汽车智能表面之反射式氛围灯同色表皮的不同光色表现探究

汽车内饰的CMF(颜色、材料、饰面)设计在过去几十年里经历了重大变革。随着科技和设计理念的发展,汽车内饰在过去几十年发生了巨大的变化。过去,汽车内饰设计主要关注物体色,即在平常光线下的颜色表现。设计师们注重选择适合车辆整体风格和品牌定位的颜色方案。然而,随着人们对于车内环境舒适度的要求提升,内饰氛围灯被广泛应用,光源色的影响开始受到关注。光源色在不同光照条件下会改变物体色的外观,因此设计师们需要考虑光源色对于颜色表现的影响,同时也需要考虑光源色与物体色评价标准的不同。


在光学领域存在这样一个备受关注的现象,将两个在D65标准LED光源下颜色表现一致的物体放置到不同光色下观察其颜色表现。这在色度学中被称为同色异谱现象。

由图像上可以看到,在正常照明下色彩表现一致的物体,在不同的光色的照射下产生了不同程度的色差(上图蓝色色差最大,红色色差最小),这种现象的会对产品的CMF设计产生较大的影响。通常在进行CMF的设计过程中,设计人员会通过Lab值进行颜色的管控。即使是不同材料的内饰件也可以通过LAB值的管控实现内饰的设计与生产的一致与统一。


而在汽车内饰中引入光源后,事情发生了改变,灯光与内饰材料的结合,很难通过材料层面的Lab值定义进行管理。


深究其原因,传统内饰CMF中使用的Lab表色系统是物体色评价系统,是物体在D50或D65等标准光源下的色度表现。而在智能表面等氛围灯的颜色设计和评价中,智能表面是作为二次光源被人眼所感知的,其最终表现依照明光源的不同而不同。在光源色中,关注的是光源本身所发出的颜色,因此,应该采用CIE 1976Lu’v’作为色彩评价的表色系统。在CIE 1976 Lu’v’表色系统中,亮度(L)表示光源的明亮程度,u’和v’表示了该光源发出的颜色的绿红和蓝黄成分。


事实上,国际照明委员会CIE在2014发布的技术备忘录CIE TN 001:2014中明确推荐在发光体的颜色评价中,应当使用CIE1976Lu’v’表色系统来评价发光体的色差。

那么针对于上文提及的现象,我们应当如何通过CIE1976表色系统实现对色差的管控呢?已知不同材料在不同光色的呈现效果并不一致,要想实现一致的呈现效果,需要使用u‘ v’进行光源色的重新定义,并引入光色校准算法对光色进行校准。

我们选取了一款在按照氛围灯特定颜色照射下会产生较大色差的产品进行校准,不难发现经过校准后的产品反射面,会比原始状态更接近目标色的要求。

此时我们再对两个不同的产品进行相同颜色的点亮,可以看见,即使是在较为蓝色的区域也使得两款产品实现了色彩表现上的一致。
