摘要


LED照明燈具的高發光效率、高可靠性、以及使用壽命長等節能省電,加上可配合環境需求而任意採行多組多重串並聯驅動LED發光的組合優勢,將取代傳統的低壓鹵素燈、白熾鎢絲燈泡及日光燈,成為節能減碳的綠色照明技術主流。 本研究成功地將市售的半周球泡燈利用光學模擬後找出最佳擺放位置,增加整體的出光角度達到165度比一般市售球泡燈增加約45度,一般市售的半周球泡燈大多未標示出光角,但經由實際量測大多約在120至140區間,因此我們從頭自行封裝LED並製作成球泡燈,首先利用光學模擬等光學機制去模擬驗證不但能在實作過程中降低成本外更增加準確性,更進一步設計出立體架構使LED在球泡燈中取得最佳的位置使球泡燈能達到最大出光角。

The Light emitting diodes (LED) possess the advantages of high luminous efficiency, high reliability, long lifetime, low power consumption and energy saving. Furthermore, the LED can be driven in series and parallel mode depend on the environment requirement, these make the LED have a great potential to replace the conventional low pressure halogen lamps, tungsten light bulbs and fluorescence light tubes, and become the mainstream power conservation lighting technology. In this study, we adopted the optical simulation software to analyze the best placement position of the commercial semi-sphere LED lamps. And the total light emission angel could be enhanced up to 165o, which is about 45o larger than that of the commercial LED lamps. Most of the commercial LED lamps didn’t specify the light emission angel, but according to our measurement the values are within 120o~140o range. Thus we packaged the LED lamps into a bulb form and used optical simulation to verify the accuracy, and designed a three-dimensional architecture for LED light bulb packaging for the purpose of obtaining best position and largest light emission angle.
