LG Innotek Introduces ‘Visible Disinfection Lighting’

It has been widely reported that LG Innotek this week announced its ‘Visible Disinfection Lighting’, which is a functional light source that gives the effect of sterilization by sunlight but uses indoor light.

The LED has the same effect of eco-friendly sterilization, that is, the method used to dry household goods and blankets in the sun, but can be used in indoor spaces conveniently and safely, and at any time.

Some bacteria die 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 maximizing the use of the 405nm wavelength to which porphyrin reacts most actively.

Using LG Innotek’s ‘Visible Disinfection Lighting’ one can easily sterilize 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% of escherichia coli were killed.

Especially, since this product does not harm the human body, its sterilization function can be used without any additional concerns throughout kitchens or restrooms. The product has been 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.

Song June-O, the Vice President of LED Business Unit, said, “The ‘Visible Disinfection Lighting’ is an innovative solution that will brighten up our living space and at the same time sterilize it safely and conveniently. It will be able to improve the quality of many people’s lives.”
