Illuminance Below 100 Lux

A space dark enough to just barely make out a person's face. The overall illuminance is kept below one hundred lux, with most areas even lower; the light is not uniform but rather several separate pools: a narrow beam of light on the bar countertop, linear light under the wine cabinet shelves, and a candle or a low wall lamp at each table. There are no lights on the ceiling at all. People's faces are softly illuminated from below by the light on the tables. Avoid: installing recessed lights and track lights on the ceiling, using uniform ambient lighting, increasing the illuminance to a level where fine print can be read, using cool white light.

一個暗到剛好能看清楚人臉的空間。整體照度壓在一百勒克斯以下,大部分區域更低;光不是均勻的而是幾個分離的池:吧台工作面上的一道窄光、背酒櫃層板下的線性光、每一桌一支蠟燭或一盞矮壁燈。天花上完全沒有燈。人的臉被桌上的光由下往上柔和地照亮。避免:在天花安裝嵌燈與軌道燈、使用均勻的環境照明、把照度提高到可以閱讀細字、使用冷白光。
