摘　　要：研究投射式LED前照灯色度性能,以便引导其健康发展。按照GB 25991—2010实验条件对5款LED前照灯进行光色及显色性测试,发现光色及显色性存在比较严重的空间分布不均匀现象。分析引起色空间分布不一致性的原因,并提出光学设计的改进措施。The chromaticity performance of projecting LED headlamps was studied so as to guide its healthy development. According to GB 25991-2010 regulation, five LED headlamps were tested for light color and color rendering, and it was found that there was a serious uneven spatial distribution of light color and color rendering. Then the cause of inconsistency of color space distribution was analyzed, and the improvement measures of optical design were proposed.
