Implementation

[0017] The lamp connector, the lamp and the lighting system formed by the lamp connector provided in the present invention are further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The structure of the lamp connector 1 in a preferred embodiment of the present application is as follows Figure 1 As shown, in this embodiment, the lamp connected to the lamp connector 1 is a light bar 2. Figure 2 As shown. The lamp connector 1 includes a columnar main body 11. A first groove 13 and a second groove 14 are provided on the outer peripheral side of the main body 11. In this embodiment, the main body 11 is cylindrical, and the first groove 13 and the second groove 14 are both annular and surround the outer side of the main body 11. The first groove 13 and the second groove 14 are provided along the axial direction of the main body 11, and the notches of the two are opposite, and there is a certain interval between the notch 1302 of the first groove 13 and the notch 1402 of the second groove 14, forming a connection opening 15.

[0019] The first groove 13 is a mechanical connection part of the lamp connector 1, and its groove bottom extends outward from the main body 11, and the outer groove wall 1301 is annular and coaxially arranged with the main body 11. Figure 1 As shown, in this embodiment, the bottom of the first groove 13 is exactly arranged on the end surface of the main body 11. In other preferred embodiments, the bottom of the first groove 13 can also extend outward from the middle position of the main body 11, and this is not limited in this application. A connecting portion 22 is arranged at the end of the light bar 2 to match the first groove 13. The light bar 2 is a strip-shaped light source, and end caps 21 are arranged at both ends. Figure 5 , Figure 6 The connecting portion 22 is shown to be disposed on the outside of the end cap 21. In other embodiments, the lamp may also be other structures, such as a light bulb, a plate-shaped light source module lamp, and the connecting portion 22 can be disposed at any end of the lamp. The connecting portion 22 includes a supporting portion 2201 extending outward from the end of the lamp 2, and a first plug-in block 2202 disposed on the supporting portion 2201 and extending toward one side, and the support portion 2201 and the first plug-in block 2202 are combined to form an "L" shape. When the light bar 2 and the lamp connector 1 are connected, the first plug-in block 2202 is inserted into the first groove 13, the supporting portion 2201 is disposed in the connecting opening 15, and the lamp body of the light bar 2 radiates outward from the lamp connector 1 along the supporting portion 2201.

[0020] Since the first groove 13 is annular, the light bar 2 can be set at any position on the cylindrical outer circumference of the main body 11, and the end of the light bar 2 can be rotated along the outer circumference of the main body 11 to change its position. If the outer circumference space can accommodate multiple light bars 2, the light bars 2 can be connected in a radial shape with the light bar connector 1 as the center, such as Figure 7 In other preferred embodiments, the main body may also be a columnar body in other forms, such as a triangular prism, or a prism with a regular polygonal cross section, etc. In this way, although the connection positions between the light bar 2 and the light bar connector 1 are not as many as those of a cylinder, they can still be connected to the surfaces of the prism, realizing more connection combinations than conventional connectors.

[0021] In addition to being mechanically connected to the light bar 2, the light bar connector 1 also needs to be electrically connected to the light bar 2 to ensure the normal operation of the light bar 2. In previous solutions, the light bar 2 usually includes an electrical connection terminal 23, and the connector is provided with a terminal plug interface that matches the shape of the electrical connection terminal 23, and the electrical connection terminal 23 is inserted to achieve electrical connection. In the present application, since the number and position of the light bar 2 are not fixed, conventional plug interfaces cannot meet the requirements. In the light bar connector 1 provided in the present application, the second groove 14 is the electrical connection part, and the conductive component 16 is arranged in the second groove 14. The second groove 14 is also annular, including a groove bottom and an outer groove surface 1401. The conductive component 16 includes an insulating strip 1601 laid on the bottom of the second groove 14, and its specific structure is as follows Figure 3 , Figure 4 As shown, the conductive electrodes are arranged on the insulating strip 1601, and the insulating strip 1601 is provided with three conductive electrodes, namely, the live conductive electrode 1602, the ground conductive electrode 1604, and the neutral conductive electrode 1603. In order to insulate and isolate the three electrodes, the insulating strip 1601 is provided with some convex strips 1605 protruding toward the notch 1402 of the second groove 14, and the three electrodes are respectively arranged on different sides of the convex strip 1302. The number and setting position of the electrodes can be set according to specific connection requirements, such as adding another data line, or setting multiple convex strips 1605 for insulation isolation, which is not limited in this application. The shape of the insulating strip 1301 and the conductive electrode is consistent with the second groove 14, and is also annular. After the electrical connection terminal 23 is inserted into the second groove 14 through the notch 1402 of the second groove 14, it can form an electrical connection with any point on the annular conductive electrode. This design breaks through the position limitation of the original fixed plug interface. The overall annular conductive component 16 and the annular opening 18 can accept the insertion of multiple electrical connection terminals 201 of multiple light strips 2, and electrical connection can be achieved at any point on the ring, so there is no need to consider the connection position of the light strip 2.

