采购指南两岸业者攻克大功率LED照明散热难关 » 上接90页能彻底降低总体热阻，让LED的效率更为有效发挥。西安麟字半导体照明有限公司虽然主要从事大功率LED照明产品研发及生产，但该公司在导热材料上亦颇有研究。该公司的技术核心人物─光源设计总工程师魏汉麟所独自设计生产的超高温导热银胶便已获得国家专利，奠定了西安麟字半导体照明在大功率LED封装及散热技术的独到之处。该公司所推出的‘麟字照明’系列产品在LED照明的封装和散热技术方面颇有进展，例如高亮度多芯片集成式封装LED面光源，便具有高效光通量80LM/W、超大功率1W-200W，独特的封装技术可促成低光衰，绝佳的散热技术设计则确保了长寿命。 LED散热技术新方向此外，台湾工研院便积极研发奈米碳球散热涂装粉体技术。基本上，传统的热对流散热方式，是透过增加表面积，然后用风扇去吹，来达到散热效果。不但散热效果差，还需要另外再耗能，此项新技术藉由静电粉体涂布在金属材表面，然后透过将热转变为光能，以红外线辐射的方式进行散热。工研院南分院奈米粉体与薄膜科技中心钟丰元指出，目前测试下来，平均都可以降温达6度以上。不可讳言，LED照明已是不可挡的趋势，而散热技术的进展更攸关普及的速度及范围，可以想见，未来更新及更先进的散热技术将继续出现，以推动LED照明的全面到来。我也要点评相关阅读 • ROHM独创的LED高散热封装技术及最新开发动向 • 设计LED路灯时应该怎样选择恒流模块？ • LED灯具损坏常见原因及保护 HALF PAGE AD (horizontal) 215mm x 139mm 92 国际电子商情 | 2010年11月 | www.esmchina.com http://forum.esm-cn.com/FORUM_POST_1000164006_1200601345_0.HTM http://www.esmchina.com/ART_8800111945_1200_2100_3504_0_cb7c889c.HTM http://www.esmchina.com/ART_8800111294_1200_2701_3504_0_9c780be6.HTM http://www.esmchina.com/ART_8800110826_1200_0_3504_0_076701da.HTM http://www.protronichk.com http://www.protronichk.com http://www.protronichk.com http://www.protronichk.com http://www.esmchina.com
