Wherein the first surface 23 of the light bar 20 faces radially outward when the tail end 22 of the light bar 20 is in the first position. When the tail end 22 of the light bar 20 is located at the second position, the light bar 20 is open relative to the main body 10, and the first surface 23 of the light bar 20 faces the second end 12 of the main body 10. Specifically, in the first position, the extending direction of the light bar 20 is perpendicular to the axial end surface 111 of the main body 10, as shown in fig. 1. In the second position, the extending direction of the light bars 20 is parallel to the axial end surface 111, and the tail ends 22 of the light bars 20 are far away from each other, as shown in fig. 2. And each light bar 20 can rotate around the corresponding edge 1111 of the axial end surface 111 toward the direction close to the second end 12 to the second position when in the first position. Conversely, in the second position, each light bar 20 can rotate around the corresponding edge 1111 of the axial end surface 111 to the first position in a direction away from the second end 12. Wherein, every light bar 20 all can be in primary importance or second place, and the user can switch each light bar 20's position according to self user demand to obtain the lighting device 100 of multiple molding, realize different irradiation methods, with the application scene of adaptation difference, it is very convenient.

In this embodiment, the light bars 20 have the same size and shape, and are substantially isosceles trapezoid cylinders. The first surface 23 and the second surface 24 are parallel to the extending direction of the light bar 20. In other alternative embodiments, the dimensions of the light bars 20 may be different or not identical, such as having different thicknesses or lengths. The edges of light bar 20 can be of a streamlined design.

Preferably, the length of the bottom edge 231 of light bar 20 (i.e., the bottom edge 231 of the isosceles trapezoid shown in fig. 5) is no greater than the length of the edge 1111 of axial end surface 111. More preferably, lower base 231 has a length equal to the length of edge 1111 of axial end surface 111. When the light bar 20 is in the first position, the lower edge 231 is flush with the edge 1111 of the axial end surface 111, so that the overall appearance of the lighting device 100 is more consistent when the light bar 20 is in the second position. In other embodiments, when the axial end surface 111 is not a regular polygon, it is preferable that the length of the lower bottom edge 231 of each light bar 20 is equal to the length of the edge 1111 of the corresponding axial end surface 111. Such that bottom edge 231 is also flush with edge 1111 of axial end surface 111 when light bar 20 is in the first position.

As shown in fig. 1 and 5, each light bar 20 further has an opposite inclined surface 25. The included angle α between the two inclined surfaces 25 of the light bar 20 of the present embodiment is 90 °. When 4 light bars all are in the first position, adjacent light bar 20 is with two liang laminating of inclined plane 25 for 4 light bars can enclose the lamp pole of synthetic cuboid, and the light emitting area of each light bar is radially outwards along the lamp pole. It is understood that when the axial end surface 111 is a regular n-sided polygon, the inclined surfaces of the light emitting lamps 20 preferably form an angle of 360/n (n is an integer of 3 or more). When the n light bars 20 are attached to each other by the inclined surfaces 25, the end surfaces of the head ends 21 and the tail ends 22 of the n light bars can be respectively enclosed to form a complete ring surface, and the n light bars 20 can also be enclosed to form a lamp post. The overall shape of the lighting device 100 in the folded state is more coordinated and the placement is stable.

And preferably, the lighting device 100 has an overall axial length of 20cm to 30cm when stowed. In the case of sufficient space or a need for divergent light, the user can rotate the light bar 20 to the second position, so that the lighting device 100 can function as a ceiling lamp or wall lamp. When the space is not large enough or concentrated illumination is needed, the lighting device 100 can be folded to make the light bars 20 surround and emit light, so as to enhance the illumination intensity. Due to the size of the main body portion 10 suitable for holding, the lighting device 100 can now function as a portable lamp, thereby enabling applications in different scenes. Preferably, a strong magnet is also built into the second end 12 of the body portion 10 to achieve an inverted magnetic attraction.

As shown in fig. 4, the light bars 20 are rotatably connected to the slots 112 through the rotating shafts 30. The rotating shaft 30 is convexly disposed at the head end 21 of the light bar 20. The shaft 30 can be engaged with the opposite side walls of the slot 112. Since the slot 112 forms a rectangular opening at the axial end surface 111 and the outer periphery of the main body 10, the rotation of the shaft 30 at the slot 112 is always perpendicular to the edge 1111 of the axial end surface 111, so that the rotation angle between the axial end surface 111 and the outer periphery of the main body 10 is 90 °. By rotating the rotating shaft 30 in the slot 112, the light bar 20 can rotate between the first position and the second position around the rotating shaft perpendicular to the longitudinal direction of the main body 10. In other embodiments, other connection manners may be selected as long as the light bar 20 can rotate around the corresponding edge 111 of the axial end surface 111 to the first position and the second position relative to the main body 10.
