[0002] With the development of new energy vehicles, smart headlights are widely used. Smart headlights all use LED light sources. Compared with the original halogen light sources, the heat of LED lamp beads is mainly transferred to the substrate by heat conduction at the solder joints, and then dissipated, resulting in concentrated heat in the headlights and uneven heat distribution in the lamps. All these aggravate the fogging of headlights. The fogging of headlights will cause the brightness and effective projection distance of the lights to decrease, reduce the visibility of other vehicles and pedestrians to the current vehicle position and driving direction, and seriously endanger driving safety.

[0003] In order to reduce the fogging of headlights, one of the current anti-fogging measures is to install a cooling fan inside the headlight, which can quickly increase the gas circulation speed inside the headlight and balance the heat distribution inside the headlight, thereby reducing the fogging inside the headlight. However, since the shape of new headlights is usually more complex and narrow, the space inside the headlight is small and cannot accommodate a large fan. In addition, the mechanical structure of the fan may fail during long-term use of the vehicle, and it cannot effectively balance the heat distribution inside the headlight.

[0004] In order to solve the problem of heat concentration in the narrow space of the headlight and difficulty in effectively balancing the heat distribution for a long time, an anti-fog headlight and a heat dissipation circulation control system based on heat balance are proposed.
