The lamp holder 2 is provided with a cavity 4 that can accommodate the limiting edge 3. The bottom of the lamp holder 2 is provided with several arrayed heat dissipation holes 13. Through the cooperation of the limiting edge 3 and the inner wall of the cavity 4, the lampshade 1 and the lamp holder 2 can achieve initial fixation and limitation. The setting of the heat dissipation holes 13 helps to dissipate heat quickly and extend the service life of the lamp. Since both the lampshade 1 and the lamp holder 2 are made of plastic, the overall weight of the lamp is light, making it easy to install and transport. In addition, the plastic material has good transparency and light transmittance, which can ensure the lighting effect of the lamp.

[0025] Specifically, the outer wall of the limiting edge 3 is provided with a limiting ring 5, the inner wall of the accommodating cavity 4 is provided with a limiting groove 6 for accommodating the limiting ring 5, the limiting ring 5 separates the limiting edge 3 into a limiting part one 8 and a limiting part two 9, the diameter of the limiting part one 8 is smaller than that of the limiting part two 9, the inner wall of the accommodating cavity 4 is provided with an arc-shaped protrusion 7 which is located above the limiting groove 6, when the limiting ring 5 is embedded in the limiting groove 6, the arc-shaped protrusion 7 abuts against the outer wall of the limiting part one 8, through the setting of the limiting ring 5, the limiting groove 6 and the arc-shaped protrusion 7, the double limiting structure makes the connection of the lampshade 1 and the lamp holder 2 more firm, avoids loosening or falling off caused by external force or vibration, and the design of the limiting ring 5 and the limiting groove 6 makes the assembly of the lampshade 1 and the lamp holder 2 more intuitive and fast, only needs to insert the limiting edge 3 into the accommodating cavity 4, the limiting ring 5 is naturally embedded in the limiting groove 6, the scheme does not need to use glue to fix, simplifies the assembly process, reduces the requirement for the technical proficiency of the operator, thereby shortens the assembly time and improves the production efficiency, because the arc-shaped protrusion 7 abuts against the outer wall of the limiting part one 8, the structure design makes the limiting edge 3 receive uniform force in the long-term use process, reduces local wear and tear, and prolongs the service life.

[0026] Further, the arc-shaped protrusion 7 is integrally formed on the inner wall of the accommodating cavity 4, the lampshade 1, the limiting edge 3 and the limiting ring 5 are integrally formed, the integral forming can improve the connection strength between the arc-shaped protrusion 7 and the inner wall of the accommodating cavity 4, also ensures the firmness and durability of the limiting edge 3 and the limiting ring 5 in the disassembly process of the lampshade 1, reduces the connection gap between parts, avoids loosening or falling off caused by improper assembly or long-term use, also reduces the number of parts and production links, reduces material waste and the rate of defective products.

[0027] The inner wall of the accommodating cavity 4 is provided with a supporting ring 10, when the limiting ring 5 is embedded in the limiting groove 6, the bottom surface of the limiting edge 3 abuts against the top surface of the supporting ring 10, a plurality of reinforcing ribs 11 are arranged between the outer wall of the supporting ring 10 and the inner wall of the accommodating cavity 4, through the above setting, stable support is provided for the lampshade 1, preventing it from loosening due to external force or vibration in the use process, the reinforcing ribs 11 are arranged between the outer wall of the supporting ring 10 and the inner wall of the accommodating cavity 4, can effectively disperse the load, improve the rigidity and strength of the overall structure, reduce stress concentration, at the same time, through enhancing the structural strength, reduce fatigue damage caused by stress concentration, thereby prolonging the service life of the lamp shell.

[0028] The arc-shaped protrusion 7 and the top surface of the lamp holder 2 are provided with a guide surface 12, the guide surface 12 is arranged in an inclined manner, the inclined guide surface 12 can guide the limiting edge 3 to smoothly enter the accommodating cavity 4, reduce the alignment difficulty in assembly, make the assembly process more smooth, at the same time, the inclined guide surface 12 can ensure that the limiting edge 3 receives uniform force when entering the accommodating cavity 4, reduce deformation or damage caused by local excessive force, help to disperse stress, improve the stability and durability of the overall structure.

[0029] The inner wall of the lamp holder 2 is provided with four abutting tabs 14 arranged along the circumference of the inner wall of the lamp holder 2, one end of the abutting tabs 14 is fixed on the inner wall of the lamp holder 2, and the other end of the abutting tabs 14 is arranged towards the lampshade 1. When the two sides of the lamp holder 2 are close to each other, one end of the abutting tabs 14 abuts against the inner wall of the lampshade 1. By arranging the abutting tabs 14, when the lampshade 1 is disassembled, the operator only needs to apply force to the two sides of the lamp holder 2, at this time, the abutting tabs 14 will be close to the lampshade 1 and abut against the inner wall of the lampshade 1. With the continuous force applied by the operator, the lampshade 1 will be separated from the lamp holder 2, thereby completing the disassembly. Through the above arrangement, when the lampshade 1 is disassembled, no screwdriver, crowbar or other tools are needed, the operation process is simplified, and the disassembly can be completed with a single force, which is especially suitable for narrow space or high-altitude operation scenes, and improves the operation convenience.

[0030] The above is only the preferred embodiment of the present application, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solution belonging to the idea of the present application is within the protection scope of the present application. It should be noted that for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
