Another attribute is the flux or radiant power that can be delivered in that narrow frequency band . 另一个性质就是在这样窄的频带内可以给出很高的光通量或辐射功率。
The brightness or luminance of an object is defined as the luminous flux emitted per unit area of the object into unit solid angle . 物体的亮度或发光率定义为物体面积发射到单位立体角内的光通量。
Flux : the stream of photons coming from a light source 光通量:一个光源的光量子流量。
