[0026] Reference Figure 1 A panel light includes a lamp holder 100, a lamp shade 200, and a light source assembly. The lamp holder 100 is disposed on its bottom side. A metal strip 210 is disposed between the lamp holder 100 and the lamp shade 200. The metal strip 210 can be a linear structure or a strip structure. A heat-fused bonding layer 220 is formed between the lamp holder 100 and the lamp shade 200. A cavity is formed between the lamp holder 100 and the lamp shade 200. The light source assembly is located in the cavity and can emit light towards the lamp shade 200. In practical applications, in order to make it easier to form the heat-fused bonding layer 220 between the lamp holder 100 and the lamp shade 200, both can be made of materials with low melting points, such as plastic.

[0027] As described above, when assembling the lamp holder 100 and the lampshade 200, the light source component is installed in the cavity formed between the lamp holder 100 and the lampshade 200, and the metal strip 210 is placed between the lamp holder 100 and the lampshade 200. Then, using equipment such as a high-frequency induction welding machine, high-frequency induction heating based on the principle of electromagnetic induction is used to generate induction heating on the metal strip 210 located between the lamp holder 100 and the lampshade 200, so that the position where the lamp holder 100 and the lampshade 200 abut against the metal strip 210 melts to form a heat-fused bonding layer 220, thereby tightly connecting the lamp holder 100 and the lampshade 200 without any exposed connection structure. When in use, the light source component emits light towards the lampshade 200 from within the cavity to achieve the lighting function. This avoids the impact of the connection structure on the overall appearance and tightly connects the lamp holder 100 and the lampshade 200, improving the waterproof performance and service life of the panel light.

[0028] The lampshade 200 may only have a bottom surface as the light-emitting surface. However, in order to improve the light emission effect, a light-emitting surface may also be formed on the outer periphery of the lampshade 200. Specifically, an upwardly protruding connecting periphery 230 is formed on the outer side of the lampshade 200. In practical applications, the connecting periphery 230 and the lampshade 200 are integrally formed. The connecting periphery 230 is connected to the bottom side of the lamp holder 100. The metal strip 210 is disposed between the connecting periphery 230 and the lamp holder 100. When the lampshade 200 is connected to the lamp holder 100, the connecting periphery 230 abuts against the lamp holder 100, and a metal strip 210 is placed at the contact position. Through high-frequency induction heating based on the principle of electromagnetic induction, the connecting periphery 230 and the lamp holder 100 melt at the contact position of the metal strip 210 to form a heat-fused bonding layer 220, thereby tightly connecting the lamp holder 100 and the connecting periphery 230. Applying a certain pressure to the lamp holder 100 and the connecting periphery 230 can cause the heat-fused bonding layer 220 to tightly fill the interface gap between the lamp holder 100 and the connecting periphery 230, thereby achieving a welding effect. In this way, the lampshade 200 can also form a light-emitting surface at the periphery position, improving the light emission effect.

[0029] To facilitate the storage and placement of the metal strip 210, a structure for storing the metal strip 210 can be added to the lamp holder 100 or the connecting periphery 230. Specifically, the lamp holder 100 has a receiving groove 110 on its bottom side, and the metal strip 210 is located in the receiving groove 110. The connecting periphery 230 has a mounting protrusion 231 on its top side corresponding to the position of the receiving groove 110. The mounting protrusion 231 is inserted into the receiving groove 110, and the hot-melt connection layer 220 is formed between the mounting protrusion 231 and the receiving groove 110. When assembling the lamp holder 100 and the lamp cover 200, the metal strip 210 can be placed into the receiving groove 110, and then the mounting protrusion 231 can be inserted into the receiving groove 110 to quickly position the metal strip 210 relative to the lamp holder 100 and the lamp cover 200. When the metal strip 210 is heated, the bottom and sidewalls of the receiving groove 110 are also heated. Correspondingly, the mounting protrusion 231 near the bottom and sidewalls of the receiving groove 110 is also heated, forming a heat-fused connection layer 220. In this way, connection points can be formed at multiple different locations, further increasing the total area of ​​the heat-fused connection layer 220 and improving the connection stability between the lamp holder 100 and the lamp cover 200.

