What does 灯 mean?
灯 (dēng) is the general Chinese word for any electric or oil-burning light source — a lamp, light bulb, ceiling light, streetlight, traffic light, or lantern. The character pictures a fire radical (火) next to 丁, suggesting a small flame. Use 灯 as a stand-alone noun (开灯 'turn on the light,' 关灯 'turn off the light') or in compounds: 台灯 (tái dēng, desk lamp), 路灯 (lù dēng, streetlight), 红绿灯 (hóng lǜ dēng, traffic light), 灯泡 (dēngpào, light bulb), 灯笼 (dēnglong, paper lantern).
Unlike English, where 'light' can also mean illumination as an abstract noun, 灯 refers to the physical object. For light as in brightness or sunlight, use 光 (guāng).
