UVC LED Application Trend: Self-Cleaning Water Bottle

The applications of water disinfection and purification are expanding and becomes a driving force of the UVC LED market. One of the growing applications is UV-C embedded water bottle.

LEDinside reported in August one model of the UV-C LED integrated bottle offered by an on-line design shop NOERDEN. Soon after that, we found more and more similar products launched in the past two months.

In most of the bottles, a UV-C LED module with Li-Polymer battery is equipped with the bottle cap and can be activated to water disinfection by tapping the cap. The caps are mostly water proof and with USB for charging.

Some products have two purification modes, one for low to medium contaminated water which takes about 60 second to diminish up to 99.99% of pathogens and a stronger mode with longer purification time for water sources with medium to high contamination. According to the UV bottle providers, the stronger mode can kill up to 99.9999% of contaminates with two to three minutes satirizing process.

The bottles also provide auto-clean function that turns on autonomously with intervals of every two to four hours for 10 to 20 second cleaning.

LEDinside noted it the latest report that water sterilization is a major drive for UV LED. UV LED makers are aiming to develop home appliances with UV-C LED for static and flowing water disinfection. Compared to flowing water cleaning, the power requirement for LED is lower for static water. UV-C water bottle thus offer an entrance for LED supplier.
