中文摘要:

國際固態照明技術最新發展重點之一為LED 光引擎，光引擎的標準化、高效率、低成本、光品質及智慧化為目前主要開發方向，台灣目前仍處於起步階段，LED積體化光引擎主要透過高度整合光、機、電、熱、控關鍵技術，發展高性價比，體積小，長壽命及智慧化的標準光源，本研究為發展系統封裝在基板的製程，將LED晶片、一次光學封裝、直流積體化電源驅動及控制電路(電控IC)整合於高導熱石墨金屬複合基板上, 搭配模組化設計二次光學反射杯及散熱器，組成LED積體化光引擎。透過關鍵技術整合將直流光引擎效率提升至大於80lm/W，未來目標為200lm/W交流積體化光引擎，透過電控IC將使光引擎內含之燈具具有智慧化控制功能，光源體積小的特色可應用於燈具多樣化設計，透過積體化將使光引擎更容易推廣至智慧照明的應用領域。

High performance LED integrated light engine

Abstract:

           Solid state lighting technology focuses on the standardization and performance improvement with LED light engine. Taiwan currently is making initial progress to integrate photonic, mechanical, thermal and controlling key technologies aspects making smaller, higher cost-performance, longer-life and smarter standard light engine. In this study, We integrate the LED driving circuit in the silicon chip, GaN based blue chip, phosphor and electrical component on Al-graphite composite substrate. Through the system in package technologies can bring DC light engine efficiency to more than 101 lm / W@7047K (DC at 9.38V); in the future the target will be at 200 lm / W. The optical and electrical performance will be presented. The lamp with the light engine will have the intelligent control function and can be easily expanded to the field of smart lighting.
