Description

Novel ultraviolet lamp tube

Technical Field

The invention relates to the technical field of ultraviolet lamps, in particular to a novel ultraviolet lamp tube.

Background

The existing ultraviolet lamp tube utilizes the optical filter to filter the wave band with wavelength harmful to human body, but the structure still has the defects of small light-emitting angle and not single light source, thereby reducing the light efficiency of the whole ultraviolet lamp; in addition, the existing ultraviolet lamp tube has larger volume due to the arrangement of the optical filter. Therefore, we propose a new ultraviolet lamp tube to solve the above problems.

Disclosure of Invention

Aiming at the defects of small light-emitting angle, non-single light source and poor light effect of the existing ultraviolet lamp in the background technology, the invention provides a novel ultraviolet lamp tube for overcoming the defects.

A novel ultraviolet lamp tube comprises an outer tube; an inner cylinder is coaxially arranged inside the outer cylinder; an outer electrode is embedded on the outer cylinder; an inner electrode is arranged inside the inner cylinder; the outer surface of the inner electrode is plated with a clutter coating film; the outer side wall of the outer barrel is plated with a single-waveband coating film.

Preferably, the single-wavelength-band coating film can only transmit a single wavelength band outside the outer tube.

Preferably, the clutter coating transmits the clutter which cannot be transmitted out of the outer cylinder to the inner electrode and is absorbed by the inner electrode, and the clutter coating reflects the usable single-wavelength waveband to the single-waveband coating and transmits out of the outer cylinder.

Has the advantages that: the clutter coating film is plated on the outer surface of the electrode, and the single-waveband coating film is plated on the outer side wall of the outer cylinder; the filtering is carried out by adopting a film coating mode, so that the light emitting unicity of a light source can be ensured, namely, the single-wavelength film coating can only transmit a single-wavelength band out of the outer barrel, so that the light emitting unicity of the light source is effectively ensured, for example, the single-wavelength band with the wavelength of 207nm, 222nm, 250nm, 308nm and the like, noise waves which cannot transmit out of the outer barrel are transmitted to the inner electrode by the noise wave film coating and are absorbed by the inner electrode, secondly, the volume of the ultraviolet lamp tube can be greatly reduced by adopting the film coating mode, meanwhile, the light emitting angle of the ultraviolet lamp tube can be effectively increased by arranging the ultraviolet lamp tube into a barrel shape, and meanwhile, the available single-wavelength band is reflected to the single-wavelength film coating out of the outer barrel by the noise wave film coating, so that the light emitting efficiency of the ultraviolet lamp tube is effectively improved.
