[0002] Panel lights have been widely used in indoor and outdoor lighting scenarios due to their advantages such as soft light and uniform illumination. As the outer structure of the panel light, the panel not only protects the internal light source, but also affects the overall astigmatism effect of the panel light. Currently, the panel is often fixed to the lamp body by snap-fitting. For example, Chinese patent CN202221052U discloses a lamp panel fixing structure, including a light box and a panel, one side of the panel is hinged to the frame of the light box, and the other side opposite to the hinged side is connected to the frame by snap-fitting. However, this panel fixing method is relatively cumbersome and inconvenient to assemble and disassemble. Moreover, during long-term use, the snap-fit ​​structure is easily loosened due to the influence of environmental vibrations and temperature changes, resulting in poor panel stability, affecting the astigmatism effect, and also weakening its protective effect on the internal light source.
