luminous flux

1 Device in which the phenomenon of reflection is used to alter the spatial distribution of the luminous flux from a source.

利用反射现象来改变光源光通量的空间分布的装置。

2 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。

3 Ratio of the absorbed radiant or luminous flux to the incident flux.

吸收的辐射通量或光通量与入射通量之比.
