The deformation or offset of warning signs will reduce passengers' recognition of safety information, and the warning function of the projection lamp cannot be fully utilized, causing potential safety hazards.

At the same time, the precisely positioned lamp bead assembly 562 ensures that the angle and intensity of light entering the lens group are optimal, providing a high-quality light source for the projection lens mechanism 55, ensuring the clarity and stability of the projected image, and enhancing the overall reliability and projection effect of the system; The circuit assembly 561 is electrically connected to an external power source.
