[0032] Working principle and use process of the utility model: After the utility model is installed, firstly, two sets of mounting plates 23 are mounted inside the box body 1, and then the lighting lamp 26 is mounted on the surface of the mounting plate 23, and then the lampshade 25 is detachably mounted on the surface of the lighting lamp 26, and then the advertisement to be displayed is placed on the surface of the light board 2 for installation, so that the lighting lamp 26 can illuminate it, and the lampshade 25 can be protected, and at the same time, it can prevent the light source from being too strong to affect the comfort of pedestrians watching the advertisement;

[0033] Before lighting the advertisement, first set the movement time of the timing motor 4. After the lighting lamp 26 has been used for a certain period of time, the timing motor 4 is powered on and rotates to drive the rotating shaft 5 to rotate. The rotating shaft 5 drives the first bevel gear 6 to rotate. When the first bevel gear 6 rotates, it can drive the two sets of second bevel gears 7 to rotate. The rotation of the second bevel gear 7 can drive the turntable 8 to rotate. When the turntable 8 rotates, it can drive the lever 9 to slide inside the sliding frame 10, thereby pushing the sliding frame 10 to reciprocate left and right.

[0034] When the sliding frame 10 reciprocates left and right, it can drive the wave plate 13 to move. The movement of the wave plate 13 can intermittently push the piston rod 14 to slide inside the piston cylinder 15, and the dust, insects, etc. swept by the brush 24 can be sucked into the interior of the piston cylinder 15 through the multiple groups of suction ports set on the surface of the exhaust pipe 16, and then transported from the interior of the piston cylinder 15 to the interior of the storage bag 17 for collection. The staff only needs to replace and clean the storage bag 17 regularly, which can effectively reduce the work intensity of the staff, improve the heat dissipation efficiency of the lighting device, and improve the quality of advertising lighting;

[0035] When the rotating shaft 5 rotates, it can drive the push plate 18 to rotate. The rotation of the push plate 18 intermittently pushes the sliding column 19 to move left and right. The movement of the sliding column 19 can push the swing frame 20 to intermittently rotate around the pin shaft inside the bracket 22, thereby driving the vibrating ball 21 to knock on the inner side of the ventilation net 3, which can shake off dust, insects, etc., and make the piston cylinder 15 collect them into the storage bag 17, which can further improve the protection of the lighting lamp 26, facilitate its heat dissipation work for the advertisement installed on the surface of the light board 2, increase its service life, and reduce the cost of use.
