style="text-indent:25px">在一些24小時(shí)連續(xù)工作的場(chǎng)地，例如地下停車場(chǎng)、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(lái)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(lái)，可以節(jié)省電費(fèi)122.64元，兩年下來(lái)，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(guó)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(chǎng)或商場(chǎng)**安裝LED日光燈，但是要向業(yè)主收取所有節(jié)省下來(lái)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(kāi)始，所有節(jié)省下來(lái)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(guó)內(nèi)也開(kāi)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
