本論文之目的在於以高功率白光LED為光源，設計高安全性之自行車前燈。我們以歐洲法規為設計考量，並加強照明區域之寬廣度與近距離之路照，來設計兩款自行車前燈。第一款為微型化之自行車前燈，目的為設計出機構尺寸微小的自行車前燈。第二款為高對比之自行車前燈，我們先設計一能形成高對比度光形的高容忍度光學結構，並以此結構設計高公差容忍度之高對比自行車前燈。In this thesis, we present two bicycle head lamp designs that satisfy the European regulations using high-power white-light LEDs. The first one is a mini-size headlamp design, which not only meets the regulations, but also has small dimensions. The second headlamp design is a high tolerance optical structure with high contrast in light pattern. Using the high tolerance optical structure, we finished a bicycle head lamp design finally. This bicycle head lamp had the advantages of high tolerance and high contrast.
