LG Innotek wants its violet LEDs indoors for disinfection luminaires
The company says the 405nm light can achieve eco-friendly sterilization indoors, based on the fact that long-term exposure to sunlight makes bacteria unable to reproduce. LG Innotek explains this process is due to a material called ‘porphyrin’ within bacteria which destroys its cells after reacting with certain wavelengths of sunlight, and porphyrin reacts most actively to the 405nm wavelength (violet), the company says. According to LG Innotek, Korea Conformity Laboratories (KCL) confirmed that Hygenic Light LED killed 99.9% of Escherichia Coli (E. Coli) without any chemicals. Added to luminaires, such a violet LED could provide sterilization in kitchens or restrooms, without harming humans. The sterilization power of this so-called ‘Visible Disinfection Lighting’ could be controlled via the light’s brightness.
