style="text-indent:25px">在一些24小時(shí)連續(xù)工作的場地，例如地下停車場、24小時(shí)加班生產(chǎn)的工廠等地方。節(jié)電也是十分重要的。如上所述，- -根T8的LED日光燈大約可以節(jié)省20瓦電，一年下來就可以節(jié)省20x365x24/1000=175.2度電。假如以每度電0. 7元計(jì)算，那么一年下來，可以節(jié)省電費(fèi)122.64元，兩年下來，就可以節(jié)省出這根LED日光燈的成本。以后所節(jié)省的電費(fèi)就成為純收益了。所以現(xiàn)在國外有一種稱之為EMC (能源管理合同Energy ManagementContract)作法。就是由一家財(cái)團(tuán)或銀行出資。替一個(gè)地下停車場或商場**安裝LED日光燈，但是要向業(yè)主收取所有節(jié)省下來的電費(fèi)，協(xié)議有效期可能為5年。只要2年以后，就可以回收所有投資，第三年開始，所有節(jié)省下來的電費(fèi)就變成是純收益了。這是一個(gè)十分有利的投資項(xiàng)目。國內(nèi)也開始有人這樣做了。更何況按照Haitz定律，LED的價(jià)格每十年將降低十倍!</p><p style="text-indent:25px">線性調(diào)節(jié)zui簡便的方法是在LED驅(qū)動(dòng)控制C中使用外部SET電阻來實(shí)現(xiàn)LED的調(diào)光控制。雖然，這種調(diào)光控制方法有效，但卻缺乏靈活性，無法讓用戶改變光強(qiáng)度。線性調(diào)節(jié)則會(huì)降低效率，并引起白光LED朝向黃色光譜的色彩偏移?？赡苁禽p微的偏移,但可在敏感應(yīng)用中檢測出。采用數(shù)字或叫PWM的LED調(diào)光控制法以大于100HZ的開關(guān)工作頻率，以脈寬調(diào)制的方法改變LED驅(qū)動(dòng)電流的脈沖占空比來實(shí)理LED的調(diào)光控制，選用大于100HZ開關(guān)調(diào)光控制頻率主要是為了避免人眼感覺到調(diào)光閃爍現(xiàn)象，在LED的PWM調(diào)光控制下。<span