[0022] In some preferred embodiments, the electrical connection terminal 23 is connected to the light bar 2 through a wire, but this method is not aesthetically pleasing, and when many light bars 2 are connected to the lamp connector 1, the wires are easily tangled and difficult to assemble. Therefore, this embodiment provides a more concise and easy-to-assemble connection structure. Figure 5 , Figure 6 As shown, a second plug-in block 2203 for matching with the second groove 14 is also provided on the connecting portion 22, and the second plug-in block 2203 extends from the supporting portion 2001 in a direction away from the first plug-in block 2202. The electrical connection terminal 23 is provided at the end of the second plug-in block 2203. When the second plug-in block 2203 is inserted into the second groove 14, the electrical connection terminal 23 is inserted facing the groove bottom direction of the second groove 14, and contacts with the conductive component 16 to form an electrical connection. The structure of the electrical connection terminal 23 is adapted to the conductive component 16, including a live wire conductive contact 2302, a ground wire conductive contact 2304, and a neutral wire conductive contact 2303. At the same time, in order to match the annular second groove 14 with the annular conductive component 16, the terminal head of the electrical connection terminal 23 is arc-shaped, and after being inserted into the second groove 14, it can slide along the second groove 14.

[0023] The connecting portion 22 is in a T-shape as a whole. Figure 2As shown, after the first plug-in block 2202 is inserted into the first groove 13 and the second plug-in block 2203 is inserted into the second groove 14, the support portion 2201 is arranged in the connection opening 15 between the outer groove wall 1301 of the first groove 13 and the outer groove wall 1402 of the second groove 14. The connection portion 22 of the "T"-shaped structure cannot be directly inserted into the first groove 13 and the second groove 14 through the connection opening 15 to achieve connection. The lamp connector 1 also includes a cover body 12 arranged on one side of the end of the main body 11, and the cover body 12 and the main body 11 are detachably connected. In this embodiment, the second groove 14 is formed on the cover body 12, and the cover plate 1201 of the cover body 12 forms the groove bottom of the second groove 14, and the outer side of the cover plate 1201 extends toward the main body 11 to form the outer groove wall 1402 of the second groove 14. A threaded connection structure 1202 protrudes from the middle part of the cover body 12 and is threadedly connected to the main body 11.

[0024] When assembling the light bar 2 and the lamp connector 1, first insert the first plug-in blocks 2202 of the plurality of light bars 2 into the first groove 13, then cover the cover 12 so that the second groove 14 covers the second plug-in block 2203, and after the cover is tightened, the electrical connection terminal 16 fits the conductive component 16, and the light bar 2 and the lamp connector 1 are connected. This connection method is simple and reliable, and can achieve mechanical connection and electrical connection at the same time. Moreover, since the first groove 13 and the second groove 14 are both annular, the connecting portion 22 can be set at any position of the annular shape, and can accommodate multiple connecting portions 22 at the same time, so as to achieve a flexible combination of multiple lamps. In other preferred embodiments, the first groove 13 can also be set on the cover 12, and the second groove 14 can be set on the main body 11, as long as the first groove 13 and the second groove 14 are respectively set on two detachably connected parts. As for the connection method, other detachable connection methods such as snaps and screws can also be used, and this application does not limit this.

[0025] The lamp connector 1 of the above embodiment can be used to connect multiple light strips 2 to form a lighting system. Figure 7 What is shown is a schematic diagram of the structure of a connection node in a lighting system. Four light strips 2 are connected to the lamp connector 1, and the ends of the light strips 2 are connected to the outer peripheral side of the lamp connector 1. The two ends of the connecting portion 22 of each light strip 2 are respectively inserted into the annular first groove 13 and the second groove 14, thereby realizing electrical connection and mechanical connection at the same time. After the light strip 2 and the light strip connector 1 are connected, the connecting portion 22 can be rotated and moved along the outer peripheral surface of the main body 11 in the first groove 13 and the second groove 14, and the light strip 2 can be rotated and moved along the outer peripheral surface of the lamp connector 1. For the convenience of installation and positioning, in the present embodiment, the surface of the end face 1101 of the main body 11 is still provided with an angle scale, which can facilitate the angle setting between adjacent light strips 2.

[0026] In order to keep each light bar 2 in a relatively fixed position after the light bar 2 and the light fixture connector 1 are assembled, a protrusion 2204 protruding toward the end cover 21 is further provided on the first plug block 2202. When the light bar 2 and the light fixture connector 1 are connected, the outer groove wall 1301 of the first groove 13 is clamped by the protrusion 2204 and the end of the light bar 2. The friction provided by the clamping can prevent the light bar 2 from moving easily, so that it always remains in the position when the installation is completed.

[0027] In other preferred embodiments, the lamp can also be a light source module of various forms with one end being a connection end. Each module can have different shapes, and after being combined with the lamp connector 1, a structure similar to a chandelier can be formed, and each light source module is a lamp arm of various forms. In another preferred embodiment, the lamp can also be a track light, which includes a track and a lighting unit arranged on the track. A connection structure similar to the end cap 21 of the light bar 2 is arranged at the end of the track to achieve mechanical and electrical connection with the lamp connector 1, and the lighting unit is connected to the track through a connector. Multiple tracks and lamp connectors 1 can realize the installation of various forms of tracks.

[0028] The above description of the preferred embodiments of the present application is for illustration and description, and is not intended to be exhaustive or limited to the specific form disclosed. Obviously, many modifications and changes may be made, which may be obvious to those skilled in the art and should be included in the scope of the present application defined by the attached claims.
