The invention relates to the field of LED wall lamps, in particular to a multi-angle LED wall lamp, which comprises a wall lamp body, a connecting mechanism, a mounting mechanism, a supporting mechanism, a fixing mechanism, sliding mechanisms, limiting mechanisms and limiting blocks; the mounting mechanism comprises a wall lamp, a supporting mechanism and a sliding mechanism, wherein the sliding mechanisms are arranged at two ends of the mounting mechanism and are slidingly connected in the supporting mechanism. When the multi-angle LED wall lamp is mounted, the supporting mechanism is fixed on the wall top, the fixing mechanism in the supporting mechanism is enabled to slide so as to increase the distance in the supporting mechanism, the sliding mechanism at one end of the mounting mechanism is pulled to slide into the supporting mechanism for initially fixing the mounting mechanism, the mounting mechanism is released, then the fixing mechanism is enabled to slide again to enable theother end of the supporting mechanism to move, and the sliding mechanism at the other end of the mounting mechanism is enabled to slide into the other end of the supporting mechanism, so that the mounting mechanism is fixed inside the supporting mechanism, and then the wall lamp is in threaded connection to the bottom surface of the mounting mechanism. During mounting, people do not need to pull the mounting mechanism for a long time, so that the labor intensity of people is reduced.
