1.高亮度LED高亮度產品始自1980年推出紅色高亮度LED，之後日本即開始將其應用於戶外看板、第三煞車燈等。目前延伸應用已擴及至大型全彩化看板、車燈、照明與交通號誌之上。目前高亮度LED逐漸普及，但全彩化看板與交通號誌上的應用尚無法成為主流。雖然全彩化看板因具有廣視角、易施工、高精細等優點，但藍色LED價格偏高為應用上的主要瓶頸﹔而使用紅、黃、綠色高亮度LED之交通號誌雖然具有易辨識、低耗電與低維修之優點，但仍應朝降低售價方向努力﹔而利用橘紅色AlInGaPLED製作之第三煞車燈較不刺激眼睛，歐洲甚至已有少部分高級汽車利用高亮度LED製成車燈模組，故未來發展潛力大。2.白光LED白光LED具有發熱低、省電、壽命長、體積小等優點，未來成本進一步降低，極有機會取代目前的照明設備。估計到2003年時，約可達到2.7億美元的市場規模，顯示此一產品具有相當大的市場爆發力。3.IRLED隨著可攜式電子產品(如PDA、筆記型電腦、行動電話等)要求無線傳輸功能之後，支援IrDA傳輸協定的產品將成為商品化的重心，故紅外線LED具有長期成長潛力。4.SMD由於通訊或電子產品均邁向輕、薄、短、小之趨勢，因此各式表面黏著之產品均可逐漸成長。SMDLED具備體積小、適合自動化生產之優點，故在大哥大逐漸普及之際將廣被應用。
