什么是光敏流明

照度流明是光输出的测量值,它考虑了人眼在强烈照明条件下的敏感度。它用来描述人眼感知到的光量。我们眼睛中的锥状细胞是负责色觉和高强度光感知的感光细胞,在白天或预期光照条件较高时高度活跃。

简单地说,光敏流明表示 光量 我们的眼睛在正常照明条件下所感知到的光线。它是人眼对光能见度的测量,尤其是在光线充足的环境中或白天。该术语用于量化与人类视觉相关的光亮度或强度。

光照流明只是照明设计的一个方面,并不一定代表照明的质量或效果。其他因素如 顯色性, 光分佈在创造最佳照明条件的过程中,光照和视觉舒适度也起着至关重要的作用。

常見問題

多少流明对眼睛有益

低于 3500 流明时,我们的眼睛能感受到舒适的亮度。然而,一旦直射光或反射光的亮度超过 4000 流明,人眼就会开始难以接收光线。

流明是否越高越好

如果您打算在室外或环境光线较强的房间使用设备,高流明数至关重要。这也适用于在宽敞区域使用投影机和/或需要较大屏幕尺寸的情况。

多少流明被认为是非常亮?

对于大多数人行道(包括商业地产)来说,80 流明的亮度通常就足够了。至于用于重点照明的庭院灯,一般 50 流明左右就足够了。这样的亮度有助于提高安全性,增加立体感,引入色彩,并在庭院中营造视觉趣味。
