In figure 4 using a collimated source the lightpipe is 85 % efficient 在插圖4中使用平行光源至光管,其有效率達(dá)85%。
Older lightpipe applications have typical throughput of 20 to 30 percent 較早的光管應(yīng)用有20到百分之30的典型生產(chǎn)率。
It has now been proven that using software simulation reduces lightpipe design costs by 30 to 50 % 現(xiàn)下已經(jīng)證明使用軟體仿真使光管設(shè)計(jì)費(fèi)用減少了30%到50%。
Used in an application where you are trying to funnel this source into a lightpipe can be tricky and coupling inefficient 在一些應(yīng)用中你會(huì)發(fā)現(xiàn)它是難處理和耦合效率不佳的去嘗試將光注入光管。
In figure 3 the led source is too dispersive and there is a large light loss at the bend providing only 25 % efficiency in the lightpipe 在插圖3中l(wèi)ed光源太分散而且有很大的光損失在彎曲部份,這亦使得光管僅能提供25%的效率。
