Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically a vehicle daytime running light module that facilitates heat dissipation. Background Technology

[0002] With the increasing demands for automotive intelligence and safety, the performance of automotive high and low beam daytime running light modules, as a core component of the vehicle lighting system, directly affects driving safety and driving experience. In recent years, LED light sources have been widely used in the automotive lighting field due to their advantages such as high efficiency, energy saving, long lifespan, and fast response speed, gradually replacing traditional halogen and xenon light sources as the mainstream. However, LED chips generate a lot of heat when operating at high brightness. If heat cannot be dissipated in a timely and effective manner, it will lead to an increase in chip junction temperature, which in turn will cause problems such as light decay, color temperature drift, and shortened lifespan, and may even cause light source failure, seriously affecting driving safety and lighting effect.

[0003] Currently, traditional automotive high and low beam daytime running light modules have many shortcomings in heat dissipation design: poor air circulation and the sealed structure of the lamps result in poor internal airflow, making it difficult to form effective convection heat dissipation. In particular, integrated modules that combine high and low beams and daytime running lights have multiple light sources concentrated in one location, causing heat to accumulate. The traditional closed design exacerbates the heat accumulation problem. In addition, with the development of automotive intelligence, the functions of car lights are constantly being integrated and improved, such as intelligent dimming and dynamic flowing effects. This places higher demands on the stability of the electronic components inside the lamps. Poor heat dissipation can seriously affect the performance of electronic components, leading to functional failure or abnormality. Therefore, developing an efficient, compact heat dissipation technology that is adaptable to multiple application scenarios has become the key to improving the reliability and performance of automotive high and low beam daytime running light modules, and is of great significance for ensuring driving safety and extending the service life of lamps.

[0004] Based on this, a car daytime running light module with convenient heat dissipation is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
