The cover has an annular cover body (3) with C-shaped cross-sections in radial directions, an inner wall surface (11), and an outer wall surface (10). A lighting unit (4) is mounted on the outer wall surface of the cover body and includes a lamp (41). A control circuit module (42) is coupled to the lamp, such that the lighting unit generates light that radiates from the outer wall surface of the cover body.
