Zhàomíng literally combines zhào (to shine, illuminate) and míng (bright, light), together meaning 'lighting' — the provision or arrangement of light in a space. It refers to artificial light sources and systems used for visibility, safety, or ambiance, not natural light like sunlight.

This noun is commonly used in architectural, engineering, and everyday contexts — for example, when discussing building design, energy efficiency, or home renovation. It often appears in compound terms like 照明系统 (lighting system) or 照明设备 (lighting fixtures). Unlike the verb 照亮 (to illuminate something), zhàomíng is strictly a noun and never used as a verb. It carries a neutral, technical tone and is appropriate in both formal reports and casual conversation about lights in rooms, streets, or workplaces.
