  "textContent": "The present application discloses a rear cover of a vehicle lamp having a valve structure and infrared radiation drying and air discharging function, which includes an end cover provided with a plurality of air vents, a connecting base for connecting with a vehicle lamp housing, and a membrane module for infrared radiation drying and air discharging. The end cover and the connecting base are assembled and connected to form the rear cover of the vehicle lamp. The membrane module is built in a cavity of the rear cover of the vehicle lamp. At least one valve is provided on a path of air circulation inside and outside the vehicle lamp housing through the rear cover of the vehicle lamp, and the at least one valve automatically opens and closes under impulse of air pressure difference. By means of the above, the present disclosure can ensure that there is no fogging and condensation in the housings of vehicle lamps and electrical and electronic equipment, so that electrical performance will not be affected by humid air environment, and the surfaces of mirrors and smooth electronic components in the housings of electrical and electronic equipment of a vehicle will not become foggy, and the performance of the electrical and electronic equipment of the vehicle can be brought into play. This can also block the entry of dust such that the electrical and electronic equipment in a vehicle is pollution-free and at a dust-tight level.",
