Description

TECHNICAL FIELD

[0001] The utility model relates to a car light of far and near integrated structure. BACKGROUND

[0002] With the rapid development of global automobile industry and the increasing demand of consumers for automobile performance, automobile safety, driving comfort and the beauty of appearance design have become important standards to measure the quality of a car. As an indispensable part of the car, the performance and technical level of the car light naturally become the focus of attention. As the "eyes" of the driver at night and in bad weather conditions, the car light not only needs to have enough brightness to ensure driving safety, but also needs to have flexible adjustment function to adapt to different driving environments and conditions.

[0003] The car light of far and near integrated structure is an advanced lighting system born in response to this demand. It ingeniously integrates the functions of high beam and low beam into one, and realizes flexible adjustment of light through a precisely designed far and near switching mechanism. This design not only simplifies the structure of the car light and reduces production cost, but more importantly, it enables the driver to quickly and accurately switch the light according to different driving environments and conditions, thereby ensuring driving safety.

[0004] However, the traditional car light design often has shortcomings in terms of heat dissipation effect, light switching flexibility and lighting effect. For example, due to the large amount of heat generated by the electronic components and light sources inside the car light during operation, if the heat dissipation effect is not good, it will lead to a decrease in the performance of the car light, and even cause failure. In addition, the traditional light switching mechanism is often complex in design and inconvenient to operate, making it difficult to achieve quick and accurate light switching. At the same time, due to the unreasonable design of the light source and the reflector cup, the lighting effect of the traditional car light is often not satisfactory, and it cannot meet the demand of modern drivers for high-quality lighting effect.
