"Light reflects off mirror" in Chinese Light reflects off mirror.


镜子反射光 or 光反射镜子, which is correct?

镜子反射光 is supporsed to be right. But it sounds strangely for me. How do you think about it?
When light, heat, or other rays reflect off a surface or when a
  surface reflects them, they are sent back FROM the surface and do not
  pass through it.


“Light reflects off mirror.” means 光线从镜子反射出来/过来/回来/开来. "Off" denotes the sense of 'from' in this case. 

Compared to this sentence:


  The sun reflected off the snow-covered mountains. // 阳光从被雪覆盖的山峦反射回来。


As a sidenote, from English perspective, maybe it's better to put: 


  Light reflects off mirrors. Or, Light reflects off the/that mirror.


But I am not a native English speaker. It's all opinion-based. Hope some English native speakers can correct me if I'm wrong. Thanks!
