Recessed Stair Lights: Revealing the Height Difference of Each Step

Night view of a large outdoor staircase. Small recessed luminaires are embedded in the side of the riser (kick plate) of each step, with light sweeping horizontally across the tread of that step. Thus, the horizontal surface of each step is illuminated by a side-coming light, and the front edge of the tread casts a clear shadow line on the next step, clearly marking the height difference at night and preventing misjudgment. The luminaires are embedded in the side wall and are completely invisible from above the staircase. The retaining walls on both sides of the staircase and the surrounding environment maintain low brightness, making the entire staircase appear as a series of floating horizontal light strips. The color temperature is warm white. Avoid: overhead lighting that illuminates the entire staircase, exposed luminaires causing glare, eliminating the shadow of the tread's front edge, depicting each step with uneven brightness.

戶外大階梯的夜景,每一階的立面(踢面)側邊嵌著小型的埋入式燈具,光橫向掠過該階的踏面。因此每一階的水平面都被一道由側面來的光照亮,而踏面的前緣在下一階上投出一道清楚的陰影線,高低差在夜裡被明確標示出來,不會誤判。燈具埋在牆側,從階梯上方往下看完全看不見發光面。階梯兩側的擋牆與周邊環境維持低亮度,整組階梯像一系列漂浮的水平光帶。色溫暖白。避免:從上方投光把整座階梯打亮、讓燈具外露造成眩光、消除踏面前緣的陰影、把每一階畫成亮度不均。
