该系统首先给出LED的相对光谱功率分布，据此计算出LED的总光通量等光、色参数。
On basis of the spectrum distribution, we can calculate the optical and colorimeter parameter of LED such as CIE color coordinate, color temperature, color rendering index and so on.
当充入混合气体中氢气比例上升时，灯的功率和总光通量下降5～10％，灯的工作电压也下降。
If the krypton component of mixture gases is filled, the power and total luminous flux of compact fluorescent lamps will be reduced to be down 5- 10%, and the lamp voltage is also reduced too.
