Lighting Redesign: Added Side-Mounted Recessed Lights to Outdoor Stair Treads

In the attached image of an outdoor grand staircase, remove the overhead lighting and instead embed small recessed light fixtures into the side of each riser, with light sweeping horizontally across the tread of that step. Thus, the horizontal surface of each step should be illuminated by light coming from the side, and the front edge of the tread should cast a clear shadow line on the step below, clearly marking the height difference. From above the staircase, the light-emitting surface should be completely invisible, preventing glare. The retaining walls on both sides of the staircase and the surrounding environment should remain dimly lit, making the entire staircase appear as a series of floating horizontal light bands. Keep unchanged: the staircase's dimensions, number of steps, material, surrounding retaining walls and environment, and camera angle should remain completely fixed. Avoid: retaining any overhead lighting, exposing the light fixtures, eliminating the shadow line of the tread's front edge, or depicting each step with uneven brightness.

依附圖的戶外大階梯,移除由上方投射的照明,改為在每一階立面的側邊嵌入小型埋入式燈具,光橫向掠過該階的踏面。因此每一階的水平面都被由側面來的光照亮,踏面的前緣在下一階上投出一道清楚的陰影線,高低差被明確標示出來。從階梯上方往下看完全看不見發光面,不產生眩光。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。保持不變:階梯的尺寸、階數、材質、周邊擋牆與環境、拍攝視角完全不動。避免:保留由上往下的投光、讓燈具外露、消除踏面前緣的陰影線、把每一階畫成亮度不均。
