Antibacterial LEDs
Print date: 05 December 2024 22:18
Description of the innovative solution
Food hygiene remains a serious public health issue. There is an urgent need for cheaper and safer disinfectant alternatives to ultraviolet (UV) light and chemicals. The innovation proposes to make use of antimicrobial Light-emitting diode (LED) lights whose LEDs utilize light energy with wavelengths ranging from 200 to 780 nm. These can be at work 24/7, delivering continuous protection and creating an inhospitable environment for microbes. LED lights are cheap, easy to use and offer a longer operational life. LEDs produce an antibacterial effect by photodynamic inactivation due to photosensitization of light absorbing compounds in the presence of oxygen and DNA damage.
