等于單位時間內某一波段的輻射能量和該波段的相對視見率的乘積。由于人眼對不同波長光的相對視見率不同，所以不同波長光的輻射功率相等時，其光通量并不相等。光通量的單位為“流明”。光通量通常用Φ來表示，在理論上其單位相當于電學單位瓦特，因視覺對此尚與光色有關。所以依標準光源及正常視力度量單位采用“流明”，符號：lm。由于人眼對不同波長的光的視見函數不同，所以不同的波長的光的輻射功率即使相等，其光通量并不相等。例如當波長為5500的綠光與波長為6500?的紅光輻射功率相同時，前者的光通量為后者的10倍。光通量是每單位時間到達、離開或通過曲面的光強度；光通量是燈泡發(fā)出亮光的比率。簡單來說：是衡量光源輸出光多少的指標。一個普通的燈泡，它輸出的所有光全部算在一起后就是這個燈泡光通量的具體數值?？梢园阉斫鉃椋阂粋€噴頭噴出了水，用一個氣球將噴出的每一滴水都裝在里面，有多少裝多少，這就是光通量的含義。照度：照度的單位是勒克斯，符號表示為lx。它的定義是落在單位面積上光通量的大小，換而言之，也就是1平方米得到1流明的光叫做1個勒克斯。lx=lm/m^2同樣也可以用水來作一個比方：噴頭會噴很多水出來。</p><p
