Subject: Auto LED Lighting-色溫的單位是K
2010-02-05


色溫的單位是K---絕對溫 度是0度K=攝氏-273度C---色溫高顏色偏藍.色溫低顏色偏紅---LED的白光色溫5000~7000K光效較高.稱為正白光色 ---2700~3500K為暖色光.8000~12000K為冷色光---但要注意同值的色溫人眼看的白光會有不同-白光人眼的視敏感度很高---在 CIE1931的光譜圖中色溫的X.Y分布是直豎的線.不是一個點---因每位人的觀點不同白光的色溫不能表示使用者滿意的白光.每位使用者的喜好也有不 同的選擇---但以存效率來看5000~7000K是比較好.
