光亮度光亮度Luminance光亮度(luminanCe)光亮度是任何面光源在垂直于给定方向的单位投影面积上的发光强度。国际照明委员会把它定义为，含有被研究点的无限小的面积元在给定方向上的发光强度除以该面积元在垂直于该方向的投影面积所得的商。简单地说，光亮度是每单位面积上的发光强度，光亮度又称光度学亮度。因为烛光是发光强度的单位，面光源的光亮度就可以用烛光/厘米2、烛光/英寸2等单位表示。用数学式表示光亮度B一dl/dAcos夕，式中夕为观察线和面光源表面垂线间的夹角，八为面光源面积，I为发光强度。参阅“流明”(1 umen)、“发光强度，，(luminous intensity)条。熙提(s tilb)也是光亮度的单位，等于1烛光/厘米2。欧洲国家常用它，但在美国直接用烛光/厘米2。在欧洲，有时使用另一个单位阿熙提(a postilb)，它等于以1流明/米2的比率发射或漫射光的全漫射面的光亮度。参阅“光度学”(photometry)条。[普特南(R.C，putnam)撰]
