8 It is a structural schematic diagram of the seventh embodiment of the light-emitting device provided in this application.

[0051] In some embodiments, the main body 12 has a groove 121, and the groove 121 is in the first direction x1 (see Figure 16 ) through the main body 12; the two side walls of the groove 121 respectively constitute the main body 12 along the second direction y1 (see Figure 16 ) The first side wall 122 and the second side wall 123 are opposite to each other; the first direction x1 and the second direction y1 are arranged to intersect; the light bar 30 is placed in the groove body 121 along the first direction x1; the carrier 20 is located in the groove body 121; the light bar 30 is located on the side of the carrier 20 facing the first side wall 122; the driving member 40 is located on the side of the carrier 20 close to the second side wall 123; the driving member 40 is threadedly connected to the second side wall 123, and the displacement of the carrier 20 in the second direction y1 is controlled by rotating the driving member 40 to realize the connection and disconnection of the electrode contact 31 and the connection contact 11.

[0052] The main body 12 is annular and has a groove 121 extending along the first direction x1. The first side wall 122 and the second side wall 123 of the main body 12 are opposite to each other in the second direction y1 and serve as two opposite side walls of the groove 121 in the second direction y1.

[0053] Exemplarily, the first direction x1 is perpendicular to the second direction y1, and the main body 12 is a rectangular ring structure.

[0054] Exemplarily, the driver 40 is a screw including a stud 41. One end of the driver 40 is located outside the connector 10 (i.e., the screw head is located outside the connector 10 to facilitate screw rotation). The driver 40 penetrates the second side wall 123 of the connector 10 through a threaded hole 124 and abuts against the carrier 20. Rotating the driver 40 drives the carrier 20, thereby adjusting the distance between the carrier 20 and the first side wall 122 and causing the light bar 30 to follow the movement of the carrier 20, thereby clamping or releasing the light bar 30 and achieving connection and disconnection between the electrode contact 31 and the connection contact 11.

[0055] Specifically, in the initial state, the carrier 20 is located within the slot 121 and adjacent to the second sidewall 123. The light bar 30 is inserted into the slot 121 along the first direction x1 and is located on the side of the carrier 20 facing the first sidewall 122. At this point, the electrode contacts 31 of the light bar 30 are not in contact with the connection contacts 11. The light bar 30 is located between the carrier 20 and the first sidewall 122 and is in a released state.

[0056] When the carrier plate 20 is moved along the second direction y1 toward the first side wall 122, and the light bar 30 is inserted into the predetermined position of the slot 121, the driver 40 is screwed in. The driver 40, through threaded transmission, propels the carrier plate 20 along the second direction y1 toward the first side wall 122. The carrier plate 20 drives the light bar 30 to move synchronously, causing the electrode contacts 31 on the light bar 30 to gradually approach and eventually abut against the connection contacts 11, thereby clamping the light bar 30, achieving electrical connection and a fixed connection between the light bar 30 and the connector 10.

[0057] Compared with the design of the connector 10 as a plate structure, the connector 10 is set to a ring structure, which can limit the light bar 30 and the carrier board 20 along the width direction of the light bar 30, making it easier to clamp or release the light bar 30.

[0058] In other embodiments, the driver 40 includes a stud 41 and a nut 42. The stud 41 can be disposed on a surface of the carrier 20 facing the first sidewall 122 and located on opposite sides of the carrier 20 along the second direction y1. The nut 42 is located outside the connector 10. The stud 41 passes through the first sidewall 122 of the main body 12, and the portion extending outside the connector 10 is threadedly engaged with the nut 42.

[0059] In some embodiments, the light emitting device 1 further includes a plurality of limiting posts 51 extending along the second direction y1, and the limiting posts 51 extend along the third direction z1 (see FIG. Figure 15 ) are located on opposite sides of the light bar 30; the third direction z1 is perpendicular to the first direction x1 and is perpendicular to the second direction y1; the limiting column 51 is located between the first side wall 122 and the carrier 20 and is fixed to the first side wall 122 or the carrier 20.

