Clinic Medical Lighting: The Dilemma of Color Rendering and Comfort

A consultation room with two coexisting lighting systems. Examination area: high illuminance, high color rendering neutral white light, concentrated on the examination table. The doctor needs to accurately interpret skin color, wound condition, and blood color. The light source has accurate color rendering, no color cast, and sufficient brightness. Waiting and discussion area: low illuminance warm white light, from indirect wall light and a floor lamp. The brightness is soft, and the walls are warm wood tones, making patients feel unscrutinized while waiting and explaining their condition. The two areas are clearly distinguished by brightness and color temperature within the same space, with a transition zone. Large cold white flat panel lights are not used on the ceiling. Avoid: using high illuminance cold white light throughout the entire room, insufficient color rendering in the examination area, illuminating the waiting area to medical-grade brightness, using colored mood lighting.

一間診間,照明分成兩套並存。診療區:高照度、高演色性的中性白光,集中在診療檯上,醫師需要正確判讀皮膚的顏色、傷口的狀態與血色,光源顯色準確、無色偏、亮度充足。等候與談話區:低照度的暖白光,來自牆面的間接光與一盞立燈,亮度柔和,牆面是溫暖的木色,讓病人在等待與說明病情時不會感到被審視。兩個區域在同一空間內以亮度與色溫明確區分,中間有過渡。天花不使用大片的冷白平板燈。避免:整間都用高照度冷白光、讓診療區演色性不足、把等候區也打成醫療級亮度、使用彩色氣氛燈。
