dc.description.abstract隨著近年來的環保意識抬頭與倡導節能省碳的生活方式,也推升了LED在照明上取代傳統光源的應用。本研究是使用原本車燈產品的設計概念,利用光學軟體將現有模型進行最佳化設計,先以單顆LED作為設計基礎,接著以實驗來驗證設計的正確性,結論得到最佳化前後目標值,最大照度值由原本的281 Lux增加到了334 Lux,提高約18%,而相對的總功率則由15.2 lm增加到了19.2 lm,提高約26.3%。最後再採用多顆LED排列結合的方式,並期望在低成本的要求下,使用多顆低單價、低功率的LED,取代單顆高單價、高功率的LED,並且能在符合德規光強度要求的前提下,生產售價較低廉、 省電與高效能的自行車用車燈。zh_TW
dc.description.abstractAs in recent years, the rise of environmental awareness and promote energy-saving and carbon lifestyle, Also driving up on the LED lighting applications replace traditional light sources. The design concept of this research is to use the original lamp products, Use optical software to the existing model for optimal design, Start with a single LED as a basis for designing, Then proceeded to experiment to verify the correctness of the design, Findings before and after optimization target values,Maximum illumination value has increased from the original 281 Lux to 334 Lux,an increase of about 18%, And relative total output by 15.2 lm increased to 19.2 lm, an increase of about 26.3%. Finally LED on the way to arrange the combination, And look forward at the behest of low cost, Using multiple low-price, low-power LED, Replace the single quad-core high-price, high power LED, And in line with Germany regulations subject to the strength requirements, production prices low, power saving and high performance lights for bicyclesen_US
