什么是通量

在照明行业中,光通量特指光通量或光通量。它是一个基本概念,用于测量光源在单位时间内发出的可见光总量。光通量通常以流明(lm)来量化,流明是一种测量单位,代表人眼能感知到的可见光量。

光通量在评估光源的性能和效率方面起着至关重要的作用。它考虑到了人眼对不同波长光的敏感度,可以更准确地反映出感知亮度。这意味着,不同光谱分布的光源如果产生等量的可见光,则光通量可以相同。

光通量 是照明设计中的一个重要参数。它有助于确定特定应用所需的适当光量,确保最佳照明水平。此外,光通量还可用于计算光照度。 發光效能光源测量其将电能转化为可见光的效率。

常見問題

更高的瓦特数是否意味着更亮的光

一个标准的 40 瓦灯泡能产生约 400 流明的亮度。一般来说,瓦数越高,流明越高,发出的光量也越大。

流明是多少勒克斯

当流明散布在一平方米的面积上时,一流明相当于一勒克斯。

光通量越高越好吗

消费者通常会比较各种灯泡的光通量,因为它可以显示灯泡发出的光量。就效率而言,光通量与消耗功率比越高的灯泡效率越高。
