Linear Light Hidden in Grooves

A linear light hidden in an architectural recess. At the junction of the wall and ceiling, there is a recessed groove five centimeters wide and ten centimeters deep. The light strip is installed on the inner side of the groove, facing upwards, and the light washes over the curved ceiling before diffusing downwards. From inside the room, only the illuminated ceiling surface is visible, not the light source or the inside of the groove. This light is continuous around the entire perimeter of the room, without interruption or uneven brightness.
Avoid: exposing the light beads of the light strip, creating individual bright spots of light on the ceiling, interrupting the light trough at corners, using cool white light strips.

一道藏在建築凹槽裡的線性光。牆與天花的交界處有一道寬五公分、深十公分的內凹溝槽,燈帶裝在溝槽的內側朝上,光洗過弧形的天花再漫射下來;從房間裡看只看得到發光的天花面,看不到光源與溝槽的內部。這道光沿著整個房間的周邊連續,沒有中斷與亮暗不均。避免:讓燈帶的位置露出燈珠、讓光在天花上出現一顆一顆的亮點、讓燈槽在轉角處中斷、使用冷白色的燈帶。
