The two positioning rings 180 and the fixing ring 170 are positioned on the same side of the heat radiation box 2, the axial lead of the positioning rings 180 is parallel to the axial lead of the fixing ring 170, the two positioning rings 180 are arranged at intervals along the length direction of the second limiting section 1602, internal threads are arranged on the inner side walls of the positioning rings 180, and the positioning rings 180 are fixedly connected with the heat radiation box 2. The screw of the connecting bolt 190 is inserted into the fixing ring 170, and when the cover plate 140 is abutted against the scraper 110 or the ventilation hole 71 is located at one side of the first side wall 21 facing the outside of the heat dissipation box 2, the screw of the connecting bolt 190 can be screwed into one of the positioning rings 180, so that the sliding plate 7 is limited to slide. When the cover plate 140 abuts against the scraper 110, the screw of the connecting bolt 190 is connected in one of the fixing rings 170, so that the cover plate 140 keeps abutting against the scraper 110; when the ventilation holes 71 are located at the side of the first side wall 21 facing the outside of the heat radiation box 2, the screw of the connection bolt 190 is connected to the inside of the other fixing ring 170, so that the ventilation holes 71 remain located at the side of the first side wall 21 facing the outside of the heat radiation box 2. After the connecting bolt 190 breaks the threaded connection with the fixing ring 170, the sliding plate 7 can be driven to slide by the first limiting section 1601, and the plug 130 can be driven to move by the second limiting section 1602.

In some embodiments, referring to fig. 2 and 3, the wall washer light further includes a drive rod 200. The driving rod 200 is perpendicular to the connecting shaft 61 and is fixedly connected with the connecting shaft 61, and when the first air outlet section 51 is slidably arranged in the air outlet hole 23 and the cover plate 140 is abutted to the scraper 110, the driving rod 200 is slidably sleeved on the first limiting section 1601. The first air outlet section 51 is kept penetrating into the air outlet hole 23 by limiting the driving rod 200 by the first limiting section 1601. When the first limiting section 1601 slides out of the driving rod 200, the first air outlet section 51 can be driven to slide out of the air outlet hole 23, and then the driving rod 200 drives the connecting shaft 61 to rotate, so that the second air outlet section 52 is aligned with the air outlet hole 23, which saves labor.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
