光(guang)(guang)(guang)纖(xian)照明(ming)是近年來新發展的(de)(de)一門新的(de)(de)高(gao)科(ke)技(ji)裝飾照明(ming)技(ji)術，它(ta)采用光(guang)(guang)(guang)纖(xian)（簡稱光(guang)(guang)(guang)纖(xian)，又稱導光(guang)(guang)(guang)光(guang)(guang)(guang)纖(xian)），利(li)用全(quan)反射原(yuan)理(li)，通過(guo)光(guang)(guang)(guang)纖(xian)將光(guang)(guang)(guang)傳輸到需要人們光(guang)(guang)(guang)的(de)(de)任何地方進行照明(ming)。

有三種類型(xing)的光(guang)(guang)(guang)纖(xian)(xian)(xian):單(dan)股(gu)、多(duo)(duo)股(gu)和(he)網狀(zhuang)。對(dui)于(yu)單(dan)股(gu)光(guang)(guang)(guang)纖(xian)(xian)(xian)，其直徑(jing)為(wei)Ф6~Ф20mm，可(ke)(ke)同時分(fen)為(wei)體(ti)發(fa)光(guang)(guang)(guang)和(he)端(duan)(duan)發(fa)光(guang)(guang)(guang)兩種，對(dui)于(yu)多(duo)(duo)股(gu)光(guang)(guang)(guang)纖(xian)(xian)(xian)，均為(wei)端(duan)(duan)發(fa)光(guang)(guang)(guang)，多(duo)(duo)股(gu)光(guang)(guang)(guang)纖(xian)(xian)(xian)的直徑(jing)一般為(wei)Red0.5?Red3mm，株數多(duo)(duo)達數百根。網狀(zhuang)光(guang)(guang)(guang)纖(xian)(xian)(xian)全部由小直徑(jing)的體(ti)發(fa)光(guang)(guang)(guang)光(guang)(guang)(guang)纖(xian)(xian)(xian)構成(cheng)，可(ke)(ke)以構成(cheng)柔性(xing)光(guang)(guang)(guang)帶。

從理論上講，光是線(xian)性(xing)的，但(dan)實際上人(ren)們(men)(men)希望改(gai)變(bian)光的方(fang)向，科學家(jia)們(men)(men)已經努力了幾(ji)百年，利用鏡頭，鏡子等光學元件，改(gai)變(bian)傳(chuan)播(bo)方(fang)向。光纖(xian)(xian)照明的出(chu)現(xian)，通過以有限(xian)的角度改(gai)變(bian)光的方(fang)向，實現(xian)了光的柔(rou)軟性(xing)傳(chuan)播(bo)次反射后，光線(xian)沿光纖(xian)(xian)路徑(jing)傳(chuan)播(bo)，實現(xian)了柔(rou)性(xing)傳(chuan)播(bo)。但(dan)光纖(xian)(xian)照明的柔(rou)性(xing)傳(chuan)播(bo)并沒有改(gai)變(bian)光線(xian)線(xian)性(xing)傳(chuan)播(bo)的經典理論。
