高效能LED頭燈研製

本論文主要是研究RGB LED頭燈控制系統，其在白天時可直接地做為晝行燈之應用，而天色昏暗不佳時可直接提升RGB LED亮度成為大燈照射，可省去開啟頭燈之動作又可兼具晝行燈功能。此功能可有效減少頭燈系統之燈具安裝數量與降低車輛電力系統耗損，並進一步提升駕駛者和路人之辨識能力與操作便利性。首先本論文在實驗中，使用高功率RGB LED燈模組。我們並自製定電流可調光電路，主要控制RGB LED電流大小以達到控制色溫之目的。並利用數位訊號控制器來做為判斷輸入訊號控制之核心。最後證明此創新設計控制理論之可行性。

This theory is mainly discussing the idea turn on the headlight system of RGB LED. In the daytime, it can be used as the D.R.L (Daytime Running Light) and also it can increase the brightness of the headlight reflection during the nighttime, and eliminating the need to turn on the headlights of action can be both D.R.L function. This application has obviously reduced the quantity of light module and decreased of the vehicle electric power. Moreover, it can upgrade the identification and operation of the drivers and pedestrians. In the beginning of this experiment, using the high power RGB LED light module and we homemade constant current circuit can control the RGB LED current size in order to stable the color temperature. By using the digital signal controller to determine the core of input signals, we can prove the result of the possibility of this new creativity designing.