[0030] In the above embodiments, the metal strip 210 and the receiving groove 110 can be disposed on any one side of the lamp holder 100 and the lamp cover 200, or on opposite sides. However, to ensure a tight and seamless connection structure on all four sides of the lamp holder 100 and the lamp cover 200, in this embodiment, the receiving groove 110 and the metal strip 210 are respectively disposed around the cavity. When the metal strip 210 is arranged around the receiving groove 110, a heat-fused bonding layer 220 is formed between the lamp holder 100 and the lamp cover 200 around the cavity, thus making the connection between the lamp holder 100 and the lamp cover 200 tighter and improving the connection stability.

[0031] In the above embodiment, the metal strip 210 can be positioned near the outer edge of the connecting periphery 230. When the metal strip 210 is heated, the outer edge of the connecting periphery 230 and the outer edge of the lamp holder 100 melt to form a heat-fused bonding layer 220. This heat-fused bonding layer 220 has poor smoothness, making it difficult to further improve the overall appearance. Therefore, the metal strip 210 can be positioned near the inner edge of the connecting periphery 230. Specifically, a connecting concave angle 232 is formed on the bottom side of the connecting periphery 230 outside the mounting protrusion 231, and a connecting protrusion 120 is formed on the bottom side of the lamp holder 100 outside the receiving groove 110. The connecting protrusion 120 is fitted into the connecting concave angle 232. When the metal strip 210 is heated, the portion of the connecting periphery 230 near the inner edge and the middle portion of the lamp holder 100 melt to form the heat-fused bonding layer 220, which is not exposed on the outer surface of the formed whole. This effectively ensures the flatness of the overall appearance and further improves the overall aesthetics.

[0032] To achieve a seamless connection between the lamp holder 100 and the connecting periphery 230, in this embodiment, the bottom outer edge of the connecting periphery 230 is connected to the top outer edge of the lamp holder 100. At this point, the bottom and top outer edges of the connecting periphery are tightly joined, forming a continuous appearance surface, which further enhances the overall effect.

[0033] As a specific implementation of the light source assembly, the light source assembly includes a drive plate 310 and light strips 320 connected to the inner top side of the lamp holder 100. The light strips 320 are electrically connected to the drive plate 310, and multiple light strips 320 are spaced apart in the horizontal direction. The drive plate 310 can provide power to drive the multiple light strips 320, so that the multiple light strips 320 work and emit light to the lamp cover 200.

[0034] Furthermore, the inner top side of the lamp holder 100 arches upward and forms a mounting groove 130, within which the drive plate 310 is connected. The arched structure of the inner top side of the lamp holder 100 improves its structural strength, preventing it from easily deforming under external forces. The arched portion also creates a space for the drive plate 310 to be installed, raising its installation height and moving it further away from the lamp cover 200. This effectively reduces the shadow cast by the drive plate 310 on the lamp cover 200, improving the light output efficiency.

[0035] In some embodiments, the lamp holder 100 is provided with snap-fit ​​strips 140 on both sides. When it is necessary to connect the lamp holder 100 to the structural components of an external device, the snap-fit ​​strips 140 on both sides of the lamp holder 100 can be snapped into the hook positions on both sides of the external device structural components, thereby quickly and securely fixing the lamp holder 100. In practical applications, there can be four snap-fit ​​strips 140, respectively provided on the four sides of the lamp holder 100.

[0036] To allow wiring to the drive board 310 inside the cavity, the lamp holder 100 needs to have holes on its outer side for wiring. Therefore, in this embodiment, a waterproof connector 150 is provided on the outer side of the lamp holder 100. External wires can pass through the waterproof connector 150 and be connected to the drive board 310 of the lamp holder 100. The waterproof connector 150 effectively reduces the intrusion of moisture into the cavity from the holes, thereby further improving the overall waterproof performance.
