[0029] like Figures 1 to 6 As shown, a portable lighting device comprises:

[0030] Base 100;

[0031] The light-emitting assembly includes a light-emitting member 200 movably disposed on a base 100, the light-emitting member 200 includes at least two rotatably connected light-emitting sections, and each light-emitting section has a built-in light source, wherein the light-emitting member 200 can rotate relative to the base 100 to achieve primary extension or storage of the light-emitting member 200, and when one of the light-emitting sections rotates to a first angle, the two light-emitting sections are arranged in a left-right structure to achieve secondary storage of the light-emitting member 200, and when one of the light-emitting sections rotates to a second angle, the two light-emitting sections are arranged in an upper-lower structure to achieve secondary extension of the light-emitting member 200. The light-emitting member 200 can first perform primary extension relative to the base 100, and then perform secondary extension through the light-emitting sections, which not only effectively expands the irradiation range of the light-emitting member 200 when it is unfolded, but also ensures the compactness and smallness of the overall structure when the light-emitting member 200 is retracted, and effectively improves the portability of the lighting device.

[0032] like Figures 1 to 6 As shown, in this embodiment, the base 100 is triangular and is used as a supporting structure for the light-emitting component. A magnet 110 is provided on the side of the base 100 facing away from the light-emitting component, and at least one mounting hole 120 is provided on the base 100, so that the lighting device can be adsorbed on a magnetic metal through the magnet 110, and can also be fixed on a support through the mounting hole 120, which effectively enriches the fixing methods of the lighting device and thus effectively expands the applicable scenarios of the lighting device.

[0033] Preferably, in this embodiment, there are two mounting holes 120, both of which are threaded holes, wherein the two mounting holes 120 are respectively arranged on the side of the base 100 facing toward or away from the light-emitting component, and the two mounting holes 120 are respectively coaxial with the base 100; by expanding the mounting points of the base 100, the applicable scenarios of the lighting device are further expanded.

[0034] In order to realize power supply and lighting control of the light-emitting component, in the present embodiment, the base 100 also includes a accommodating cavity, in which a circuit board 500 and a power supply 400 electrically connected to the light-emitting component are provided, and the base 100 is provided with a charging interface 600, an indicator light 610, an adjustment button 700 and a switch button 710 electrically connected to the circuit board 500 respectively, wherein the charging interface 600 is a USB interface, the indicator light 610 is used to display the remaining power of the power supply 400, the adjustment button 700 is used to adjust the color temperature of the light source, and the switch button 710 is used to control the lighting and shutting down of the light source, which effectively improves the convenience of operating the lighting device and enriches the lighting color.

[0035] In the present embodiment, a receiving groove 101 for accommodating the movable part 300 is provided on the side of the base 100 facing the light-emitting component. The receiving groove 101 is L-shaped, and a first rotating hole 102 rotatably connected to the first rotating shaft 320 is provided on the side wall of the receiving groove 101, so that the light-emitting part 200 can be rotated relative to the base 100 through the movable part 300, thereby realizing the first-level extension and storage of the light-emitting part 200, so as to expand the illumination range of the light-emitting part 200 when in use and ensure the portability of the light-emitting part 200 when stored.

[0036] In this embodiment, the number of the receiving grooves 101 matches the number of the light-emitting elements 200 , and two first rotation holes 102 arranged symmetrically on the inner wall of each receiving groove 101 are provided, which effectively improves the stability of the light-emitting element 200 during rotation.

[0037] In this embodiment, the receiving groove 101 includes a first limiting surface 103 and a second limiting surface 104 , and the extension lines of the first limiting surface 103 and the second limiting surface 104 are perpendicular to each other, so as to limit the rotation angle of the light emitting element 200 .

[0038] In order to realize the lighting function of the lighting device, in this embodiment, the light-emitting component includes a light-emitting member 200 movably arranged on the base 100, and the light-emitting member 200 is provided with three groups, and the three groups of light-emitting members 200 are arranged in a ring shape; on the one hand, the compactness of the overall structure when the light-emitting member 200 is stored is ensured, and the volume of the overall structure of the lighting device in the storage state is effectively reduced; on the other hand, the ring arrangement of the three groups of light-emitting members 200 can expand the lighting range of the light-emitting member 200, avoid the local over-brightness or over-darkness caused by a single light source, and improve the overall brightness consistency of the illuminated area.

[0039] In this embodiment, the three groups of light-emitting components 200 are rotatably connected to the base 100 through movable parts 300, so that the three groups of light-emitting components 200 can be extended and stored separately. Not only can the different lighting needs of users be met, but even if one of the groups fails, the other two groups can still continue to work, thereby ensuring the basic lighting function and improving the overall reliability of the lighting device.

[0040] In this embodiment, the movable part 300 includes a movable part 310 rotatably arranged in the accommodating groove 101, and a first rotating shaft 320 arranged on the movable part 310 and rotatably connected to the first rotating hole 102. The first rotating shaft 320 is arranged horizontally, extends along its own axial direction, and passes through the movable part 310, so that the movable part 300 can drive the light-emitting part 200 to rotate relative to the base 100 around the axis of the first rotating shaft 320; when the movable part 300 rotates to a third angle, the light-emitting part 200 is vertically connected to the base 100 to form a first-level storage state of the light-emitting part 200, and when the movable part 300 rotates to a fourth angle, the light-emitting part 200 is horizontally connected to the base 100 to form a first-level extension state of the light-emitting part 200.

The fourth angle is 90°, which can effectively protect the light-emitting component 200 when not in use.

[0042] In order to achieve the adjustability of the irradiation direction of the light-emitting component 200, in the present embodiment, the movable portion 310 is further provided with a second rotating hole 311 rotatably connected to the second rotating shaft 213. The second rotating hole 311 is arranged vertically to the first rotating shaft 320 so that the light-emitting component 200 can rotate relative to the base 100 around the axis of the second rotating shaft 213, thereby achieving the adjustment of the irradiation direction of the light-emitting component 200, thereby satisfying the user's demand for freely adjusting the lighting direction according to actual needs.

[0043] In this embodiment, the inner wall of the movable part 310 is provided with a boss 312 and a groove 313 which are arranged opposite to each other, wherein the boss 312 extends along the rotation direction of the second rotating shaft 213. When the second rotating shaft 213 rotates to the fifth angle, the limiting portion 214 abuts against the boss 312 to stop the rotation of the second rotating shaft 213, thereby preventing the light-emitting component 200 from winding due to excessive rotation angle; and the setting of the groove 313 can prevent the second rotating shaft 213 from interfering with the limiting portion 214 when rotating forward or reversely, thereby allowing the light-emitting component 200 to adjust the illumination direction in both left and right directions.

[0044] Preferably, in this embodiment, the fifth angle is 30° or 190°.

[0046] In this embodiment, the first angle is 0°, that is, in the initial state, the second light-emitting section 220 is not extended, the light-emitting element 200 is in the secondary storage state, and the second angle is 180°. It should be noted that the first angle, the second angle, the third angle, the fourth angle and the fifth angle can be adjusted to any angle according to actual needs.
