The other side of the shell 1 is provided with a mounting opening, which is used for the functional accessory 2 to play an effect. The side surface of the shell 1 is provided with a circumferential heat dissipation opening, which corresponds to the heat dissipation plate 7, provides additional heat dissipation space for the lamp, further improves the heat dissipation effect, and avoids overheating.

[0029] The lighting plate assembly 6 is located in the containing cavity of the shell 1, and the light exit surface faces the light exit opening, which is used for improving the lighting light source. The lighting plate assembly 6 cooperates with the light exit opening of the shell 1, ensures the large-area light output, and can provide uniform and extensive illumination.

[0030] The heat dissipation plate 7 is installed on the non-light-emitting surface of the lighting assembly and is provided with heat dissipation channels 703 for guiding and quickly discharging the heat generated during the lighting process. The heat dissipation channels 703 correspond to the heat dissipation openings of the shell 1, through which effective heat dissipation is achieved, thereby enhancing the heat dissipation effect and preventing the lamp from being affected in performance or service life due to high temperature. As an optional embodiment, the heat dissipation plate 7 is made of aluminum material to improve the heat dissipation performance.

[0031] The functional accessory 2 can enhance the performance of the lamp, and the functional accessory 2 is arranged at the middle part of the heat dissipation plate 7.

To realize this mode, a power supply interface and a mounting structure matched with the heat dissipation plate 7 need to be arranged on the heat dissipation plate 7.

[0033] As an optional embodiment, as shown in Figure 5 , the middle part of the heat dissipation plate 7 is provided with a mounting groove 701 corresponding to the mounting opening, for mounting the functional accessory 2; the heat dissipation plate 7 is uniformly provided with heat dissipation ribs 702 extending outward from the edge of the mounting groove 701, and the heat dissipation channels 703 are formed between adjacent heat dissipation ribs 702.

[0034] The middle part of the heat dissipation plate 7 is provided with a mounting groove 701 corresponding to the mounting opening of the shell 1, for mounting the functional accessory 2. This structure ensures that the functional accessory 2 (such as the fan assembly 201 or the light source assembly 202) can be conveniently connected with the heat dissipation plate 7 and can be fixed or disassembled through the mounting groove 701. The correspondence between the mounting groove 701 and the mounting opening enables the functional accessory 2 to be accurately positioned and function. For example, the fan assembly 201 can draw air through the mounting opening, and the light source assembly 202 can illuminate out of the mounting opening.
