AI Technical Summary
Existing fog light cover structures tend to accumulate fog in environments with high humidity or large temperature variations, affecting transparency and lighting performance. At the same time, dust and impurities can easily enter, leading to component wear and a shortened lifespan.
It adopts an outer transparent cover, an inner light diffusion layer and an anti-fog layer design, combined with air inlet, air outlet and one-way ventilation mechanism, and uses the principle of thermal expansion and contraction and heating element to achieve air filtration, natural convection and fog dissipation, and prevent fog accumulation and impurities from entering.
It effectively prevents fog buildup, extends the lifespan of fog lights, ensures good transparency and lighting effects, and improves vehicle driving safety.
