[0038] Working principle:

[0039] The emergency lamp comprises a polygonal main body 13, each side of which is provided with an LED lamp plate 3. The top plate 1 and the bottom plate 2 are installed at the two ends of the main body, the outer ring of the bottom plate 2 is provided with a connecting groove 5, the connecting groove is provided with a connecting column 11, the LED lamp plate 3 is sleeved with the connecting column 11 through a rectangular groove 20 on the connecting plate 6, and is fixed through a hand screw bolt 7. The friction blocks 10 at the two ends of the connecting column 11 are in frictional fit with the inner wall of the circular groove, so that the LED lamp plate 3 can rotate around the connecting column 11 and be kept at the adjusted angle.

[0040] The illumination angle of the LED lamp plate 3 can be manually adjusted and positioned through the friction force between the friction blocks 10 and the inner wall of the circular groove. Since the connecting column 11 and the groove 20 are in rectangular fit, the rotation of the lamp plate is prevented. The hand screw bolt 7 is not needed to be operated when adjusting the angle, and is only used to prevent the lamp plate from being axially detached from the connecting column.

[0041] When it is needed to expand the illumination range, the hand screw bolt 7 can be unscrewed, and the LED lamp plate 3 can be taken off from the main body. At this time, the first wire 16 in the winding assembly can be pulled out from the winding disc 15, so that the LED lamp plate 3 is away from the main body, forming an independent secondary illumination point. The slip ring 18 in the winding disc 15 ensures that the circuit is always connected during the rotating unwinding process, and the second wire 17 transmits power from the battery in the main body to the LED lamp plate.

[0042] The top plate 1 is provided with a handle 8, which facilitates carrying. All the LED lamp plates 3 can illuminate towards different angles, or can be all horizontally expanded to form a strong light flashlight mode.

[0043] After the part of the lamp plate is taken off and the wire is pulled out, the distributed lighting of the main lighting point and multiple auxiliary lighting points can be realized, which is suitable for multiple scenes such as emergency, camping, maintenance and the like.

[0044] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any change or replacement without creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
