LED 產業的蓬勃發展，不僅帶動LED 發光效率的快速提升，亦使得LED的使用率普遍至各個家庭。然而，LED 燈高亮度及高指向性之行為相較傳統常用的日光燈與省電燈泡，LED 燈更易造成眩光 （glare） 之問題，這對照明品質上是具有非常重要之影響。長久以來，對於照明品質非常重視，不僅要求空間照度充足，還要空間照度分配均勻，才不會導致眩光及配光均勻度差異太大，造成空間舒適度下降。嚴重的眩光會使得人眼產生視覺疲勞，而無法適應光亮之感覺，更可能引起厭惡、不舒服，喪失明視度。室內照明對於人眼之交互作用來說有直接之影響，無論是在辦公場合、學校教室或居家環境內，燈具所造成的光空間分布與統一眩光指數 （unified glarerating, UGR） 之大小皆會影響到人眼上之感受。論文內容是以測試樣品之燈具類型包含燈泡、燈管、格柵燈及投光燈等室內照明燈具，比較與分析各類型之室內照明燈具之配光曲線圖及統一眩光指數 （unified glare rating, UGR） 之結果，並探討各燈具之間的差異性，其具有實用價值之意義。 |

The rapid development of the LED industry has not only led to a rapidincrease in the efficiency of LED luminance, but has also contributed to theprevalence of LED usage in households. However, due to the highbrightness and high-directivity properties of LED lights compared toconventional fluorescent lights and energy-saving bulbs, LED lights aremore prone to glare, a feature that has a major impact on quality of lighting.Quality of lighting has long been a focus of concern as not only adequate spatial illumination, but also uniform distribution are needed in order toprevent disparities between glare and lighting uniformity, which in turnresults in diminished spatial comfort. Severe glare will cause fatigue ofthe human eye, creating an inability to adapt to light, or even causingdiscomfort and loss of luminance.Indoor lighting has a direct impact on the way the human eye interacts.Whether in an office, a school classroom, or a home environment,lighting-driven spatial distribution and Unified Glare Rating size has animpact on perception of the human eye. The contents of this paperinclude test samples of lighting types, including bulbs, light tubes, grilles,and spotlights, and other indoor lighting. The results of the various typesof indoor lighting, a goinphotometer curve diagram, and the UGR werecompared and analyzed. Additionally, differences between lighting typesand the significance of their practical values were explored. |