[0060] The limiting posts 51 extend along the second direction y1. There are at least two limiting posts 51, which further limit the light bar 30 in the third direction z1 to prevent misalignment between the electrode contacts 31 and the connection contacts 11, leading to poor electrical connection. In some embodiments, the limiting posts 51 are located on the first sidewall 122 or the carrier 20; in other embodiments, some limiting posts 51 are located on the first sidewall 122, while others are located on the carrier 20.

[0061] Exemplarily, the limiting column 51 may be cylindrical or have other columnar structures.

[0062] The following description mainly takes an example in which the driving member 40 is located on a side of the carrier plate 20 away from the first side wall 122 and passes through the second side wall 123 .

[0063] In one embodiment, the limiting post 51 is located on a side of the carrier plate 20 close to the first side wall 122. When clamping the light bar 30, the limiting post 51 is spaced apart from the first side wall 122 to prevent the limiting post 51 from being too long and prematurely contacting the first side wall 122 before the light bar 30 is clamped, thereby preventing the light bar 30 from being clamped.

[0064] In another embodiment, the limiting post 51 is located on a side of the first side wall 122 close to the second side wall 123. When clamping the light bar 30, the limiting post 51 is spaced apart from the carrier plate 20 to prevent the limiting post 51 from being too long and prematurely contacting the carrier plate 20 before the light bar 30 is clamped, thereby preventing the light bar 30 from being clamped.

[0066] In other embodiments, the lighting device 1 further includes an elastic member 52. By providing the elastic member 52, during the process of releasing the light bar 30, elastic potential energy can be used to assist in the release of the light bar 30.

[0067] Exemplarily, the elastic member 52 is a spring 521, which is sleeved around the outer periphery of the retaining post 51 and partially extends beyond the retaining post 51. When the electrode contact 31 abuts the connection contact 11, the elastic member 52 is compressed. When the electrode contact 31 separates from the connection contact 11, the elastic potential energy of the elastic member 52 applies an elastic force to the retaining post 51 toward the carrier 20, assisting in displacing the carrier 20 away from the first sidewall 122, thereby releasing the light bar 30.

[0068] Exemplarily, the elastic member 52 is a spring 521 or a spring. The elastic member 52 is fixed to the end of the retaining post 51. Similarly, the provision of the elastic member 52 facilitates the release of the light bar 30. In one embodiment, the retaining post 51 is located on a side of the carrier 20 near the first side wall 122, and the elastic member 52 is fixed to the end of the retaining post 51 facing the first side wall 122.

[0069] In other embodiments, the limiting post 51 is located on a side of the first sidewall 122 close to the carrier 20 , and the elastic member 52 is fixed to the end of the limiting post 51 facing the carrier 20 .

[0071] In some embodiments, the light-emitting device 1 further includes a limiting groove 53, which is provided on the surface of the first side wall 122 facing the second side wall 123, or the limiting groove 53 is provided on the surface of the carrier 20 facing the first side wall 122; the limiting groove 53 and the limiting column 51 are provided in a one-to-one correspondence; wherein, when the connecting contact 11 and the electrode contact 31 are in abutting state, the limiting column 51 is inserted into the corresponding limiting groove 53 and is spaced apart from the bottom wall of the limiting groove 53; or, the light-emitting device 1 further includes an elastic member 52, and the elastic member 52 and the limiting column 51 are spaced apart. The positioning column 51 is connected to the end portion close to the limiting groove 53, and / or the elastic member 52 is connected to the bottom wall of the limiting groove 53; when the connecting contact 11 and the electrode contact 31 are in abutment, the elastic member 52 is in a compressed state, and the elastic member 52 is at least partially located in the limiting groove 53; or, the light-emitting device 1 also includes a spring 521, which is sleeved on the outer periphery of the limiting column 51, and the spring 521 is at least partially located outside the limiting groove 53; when the connecting contact 11 and the electrode contact 31 are in abutment, the elastic member 52 is in a compressed state.

[0072] When the connection contacts 11 and the electrode contacts 31 are in contact with each other, the limiting grooves 53 cooperate with the limiting posts 51 to limit the displacement of the carrier board 20 in the third direction z1 , thereby limiting the displacement of the light bar 30 .

