A new type of ultraviolet lamp

technical field

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

Background technique

Existing ultraviolet lamps use optical filters to filter wavelength bands that are harmful to human body, but this structure still has the defects of small luminous angle and non-single light source, which further reduces the light efficiency of the entire ultraviolet lamp; in addition, the existing ultraviolet lamp Due to the setting of the filter, the volume of the ultraviolet lamp is relatively large. Therefore, we propose a new type of ultraviolet lamp to solve the above-mentioned problems.

Contents of the invention

In view of the shortcomings of the existing ultraviolet lamps in the above background technology, such as small light angle, multiple light sources, and poor light efficiency, the present invention provides a new type of ultraviolet lamp to overcome the defects.

A new type of ultraviolet lamp tube, comprising an outer tube; the inner tube of the outer tube is coaxially provided with an inner tube; the outer tube is embedded with an external electrode; the inside of the inner tube is provided with an inner electrode; the inner electrode The outer surface of the outer cylinder is coated with a clutter coating; the outer wall of the outer cylinder is coated with a single band coating.

As a preferred solution, the single-band coating can only transmit a single-wavelength band to the outside of the outer cylinder.

As a preferred solution, the clutter coating transmits the clutter that cannot be transmitted outside the outer cylinder to the inner electrode and is absorbed by the inner electrode, and at the same time, the clutter coating reflects the available single-wavelength band to the single-band coating Transmitting out the outside of the outer cylinder.

Beneficial effects: the present invention coats the outer surface of the electrode with a clutter coating, and coats the outer wall of the outer cylinder with a single-band coating; filtering is performed in the way of coating, which can ensure the uniformity of light output from the light source, that is, the single-band coating can only The single-wavelength waveband is transmitted from the outside of the outer cylinder to effectively ensure the uniformity of light output from the light source, such as 207nm or 222nm or 250nm or 308nm and other single-wavelength bands, and the clutter coating will transmit all the clutter that cannot be transmitted out of the outer cylinder to the inside electrode, which is absorbed by the inner electrode. Secondly, the volume of the ultraviolet lamp can be greatly reduced by coating, and the ultraviolet lamp can be set in a cylindrical shape to effectively increase the luminous angle of the ultraviolet lamp. At the same time, the clutter The coating reflects the available single-wavelength band to the outside of the outer cylinder through which the single-wavelength coating transmits, effectively improving the light efficiency of the ultraviolet lamp tube.
