Through adopting above-mentioned technical scheme, accuse light board 20 and pivot 40 can rotate for connecting seat 10 to the installation angle of adjusting accuse light board 20, and then the angle of light-emitting of adjustment lamp body. Therefore, the light shielding device 100 can not only flexibly adjust the light emitting surface of the lamp body, but also adjust the light emitting angle of the lamp body, thereby satisfying the rich light control requirement.

Since the light shielding plate 60 is connected to the rotating shaft 40, when the rotating shaft 40 and the light control panel 20 slide along the sliding hole 31, the light shielding plate 60 slides along the sliding hole 31 along with the rotating shaft 40 to change the size of the light emitting surface; meanwhile, since the light shielding plate 60 is rotatably connected to the rotating shaft 40 and the end of the light shielding plate 60 is inserted into the sliding hole 31, if the angle of the light control plate 20 needs to be adjusted, the light control plate 20 and the rotating shaft 40 can rotate relative to the connecting base 10, and the light shielding plate 60 does not rotate along with the rotating shaft 40.

Optionally, the end of the light shielding plate 60 is flush with the end of the rotating shaft 40 or protrudes from the end of the rotating shaft 40, so that the light shielding effect can be improved, and light leakage of the lamp body can be reduced.
