Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet lamps, in particular to a U-shaped ultraviolet lamp. Background Art

[0002] An ultraviolet lamp is a device that can emit ultraviolet rays, usually referred to as a UV lamp. It is a lamp that uses low-pressure mercury vapor to be excited to emit ultraviolet rays for irradiation.

[0003] U-type ultraviolet lamp (also known as U-type UV lamp) is a specially designed ultraviolet light source, which is shaped like the letter "U". This lamp tube is usually made of quartz or glass and is filled with ultraviolet gas, such as mercury vapor. When current passes through the lamp tube, the mercury vapor emits ultraviolet radiation.

[0004] The main feature of the U-shaped UV lamp is its U-shaped design, which enables the light source to provide more uniform UV radiation in a smaller space. This design makes the U-shaped UV lamp very effective when a specific irradiation mode is required or when used in a limited space. It is generally used for sterilization, curing, detection, water treatment, and photochemical reactions.

[0005] However, the U-shaped ultraviolet lamp is usually connected to the lamp holder by screws. When it needs to be maintained and cleaned, special tools are needed to remove the screws, which has a slow working efficiency. In addition, the screws will rust after long-term use, which is not conducive to the removal and installation of the screws. Utility Model Content