[0073] The limiting groove 53 is provided on the surface of the first side wall 122 facing the second side wall 123, or the limiting groove 53 is provided on the surface of the carrier 20 facing the first side wall 122. The following mainly takes the limiting groove 53 provided on the surface of the first side wall 122 facing the second side wall 123 as an example.

[0074] In the first specific embodiment, as Figure 11 As shown, when the connection contact 11 and the electrode contact 31 are in contact, the limiting post 51 is inserted into the corresponding limiting groove 53 and is spaced apart from the bottom wall of the limiting groove 53. That is, this embodiment does not include the elastic member 52. Specifically, the limiting post 51 is disposed on the side of the carrier 20 near the first side wall 122. The provision of the limiting groove 53 not only limits the limiting post 51 but also prevents the limiting post 51 from interfering with the contact between the connection contact 11 and the electrode contact 31.

[0075] In the second specific embodiment, Figure 12 As shown, the light-emitting device 1 further includes an elastic member 52, which is connected to the end of the limiting column 51 near the limiting groove 53, and / or the elastic member 52 is connected to the bottom wall of the limiting groove 53. When the connection contact 11 and the electrode contact 31 are in abutment, the elastic member 52 is in a compressed state, and the elastic member 52 is at least partially located in the limiting groove 53. The setting of the limiting groove 53 can also limit the elastic member 52 to prevent the elastic member 52 from lateral displacement. The length of the elastic member 52 in the natural state can be greater than, less than or equal to the depth of the limiting groove 53, and there is no specific limitation. It can be selected according to actual needs.

[0076] In the third specific embodiment, the light-emitting device 1 further includes a spring 521, which is sleeved on the outer periphery of the limiting column 51, and the spring 521 is at least partially located outside the limiting groove 53; when the connecting contact 11 and the electrode contact 31 are in abutment state, the elastic member 52 is in a compressed state.

[0077] For example, in some embodiments, Figure 13 As shown, the spring 521 is sleeved on the outer circumference of the limiting column 51, and the spring 521 is located outside the limiting groove 53. The spring 521 can be fixedly connected to the limiting column 51 or non-fixedly connected. There are no excessive restrictions here and the choice is made according to actual needs. It should be noted that when the spring 521 is not fixedly connected to the limiting column 51, the spring 521 is in contact with the first side wall 122 and the carrier plate 20 respectively in a natural state to ensure that the spring 521 will not fall off during the process of releasing or clamping the light bar 30. When the spring 521 is not fixedly connected to the limiting column 51, the spring 521 can also be fixed in the limiting groove 53 or on the first side wall 122.

[0078] In other embodiments, Figure 14 and Figure 15As shown, the spring 521 is sleeved on the outer periphery of the limiting column 51, and the spring 521 is partially located outside the limiting groove 53. The portion of the spring 521 extending from the limiting column 51 is at least partially located in the limiting groove 53.

[0079] The functions of the elastic member 52 and the spring 521 are described above and will not be repeated here.

[0080] See also Figures 16 to 19 , Figure 16 is a schematic diagram of the three-dimensional structure of the fourteenth embodiment of the light-emitting device provided by this application, Figure 17 is a structural diagram of the fourteenth embodiment of the light-emitting device provided by the present application from another perspective, Figure 18 is a structural diagram of the fifteenth embodiment of the light-emitting device provided in this application, Figure 19 It is a structural schematic diagram of the sixteenth embodiment of the light-emitting device provided in this application.

[0081] In some embodiments, the electrode contact 31 is located in the middle area 300 of the circuit board 32 along the first direction x1; and the light bar 30 passes through the slot 121 along the first direction x1.

[0082] The connector 10 is arranged to clamp a light bar 30. It can be understood that the connector 10 is clamped in the middle area 300 of the light bar 30 along the first direction x1.

[0083] Each light strip 30 has two end regions 200 and a middle region 300 , and the middle region 300 is located between the two end regions 200 .

