COVID-19 and other viruses can live on metal surfaces for upto 72 hours. This makes touchy things like door handles prime transmission points! It is well known that UV-C light can break the chemical DNA bonds in viruses, so why not embed some in door handles? A simple tilt switch will detect the handle has moved and illuminate UV-C LEDs for a set time.
Operation & Design.
A tilt switch detects the handle has moved downwards, and after a few seconds of returning to horizontal - UV-C LEDs are illuminated to destroy the DNA chain in any viruses (eg. COVID-19). A red set of LEDs are also illuminated to show that the disinfecting is taking place. After a user-settable timeout, the UV-C LEDs are extinguished and a set of green LEDs are lit to show the cleaned status. If at any point in the disinfecting stage, the handle is moved the UV-C LEDs are extinguished and the handle remains red until the cleaning process has finished. Designed to be battery operated with a visual status of charge - eg flashing when battery is low. Easy user replacement of batteries is also considered.
