Energy-saving antifouling lamp trough structure

The utility model relates to an energy-saving antifouling lamp trough structure, which belongs to the technical field of indoor lamp trough structures and is characterized by comprising a ceiling mounted at the indoor top. The extension plate is annularly arranged on the indoor inner wall and forms a preset space with the ceiling; the support plate is obliquely mounted on the extension plate; wherein the lamp strip and the lampshade are installed on the supporting plate. The hollow baffle is detachably mounted on one side, far away from the lamp strip, of the bearing surface of the extension plate; the movable plate is movably inserted into the baffle in a penetrating manner in the vertical direction; and the limiting assembly is arranged on the baffle and used for limiting the position ofthe movable plate. When the lamp groove structure is used, dust and impurities can be blocked, the influence of the dust and the impurities on the lampshade is reduced, and therefore the subsequent process of manually disass
