[0002] The existing projection atmosphere lamp has a lens barrel, and the LED light source is installed at one end of the lens barrel, and the film is placed in the lens barrel. The light emitted by the LED light source passes through the film and then through the lens to reach a preset point, and the pattern on the film is projected onto the point, so that a preset pattern can be formed on the projection surface outside the projection lamp. Then, the pattern projected in this way is a static pattern. If a dynamic pattern is required, a rotating mechanism is required to drive the bracket loaded with multiple films to rotate, so that the film is rotated, or multiple static imaging systems are used, and the circuit control is turned on and off in sequence to achieve a dynamic effect.
