目前室內照明燈具樣式繁多,但未必皆是屬節能的產品,因其外觀及照明特性難以藉由目視判定優劣,一般消費者或專業設計師皆然。如何在其多樣性中挑選適用於節能與具品質的燈具,便成為目前室內設計師與消費者所關心的課題,故有必要進一步深入探討,以明確掌握燈具之節能效益。 本研究首先就理論進行討論,擬定照明節能相關之15項定量變數,其中包含「光度」、「色度」、「價格」、「電性」及「照明品質」等參數,作為室內辦公室照明燈具之節能評比項目。最後,將各項數據輸入多元屬性評量軟體MDPREF,進行多變量統計,以掌握燈具樣品之優劣排序。經過比較後發現,目前最符合照明節能及品質要求之燈具為傳統光源T5螢光燈以及新式電光源白光LED燈具。尤其白光LED燈具在過去兩年出現長足的進步,例如先前在光源演色性及發光效率等為人詬病的問題,目前皆逐漸改善,有與傳統光源並駕甚至超越之勢。
Nowadays, there are many types of indoor lamps, but not all of them are energy-saving products. It’s difficult for consumers and designers to judge which is better by observing their appearance. Therefore, how to choose a good product has become a important issue. Based on this, a further study of evaluating energy-saving lighting is necessary. As an attempt to estabilish a energy-saving standard as a referance to evaluate lightings, this research developed 15 variables and analyzed these documents by a multidimensional scaling method (MDPREF).The result shows that the T5-fluorescent lamps and the White-light LED meet the needs of energy-saving and lighting quality most. It is noteworthy that White-light LED had made a great progress in the past two years, eapecially the imporvement in color rendering ability and Luminous efficiency.
