超短焦高均勻性之LED投射光源研製

由於發光二極體具有壽命長、體積小、指向性發光特性等優勢，且發光效率進步快速，已開始大量使用於照明燈具設計，且因發光二極體某些光源之特性，如指向性等等，並不同於傳統光源的發光特性，若是採用傳統燈具的作法，將不易發揮發光二極體光源的特色，反而降低發光二極體燈具的發光效率，增加燈具成本與體積。本論文希望探討立體封裝發光二極體技術以立體封裝之優異光學性能，針對發光二極體配光之性能加以發揮，達成短焦距、高均勻性之長好光源，並針對此封裝技術之主要缺點，發光二極體晶片的散熱問題，利用新的主、被動散熱材料及技術，分別為固態風扇及微熱導管，加入原有之立體封裝裝置之中，以將發光二極體晶片上累積的熱能加以導出、擴散至周圍大氣環境中，以達到降低溫度、提高光效及延長壽命，如此，才可以完成發光二極體光源實際應用於照明產品之機會。

Base on the advantages, like long life ,impact size, highly directional light and the efficacy improved rapidly. LEDs already can server for lighting luminaries well for human life. But in some performances, like directional light output, LED is totally different with traditional light sources. If we design a LED luminary with traditional way then we can’t show the merits of LED out and even decrease the efficiency and increase the volume and cost for LED luminary. The paper want to discuss about a LED projection lamp with cubic LED package and Micro Heat transmitter and solid state Fan technologies. Base on these three technologies we want to practice the LED luminary with a ultra short focus and large uniform light area .we don’t need the secondary lens, so ,efficiency loss for light is small. We adapt the thermal technologies ,like ”Micro Heat transmitter” and “Solid state fan” ,let we can get a good thermal solution for LED to guarantee we will have a good performance and reliability LED light source.
