[0027] In an optional embodiment, an annular groove 331 is formed on the inner side of the raised protection ring 33 , and the sealing ring 34 is filled into the annular groove 331 .
[0028] It should be noted that an annular groove 331 is provided on the inner side of the raised protection ring 33 , and the sealing ring 34 is filled into the annular groove 331 , which further enhances the sealing and waterproof performance of the lens assembly 3 .

The substrate 321 is the basis of the lens and provides basic optical performance; the transition layer 322 optimizes the refractive index of light when it passes through, reduces reflection loss, and improves light transmittance; the anti-reflection layer 323 further enhances the penetration ability of light and ensures high light efficiency. The hydrophobic nano coating on the surface of the lens assembly 3 can quickly repel water droplets, prevent water droplets from forming on the lens surface, reduce light scattering and absorption, and further enhance the light efficiency of the lens. The sealing ring 34 filled between the raised protective ring 33 and the multi-layer coated lens 32, and the waterproof ring 35 at the contact gap between the raised protective ring 33 and the mounting frame 31, together constitute a waterproof barrier for the lens. The sealing ring 34 is filled in the annular groove 331 of the raised protective ring 33 to form a tight seal to prevent moisture from penetrating from the internal structure of the lens assembly 3; the waterproof ring 35 prevents moisture from entering through the gap of the external structure.
