目前，國(guó)際上的LED標(biāo)準(zhǔn)發(fā)展趨勢(shì)正逐漸靠向了三個(gè)重要的點(diǎn)： </p> <p> 一，越來(lái)越重視性能、測(cè)試方法標(biāo)準(zhǔn)的制定。由于LED具有與傳統(tǒng)照明光源截然不同的空間發(fā)光特性，使原本適用于傳統(tǒng)光學(xué)特性測(cè)量的方式未必適用于LED，如光通量、光強(qiáng)以及色度測(cè)量，否則LED的測(cè)量精度以及準(zhǔn)度都將面臨很大的困難; </p> <p> 二，越來(lái)越注重能效與性能標(biāo)準(zhǔn)的制定。由于全球照明用電量占全年總用電量的20%，其中有多達(dá)90%的電能被轉(zhuǎn)換成熱能消耗，在節(jié)能環(huán)保的考量下，LED照明已經(jīng)快速成為頗受關(guān)注的技術(shù)和產(chǎn)業(yè); </p> <p> 三，越來(lái)越重視LED燈具標(biāo)準(zhǔn)的制定。LED燈具是指包括基于LED的發(fā)光元件和匹配的驅(qū)動(dòng)器以及配光部件、固定和保護(hù)發(fā)光援建的部件以及將器具連接到分支電路部件的完整照明器具。傳統(tǒng)光源一般是單個(gè)發(fā)光體，而LED燈具使用的是LED燈是由多個(gè)發(fā)光體組成并發(fā)光的，LED燈具的發(fā)光體之間存在顏色差異性，所以需要使用色空間均勻度去評(píng)價(jià)LED燈具顏色的空間分布情況。
