LG Innotek announced ‘Visible Disinfection Lighting’, which is a functional light source that gives the effect of sterilisation by sunlight with the indoor light. The LED realises the effect of eco-friendly sterilisation, that is, the method used to dry household goods and blankets under the sun, in indoor spaces conveniently and safely at any time.

Bacteria have a characteristic that they become extinct when exposed to sunlight for a long time. It is because of a material called ‘porphyrin’ inside of bacteria which destroys its cells by reacting with certain wavelengths of sunlight. LG Innotek created ‘Visible Disinfection Lighting’ by maximising the use of the 405nm wavelength to which porphyrin reacts most actively, with its unique LED light extraction technology.

Using LG Innotek’s ‘Visible Disinfection Lighting’ one can easily sterilise an indoor space without having to use any chemicals. According to the result of the sterilization power test on Hygienic Light LED by Korea Conformity Laboratories (KCL), 99.9 per cent of escherichia coli get killed.

Especially, since this product does not harm the human body, its sterilisation function can be used with any worries in places where many people pass by such as kitchens or restrooms. The product is verified that it does not have any negative effect on the eyes or skin, from the Photobiological Safety Standard (IEC62471) of International Electrotechnical Commission, an international standard for electrical technology.

Also, ‘Visible Disinfection Lighting’ of LG Innotek can optimise the sterilisation power according to the indoor conditions in the same way as how one controls the brightness of the light.

LG Innotek has already installed this product in the coffin rooms of funeral halls and waste storage rooms in Yonsei University Severance Hospital Seoul as a trial. The product has received positive responses as it enhances the sterilisation effect and gives a psychological relief at the same time.
