The built-in LED germicidal ultraviolet lamp achievement "the most clean" door handle

Tencent digital news, the door handle is perhaps one of the most "dirty" objects into contact with in our daily life, every day they are many people touch, but often can not get regular cleaning and disinfection. Today, two high school China from the Hongkong Special Administrative Region students aiming at this problem, developed a without the use of chemical irritants, without regular cleaning, through the new door handle built-in ultraviolet lamp to kill bacteria.

The two boy is hit off Simon Huang (Simon Wong) and Michael Lee (Michael Li), they recently in the United States of Pittsburgh Intel international science and Engineering Awards (ISEF) the door handle display uses two kinds of antibacterial Technology: firstly, it made a visible surface with titanium dioxide -- this natural metal oxide itself has anti-bacterial; then, it can emit ultraviolet with a special glass tube, can emit ultraviolet when there is some people use it to open the door, thereby effectively destroying the handle may be attached to the surface of the bacteria DNA, thus blocking their reproduction.

In addition to titanium dioxide antibacterial and ultraviolet sterilization, the door handle and a clever design: it requires no external power supply or install the battery, a built-in transmission device can open closed motion into electricity, so as to provide enough power for the built-in LED lamp.
