Abstract:
Specifically disclosed in the present invention is an ultraviolet lamp tube. The ultraviolet lamp tube comprises an outer tube and an inner tube, wherein the inner tube is arranged inside the outer tube; an outer electrode is arranged on a tube wall of the outer tube; an inner electrode is arranged inside the inner tube; and an outer wall of the outer tube is respectively coated with a coating film A and a coating film B. In the present invention, filtering is performed by means of film coating, such that the oneness of light emitted from a light source can be ensured; the ultraviolet light output power can also be enhanced by means of film coating, thereby improving the photoelectric conversion efficiency; and a light emission angle of the ultraviolet lamp tube can also be effectively increased by means of setting the ratio of the area of a coating film A to the area of a coating film B, thereby effectively improving the light effect of the ultraviolet lamp tube.
