[0006] Furthermore, the slotted upper end cover is provided with a shading strip, and the shading strip is arranged on the lower end surface of the panel.

[0007] Furthermore, an adhesive layer is provided on the upper end surface of the side panel, and the side panel is bonded and connected to the panel through the adhesive layer.

[0008] Furthermore, the outer side wall of the side panel is provided with a card slot, and the lower end surface of the panel is provided with a card strip adapted to the card slot.

[0009] Furthermore, the bottom shell and the light guide plate are integrally formed.

[0010] Furthermore, the side panel is provided with a wire outlet.

[0011] Furthermore, the thickness of the light guide plate is matched with the height of the side plate.

[0012] Furthermore, the thickness of the light guide plate is 3 mm to 5 mm.

[0013] Furthermore, the bottom shell is a PVC board, and the thickness of the bottom board is 1 mm to 2 mm.

[0014] Furthermore, the panel is an acrylic panel, and the thickness of the panel is 2 mm to 3 mm.

[0015] Compared with the prior art, the utility model arranges the LED light strip between the side panel and the light guide plate, and the light box can be assembled by covering the panel. It has a simple structure, a thin box body and a low manufacturing cost. Since no profile edging is required, the bottom shell, the light guide plate and the panel can be cut according to the outer contours of different shapes, which is suitable for light boxes of different shapes.
