點亮全球LED照明標準新時代

經濟部技術處邀各界參與「研討LED標準草案公聽會」

(中央社訊息服務20090501 09:58:47)綠色環保所觸發之節能減碳愛地球風潮，帶動著全球LED照明市場的日趨活絡，其相關標準之制定亦備受國際關注且刻不容緩，為引領我國業者搶攻全球照明市場，在經濟部近二年的大力推動及各界的擁護支持下，台灣第一套「LED照明標準」及全球首篇「LED路燈照明燈具國家標準」，日前已由技術處科專計畫所支持，召集國內LED上中下游相關業者所共同成立之「LED照明標準與品質研發聯盟」所制訂完成。

本標準草案內容含括上游晶粒、中游封裝乃至下游應用等共計17種標準規範，預期此標準之制定完成，將可逐步提升我國LED產業技術水準，擴大整體內需市場，並可協助我業者開拓中國大陸照明市場進軍國際，創造無限商機。

為落實我國LED之標準確為產業所需並與國際接軌，經濟部技術處將於本(98)年5月13日中午12時40分假台北集思國際會議中心，召開「研討LED標準草案公聽會」，將針對「發光二極體晶粒加速壽命試驗方法」等8種標準草案內容解說並進行討論，該會議由經濟部技術處吳明機處長擔任主持人，邀集產、官、學、研各界代表共同與會，台灣區照明燈具輸出業同業公會吳照麟理事長、工研院電光所詹益仁所長及黃勝邦經理擔任與談人，從學理、技術、實務及法律等面相與現場來賓進行議題討論及意見交流，使所制定之標準內容更臻完善，以利後續由技術處與標檢局共同推動成為CNS國家標準。

由於歐美日韓及中國大陸亦紛紛投入LED標準制定工作，未來標準規範之建置與推動將成為決定LED照明戰爭勝負的關鍵因素。有鑑於此，經濟部已於本(98)年1月22日公布「發光二極體元件光學與電性量測方法」等4種CNS國家標準。為使台灣LED標準及技術水平大幅提升，以利加速我國LED產業逐步躍升國際舞台，「LED 照明標準與品質研發聯盟」透過執行經濟部技術處業界科專「LED照明標準與品質研發應用整合計畫」所制定之17種標準規範如高效率(大於 100Lm/W)、長壽命(大於20,000小時)LED T-Bar室內照明燈具、LED路燈及LED投光燈具等，藉以健全我國LED產業技術內涵。未來，經濟部更將以此制定完成之各項國家標準為籌碼，與中國大陸協商制定兩岸LED產業共同標準及交互認證機制，進而建立大中華產業共同價值鏈，並期進軍國際LED照明市場，開啟我國LED照明產業新契機。

經濟部技術處除辦理本次研討LED標準草案公聽會廣納各界意見外，亦將標準草案內容置於技術處網站首頁(doit.moea.gov.tw)供民眾參閱及下載並祈惠賜卓見，以使台灣LED產業標準內容更臻完善。
