In order to increase the aesthetic property of the appearance design of the automobile, various lens modules with different sizes and novel decorative frames are applied to different automobile types. The lens module has the advantages of obvious far and near light bright cut-off line, uniform brightness, strong penetrating power, small light loss and the like, but simultaneously brings the problem of ablation of a decorative frame around the lens due to the focusing effect of the lens under the working condition of sunlight irradiation of the car lamp. Sunlight irradiated to the ground surface can be approximately parallel light under the refraction and reflection effects of the atmosphere. The parallel light is refracted-reflected-refracted when striking the lens, forming a converging light ray. When a certain specific irradiation angle is reached, the converged light rays can irradiate on the surface of the plastic decorative frame to form a focus, and an ablation phenomenon occurs.

The irradiation angle of the simulated light source has a great influence on the radiation intensity of the converged light rays irradiated on the decorative frame, and when the irradiation angle is slightly changed, the radiation intensity of a focus on the decorative frame is greatly changed; when a specific irradiation angle is found, the method cannot confirm the relative angle between the lamp and the irradiation light, and accurate adjustment is difficult.
