Perguntas frequentes
10 perguntasYou can use 发光 to describe something that literally gives off light. For example, 星星在发光 (xīngxīng zài fāguāng) means 'The stars are glowing.'
Generally, 发光 is for literal light emission. If you want to talk about someone 'shining' in a metaphorical sense, like being brilliant or outstanding, you'd use other words such as 闪耀 (shǎnyào) or 出众 (chūzhòng).
发光 (fāguāng) means 'to emit light' or 'to glow', focusing on the act of producing light. 亮 (liàng) can mean 'bright' (adjective) or 'to light up' (verb). For example, 灯亮了 (dēng liàng le) means 'The light turned on/is bright', while 灯在发光 (dēng zài fāguāng) means 'The light is emitting light/glowing'.
Yes, 发光 is a very common and practical word, especially when describing natural phenomena or man-made objects that produce light.
No, 发光 implies emitting light itself. For something that reflects light, you'd typically use words like 反光 (fǎnguāng) meaning 'to reflect light'.
While its primary meaning is literal, sometimes you might hear it in a slightly figurative way, like someone's eyes '发光' (fāguāng) when they are excited or inspired. But its main use is for literal light.

发光 itself is primarily a verb. If you want to talk about 'glow' as a noun, you might say 光芒 (guāngmáng - radiance) or 光泽 (guāngzé - luster), depending on the context, but 发光 describes the action.
While fluorescent lights 发光, you'd usually refer to the type of light itself as 荧光灯 (yíngguāngdēng - fluorescent lamp). You could say 荧光灯在发光 (yíngguāngdēng zài fāguāng - The fluorescent lamp is glowing).
Sure. 在黑暗中，远处的小屋窗户透出微弱的光，仿佛在发光 (Zài hēi'àn zhōng, yuǎn chù de xiǎowū chuānghù tòuchū wēiruò de guāng, fǎngfú zài fāguāng). This means 'In the darkness, the window of the distant cabin emitted a faint light, as if it were glowing.'
