Title:
NOVEL ULTRAVIOLET LAMP
Document Type and Number:
WIPO Patent Application WO/2022/267630
Kind Code:
A1
Abstract:
Specifically disclosed is a novel ultraviolet lamp, which comprises an outer cylinder. An inner cylinder is coaxially arranged inside the outer cylinder. An outer electrode is embedded in the outer cylinder. An inner electrode is provided inside the inner cylinder. A clutter coating is plated on the outer surface of the inner electrode. A single-waveband coating is plated on the outer sidewall of the outer cylinder. In the present invention, a clutter coating is plated on the outer surface of an electrode and a single-waveband coating is plated on the outer sidewall of the outer cylinder. The uniformity of light output of a light source can be ensured by means of using coatings, and the size of the ultraviolet lamp can be greatly reduced by means of coatings while the ultraviolet lamp can be configured into a cylindrical shape to effectively enlarge the light-emitting angle of the ultraviolet lamp, thereby effectively enhancing the light efficiency of the ultraviolet lamp.
