摘要：目前越来越多的车型在采用氛围灯来调节汽车内饰照明环境，可以通过车速、环境以个人喜好进行灯光亮度和颜色的调节，以提高车内人员的舒适度。但由于氛围灯常常布置与车内多个位置，对于单个或多个氛围灯的光品质和光色一致性控制显得尤为重要。

本文以人眼视觉对亮度、色度感受为基础，结合ProMetric高分辨率成像色度计对氛围灯的测试案例，简单阐述汽车氛围灯亮度、色度、均匀度等光品质主观评价客观化的一种方法和效果，提高氛围评价效率和精度。此方法亦可拓展到内饰背光、外饰照明灯具的光品质评价。

Abstract: At present, more and more car models in the use ofambient light to adjust the interior lighting environment, through the speed,the environment and personal preferences to adjust the brightness and color oflight to improve vehicle comfort. However, since the ambience light is oftenarranged in a plurality of positions in the vehicle, it is particularlyimportant to control the light quality and light color consistency of thesingle or plural ambient lights.

In this paper,based on the human visual perception of brightness and chroma,combined with ProMetric high-resolution imaging colorimeter on the test case ofambient light, simply described the car ambient light brightness, color,uniformity and other light quality objective evaluation of the test Methods andeffects, to improve the efficiency and accuracy of the ambient light lightingeffect evaluation. This method can also be extended to interior lighting,exterior light lighting quality evaluation.
