The LED project lamp easy and convenient to assemble and good in heat dissipation effect comprises a cylindrical lamp shell, an installation cavity with an opening in the top is formed in the lamp shell, a light source plate and a driving power source electrically connected with the light source plate are installed in the installation cavity, the driving power source is a waterproof power source, a plurality of lamp beads are arranged on the light source plate, lenses are installed on the lamp beads, and the lenses are connected with the light source plate. The light source plate and the light shielding plate with the light transmitting hole are installed in the lamp shell, meanwhile, the heat dissipation through groove formed by the concave heat dissipation plate is formed in the outer side of the lamp shell, and the heat dissipation through groove is matched with the breathing hole in the bottom of the lamp shell to form air convection. Heat in the lamp body can be effectively dissipated, and the heat dissi
