Abstract The fog on the inner surface of automotive lights not only affects the optical performance of the lights and the range of driver's sight, but also reduces the driving safety. In this paper, the anti-fogging performance of transparent conductive nano-silver coating applied on automotive lights was studied through simulation analysis and test verification. Based on the transparent and conductive properties of nano-silver coating, the relationship between coating area, current, voltage and heating performance was studied. The finite element model of automotive light including nano-sliver coating lens was constructed，the fogging and defogging simulation methods on automotive light including nano-sliver coating lens was set up. And this paper investigated the influence of the fogging and defogging process of the nano-silver coating by the above simulation method, which was applied to Y19 headlamp to verify the actual application effect. The results show that the simulation results are in good agreement with the actual test results, which further verified the feasibility of the coating. The coating has good anti-fog and defogging performance, nano-silver coating is feasible to prevent the generation of fog, and after the generation of fog, nano-silver coating will greatly reduce the dissipation time of fog.
