A modeling projection lamp has a stand, a driving assembly, a first pattern frame, and a second pattern frame. The stand has a first swing bracket and a first gear. The first gear is mounted on the first swing bracket. The driving assembly has a rotating mechanism and a second swing bracket. The rotating mechanism can drive the second swing bracket so that the first swing bracket is swung about a first axis and the second swing bracket is swung about a second axis at the same time. The second pattern frame is movably connected to the second swing bracket. With the second swing bracket swinging with respect to the first swing bracket, the second pattern frame can moves or rotates with respect to the first pattern frame. Therefore, the image formed via the first pattern and the second pattern can be a dynamic image.
