等于單位時(shí)間內(nèi)某一波段的輻射能量和該波段的相對(duì)視見(jiàn)率的乘積。由于人眼對(duì)不同波長(zhǎng)光的相對(duì)視見(jiàn)率不同，所以不同波長(zhǎng)光的輻射功率相等時(shí)，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(lái)表示，在理論上其單位相當(dāng)于電學(xué)單位瓦特，因視覺(jué)對(duì)此尚與光色有關(guān)。所以依標(biāo)準(zhǔn)光源及正常視力度量單位采用“流明”，符號(hào)：lm。由于人眼對(duì)不同波長(zhǎng)的光的視見(jiàn)函數(shù)不同，所以不同的波長(zhǎng)的光的輻射功率即使相等，其光通量并不相等。例如當(dāng)波長(zhǎng)為5500的綠光與波長(zhǎng)為6500?的紅光輻射功率相同時(shí)，前者的光通量為后者的10倍。光通量是每單位時(shí)間到達(dá)、離開(kāi)或通過(guò)曲面的光強(qiáng)度；光通量是燈泡發(fā)出亮光的比率。簡(jiǎn)單來(lái)說(shuō)：是衡量光源輸出光多少的指標(biāo)。一個(gè)普通的燈泡，它輸出的所有光全部算在一起后就是這個(gè)燈泡光通量的具體數(shù)值?？梢园阉斫鉃椋阂粋€(gè)噴頭噴出了水，用一個(gè)氣球?qū)姵龅拿恳坏嗡佳b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(hào)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(gè)勒克斯。lx=lm/m^2同樣也可以用水來(lái)作一個(gè)比方：噴頭會(huì)噴很多水出來(lái)。重慶口碑好LED面板燈上海先盛照明電器有限公司為您提供LED，歡迎新老客戶來(lái)電！</p><div
