Definition
冷光 has two distinct senses. In physics, it refers to 'cold light' — light produced by a chemical or biological process (like glow sticks or fireflies) that generates little to no heat. In figurative usage, it describes a cold, stern, or intimidating look in someone's eyes — a gaze that feels emotionally distant or hostile.
