本論文主要目的在於研究LED的中場行為,並藉由了解光在傳輸時其光場分佈之變化情形,進而定義出準遠場距離。在模擬中,改變LED封裝之型式與封裝之公差,歸納出其對準遠場距離之影響。而本論文中,另一重點為防眩光LED燈具之設計,目的為降低燈具對眼睛之眩光指數。
In the thesis, we study the light pattern variation in the mid-field of an LED. A quasi-far field distance is therefore defined. We change the parameters such as lens geometry, chip size and package error to figure out the effects to the quasi-far field distance. Besides, we design a glare-proof LED lamp with low veiling luminance.
