[0042] The shading mechanism 4 is correspondingly arranged at the opening, and the shading mechanism 4 divides the opening into a first area and a second area, and the shading mechanism 4 is used to control the transparency of the first area and the second area;

[0043] The guide component 3 is arranged corresponding to the second area, and defines the direction of light propagation through the second area, and the direction of light propagation defined by the guide component 3 is inclined relative to the direction of light propagation through the first area.

[0044] In the present technical solution, the light source 1 is a point light source or a line light source. The outer cover 2 is usually fixed on the top surface of the room, the bottom surface of the outer cover 2 is set as an opening as a whole, the light source 1 is fixed in the outer cover 2, and the outer cover 2 is set as an opaque or translucent state as a whole, reducing the degree of light diffusion through the top surface, front and back, left and right sides, and improving the effect of directional output light. The shading mechanism 4 is fixed in the outer cover 2, and the shading mechanism 4 blocks the opening, so that the outer cover 2 and the shading mechanism 4 at this time seal the space inside the outer cover 2, the shading mechanism 4 is horizontally arranged front and back, and divides the opening of the outer cover 2 into a left area and a right area, the first area is the right area, and the second area is the left area.
