Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicle lamps, and particularly relates to a fog-proof vehicle lamp based on heat balance and a heat dissipation circulation control system. BACKGROUND

[0002] With the development of new energy vehicles, intelligent vehicle lamps are widely used. The intelligent vehicle lamps all adopt LED light sources. Compared with the original halogen light source, the heat of the LED lamp bead is mainly conducted to the substrate in the form of heat conduction at the welding point, and then dissipated, which causes the heat of the vehicle lamp to be concentrated and the heat to be unevenly distributed in the lamp. These all aggravate the fogging of the vehicle lamp. The fogging of the vehicle lamp can cause the brightness and effective projection distance of the light to decrease, reduce the visibility of the current vehicle position and driving direction for other vehicles and pedestrians, and seriously endanger the driving safety.

[0003] In order to reduce the fogging of the vehicle lamp, one of the current anti-fog measures is to deploy and install a heat dissipation fan in the vehicle lamp. The heat dissipation fan can quickly increase the gas circulation speed in the lamp and balance the heat distribution in the vehicle lamp, so as to reduce the fogging in the lamp. However, due to the complex and narrow shape of the new vehicle lamp, the small space in the lamp cannot accommodate a large fan, and the mechanical structure of the fan can fail in a long time of use of the vehicle, which cannot effectively balance the heat distribution in the vehicle lamp.
