The light source board includes a first light source 21, a second light source 22, and a control circuit board 23. In this embodiment, the lampshade panel is a UV acrylic lampshade panel. A sealing layer is provided at the connection between the lampshade panel and the lightbox body. It can be combined to form an independent sealed space, ensuring the stability of the internal structure during use. The control circuit board uses a conventional structure from existing technologies, simply applied. The first light source is a tri-color light panel, RGB light strip, or side-emitting light strip; the second light source is a tri-color light panel, RGB light strip, or side-emitting light strip. In practical applications, it can also be combined with light strips or front-emitting light strips to meet different assembly requirements and expand its applicability.

[0030] In this embodiment, at least one raised step 4 is provided on the bottom wall of the inner cavity of the light box, and a light-shielding groove 5 is provided on the top surface of the raised step. The height of the light-shielding groove can be processed and set as needed, mainly to reduce the influence of ambient light on the light inside the light-shielding groove. The raised step is fixed by snap-fit, screw, or adhesive, so the position of the raised step can be interchanged or rearranged as needed during assembly. During assembly, the position of the raised step matches the position of the lighting pattern. The first light source is fixed on the bottom wall of the inner cavity of the light box, and the second light source is fixed in the light-shielding groove. The control circuit board is connected to the first and second light sources and is used for the start and stop control of the first light source, and also for the dynamic control of the second light source. The second light source can achieve dynamic lighting effects through the control circuit board to meet local dynamic lighting needs.

[0031] In this embodiment, the lighting pattern is a human head, and the second light source is located at the eyes of the human head and matches the flow path of the tears. The second light source can present a dynamic effect of tears. In practical applications, the lighting pattern can also be other shapes, and the second light source is located in the dynamic lighting position of the lighting pattern to achieve a local dynamic lighting effect.
