    中國LED行業發展展望

     

    目前,全球LED產業投資是很熱的一個重點項目,各國對 LED的研發生產都比較重視。日本已經實現1998-2002年耗費50億日元推行白光照明,整個計劃的財政預算為60億日元。美國2000年制定的“下一代照明計劃”被列入了能源法案,計劃從2000-2010年,投資5億美元,用LED取代55%的白熾燈和熒光燈,預計到2025年,固態照明光源的使用將使照明用電減少一半,每年節電額達350億美元,形成一個每年產值超過 500億美元的半導體照明產業市場。我國也正在加快LED發展的步伐。 中國是電子制造業大國,并且正在迅速發展,國內的手機、汽車等產業是LED發展的巨大推動力,而且隨國家半導體照明工程的發展,國內LED產業具有廣闊的發展前景。未來5年,我國也將把半導體照明作為一個重大工程進行推動;而科技部也已批準上海、大連、南昌、廈門、深圳、石家莊、揚州7地作為LED 產業化基地。

     

    今后,LED汽車照明需求將穩定增長。

     

    隨著手機市場增長幅度趨緩,LED市場增長動能將轉為筆記本電腦背光源、顯示廣告牌、照明等其它應用領域。在汽車照明方面,LED長期需求將呈穩定增長。

     

      由于LED價格的下跌及發光效率提升,使得LED在車輛應用從車內照明,發展到第3煞車燈、方向燈、尾燈,并于2008年在高級車導入頭燈應用。目前,LED燈發光效率已有高過廣泛使用的傳統車頭燈表現,代表LED車頭燈有機會正式邁入商業化,中介價格仍較高,因此短期內仍將僅配置在高階車款。

     

    近兩年,隨著LED發光效率提升及價格下跌,產品應用范圍也更加寬廣,Netbook已大量搭載LED作為背光源,而LED路燈及景觀照明應用也將繼續蓬勃發展。

     

    未來,超薄電視基本上都采用LED背光技術。

     

      隨著平板顯示技術的不斷提升,超薄電視還會更薄。從目前市面上看,超薄電視基本上都是采用了LED背光,LED業界學名為發光二極管,早在20世紀60年代誕生后就被認定是下一代照明應用光源。

     

      LED光源不僅使電視厚度和重量均實現大幅度減少,同時還擁有更高的可靠性和穩定性。在發光壽命方面,不同CCFL的額定使用壽命(半亮)在8000~100000小時之間,而LED則可以達到CCFL的兩倍左右。LED電視的使用壽命可達10萬小時。如果按每天開機5小時計算,一臺LED電視可以使用將近55年。

     

    自2008年下半年以來,各大平板電視廠商開始把LED電視作為高端產品進行大力推廣,如三星、夏普、索尼、海信等品牌都先后發布了采用LED技術的新品。在2009年CES展上,無論是三星、索尼、LG等日韓企業,還是海信、康佳、海爾等中國企業,都展出了各自的LED電視。前段時間,國內彩電企業海信還宣布建立了一條LED模組生產線,此后,清華同方也表示將募資20億元重點投入LED,這些廠商在LED領域的投入,必將快速實現成為主流的夢想。

     

    除了LED之外,目前在電視領域還有OLED,OLED是有機發光二極管,又稱為有機電激光顯示因為具備輕薄、省電等特性。不過OLED尚面臨諸多技術和生產成本方面的問題,OLED至少還需要4到5年時間才能進入市場。而從這一趨勢來看,超薄電視僅剛剛起步,未來超薄電視將更薄、畫質更出色、壽命更長。

     

    總體來看,中國未來LED市場將會持續增長。這對中國從事照明軟磁鐵氧體磁心生產企業的企業來說是個很好的市場機會。
