[0002] The time it takes for headlight fog to dissipate is an important indicator for testing the quality of headlights. The time it takes for fog to dissipate has changed from being allowed before (half an hour to an hour is considered qualified) to not allowing fog now. The experimental standards and requirements for fogging of headlights are gradually improving, which brings new challenges to anti-fog of headlights.

[0003] At present, one of the anti-fog measures for headlights is to deploy a breathable film or a breathable screen in the cold zone of the headlight. This measure can increase the flow of gas in the cold zone of the headlight, balance the temperature distribution in the headlight, avoid the phenomenon of too low temperature in the cold zone and dead zone of gas flow, and thus reduce the risk of fogging of taillights. However, the direction of the external airflow entering the lamp housing and the direction of the airflow in the lamp housing after entering are relatively fixed. The gas flow route cannot be effectively changed according to the environment inside and outside the lamp, and the temperature distribution inside the lamp cannot be quickly and effectively balanced. The anti-fog performance is poor and the fog dissipation time is long.

[0004] In order to solve the problem that the direction of external airflow entering the lamp housing and the direction of the airflow in the lamp housing after entering cannot be effectively changed according to the environment inside and outside the lamp, resulting in poor anti-fog performance, an anti-fog car lamp based on intake airflow transformation and an airflow transformation control system are proposed.
