UVLampe

A UVLampe is an electrical device that emits ultraviolet radiation for applications such as disinfection, curing, fluorescence, and analytical instrumentation. Ultraviolet light spans roughly 100 to 400 nanometers and is commonly categorized as UV-A (315–400 nm), UV-B (280–315 nm), and UV-C (100–280 nm). UVLampe designs usually target a specific band, with UV-C lamps favored for germicidal use.

Technology and types: Traditional UV lamps use mercury vapor in a tube. Low-pressure lamps emit a strong line near 254 nm, suitable for disinfection; medium-pressure lamps deliver a broader spectrum. Amalgam lamps increase output, and UV-C LEDs provide compact, mercury-free sources with improving efficiency.

Applications: UV-C lamps purify water and air, disinfect surfaces, and sterilize medical instruments. They are also used to cure UV-sensitive inks and resins, in forensic analysis, and for certain horticultural lighting. The choice of lamp depends on the target wavelength, required dose, and exposure time.

Safety and disposal: UV radiation can cause skin burns and eye injuries; direct exposure should be avoided, and shielding or protective equipment used. Many lamps include interlocks and ozone-suppression features. Mercury-containing lamps require proper disposal; LED-based UV sources avoid mercury but still demand responsible end-of-life handling. Regulations typically cover photobiological safety, electrical safety, and environmental compliance.
