摘要
本研究係實現分離式綠能高功率發光二極體球泡燈具模組，將燈具模組分為LED光源及以及驅動電路兩部分，防止其散熱交互影響，各自設計出兩部分之散熱主體，與傳統式LED燈具相較而言，因其分屬兩部之壽命不同，可各自更換新品，具降低成本與有效利用資源之設計。實驗的過程中白光發光二極體模組的製造程序如下，以電子束蒸鍍方式，在氮化鋁板上沉積50奈米的鈦金晶種層，接著以電鍍金增加其金屬層厚度，作為發光源承載基板，接著固晶、封裝、打線、以及批覆螢光粉等步驟完成LED模組。散熱基座的設計是以COMSOL模擬軟體，設計不同結構優化散熱之效果，進而以鋁材質加工實現。對於封裝完成之球泡燈模組進行量測驗證，實驗結果發現在複雜的結構下，分離式綠能LED燈具，在設計的最高工作功率14.4W，頂部最高溫度為77oC，底部為60oC，持續點亮300小時，流明值衰減15%，具有良好的散熱表現。

This research realizes the separation type green energy high power LED bulbs. The lamp module is divided into two parts which are the LED light source as well as the driving circuit. To prevent its thermal interactive effect, the thermal dissipation of main body was individual designed. Compared to the traditional type LED lamps, one part of the new design bulb can be replaced by a new one due to the above two parts have different lifetime. It is the design to reduce the cost and make a best use of the resource. In the experiment, the manufacture of the white LED was described as following. The 50nm-thick Ti/Au seed layer was evaporated on the AlN substrate by the e-beam evaporation. Subsequently, the Au metal layer was electroplated to increase the thickness where the electroplated AlN was as the substrate of the lighting unit. Then die-attach, wire bound, and coating the phosphor were sequent performed to finish the package of the LED module. The design of the heating holder was first simulated by the COMSOL software. Then design different structures and optimize the thermal effect. The realization of the thermal conduction was aluminum material processing. For the complete encapsulating bulb module and measurement verification, the experimental results show that in such complex structure, the separated green LED lamp of our design was powered at 14.4W, the maximum temperature at top bulb was 77oC, and at the bottom of the bulb was 60oC. After continuous light up for 300 hours, luminescence flux was decayed of 15%. It shows the good thermal performance.
