2. A modeling projection lamp comprising:
a stand comprising:
a stationary bracket;
a first swing bracket connected to the stationary bracket and capable of swinging about a first axis with respect to the stationary bracket; and
a first gear securely mounted on the first swing bracket;
a driving assembly comprising:
a rotating mechanism;
a rotating arm comprising:
a first end rotatably connected to the rotating mechanism; and
a second end opposite the first end; and
a second swing bracket rotatably connected to the second end of the rotating arm and connected to the first swing bracket, the second swing bracket capable of swinging about a second axis with respect to the first swing bracket, the second axis being non-parallel with the first axis;
an illumination assembly securely mounted on the second swing bracket;
a lens assembly securely mounted on the second swing bracket;
a first pattern frame securely mounted on the second swing bracket and located between the illumination assembly and the lens assembly; and
a second pattern frame movably connected to the second swing bracket and located between the illumination assembly and the lens assembly; the second pattern frame comprising:
a plurality of tooth portions, the tooth portions connected to the first gear;
wherein when the rotating arm is rotated, the first swing bracket is driven to swing about the first axis with respect to the stationary bracket, and the second swing bracket is driven to swing about the second axis with respect to the first swing bracket at the same time, so that when the second swing bracket swings with respect to the first swing bracket, the first gear is capable of driving the tooth portions, thereby driving the second pattern frame to reciprocate or rotate with respect to the first pattern frame.
