Description

Technical Field

[0001] The present invention relates to the technical field of automobile headlights, and in particular to a modular LED automobile headlight module and a manufacturing method thereof. Background Art

[0002] In the automotive field, headlights are key lighting components, and their performance is directly related to driving safety and driving experience. With the rapid development of the automotive industry and people's increasing requirements for automotive quality, the limitations of traditional automotive headlights have become increasingly prominent.

[0003] From the perspective of heat dissipation performance, traditional car headlights often have poor heat dissipation design, resulting in a large amount of heat accumulation during long-term use. Since LED lamp beads are extremely sensitive to temperature, excessively high temperatures will significantly reduce their luminous efficiency, accelerate light decay, and thus shorten their service life. For example, when driving at night for a long time or turning on the headlights frequently, the internal temperature of traditional headlights will rise sharply, the brightness of the LED lamp beads will gradually decrease, and even flicker or go out, seriously affecting the lighting effect and driving safety.

[0004] In terms of angle adjustment, the angle adjustment function of traditional headlights is often relatively simple or inconvenient to operate. Usually, only simple up and down fine-tuning can be performed, which makes it difficult to accurately adapt to the diverse needs for lighting direction under different road conditions and driving scenarios. For example, when driving on mountain roads, vehicles frequently go up and downhill, and the headlights need to be able to adjust the illumination angle in real time to ensure that the driver can clearly see the road conditions, but traditional headlights are difficult to meet this requirement, which brings many inconveniences and safety hazards to driving.

[0005] Light intensity adjustment is also a major shortcoming of traditional headlights. Its adjustment range is limited and it cannot flexibly adapt to various complex and changing ambient lighting conditions. On rural roads at night with dim light, headlights need to provide strong enough light intensity to illuminate the road surface and surrounding environment in the distance; on urban roads, the surrounding light is relatively sufficient, and excessive headlight brightness may cause glare interference to other road users. However, it is difficult for traditional headlights to quickly and effectively adjust the light intensity in different scenarios. It can neither meet the driver's demand for good lighting effects nor cause traffic safety problems. Therefore, we propose a modular LED automotive headlight module and its manufacturing method to solve the above problems. Summary of the invention
