Advantages of UV Lamp

Types of UV Lamps

Black Light

This type emits longwave UVA output comprised of small amounts of visible radiation. Fluorescent black lights contain phosphors on their inner tube surfaces, which emit UVA energy instead of visible light. Some employ Wood's glass optical filters to block nearly all wavelengths more than 400 nm. Mercury-vapor mechanisms with envelopes of Wood's glass and a phosphor coating are common in concerts and theatrical productions.

Shortwave

Products of this class comprise fluorescent tubes without phosphor coatings. Approximately 85 to 90 percent of the energy supplied by these lamps occurs at 253.7 nm. Fused-quartz glass tubes allow the passage of 253.7 nm radiation while blocking light occurring at the 185 nm wavelength. The lamps possess two or three times as much power as typical fluorescent units. Analogous germicidal bulbs disinfect surfaces, such as in food processing, laboratory, and water treatment applications.

Gas-Discharge

These contain multiple gasses and produce UV output at precise spectral lines for scientific purposes. Argon and deuterium arc bulbs serve as stable sources. Some lamps, such as magnesium fluoride types, incorporate windows. They operate as sources in UV spectroscopy chemical analysis applications. Excimer lamps have seen recent growing acceptance in scientific usages. The units supply increased intensity and efficiency over numerous wavelength bands in the vacuum ultraviolet.

Ultraviolet LEDs

LEDs operating in the ultraviolet range are deployed in curing applications as well as in digital print activities. Inert curing environments rely on similar elements as well.

Applications of UV Lamps

Forensics
UV sources aid in analyzing evidence in criminal investigations. DNA samples are located using this technology. UV devices also detect counterfeit currency and authenticate artworks and collectibles.

Sanitary Functions
UV elements indicate contaminations on healthcare equipment. It detects organic substances left behind on surfaces when performing general cleaning activities. The hospitality industry relies on handheld lamps for the inspection of bedding to determine when mattress replacement or restoration is necessary, and to monitor the performance of cleaning staff.

Chemistry
Chemical structures are subject to analysis via UV spectroscopy. The light is engaged in biological research to quantify proteins or nucleic acids. They support the analysis of minerals and gems. UV lamps can be used to detect oil sheens on water, as well as sulfur compound and nitrogen oxide emissions.

Curing
Adhesives, polymers, and inks can be quickly cured and made uniform with UV exposure.

Air Purification
Organic-based compounds that contaminate air are destroyed when exposed to intense UV occurring at 240 nm to 280 nm. Gaseous impurities such as carbon monoxide are also reduced through exposure to this radiation.

Disinfection and Sterilization
The items sterilize workspaces as well as tools involved in biological laboratories and healthcare facilities. The devices are employed in disinfection processes for wastewater treatment and water purification. They are involved in food treatment to eradicate microorganisms.

Herpetology
UVB light is required for reptiles to synthesize vitamin D that is vital for metabolizing calcium. Reptiles possess the ability to see UVA wavelengths and fluorescent bulbs are placed in reptile enclosures. The same bulb provides heat for basking.
