Nighttime Light Pollution: Animals Sleep Earlier Than Humans

A green space with almost no lighting at night. Only main paths have low ground lights, less than sixty centimeters high, with light directed completely downwards, equipped with glare shields, and a color temperature below 2200K, appearing amber. Water bodies, forested areas, and grasslands have no lights at all, being truly dark. People can see the path beneath their feet, and look up to see tree silhouettes and the sky.
Avoid: Using high-pole floodlights to illuminate the entire green space, using cool white light and blue light, installing landscape spotlights on waterfronts and trees, extending the lighting range into forested areas and water bodies.

一處夜間幾乎不打燈的綠地。只有主要步道有低矮的地燈,高度不到六十公分,光完全向下、有遮光罩、色溫在二千二百K以下呈現琥珀色;水域、林區與草生地完全沒有燈,是真正的黑。人可以看到腳下的路,抬頭則看得到樹的剪影與天空。避免:使用高桿投光燈照亮整片綠地、使用冷白光與藍光、在水岸與樹上設置景觀投射燈、讓照明的範圍延伸進林區與水體。
