[0036] In some embodiments, the light source box is configured to project light as a whole. In a preferred embodiment of the present application, the bottom of the light source box is configured to be light-permeable. In other embodiments, the bottom of the light source box and the sidewalls of the light source box are both configured to be light-permeable. This application does not limit this.

[0037] The following is combined with the appendix of this manual Figures 1 to 4 , the preferred implementation modes of the present disclosure are further elaborated in detail.

[0038] According to some embodiments, Figure 1 , Figure 2 , Figure 4 As shown, the light source box includes a light-transmitting plate 3 and a lamp trough 4. The light source plate is installed inside the lamp trough 4. The light-transmitting plate 3 is sealedly connected to the notch of the lamp trough 4. The bottom of the lamp trough 4 is connected to the bottom of the power box through the second inlet pipe 2.

[0039] The notch of the lamp slot 4 is oriented vertically downward, and when the light source panel emits light, it illuminates downward through the light-transmitting panel 3 .

[0040] According to some embodiments, Figure 1 , Figure 2 , Figure 4 As shown, the light source box also includes a pressing plate 5, a mounting groove 6 is opened at the notch of the lamp groove 4, a first limiting block 7 is connected to the edge of the mounting groove 6, the light-transmitting plate 3 is arranged in the mounting groove 6, screw holes are opened on the outer side of the pressing plate 5 and the first limiting block 7, the outer side of the pressing plate 5 is connected to the first limiting block 7 by screws, and the inner side of the pressing plate 5 is used to press the edge of the light-transmitting plate 3.

[0041] Further, such as Figure 4As shown, the inner side of the first limit block 7 is connected to the outer edge of the mounting groove 6, the outer side of the first limit block 7 is connected to the first folded edge 8, the outer end of the pressure plate 5 is connected to the second folded edge 9, the inner end of the pressure plate 5 is connected to the third folded edge 10, the second folded edge 9 is inserted into the inner side of the first folded edge 8, and the third folded edge 10 is used to press the edge of the light-transmitting plate 3.

[0042] The length of the third folded edge 10 is greater than that of the second folded edge 9 , so that when the outer side of the pressing plate 5 is connected to the first limiting block 7 by screws, the inner side of the pressing plate 5 can press the edge of the light-transmitting plate 3 .

Alternatively, an internal thread is set on the inner side of the lower end of the first connecting tube 12, and an external thread is set on the outer side of the upper end of the second connecting tube 13, and the lower end of the first connecting tube 12 is threadedly connected to the upper end of the second connecting tube 13. At this time, the diameter of the first connecting tube 12 is larger than the diameter of the second connecting tube 13. Alternatively, an external thread is provided on the outer side of the lower end of the first inlet pipe 1, and an internal thread is provided on the inner side of the upper end of the second connecting pipe 13, and the lower end of the first connecting pipe 12 is threadedly connected with the upper end of the second connecting pipe 13. At this time, the diameter of the first connecting pipe 12 is smaller than the diameter of the second connecting pipe 13.

[0051] According to some embodiments, Figure 2 , Figure 4 As shown, the power box includes an upper shell 16 and a lower shell 17. The outer edge of the lower shell 17 is bent downward to form a fourth folded edge 18, and the outer edge of the upper shell 16 is bent downward to form a fifth folded edge 19. The fourth folded edge 18 is used to embed into the inner side of the fifth folded edge 19. The upper shell 16 and the lower shell 17 are sealed and connected by the fourth folded edge 18 and the fifth folded edge 19.

[0052] Further, such as Figure 2 , Figure 4 As shown, the power box includes, in addition to the above-mentioned embodiments, the outer edge of the fifth folded edge 19 is connected to the sixth folded edge 20, the edge of the sixth folded edge 20 is connected to the inner curled edge 21, the edge of the fourth folded edge 18 is connected to the seventh folded edge 22 corresponding to the sixth folded edge 20, the sixth folded edge 20 and the seventh folded edge 22 are both provided with screw holes, and the sixth folded edge 20 and the seventh folded edge 22 are connected by screws.
