Ellie features sleek and ergonomic designs that make sterilizing baby bottles easy. It also sterilizes the water used for mixing formula to make milk on the go. No more steam, microwave, or boiling bottles, or using toxic chemical wipes on the bottles and pacifiers that go into your baby’s mouth. It is about the size of a lunchbox and fits easily into a diaper bag or mom’s tote bag. Ellie is powered by a USB rechargeable battery and can last more than one week before it needs recharging.
Sterilization using 365 nm UV-LED
UVC is better at breaking molecular bonds as well as rearranging electron configurations, this is how UVC sterilizes, . The longer the substance is exposed to UVC light, the greater the chance that all molecular bonds will have been hit by several high energy photons, causing the molecular bond, from simple weak chemical bonds to stronger ones in simple celled DNA material to be broken, rendering the pathogen/organism inert or dead. Hence the reason sunlight causes skin cancer, and sunblock/sunglasses block light of wavelengths shorter than UVA to protect your eyes and skin, UVA tans well, UVC mostly causes damage, burns, and cancer. Near the limits, at X-Ray to Gamma Ray Sources are used medically to "disrupt" cancerous tumors, with the same interactions mentioned in this post, but at far, far higher energies.
LED sterilizer device can kill up to 99% of bacteria using UV light
The company has already secured a product line-up with products that are optimized for different applications, including 365nm, 385nm, 395nm and 405nm UV-A LEDs for general industry and 305nm UV-B LED for biomedical field as well as 280nm UV-C LED for sterilization.
Do inline LED UV sterilizers exist yet? : Aquariums - Reddit
Great subject. I have a similar use - sterilizing air, killing mould spores in it . I recycled a power supply metal box, installed a special ballast and pair of sockets and a germicidal fluorescent bulb. I also added a six inch fan. All of this was to circulate the air in a trailer we went camping in. Mould builds up in it over the winter and makes a real mess. Dry-Zee-Air balls, light bulb, that sort of thing don't work very well. My little germicidal lamp in a box with a fan work marvellously. My wife noticed that there was grunge on the walls and everywhere in our little trailer and I noticed yesterday that there was no UV output coming from the lamp any more. I have ordered a replacement plus a spare. I have also scoped out the internet for UV leds in the 200 to 300 nm range and haven't found what I was hoping for as suitable replacements. You can buy whole spools of the white ones and stick them to your 4 foot T12 fluorescent tubes and do a conversion over from fluorescent to led lighting in the visible spectrum and that works slick. Nothing in the spectrum I was hoping for. Like many of you I will go back to Google and do a search for that sort of thing periodically. Meanwhile I will keep using the germicidal lights, they last me about 4 years working several months over fall, winter, spring. Then I crack the windows open for air circulation and turn off the UV lights. By the way my germicidal light tube is only about 10" long and takes care of the air in our trailer which is a little over 6 feet wide and about 12 feet long. You'd need more or longer ones for larger trailers.Also the UV LED's in the UV range of sterilizer looked different than normal LED chips that are used in light fixtures as they are enclosed in some type of Brass housing but are not very large but that was also a year ago so don't know if they changed any. Just be sure that if you build one don't look at it without the proper eye protection because I don't think the UV LED in this range emits any light. I was going to use a spectrometer to test if they were on or not and also wear the proper glasses to shield my eyes.
