Then, the ventilator 11 is arranged between the ventilation shaft 7 and the light pipe, and the bottom of the light pipe is closed by the light diffusion plate 12, which can effectively prevent smoke from entering the light pipe and affecting the lighting effect. The fence 6 is preferably a fence with an outer square and an inner circle, so that the fence has a certain thickness, and the outer sidewall in the vertical direction can be used to more conveniently install the shutter. The shutter is installed on the fence, and the window gap of the shutter is used as the ventilation opening. Thus, the size of the ventilation opening can be adjusted conveniently. The ventilation shaft 7 is preferably a barrel-shaped ventilation shaft 7 in the vertical direction.

[0018] Preferably, the light cover 1 is semispherical, the opening of the light cover 1 faces downward, the edge of the light cover 1 is provided with a first flange 2 extending inward, the top of the light pipe is provided with a second flange extending outward, the top of the fence is provided with a third flange 3 extending outward, and the second flange 3 is pressed between the first flange 2 and the third flange 3. On the one hand, the structure of the light cover 1, the light pipe and the fence is optimized in the utility model, and the connection and disconnection among the three are more simple by adding the flanges. On the other hand, the normal projection area of the light cover 1 is guaranteed to be the largest among the three by limiting the position of the flange, so that the lighting effect is guaranteed, and the fence plays a role in rain protection. Preferably, the outer diameter of the third flange is smaller than the outer diameter of the first flange, and the outer diameter of the second flange is smaller than the outer diameter of the third flange. The third flange and the first flange are filled with a sealing ring 4. Thus, the sealing effect at the position is improved by using the sealing ring 4. An annular groove with an outward opening is preferably arranged on the second flange, and the sealing ring 4 is sleeved in the annular groove. Thus, the position of the sealing ring 4 is limited by the second flange, and the sealing ring 4 can move along with the movement of the light pipe.