[0084] In some specific embodiments, Figure 16 and Figure 17 As shown, the electrode contacts 31 are located on the surface of the circuit board 32 facing the light emitting element 33 and are arranged on two opposite edges of the circuit board 32 along the third direction z1. That is, the electrode contacts 31 are located on the side of the light emitting element 33 along the third direction z1 to facilitate electrical connection with the connection contacts 11 of the connector 10. In other specific embodiments, such as Figure 18 As shown, the electrode contacts 31 are located on the surface of the circuit board 32 facing the light emitting elements 33 and are located between the light emitting elements 33 .

[0085] Compared with the prior art, the connector 10 is clamped in the middle area 300 of the light bar 30 along the first direction x1, which can avoid occupying the end space of the light bar 30, is conducive to achieving a narrow frame design, and facilitates the disassembly and replacement of the connector 10 without damaging the light bar 30.

[0086] In other embodiments, Figure 19As shown, the electrode contact 31 is located in the end area 200 of the circuit board 32 along the first direction x1; in the first direction x1, the end areas 200 of two adjacent light strips 30 close to each other are respectively inserted into the slot body 121 of the same connector 10 to realize the parallel setting of the two adjacent light strips 30 through the connector 10.

[0087] It can be understood that one connector 10 simultaneously clamps two light strips 30 to achieve splicing of the light strips 30 in the first direction x1, thereby solving the problem that the size of a single residual light strip 30 is insufficient to meet the requirements of a large-size display device 2.

[0088] See also Figures 20 to 21 , Figure 20 is a structural diagram of the seventeenth embodiment of the light-emitting device provided in this application, Figure 21 It is a structural schematic diagram of the eighteenth embodiment of the light-emitting device provided in this application.

[0089] In some embodiments, the connector 10 further includes a compensation light source 125 . The compensation light source 125 is disposed on a surface of the first side wall 122 away from the second side wall 123 .

[0090] The compensation light source 125 is used to provide supplementary light to the light bar 30 .

[0091] In some specific embodiments, in the first direction x1, the connector 10 is clamped between two adjacent light emitting elements 33, that is, the first side wall 122 is located between the two adjacent light emitting elements 33 (see FIG. Figure 18 Specifically, the first sidewall 122 of the connector 10 can be located between two adjacent light-emitting elements 33 of the same light bar 30, or at the junction of two light bars 30. Because the connector 10 is sandwiched between the light-emitting elements 33, the distance between the two adjacent light-emitting elements 33 increases, which reduces the light intensity at that location and affects light uniformity. Therefore, a compensating light source 125 is provided on the connector 10 to compensate for the light intensity at the location of the connector 10, thereby improving display uniformity.

[0092] In some other specific embodiments, in the second direction y1, the first sidewall 122 of the connector 10 blocks at least one light emitting element 33. That is, at least one light emitting element 33 enters the slot 121. Each light emitting element 33 is at least partially located in the slot 121.

[0093] Exemplarily, one light emitting element 33 is entirely located in the slot 121 .

[0094] Because the first sidewall 122 blocks the light emitted by the light emitting element 33, the light bar 30 emits abnormal light. By providing a compensation light source 125 on the connector 10 to replace the light emitting element 33 blocked by the connector 10, display uniformity is improved.

[0095] In some embodiments, the first side wall 122 has a light-transmitting area 100; the light-transmitting area 100 penetrates the first side wall 122 along the first direction x1 and the second direction y1; when the connection contact 11 and the electrode contact 31 are in abutment, the light-transmitting area 100 avoids the light-emitting element 33, or at least one light-emitting element 33 is located in the light-transmitting area 100.

[0096] The first sidewall 122 may be made of a transparent material to form the light-transmitting area 100 , or may be hollowed out to form the light-transmitting area 100 .

[0097] Illustratively, the first sidewall 122 is etched to form the light-transmitting area 100 to prevent the light-emitting element 33 in the groove 121 from colliding with the first sidewall 122 and causing wear during the process of clamping the light bar 30 .

[0098] When the connecting contact 11 and the electrode contact 31 are in contact, the light-transmitting area 100 is arranged to avoid the light-emitting element 33, that is, the first side wall 122 is located on the side of the light-emitting element 33 along the third direction z1 (see Figure 16 and Figure 17 ).

