Abstract:	本?文奠基於孫慶成教授所?導之固態照明實驗室之光學設計與封裝技術，設計一發光二極體陣列光源，並將其應用於自行車車頭燈之遠近燈設計中，其表現可通過嚴謹的德國自行車車頭燈法規。為了能將遠近燈設計於一個反射杯內，遠燈與近燈之光源在相對位置上需要有很大的空間自由度，但反觀大部分市售LED皆因其固有的封裝大小，使得我們在車頭燈設計上的自由度大幅減少。而本論文提出之發光二極體陣列將30個(20 mil×20 mil)大小的晶片封裝於一高導熱類鑽碳鋁基板上，此光源不只為遠近燈的設計上提供了極高的自由度，也可以利用點亮不同位置的晶片來產生不同的光型以滿足不同的需求或法規。;This thesis is based on the optical design and packaging technology of the solid-state lighting laboratory led by Professor C. C. Sun. We design a LED array light source and apply it to the design of the low and high beams of bicycle headlights. The performance can pass the strict regulations issued by German Bicycle headlight regulations. We expect that the low beam and the high beam can be designed into a reflector, and they need to have a lot of space flexibilities in the relative position. But in contrast, most of the LEDs on the market, due to their inherent package size, greatly reduces flexibility of design in headlights. The LED array proposed in this thesis encapsulates 30 chips on one DLC-MCPCB. This light source not only provides a high flexibility in the design of the low and high beam, but also can light up the chips in different positions to yield a variety of light shapes to fit customized requirements or regulations.
