Self-sterilizing door handle by Bomi Choi
We do not pay attention to door handles, except when we want to open the door. I also have never thought about it before. Door handles are always dirty, especially in public places. That's why we need the door handles which sterilize themselves. Bomi Choi solved the problem and won the award Red Dot Design Concept. It's pretty simple and straightforward idea. The design uses ultra violet light. When the door knob untouched, the UV lamp will light up and begin the processes of sterilization. As soon as you try to take it, UV lamp will switch off. UV Ray is a very good and effective means to kill bacteria and germs.
