PRIVACY PROTECTOR
These days It’s important to protect each person’s privacy.
So sometimes if other people suddenly got into our private space, it would be very unpleasant.
This design describes a light built-in doorknob which has two kinds of light color that visitors can notice and classify by intuition
whether the hosts of certain spaces(room,classroom,anywhere has a door) allow somebody come in or not.
(for example, green and red. Green light sign indicates entrance allowed, and the Red one indicates enterance prohibited)
