Photometers are specifically designed to measure emitted, reflected or transmitted light in photometric terms of luminousflux, luminance, illuminance or luminousintensity.
光度计是专门用于测量发射，反射或透射光的光通量，亮度，照度或发光强度等。

The luminousintensity, luminousflux and color coordinate of high-power white LED have relations with different place.
研究了在蓝光芯片加黄色荧光粉制备白光LED方法中，色坐标位置对光通量的影响。
