The controller 4 is connected with the sensor component 2 and the blowing component 3, so as to control the rotation of the blowing component 3 according to the sensing data collected by the sensor component 2, make the airflow blown by the blowing component 3 enter the lamp component 1 through the air inlet, enter the fog-proof mode, or make the airflow blown by the blowing component 3 blow to the lamp component 1 outside the air inlet, enter the wind resistance reduction mode, effectively prevent the lamp component 1 from fogging, or effectively reduce the wind resistance of the lamp component 1, save energy.

[0064] The lamp assembly in the embodiment has two functional modes of fog-proof mode and wind resistance reduction mode. By increasing the sensor system for monitoring the condensation conditions of water vapor, the efficiency is improved, the intelligence is improved, the fog-proof effect is better, and the service life of the lamp component 1 is improved. The lamp assembly has two functional modes of fog-proof and wind resistance reduction. When in the fog-proof mode, the driving safety of the vehicle in foggy, snowy and rainy weather and at night can be improved, and when in the wind resistance reduction mode, the wind resistance during high-speed driving can be reduced, and the energy consumption can be reduced.

[0065] Anti-fog mode: two first temperature sensors 21, two second temperature sensors 22 and two humidity sensors 23, three kinds of sensors monitor the values at all times, and the monitoring data is transmitted to the controller 4; in order to improve the control accuracy, the controller 4 will automatically calculate the average temperature of the two first temperature sensors 21 as the temperature of the lamp shell 11; the controller 4 will automatically calculate the average humidity of the two humidity sensors 23 as the humidity of the lamp inner cavity; the controller 4 will automatically calculate the average temperature of the two second temperature sensors 22 as the temperature of the lamp inner cavity; when the lamp inner cavity is in a certain humidity and temperature condition, once the temperature of the lamp shell 11 is lower than the dew point temperature, the water vapor begins to liquefy into small water droplets and condense on the lamp shell. The controller 4 sends a control signal to start the anti-fog mode. First, open the gas flow channel, the air blowing panel 33 carries the air jet pipe 32 to blow to the lamp inner cavity, refer to Figure 3 , specifically turn the air inlet door plate 5 to the open state, and unfold the two folding pieces 7. At this time, the air blowing panel 33, the flow guide piece 34, the air inlet door plate 5 and the two folding pieces 7 form a semi-closed U-shaped air inlet channel, so that the air flow blown out by the air jet pipe 32 can only flow into the lamp inner cavity; secondly, the heating wire 314 works to heat the air flow in the containing shell 311, and the fan 313 works to blow the heated air flow, thereby starting to heat and accelerate the air flow. The hot air flow is blown out from the air blowing port of the air blowing panel 33 through the air jet pipe 32, blows into the lamp inner cavity through the air inlet, promotes the air flow in the lamp inner cavity to circulate, and transfers heat to the lamp shell 11. This can not only reduce the humidity in the lamp inner cavity and increase the temperature in the lamp inner cavity, but also increase the temperature of the lamp shell 11, thereby reducing the temperature difference between the inside and outside of the lamp inner cavity. At the same time, the air flow is discharged from the air outlet, thereby reducing the humidity in the lamp inner cavity and destroying the condensation conditions of water vapor, so that small water droplets are not formed on the inside of the lamp shell 11. Finally, the first temperature sensor 21, the second temperature sensor 22 and the humidity sensor 23 monitor the values at all times and transmit them to the controller 4. When the lamp inner cavity is in a certain humidity and temperature condition, and the temperature of the lamp shell 11 is higher than the dew point temperature, the anti-fog mode is closed. Refer to Figure 7 , specifically, the fan 313 stops rotating, the heating wire 314 stops heating, the air inlet door plate 5 is controlled to rotate to the closed state, i.e. rotate 90° clockwise, the two folding pieces 7 are folded, and the air blowing panel 33 and the flow guide piece 34 rotate 90° counterclockwise. At this time, the air blowing panel 33, the flow guide piece 34 and the air inlet door plate 5 form a semi-closed Z-shaped air inlet channel, so that the air blowing port of the air blowing panel 33 is rotated to face the lamp outer side, the air inlet door plate 5 is closed to block the air inlet, and the air outlet door plate 6 is closed to block the air outlet. The lamp assembly 1 forms a closed body.

[0066] The fan 313 stops working and no longer sprays gas, and the flow guide 34 has a certain flow guiding effect when the wind speed is less than or equal to 120 km / h; when the vehicle speed exceeds 120 km / h, the controller 4 sends a signal to start the wind resistance reduction mode. The fan 313 starts to work to generate wind, and the airflow in the containing shell 311 is blown out from the air outlet of the air blowing panel 33 through the air injection pipe 32, the airflow is blown from the edge of the lamp housing 11 and adheres to the lamp housing 11 to the rear of the vehicle, and the flow guide 34 also enhances the flow guiding effect. At this time, the airflow separation behind the lamp assembly 1 is reduced, and the wind resistance is reduced. The wind resistance reduction mode can reduce the wind resistance coefficient when the vehicle is running at high speed; when the vehicle is running at high speed, the airflow separation at the lamp assembly 1 increases the wind resistance of the whole vehicle, and the energy consumption is high; the function of increasing the jet flow resistance reduction at the lamp assembly 1 can effectively reduce the air resistance of the whole vehicle and save energy.
