综上所述，减少电压5%能使灯泡的使用寿命延长至少2倍，但是其亮度会下降20%。
The net result is that a 5% reduction in the voltage more than doubles the life of the bulb, but delivers 20% less light.
如今首批设计的民用电网电压的能直接替代白炽灯泡的发光二极管已陆续上市.
Now the first mains-voltage LEDs designed as direct replacements for incandescent bulbs are arriving on the market.
就像你家里的，手电筒，你有时必须，放几个电池，来达到一个更高的电压，以此点亮一个小灯泡。
Just like with your flashlight that you have at home, you sometimes have to put in several cells in series to get a higher voltage so that you can power a small light bulb.
反之，当工作电压升值16时，灯泡的寿命和电压成反比。
By contrast, the bulb's lifespan is inversely proportional to the voltage raised to the power 16.
如图所示每个灯泡的电流和电压之间的关系并不是线性的。
As is seen, the relation between the voltage and the current in each lamp is other than linear.
使用LED灯泡-这些LED灯泡提供强光照明但同时减少了电压负荷。
LED bulbs will be used - they give stronger light output with reduced voltage requirements.
拆除和更换电压调节器和电池像更换电灯泡一样容易。
Removal and replacement of the voltage regulator and battery is as easy as changing a light blub.
一个小灯泡发出的热能和光能的比例是怎样由给小灯泡的电压所决定的？
What is the ratio between the thermal energy and light energy emitted from a small electric bulb depending on the voltage applied to a bulb?
电源为AC： 85V- 265v，全世界通用电压，9瓦的耗电量，亮度相当于90瓦的普通灯泡的亮度。
Power supply AC: 85v-265v, Universal worldwide voltage, 9 watts of power, equivalent to 90 watts of ordinary light bulb brightness.
