　　為照明解決方案增加智能和靈活性

　　照明是大多數(shù)人習(xí)以為常的一種舒適。簡(jiǎn)單地翻轉(zhuǎn)開(kāi)關(guān)的能力——不考慮燈泡背后的技術(shù)——是照明工程師所不具備的奢侈品。目前，照明約占全球電力消耗量的四分之一，發(fā)達(dá)國(guó)家正在通過(guò)“綠色”立法，以減少能源消耗，減少對(duì)環(huán)境的關(guān)注。隨著照明越來(lái)越受到重視，照明工程師需要利用傳統(tǒng)白熾燈的高效照明替代品。

　　當(dāng)今最高效的照明替代品的前沿是LED和緊湊型熒光燈（CFL）技術(shù)。事實(shí)上，后者已經(jīng)有將近20年但最近業(yè)界一直無(wú)法擺脫的壞名聲，早期的節(jié)能燈已獲得。在瘋狂的最初搶購(gòu)產(chǎn)品到消費(fèi)者手中，并以最低的成本，緊湊型熒光燈制造商削減了許多角落，最終犧牲質(zhì)量。早期的緊湊型熒光燈啟動(dòng)很慢，產(chǎn)生了一種很“冷”的閃爍的光。今天的共識(shí)是，這樣一個(gè)質(zhì)量低劣的污名確實(shí)給整個(gè)行業(yè)帶來(lái)了沉重的代價(jià)。只有這樣的產(chǎn)品更多的新一代電子鎮(zhèn)流器，使用改進(jìn)的啟動(dòng)時(shí)間和減少閃爍在改善熒光粉產(chǎn)生溫暖的光相結(jié)合，已經(jīng)能夠贏(yíng)得一個(gè)心灰意冷的公共性。

　　LED technology has the potential to repeat the same mistakes. The pressure to reduce the cost of the solution is perhaps even higher， and it is for this reason that several governmental initiatives have been introduced to avoid falling in the same trap.［1］［2］［3］ It would be such a pity， because LED lighting promises to provide a much better lighting alternative under almost any possible point of view. LEDs do not require the presence of toxic materials such as Mercury， which is present in each fluorescent lamp. They have virtually no start time and can be made to produce a warm and pleasant light. In fact， LED lamps can easily provide any color temperature （Correlated Color Temperature［4］［5］） required， and are even adjustable on fly. LED lights can be dimmed easily， and can provide an extremely long service life （up to 50，000 hours） with an efficacy that is already superior to that of the best competing technologies. Yet， contrary to the other lighting technologies， they do always require the use of electronics.
