Example 1

Application method of first projection module

In use, the utility model is mounted in a designated position by the bracket and then activated. The laser emitted from the first laser source (monochromatic source or polychromatic source) sequentially passes through the color disc (monochromatic disc or polychromatic disc), the light collecting cup and the lens, reaches the reflecting mirror of the reflecting assembly, and finally is projected outwards from the first projection area on the surface cover to a required area through reflection of the reflecting mirror.

Example 2

Use method of second projection module

In use, the utility model is mounted in a designated position by the bracket and then activated. The laser of the second laser source (single-color source or multi-color source) is emitted, and then passes through the condenser and the spherical lens in sequence and is projected outwards from the second projection area (quasi-hemispherical bulge) on the surface cover to the required area.
