[0024] As Figures 1 to 5As shown, when the LED panel lamp is arranged in an embedded manner in the ceiling or wall, the heat dissipation plate 4 of the LED panel lamp is arranged in the ceiling or wall, and the probability of contacting dust is relatively small, and dust is not easy to accumulate. However, when the LED panel lamp is installed through a support or a hanging line, the heat dissipation plate 4 is exposed to the air and in contact with the air, and dust is easy to accumulate. If the dust on the heat dissipation plate 4 is not cleaned, the heat dissipation effect of the heat dissipation plate 4 will be affected, and the LED panel lamp cannot work stably. Therefore, a LED panel lamp with a heat dissipation plate 4 that can be quickly disassembled and installed is needed.

[0025] The present application relates to a LED panel lamp with a heat dissipation plate 4 that can be easily disassembled, which has a clever structure design and can effectively solve the problem of inconvenient disassembly of the heat dissipation plate 4 in the prior art. The specific technical solution is as follows:

[0026] The LED panel lamp comprises a lamp shell 1 in the shape of a flat plate, a plurality of LED lamp strips 2 arranged in the lamp shell 1, and a light-transmitting cover plate 15 for protecting the LED lamp strips, and a plurality of LED lamp beads are arranged on each LED lamp strip 2. In order to improve the heat dissipation performance, a heat dissipation plate 4 is arranged at the back of the lamp shell 1, and guide rails 3 are arranged on both sides of the back of the lamp shell 1. The heat dissipation plate 4 is arranged at the back of the lamp shell 1 in an inserted manner through the guide rails 3. This inserted design not only simplifies the installation and disassembly process of the heat dissipation plate 4, but also avoids the cumbersome operation caused by the traditional screw fixing method.

[0027] The LED panel lamp further comprises a fixing assembly for fixing the heat dissipation plate 4, and the fixing assembly comprises a pressing rod 5 and a spring 6. The guide rail 3 is provided with a guide cylinder 7, the lower end 8 of the pressing rod 5 is arranged in the guide cylinder 7, and the upper end 9 is arranged at the top of the guide cylinder 7. The bottom of the lower end 8 of the pressing rod 5 is provided with a push block 10, and the spring 6 is located in the guide cylinder 7 and is sleeved on the lower end 8 of the pressing rod 5, between the push block 10 and the top of the guide cylinder 7. This unique fixing assembly design, through the cooperation of the pressing rod 5 and the spring 6, realizes the quick fixing and releasing of the heat dissipation plate 4. The user only needs to pull up the pressing rod 5 to easily take out the heat dissipation plate 4 from the lamp shell 1, without using any tools, greatly improving the cleaning efficiency of the heat dissipation plate 4.

[0028] The two sides of the heat dissipation plate 4 are located between the lamp shell 1 and the push block 10 respectively, and the push block 10 presses the heat dissipation plate 4 under the action of the spring 6, so that the heat dissipation plate 4 is tightly attached to the back of the lamp shell 1, improving the heat conduction capacity of the heat dissipation plate 4, and thus improving the heat dissipation effect.

[0029] As one of the embodiments, the two ends of the guide rail 3 are provided with a fixing assembly. This design further enhances the fixing stability of the heat dissipation plate 4, and at the same time provides double protection to prevent the heat dissipation plate 4 from loosening or falling off during use.

[0030] As one of the embodiments, the top of the guide cylinder 7 is provided with a circular hole 11, the diameter of the upper end 9 of the pressing rod 5 is greater than the diameter of the circular hole 11, and the diameter of the lower end 8 of the pressing rod 5 is less than or equal to the diameter of the circular hole 11. In this way, the lower end 8 of the pressing rod 5 can extend out of the guide cylinder 7, and the upper end 9 of the pressing rod 5 can be prevented from being retracted into the guide cylinder 7.

[0031] As one of the embodiments, the lower end 8 of the pressing rod 5 is fixed to the push block 10 by screwing. This threaded connection is not only firm and reliable, but also facilitates the disassembly and replacement of the push block 10, further improving the maintenance convenience of the product.

[0032] As one of the embodiments, the push block 10 is in the shape of a disc, and the diameter of the disc-shaped push block 10 is less than or equal to the diameter of the circular hole 11. This design allows the push block 10 to move smoothly in the guide cylinder 7, so that the pressing rod 5 can install heat dissipation plates 4 of different thicknesses on the back of the lamp shell 1.

[0033] As one of the embodiments, the guide rail 3 includes vertical blocks 12 and horizontal blocks 13, the bottom of the vertical block 12 is integrally arranged with the back of the lamp shell 1, the top and the horizontal block 13 are integrally arranged, and the guide cylinder 7 is arranged on the top of the horizontal block 13. This integrated design not only improves the structural strength of the guide rail 3, but also simplifies the production process and reduces the production cost.

[0034] As one of the embodiments, one side of the back of the lamp shell 1 is provided with a limiting block 14, which is used to limit the heat dissipation plate 4 between the guide rails 3. This limiting design can effectively prevent the heat dissipation plate 4 from being inserted from one side of the guide rail 3 and falling off from the other side. When the LED flat panel lamp is vertically or obliquely arranged, the limiting block 14 can also support the heat dissipation plate 4.

[0035] As one of the embodiments, the horizontal cross section of the lamp shell 1 is in a square structure. This square structure not only looks beautiful and elegant, but also better adapts to various installation environments, while ensuring uniform heat dissipation of the heat dissipation plate 4 and improving the overall performance of the LED flat panel lamp.

[0036] Through the cooperation of the pressing rod 5 and the spring 6, and the plug-in design, the disassembly and installation of the heat dissipation plate 4 become extremely simple, without the need for tools, greatly improving the cleaning and maintenance efficiency of the heat dissipation plate 4.

[0037] The heat dissipation plate 4 is easy to disassemble and clean, which can effectively remove dust and restore the heat dissipation performance, thereby prolonging the service life of the LED flat panel lamp and maintaining its stability and light efficiency in long-term use.

[0038] Adopt the fixed assembly of pressing rod 5 and spring 6, simplify the fixed mode of heat dissipation plate 4, avoid the cumbersome operation and potential loose problem of traditional screw fixed mode, improve the reliability and durability of product.

[0039] Users can easily disassemble and install the heat dissipation plate 4, reduce the maintenance cost and time cost, improve the product use experience, especially suitable for places with high maintenance convenience requirements.

[0040] The design of plug-in and the integrated guide rail 3 structure realize the quick disassembly function of the heat dissipation plate 4 without increasing additional space, while maintaining the overall aesthetics of the lamp.

[0041] By setting the fixed assembly at both ends of the guide rail 3 and the design of the limiting block 14, the fixing stability of the heat dissipation plate 4 is further enhanced, preventing the heat dissipation plate 4 from loosening or falling off during use, ensuring the reliability and safety of the product.

[0042] In summary, the present application solves the problem of inconvenient disassembly of the heat dissipation plate 4 of the existing LED flat lamp through innovative structural design, significantly improves the maintenance efficiency and heat dissipation performance of the heat dissipation plate 4, simplifies the structure, improves the user experience and product reliability, and has significant technical progress and practical value.
