Need to know how to say light in Chinese? The word is 灯 (dēng), and you’ll use it every single day in China – from hotel rooms to restaurants to navigating your apartment after dark.
After twelve years in Tianjin, I still remember the night I tried to ask my landlord where the light switch was. I pointed at the ceiling and made vague gestures until she finally said 灯 (dēng) and flipped the switch. That moment taught me that some words are too essential to learn by accident.

Key Takeaways
- 灯 (dēng) means “light” or “lamp” in Chinese – the essential word for anything that illuminates.
- The most useful phrase is 开灯 (kāi dēng) – “turn on the light” – and 关灯 (guān dēng) – “turn off the light.”
- 灯 appears in compound words for traffic lights, flashlights, and street lights – making it one of the most practical words in daily Chinese life.
The Basic Meaning of 灯
The character 灯 (dēng) combines 火 (fire) on the left with 丁 on the right. The fire radical makes perfect sense – lights in ancient China were literally fire-based. Oil lamps, candles, and lanterns all involved flames. Even though we use electricity now, the character keeps its fiery origin.
In modern Chinese, 灯 covers any artificial light source. Ceiling lights, desk lamps, phone screens, car headlights – if it produces light, it’s probably a 灯. This makes the word incredibly versatile for daily conversation.
Common Phrases with 灯
Home Lighting
When you walk into a dark room in your Chinese apartment, you’ll need these phrases immediately:
- 开灯 (kāi dēng) – Turn on the light
- 关灯 (guān dēng) – Turn off the light
- 灯坏了 (dēng huài le) – The light is broken
- 灯太亮了 (dēng tài liàng le) – The light is too bright
I learned 开灯 within my first week in China. My apartment had a complex lighting system with multiple switches controlling different sections of ceiling lights. After several evenings of stumbling in the dark, I finally memorized which switch controlled which 灯.
When dealing with a landlord or repair person, you’ll also need:
- 这个灯不亮了 (zhè gè dēng bù liàng le) – This light isn’t working
- 请换一个灯泡 (qǐng huàn yí gè dēng pào) – Please change the lightbulb
Street Lights and Traffic
Navigating Chinese cities at night means understanding street lighting vocabulary:
- 路灯 (lù dēng) – Street light
- 红绿灯 (hóng lǜ dēng) – Traffic light (literally “red-green light”)
- 黄灯 (huáng dēng) – Yellow light
- 车灯 (chē dēng) – Car headlights
The word 红绿灯 is particularly important. Chinese traffic lights follow the same red-yellow-green pattern as most countries, but the timing and local driving habits can surprise newcomers. Knowing how to say “traffic light” in Chinese helps when giving directions or asking about routes.
You’ll also see decorative lanterns during festivals:
- 灯笼 (dēng long) – Lantern (traditional red Chinese lantern)
- 孔明灯 (kǒng míng dēng) – Sky lantern
Electronic Screens and Devices
Modern life adds new meanings to 灯:
- 闪光灯 (shǎn guāng dēng) – Flash (camera)
- 指示灯 (zhǐ shì dēng) – Indicator light
- 台灯 (tái dēng) – Desk lamp
- 床头灯 (chuáng tóu dēng) – Bedside lamp
When your phone battery is dying and you need to ask someone for a charger, you might mention that your screen 灯灭了 (dēng miè le) – the light went out.
Related Words
Understanding 灯 means also knowing these related words:
- 亮 (liàng) – Bright, illuminated
- 暗 (àn) – Dark, dim
- 黑 (hēi) – Black, dark (color)
- 明 (míng) – Bright, clear
The contrast between 亮 and 暗 appears constantly in daily life. Your hotel room might be too 亮 (bright) at night, or the hallway might be too 暗 (dark). These descriptive words pair naturally with 灯.
Cultural Notes
In Chinese culture, light carries symbolic weight beyond its practical function. During Chinese New Year, red 灯笼 (lanterns) represent prosperity and good fortune. The Lantern Festival (元宵节) marks the end of New Year celebrations with elaborate light displays.
When visiting someone’s home, you might notice they keep certain lights on for good luck or feng shui reasons. Understanding that 灯 has both practical and cultural dimensions helps you navigate social situations more smoothly.
Electricity vocabulary extends beyond 灯 to include air conditioning, washing machines, and other household appliances. But 灯 remains the word you’ll use most often when discussing your living space.
