The door is a passage for people to come in and out.
Opaque hinged doors are widely used in offices,
classrooms and other public facilities.
However, people might bump against each other
in a crowded place when they use the door
at the same time on the opposite direction.
Such accidents frighten or even injure people.
LED light sign of the door can prevent people
from bumping against each other when they
come in and out through an opaque hinged door.
