流明

Featuring dual function HID electronic ballast the low beam 3200 lumen output has a run time of 110 minutes.

具有双重功能的HID电子镇流器低光束3200流明输出有110分钟的运行时间。

And its exceptional lumen output range will allow you to use it in a wide variety of room sizes and ambient light conditions.

其杰出的流明输出范围使得你可以在多变的房间大小和环境光线条件下使用。

Having a lumen output as high as the D935VX's gives the user a lot of flexibility.

有一个像D935VX的为用户提供了很大的灵活性高流明输出。

This light should be world's first single LED flashlight whose lumen ouput exceeds 1000 lumens.

也是人类历史上第一个超过1000流明的单LED手电筒。

This increase in lumen output is useful if you wish to use a screen larger than 100 diagonal, or if you have some ambient light in your projection environment that cannot be removed.

流明输出，这在增加有用的，如果你想使用大于100的屏幕对角线，或者如果你有你的投影测量周围环境的光，无法删除。

Contrast on the screen was again improved, with virtually no cost in lumen output.

在屏幕上再次提高对比度，几乎没有流明输出的成本。

One lux equals toone lumen of flux over an area of one square metre.

照度的单位。1流明的光通量分布在一平方米的面积上，其照度为1勒克司。

If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons. So LW white LED radiation power output has to consume 1.51 W electric powers and the luminous flux efficiency limitation of electrical to optical conversion for the white LED is 197.8lm/W at above condition.

在理想情况下，注入一个电子－孔穴对产生一个蓝光光子，设荧光粉的量子效率为1，因此，注入的电子－孔穴对数亦等于白光光子数，进而计算出白光LED每辐射1W的光功率所需的电功率为1.51W，上述白光LED发光光谱对应的白光LED的电－光转换的理论极限流明效率为197.8lm/W。

The result showed that the luminous flux for LW white LED radiation power output is 298.7 lm and the total photons are 2.7×1018. If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons.

The Bridgelux Arrays used in the Helieon Sustainable Light Module deliver between 500 and 1,500 operational lumens (performance comparable to or greater than 40 to 75 Watt incandescent bulbs) in a compact high flux density light source. These integrated solutions deliver high quality light without pixilation, closely replicating the beam quality of traditional light sources.

Helieon长寿光源模组所应用到的Bridgelux距阵介于500到1500流明（亮度相当于或超过40W~70W的节能灯泡），光源设计紧凑，亮度高，而且光效好无闪烁，非常接近于传统光源的光效。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
