The invention relates to a road projection lamp system for a vehicle and a method for controlling road projection. The variable-chromaticity road projection lamp system applied to the vehicle is composed of a variable-chromaticity lamp, and the variable-chromaticity lamp radiates road surface radiation content. The road surface radiation content is generated by reflecting light emitted from a first projection light emitting diode (LED) of warm white and a second projection LED of cold white at an inclined angle with a projection beam from a chromaticity variable road projection, the first projection light emitting diode (LED) of warm white and the second projection LED of cold white being disposed in a direction symmetrical to the DMD, and radiate the low beam by comparing the warm white color of the first lamp LED and the cold white color of the second lamp LED to the road surface radiation content in chromaticity.
本申请涉及一种用于车辆的道路投影灯系统及控制道路投影的方法。应用于车辆的色度可变型道路投影灯系统由色度可变灯组成,色度可变灯辐射路面辐射内容,路面辐射内容是通过利用来自色度可变道路投影的投影光束以倾斜角度反射从暖白色的第一投影发光二极管(LED)和冷白色的第二投影LED发射的光来生成的,暖白色的第一投影发光二极管(LED)和冷白色的第二投影LED设置在与DMD对称的方向上,并且通过在色度上将第一灯LED的暖白色和第二灯LED的冷白色与路面辐射内容进行比较来辐射近光。
