In addition, a handle hole is provided on the dust plug 900, making it easy to open the dust plug 900.

[0053] As shown in Figures 1, 5 and 8, in order to improve the stability of the base unit 100, in this embodiment, the lighting device further includes a slide member 1000, several support stands 1100, a support rod 1200, and a support fixed cover 1300, wherein the slide member 1000 is fitted into the rail member 140 so as to slide, and each support stand 1100 has a rotating end 1110, which is rotatably connected to the slide member 1000, such that the support stand 1100 can rotate toward or away from the slide member 1000 around the rotating end 1110 as a rotation axis, and the support rod 1200 has a first connecting end 1210 and a second connecting end 1220 arranged opposite to each other, wherein the first connecting end 1210 is rotatably connected to the middle part of the support stand 1100 by the support fixed cover 1300, and the second connecting end 1220 is rotatably connected to the base 120.

[0054] That is, the slide member 1000 can slide freely on the rail member 140, and when the slide member 1000 moves to the bottom and contacts the base 120, it is simultaneously restricted by the base 120 and does not slide off the rail member 140. The support stand 1100 and the slide member 1000 are connected and fixed by a rotating end 1110, the support stand 1100 moves by rotating about the rotating end 1110 as a rotation axis, and a support rod 1200 is provided between the support stand 1100 and the base 120, one end of the support rod 1200 approaching the support stand 1100 is a first connecting end 1210, and one end of the support rod 1200 approaching the base 120 is a second connecting end 1210.

[0055] When the sliding member 1000 is pressed by a force and moves toward the base 120, the distance between the pivot end 1110 and the second connecting end 1220 becomes shorter, and the downward pressure from the sliding member 1000 and the upward supporting force from the base 120 generate a resultant force toward the first connecting end 1210. In this case, the support stand 1100 is opened outward due to the action of the resultant force, i.e., the support stand 1100 is in an open state, and the radius of the ground support point is increased, thereby effectively improving the stability of the lighting device when it is standing, and the lighting device can stand stably even in a tilted situation.

[0056] Correspondingly, when the sliding member 1000 is subjected to an upward pulling force, the acting force is reversed, and the supporting stand 1100 is retracted inward by the acting force, so that the supporting stand 1100 can be opened and retracted by moving the sliding member 1000. In the retracted state, the volume is smaller and it is convenient to carry.
