UV Lamp Tube: Diameter 15mm-25mm, Arc Length 100mm-2000mm

Component Specifications

Definition

A UV lamp tube is an artificial light source that emits ultraviolet radiation within specific wavelength ranges (typically UVA 315-400nm, UVB 280-315nm, or UVC 100-280nm). It consists of a sealed quartz or glass envelope containing mercury vapor or other excimer gases, electrodes, and internal coatings that determine the spectral output. These tubes convert electrical energy into UV radiation through gas discharge principles and are essential components in industrial UV curing systems, water/air purification, and surface modification equipment.

Working Principle

UV lamp tubes operate on the principle of gas discharge. When high voltage is applied across the electrodes, it ionizes the mercury vapor or excimer gas inside the tube, creating plasma that emits ultraviolet radiation. The specific wavelength output depends on the gas mixture, pressure, and phosphor coatings. The UV radiation then initiates photochemical reactions in target materials (such as polymerization in UV-curable inks/coatings or DNA disruption in microorganisms).

Materials

Quartz glass envelope (high-purity fused silica for UVC transmission), tungsten electrodes with thorium oxide coating, mercury amalgam or metal halide fill, molybdenum foil seals, internal phosphor coatings (for specific wavelength conversion), nickel-plated brass or ceramic end caps.

Frequently Asked Questions

What is the difference between UVA, UVB and UVC lamp tubes?

UVA tubes (315-400nm) are primarily used for curing and polymerization applications. UVB tubes (280-315nm) are used for specialized curing and medical applications. UVC tubes (100-280nm) are used for disinfection and sterilization due to their germicidal properties.

How often should UV lamp tubes be replaced?

Replacement intervals depend on usage hours and intensity degradation. Most industrial UV tubes require replacement after 1000-8000 hours of operation or when UV output drops below 70% of initial intensity, typically measured with radiometers.

Can UV lamp tubes be disposed of as regular waste?

No. UV tubes contain mercury and must be disposed of according to local hazardous waste regulations. Many manufacturers offer take-back programs for proper recycling and disposal.
