名詞解釋 - 照度
資料來源：維基百科
照度的單位：勒克斯(lux)

照度(Illuminance)是每單位面積所接收到的光通量。照度的大小取決於光源的發光強度，及被照體和光源之間的距離。對於同樣光源而言，當光源的距離為原先的兩倍時，照度減為原先的四分之一，呈平方反比關係。

SI制單位是勒克斯（lx=lux）或輻透（ph=phot），1勒克斯=1流明/平方米，1 輻透 = 1流明/平方厘米，1 輻透 = 10000勒克斯。
居家的一般照度建議在300~500勒克斯之間。

物理量 英文 符號 計量單位 單位符號 註釋
光通量 Luminous flux Φv 流明 lm（lm= cd·sr） 單位時間內由光源所發出或由被照物所吸收的總光能。
光強度(發光強度) Luminous intensity Iv 坎德拉(燭光) cd（cd= lm/sr） 光源在給定方向上，每單位立體角內所發出的光通量。
輝度(亮度) Luminance Lv 坎德拉每平方米 cd/m2 單位面積光源在給定方向上，在每單位面積內所發出的總光通量。其單位有時也稱尼特（nit）。
光能(光視效能) Luminous energy Qv 流明·秒 lm·s 單位有時被稱作"talbot"。
照度 Illuminance Ev 勒克斯 lx（lx= lm/m2= cd·sr/m2） 物體表面每單位面積所吸收可見光的光通量，用於入射表面的光。
光出射度 Luminous exitance Mv 勒克斯 lx（lx= lm/m2= cd·sr/m2） 物體表面每單位面積所發出可見光的光通量，用於出射表面的光。
曝光量 luminous exposure Hv 勒克斯·秒 lx·s 也稱作photometric exposure。
發光效率/光效 Luminous efficacy η 流明每瓦特 lm/W= cd·sr/W 通常指光源光通量與光源輸入電功率的比值，有時也指光通量與幅射通量的比值。
光源能量利用率 luminous efficiency V 純數量 無單位 光源幅射通量與光源輸入電功率的比值。
