The dial switch 400 is arranged in the accommodating cavity 210, and is electrically connected with the circuit board 300 and the illuminating element 220.

[0034] In actual use, the illuminating element 220 is powered and controlled by the circuit board 300 to start and stop the illuminating element 220, so as to realize the illumination. When the color temperature of the illumination needs to be adjusted, the lamp body 200 is disassembled from the junction box 100, so that the dial switch 400 in the accommodating cavity 210 is exposed, and different color temperatures are switched by the dial switch 400 for use.

[0035] In the embodiment, the junction box 100 and the lamp body 200 are arranged in an up-down mode. The junction box 100 is arranged on the upper side of the lamp body 200, and the illuminating element 220 is arranged on the lower side of the lamp body 200.

[0036] The outer side of the lamp body 200 is rotationally provided with a connecting shaft 230. The junction box 100 has a hinged end 140 rotationally hinged with the connecting shaft 230. When the color temperature is switched, the dial switch 400 in the accommodating cavity 210 needs to be exposed and dialed, so the lamp body 200 needs to be disassembled from the junction box 100. In the embodiment, the lamp body 200 and the junction box 100 are rotationally hinged through the connecting shaft 230, so that the lamp body 200 can be flipped open relative to the junction box 100, facilitating the disassembly and assembly between the lamp body 200 and the junction box 100.

[0037] In the embodiment, the lamp body 200 and the junction box 100 are connected through screw locking. The upper end edge of the lamp body 200 is distributed with a plurality of connecting holes, and the connecting holes are provided with connecting screws for locking and fixing the lamp body 200 and the junction box 100. In order to facilitate disassembly, the head of the connecting screw is arranged at the lower end. The junction box 100 has a connecting screw hole corresponding to the connecting screw. The connecting screw passes through the connecting hole and is threadedly connected with the connecting screw hole.

[0038] In order to enhance the sealing performance between the lamp body 200 and the junction box 100, the upper end of the lamp body 200 has a convex edge 211 which is upwardly convex. The lower end of the junction box 100 has a groove 110 corresponding to the convex edge 211. When the connecting screw locks and connects the lamp body 200 and the junction box 100, the convex edge 211 is embedded in the groove 110.

[0039] In the embodiment, the upper end of the lamp body 200 is consistent with the shape of the lower end of the junction box 100, the convex edge 211 extends along the upper end edge of the lamp body 200, and the groove 110 extends along the lower end edge of the junction box 100. The convex edge 211 and the groove 110 both extend along a closed loop path. To adapt to the lighting use in a water environment, the groove 110 is embedded with a sealing ring 120.
