LED Light Disinfects Its Environment

LG Innotek unveils what it’s calling 'Visible Disinfection Lighting', a functional LED light source that gives the effect of sterilization by sunlight with the indoor light.  The LED realizes the effect of eco-friendly sterilization, i.e., the method used to dry household goods and blankets under the sun, in indoor spaces at any time.


Bacteria become extinct when exposed to sunlight for a long time due to a material called 'porphyrin' inside of bacteria that destroys its cells by reacting with certain wavelengths of sunlight. The company’s solution maximizes the use of a 405-nm wavelength, which porphyrin reacts to.
