The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, a lighting device includes a strip-shaped lampshade 1, a connector 5, and at least two screws 6. The lampshade 1 is a hollow structure with one open end. At least two screw holes 21 are formed along its axial direction at the open end of the lampshade 1. The screw holes 21 are distributed circumferentially around the lampshade 1. An lighting component 7 for emitting light is disposed inside the lampshade 1. The rear end of the connector 5 blocks the opening of the lampshade 1. At least two through holes 51 are formed along its axial direction at the front end of the connector 5. The through holes 51 are distributed circumferentially around the connector 5 and correspond one-to-one with the screw holes 21. A plug 52 is provided at the front end of the connector 5. The plug 52 is electrically connected to the lighting component 7. The screws 6 are inserted one by one. The head of the screw 6 abuts against the front end of the connector 5, and its tip is screwed into the corresponding screw hole 21. Based on the connection between the lampshade 1 and the connector 5 through plug-in and glue bonding, the screw 6 is used to connect the lampshade 1 and the connector 5. The screw 6 increases the number of connection points between the lampshade 1 and the connector 5, which can help the rear end of the connector 5 to share the force generated by the weight of the lampshade 1 and the lighting component 7, improve the connection strength between the connector 5 and the lampshade 1, and at the same time prevent the lampshade 1 and the connector 5 from easily loosening due to glue failure, improve the connection reliability between the lampshade 1 and the connector 5, and reduce the risk of the lampshade 1 falling off.

[0028] Specifically, the lampshade 1 can be a fully transparent or partially transparent structure, which is not limited in this embodiment.

[0029] Furthermore, three screw holes 21 are provided and are asymmetrically distributed circumferentially around the axis of the lampshade 1. When the lampshade 1 is installed horizontally, the side with screw holes 21 faces upward. After the end of this side wall is fixed to the connector 5 by screws 6, the same end of the lower side wall of the lampshade 1 will abut against the end wall of the connector 5, so as to provide additional support for the lampshade 1 through the connector 5, avoid the lampshade 1 from breaking due to torque at the connection between the screws 6 and the connector 5, and improve the installation stability of the lampshade 1.

[0030] Furthermore, the rear end of the connector 5 is provided with a plug-in part 53, and the open end of the lamp cover 1 is provided with a slot 11 for the plug-in part 53 to be inserted along the axial direction. By inserting the plug-in part 53 into the slot 11, not only can additional support be provided for the lamp cover 1, but it is also convenient to position the connector 5 and the open end of the lamp cover 1, making it easy to align the through hole 51 and the screw hole 21, and reducing the difficulty of installation.

[0031] Furthermore, at least two clearance grooves 54 are distributed on the periphery of the connector 5. The clearance grooves 54 are arranged along the axial direction of the connector 5 and connect to the front end of the connector 5. Through holes 51 are correspondingly opened on the end wall of the clearance grooves 54. In use, the screw 6 can be inserted into the through hole 51 through the clearance grooves 54. The head of the screw 6 abuts against the end wall of the clearance groove 54, and the tip of the screw 6 is screwed into the corresponding screw hole 21 so that the head of the screw 6 can be accommodated by the clearance grooves 54. At the same time, it is beneficial to shorten the length of the screw 6 required to connect the lamp cover 1 and the connector 5, thereby improving economic efficiency.

[0032] Furthermore, the lighting component 7 is a lamp plate, which is arranged along the length of the lamp cover 1. Several lamp beads are evenly distributed on the lamp plate along its length. The inner walls on both sides of the lamp cover 1 are provided with second slots 22 that connect to their openings along their length. The lamp plate is inserted into the second slots 22 so as to fix the lamp plate in the lamp cover 1 through the second slots 22.

[0033] Furthermore, the rear end of the connector 5 is provided with a first slot 55 that penetrates both sides of its axial direction. The front end of the lamp board is inserted into the first slot 55 to connect the lamp board and the connector 5 through the first slot 55. The middle part of the connector 5 provides additional support for the lamp board, distributing part of the weight of the lamp board to the middle part of the connector 5, making the force on the connector 5 more uniform and improving the stability of the connection.

[0034] Furthermore, the lampshade 1 is composed of an upper tube 2, a lower tube 3 made of light-transmitting material, and a tail cap 4. Screw holes 21 are set on the corresponding end wall of the upper tube 2 and are evenly distributed along the circumference of the upper tube 2. Through holes 51 and screws 6 are set one-to-one with screw holes 21. There are two slots 11, which are respectively set at the ends of the upper tube 2 and the lower tube 3. The plug-in part 53 corresponds one-to-one with the slot 11 so that the plug-in part 53 can be plugged into the slot 11 one-to-one, providing additional support for the connection between the upper tube 2 and the lower tube 3. The lampshade 1 is divided into three parts to facilitate the assembly of the lighting device. When in use, the upper tube 2 is located above the lower tube 3. When the end of the upper tube 2 is connected to the connector 5 by the screw 6, the end of the lower tube 3 abuts against the end of the connector 5. The principle is the same as above. The light emitted by the lamp panel will be emitted through the lower tube 3 to illuminate the indoor space.

[0035] Specifically, the upper tube 2 and the lower tube 3 can be symmetrical or asymmetrical structures.

[0036] Furthermore, the inner walls of the two ends of the upper pipe 2 are provided with sliding grooves 23. The sliding grooves 23 are arranged along the axial direction of the upper pipe 2 and are connected to at least one end of the upper pipe 2. The two ends of the lower pipe 3 are symmetrically provided with sliding joints 31 whose contours are adapted to the sliding grooves 23. The sliding joints 31 can be slidably inserted through the open end of the sliding grooves 23, so that the lower pipe 3 and the upper pipe 2 can be detachably enclosed.

[0037] Furthermore, both the screw hole 21 and the slot 11 extend through the rear end of the upper tube 2. The tail cover 4 is also provided with a plug-in part 53. A screw 6 is fitted onto the tail cover 4 corresponding to the screw hole 21. The tip of the screw 6 is screwed into the screw hole 21, so that the tail cover 4 is detachably and axially fixed to the rear end of the upper tube 2. The plug-in part 53 will be plugged into the slot 11 on the upper tube 2 and the lower tube 3 respectively, so as to connect the front end of the upper tube 2 and the rear end of the lower tube 3 through the connector 5 and the tail cover 4 respectively, thereby improving the assembly stability of the upper tube 2 and the lower tube 3.

[0038] Furthermore, the lighting device also includes a mounting base 8, a hanging rod 81, and a socket 82. The mounting base 8 is used to connect to the wall. One end of the hanging rod 81 is fixedly connected to the mounting base 8. The socket 82 is fixedly connected to the other end of the hanging rod 81. The end of the socket 82 is provided with a receiving cavity 83. The front end of the connector 5 can be inserted into the receiving cavity 83 to make the plug 52 electrically connected to the socket 82 so that the socket 82 can supply power to the lamp panel through the plug 52. At the same time, the quick-release connection between the connector 5 and the socket 82 also makes it easy for users to remove the lamp cover 1 to inspect or replace the lamp panel, reducing the difficulty of later maintenance.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
