Abstract

The utility model discloses a lighting tube which comprises an exposed conduit. The outside of the exposed conduit is compounded with a layer of titanium dioxide film and a layer of silver film, or the outside of the exposed conduit is compounded with a film layer that is formed by mixing titanium dioxide and silver. The lighting tube has the advantages that: when nano Ag-antibacterial material and nano TiO2 photocatalyst are organically combined, under the excitation of a light source or natural light, the continuous and long-term effective performances of disinfection, sterilization and decomposition of organic pollutants can be provided, with the effectiveness higher than a TiO2 photocatalyst lighting tube (the activity of degradation formaldehyde is improved by 5-30 percent in an intermittent photocatalysis evaluation system).
