ECOLOGICAL AND EFFICIENT TECHNOLOGY

UV disinfection devices have already been created with fluorescent lighting technology. These low or medium pressure mercury lamps emit a wavelength of about 254 nm. Mercury lamps have been used f. ex. as disinfection systems in water treatment plants. Adjusting and controlling fluorescent lamps is extremely difficult, and at the end of its working life the fluorescent lamp turns into hazardous waste.UV-LED technology – newer than ever!The UV light produced by LED technology can be adjusted very precisely in terms of intensity, wavelength and ignition and extinguishing. The energy demand for LED technology is remarkably low and the system doesn’t produce so-called AC power at all. LED technology also enables new kind of designing and planning of disinfection products and entirely new applications.UV-LED disinfection is the future of today!

LED Future Oy’s UV-LED technology enables the installation and development of UV-based disinfection systems for a variety of operating environments and applications.

HOW UV TREATMENT
WORKS?

The UVB and UVC light kill the microbes. The ozone layer prevents the UVB and UVC light from entering the ground. For this reason microbes don’t withstand these frequencies of light. Disinfection is based on UVC light that destroys the DNA chains of microbes. Powerful UV-LED lights also destroy the so-called “super bacteria”!

Disinfection treatment with UV-LED technology is a new method with a very wide potential for different applications. The method makes it possible to handle air, various solid surfaces and materials, as well as clear and murky liquids. UV treatment is based on the use of UVA, UVB and UVC light areas when irradiating of the object.

In the exposure unit the subject is illuminated with a suitable UV light wavelength and illumination time to achieve the desired results. UV light works practically against all microorganisms. UV light changes the biological properties of cells by breaking down the structure of the DNA and affecting the different properties of the target organism according to the set values.

Also bacteria resistant to antibiotics respond to UV light, which allows for example the controlling of bacterial epidemics in hospitals with the help of disinfection of indoor air, working spaces and equipment. This can slow down and limit the spreading.

Destruction Of Bacteria

DESTRUCTION OF BACTERIA

The logarithmic reduction of Escherichia coli (cfu/cm2) on the front surface of the mobile device (A=44.5 cm2) due to the impact of the UV Led during 30 minutes. The average impact of the drainage was subtracted from the reductions.              

Figure 1. The impact of the UV-Led treatment on E. coli on the front and back surface of the phone. The maximum logarithmic reduction on the front side 3.3 and on the back side 4.4.

EXAMPLES OF UV-LED DISINFECTION SYSTEM USES

LED Future Oy’s UV-LED technology enables the installation and development of UV-based disinfection systems for a variety of operating environments and applications.

• Disinfecting drinking water efficiently and without chemicals

• Cleaning of swimming pool water without chemicals

• Replacement of pasteurization with UV treatment in dairy products

• Destruction of hospital bacteria with disinfection systems for IV and surgical surfaces

• Ship ballast tanks

• Disinfecting surfaces (for example, washing facilities by swimming pool, hospital equipment or operation rooms, etc.)

• Destruction of indoor air micro-organisms in public and private spaces

• Disinfection of packaging materials in the food industry

• Disinfection of process waters in the food industry

UV Disinfection doesn’t add any chemicals to the disinfection target and doesn’t affect the structure or properties of the disinfection target – except destroying unwanted microorganisms! UV disinfection created with LED technology is highly energy efficient and ecological. Unlike fluorescent technology, LED technology is precisely adjustable, monitored and controlled. LED technology requires little energy and doesn’t cause hazardous waste.
