total luminous flux

the led total luminous flux decreases with the increase of time in the dc mode, but it does not change in the pulse mode.

LED总光通量在直流模式下随点燃时间下降，在脉冲模式下则不随点燃时间变化。

The experimental results are that the power and total luminous flux are in-creased when the neon component of mixture gases is increased, but the efficacy of the com-pact fluorescent lamps is reduced and lamp voltage is enhanced to be up 5-30%.

实验结果显示，当充入混合气体中氖气比例上升时，灯的功率和总光通量上升，灯的工作电压也上升5～30%，但是灯的光效下降；

among the many technical indexes of led, the total luminous flux is one of the most important.

在LED的诸多技术指标中，总光通量是其中最重要者之一。
