The invention relates to automobile lighting, in particular to a lighting device capable of stably achieving an automobile low beam III area, which comprises a light source, a condenser assembly and a light source driving system, the light source and the condenser assembly are fixedly mounted on a radiator, and a circuit board attached to the radiator is arranged among the light source, the condenser assembly and the radiator. A lens support is fixedly installed at the front end of the light source and condenser assembly, and a lens is installed at the front end of the lens support. The light source and condenser assembly comprises a low-beam light source and a low-beam condenser assembly which are used for irradiating a low-beam I area, a low-beam II area and a low-beam IV area, and a light supplementing light source and a light supplementing condenser assembly which are used for irradiating a low-beam III area, and the light source driving system conducts independent current adjustment on the light supplementing light source in the light supplementing light source and the light supplementing condenser assembly so as to adjust the illuminance of the low-beam III area. According to the technical scheme provided by the invention, the defects that the illuminance of the low-beam III area cannot be accurately controlled and the device cannot be suitable for headlamps with different shapes can be effectively overcome.
本发明涉及汽车照明,具体涉及一种稳定实现汽车近光III区的照明装置,包括光源和聚光器组件,以及光源驱动系统,光源和聚光器组件固定安装于散热器上,光源和聚光器组件、散热器之间设有贴附于散热器上的电路板,光源和聚光器组件的前端固定安装有透镜支架,透镜支架的前端安装有透镜;光源和聚光器组件包括用于照射近光I区、II区、IV区的近光光源和近光聚光器组件,以及用于照射近光III区的补光光源和补光聚光器组件,光源驱动系统通过对补光光源和补光聚光器组件中的补光光源进行单独电流调节以调整近光III区的光照度;本发明提供的技术方案能够有效克服不能精准控制近光III区的光照度、无法适用于不同造型前照灯的缺陷。
