Meeting rooms should be dimmable

A meeting room with adjustable grouped lighting. The ceiling lights are divided into three groups: the side near the screen can be turned off independently for clear projection, the group above the table maintains a medium brightness so people can see each other and their notes, and the peripheral wall wash lights provide ambient brightness. The image shows the state during a presentation: the screen side is dark, the tabletop has soft light, and faces are clearly visible. Avoid: only having two states (all on/all off), turning the entire room completely dark during projection so people are invisible, using single-circuit lighting, having reflections of light fixtures on the screen.

一間照明分組可調的會議室。天花的燈分成三組:靠螢幕那一側可以單獨關掉讓投影清楚、桌子上方的一組保持中等亮度讓人看得到彼此與筆記、周邊的洗牆光提供環境亮度。畫面裡是簡報中的狀態:螢幕側是暗的,桌面有柔和的光,人臉看得清楚。避免:只有全開與全關兩種狀態、投影時把整間關到全黑看不到人、使用單一迴路的照明、讓螢幕上有燈具的反光。
