Abstract: A projection lamp includes a light source, a spotlight assembly, a film projection assembly, a lens, and a motor. The spotlight assembly is disposed in a light emitting direction of the light source, and the spotlight assembly includes condensing lenses directly facing the light source. The film projection assembly is disposed on one side, distal from the light source, of the spotlight assembly. The lens is disposed on one side, distal from the light source, of the film projection assembly. The lens includes a plurality of lens structures, and each of the plurality of lens structures includes a first surface facing the film projection assembly. The first surface is an arc surface protruding towards the film projection assembly. An output shaft of the motor is penetrated through the spotlight assembly and the film projection assembly. The output shaft of the motor is fixedly connected to the lens.
