2. The lamp cover of claim 1, wherein: the lampshade further comprises a concave-convex surface, the concave-convex surface is arranged on the surface, away from the luminous body, of the lampshade body, and the concave-convex surface refracts light rays emitted by the luminous body.

3. The lamp cover of claim 2, wherein: the concave-convex surface comprises a plurality of convex blocks distributed in an array mode, and the convex blocks are formed by protruding towards one side far away from the luminous body on the surface of the lampshade body.

4. A lampshade as defined in claim 3, characterized in that: the height of the projection relative to the surface of the lampshade body is 0.7-1.1 mm.

5. A lampshade as defined in claim 3, characterized in that: the center distance between the adjacent lugs is 3-5mm, each lug comprises a conical bottom and a circular top, and the diameter of each circular top is 1.1-1.5 mm.

6. The lamp cover of claim 2, wherein: the lampshade body comprises a straight plate and two side plates, the two side plates are arranged on two opposite sides of the straight plate, the straight plate and the side plates are integrally formed, a cavity is formed between the side plates and the straight plate, the luminous body is arranged in the cavity, and the concave-convex surface is arranged on the surface of the straight plate far away from the luminous body.

7. The mask of claim 6, wherein: the thickness of the straight plate is 1.7-1.95 mm.

8. The mask of claim 6, wherein: the two side plates are provided with corrugated surfaces on one surfaces facing the light-emitting bodies, and the corrugated surfaces enable part of light rays emitted by the light-emitting bodies to be uniformly reflected to the straight plates.

9. The mask of claim 8, wherein: the corrugated surface comprises a plurality of first inclined surfaces and second inclined surfaces which are uniformly arranged, the first inclined surfaces and the second inclined surfaces are arranged adjacently, the first inclined surfaces are connected with the second inclined surfaces through arc surfaces, the area of the first inclined surfaces is larger than that of the second inclined surfaces, the distance from the first inclined surfaces to the outer wall of the side plate is gradually increased from the positions close to the straight plate to the positions far away from the straight plate, the maximum distance is 2.35-2.45mm, and the minimum distance is 2.15-2.25 mm.

10. The mask of any of claims 1-9, wherein: the diffusion film can be made of any one of PET material, PC material or PMMA material.
