This technology utilizes a 450 nm wavelength light-emitting diode (LED) combined with a surface plasmon structure. The LED light induces surface plasmon excitation that promote the ionization of water molecules in the air. These ionized molecules effectively decompose harmful airborne substances. The system can be applied to animal health management. It improves air quality, helps reduce carbon emissions, and supports the development of a more sustainable and animal-friendly farming environment.

This technology integrates a 450 nm LED with a surface plasmon structure to ionize airborne water molecules and breaking down harmful substances. It extends beyond traditional LED use, enabling sterilization, mold removal, and methane degradation. Field tests in livestock farms and meat markets show improved air quality and reduced PRRSV levels. With potential applications in smart farming and food environments, it supports energy saving, carbon reduction, and animal health improvement.

This technology is applied for active purification of PM2.5, viruses, bacteria, and harmful gases without chemicals. Proven effective in livestock farms and meat retail settings, it improves air quality, controls pathogens, and extends meat shelf life. With smart monitoring and environmental control, it aligns with net-zero and ESG goals. Highly commercializable, it offers scalable applications across the livestock and food industries, supporting sustainability and industry advancement.
