The utility model relates to the technical field of LED (light-emitting diode) project lamps, in particular to a wall-mounted combined LED project lamp, which comprises a lamp body, a fixing plate and a lamp cover, a positioning structure is mounted on the back face of the lamp body and comprises a connecting plate, the connecting plate is fixedly mounted at the rear end of the fixing plate through bolts, a lamp holder is mounted on the rear side of the connecting plate, a mounting groove is formed in the surface of the middle of the lamp holder, and an inserting groove is formed in the front end of the lamp holder. Due to the fact that the connecting plate is arranged on the front side of the lamp holder, after the lamp holder is installed on the wall through expansion bolts, the lamp body can be lifted, the connecting plate is inserted into the inserting groove, the bolt assembly is screwed on, the connecting plate and the lamp holder are connected and fixed, installation is convenient and fast, when the lamp body is replaced, the bolt assembly can be screwed off to separate the connecting plate from the lamp holder, and replacement is convenient. The lamp holder does not need to be taken down and replaced, the connecting strength of the expansion bolt and the wall can be guaranteed, and the installation stability of the device is improved.

The utility model relates to the technical field of lamps, and discloses an angle-rotatable wall lamp which comprises a rotating bottom column, the front end of the rotating bottom column is rotatably connected with a rotating disc, the front end of the rotating disc is fixedly connected with an inner rotating block, the inner rotating block is internally connected with a rotating block in a sliding mode, the outer portion of the rotating block is connected with a lamp shell in a sliding mode, and the lamp shell is fixedly connected with the rotating disc. A clamping groove block is fixedly connected to the interior of the lamp shell, a clamping rod is slidably connected to the top of the clamping groove block, a large rotating column is rotatably connected to the interior of the clamping rod, a limiting block is rotatably connected to the outer end of the large rotating column, and a transparent lampshade is fixedly connected to the bottom of the limiting block. According to the utility model, the clamping rod is firmly fastened, so that not only is the installation stable and not easy to loosen, but also the internal part of the lampshade can be kept clean at any time through the convenient disassembly and assembly mode, the illumination effect is prevented from being influenced by the shading of light rays by dirt, the loss of the lamp caused by frequent disassembly is reduced, and the overall service life is prolonged.
