Ultraviolet Lamp for Suppressing Bad Odor (China)
A Chinese University has developed an ultraviolet lamp that decomposes stink odor. The ultraviolet lamp releases electric charges under a microwave of 2.45GHz, producing an ultraviolet light of 200 nm wavelength that decomposes stink odors. Decomposition experiments on carbon disulfide and hydrogen sulfide have shown that the ultraviolet lamp has enhanced the decomposition rate by 50%, compared with traditional methods. Based on the findings, researchers proposed to decompose stink odors using dual-plasma medium, and have achieved better results. The electrode free ultraviolet lamp has an illumination of 200 watts or more, much more powerful than the ultraviolet lamps sold in the market for disinfection purpose.