[0099] The light emitting element 33 is located in the light-transmitting area 100 (see Figure 13 etc.), to prevent the first sidewall 122 from occupying the space between the light emitting elements 33, thereby increasing the spacing between the light emitting elements 33 and affecting the light emitting effect.

[0100] In some embodiments, the connecting contact 11 may extend to the light-transmitting region 100 .

[0101] See also Figures 22 to 25 , Figure 22 is a structural diagram of the nineteenth embodiment of the light-emitting device provided in this application, Figure 23 is a structural diagram of the twentieth embodiment of the light-emitting device provided in this application, Figure 24 This is a structural diagram of an embodiment of a light bar and a connector provided by this application. Figure 25 This is a structural diagram of another embodiment of the light bar and connector provided in this application.

[0102] In some embodiments, as Figure 22As shown, a mounting groove 54 is provided on the side of the circuit board 32 of the light bar 30 facing the first side wall 122, and the electrode contact 31 is provided on the bottom wall of the mounting groove 54. When the light bar 30 is inserted into the groove body 121, the connection contact 11 corresponds to the position of the electrode contact 31. That is, the electrode contact 31 is embedded in the first side wall 122 and abuts against the connection contact 11. When the carrier 20 moves toward the first side wall 122, the connection contact 11 and the electrode contact 31 approach each other, and the connection contact 11 continuously approaches the mounting groove 54 and is inserted into the mounting groove 54, and abuts against the electrode contact 31. The mounting groove 54 limits the displacement of the light bar 30 in the third direction z1, and also makes the abutment between the connection contact 11 and the electrode contact 31 more stable, which is beneficial to the electrical connection stability of the light bar 30.

[0103] In other embodiments, the mounting groove 54 is disposed on the side of the first side wall 122 of the main body 12 facing the second side wall 123 , and the connecting contact 11 is disposed on the bottom wall of the mounting groove 54 to play the same limiting role.

[0104] In some embodiments, as Figure 23 As shown, the light-emitting device 1 further includes a magnetic member 55 and a magnetic member 56. One of the magnetic member 55 and the magnetic member 56 is disposed on the light bar 30, and the other is disposed on the connector 10. The light bar 30 is positioned by the mutual attraction between the magnetic member 55 and the magnetic member 56 so that the electrode contact 31 of the light bar 30 can be arranged opposite to the connection contact 11 in the second direction y1, ensuring that the electrode contact 31 and the connection contact 11 can abut against each other to achieve a good electrical connection.

[0105] In other embodiments, Figure 24 and Figure 25 As shown, in a direction parallel to the carrier board 20, the cross-section of the connector 10 is a trapezoid, with the upper and lower bases of the trapezoid arranged opposite each other along the first direction x1. The width of the light bar 30 along the third direction z1 gradually decreases along the first direction x1. The width of the upper base is smaller than the width of the lower base, so that when the light bar 30 is inserted into the slot 121 of the connector 10 along the first direction x1, the end of the light bar 30 with a smaller width passes through the lower base, passes through the upper base, and is locked in the slot 121. The upper base can be used to limit the insertion of the light bar 30, so that the electrode contact 31 of the light bar 30 can be accurately inserted into the preset position of the slot 121, so that the electrode contact 31 and the connection contact 11 are arranged opposite each other in the second direction y1, ensuring that the electrode contact 31 and the connection contact 11 can abut and achieve a good electrical connection.

[0106] For example, the connector 10 has a right-angled trapezoidal cross-section parallel to the carrier board 20, and the light bar 30 has a matching right-angled trapezoidal cross-section. The right-angled sides of the right-angled trapezoid are arranged along the first direction x1. Designing the connector 10 as a right-angled trapezoidal cross-section limits the light bar 30 in the third direction z1, facilitating stability during insertion of the light bar 30 through the slot 121.

[0107] The connector 10 further includes external contacts 13 , through which the connector 10 is electrically connected to an external power source.

[0108] Exemplarily, the external contact 13 is disposed outside the slot body 121 to facilitate connection with an external power source.

[0109] In other embodiments, the external contacts 13 may also be provided on the outer wall of the connector 10 . There are no excessive restrictions here and the selection is made according to actual needs.
