Projection structure, projection method, and corresponding vehicle lamp and vehicle

Method for controlling projection using a projection structure comprising a first support, a lens assembly, a film portion, a light source, a motor, a control portion, and a second support, wherein said light source, said film portion, and said lens assembly form a projection light path, said film portion being driven by said motor to rotate;

• said lens assembly comprises at least one lens, and said at least one lens is accommodated in said first support, said control portion being configured to control said motor and/or said light source;
• said second support is configured to support said first support, wherein said first support and second support respectively form a first space and a second space for accommodating said film portion said method comprising:
• controlling, by said control portion, said motor and said light source such that said motor is in a stop state when said light source emits a light beam;
• controlling the number of rotations of said motor within one cycle, the number of steps per rotation, and the time interval between two rotations;
• and
• keeping said light source lit within said time interval and turning off said light source before said motor rotates.
