Ultraviolet (UV) LEDs are unique lamps that emit light within a range of 10 nm and 400 nm. At this rate, the bands are invisible and undetectable without special machines.
These days, there are plenty of uses for UV LEDs in industrial operations. For example, in commercial paint spray booths, explosion proof UV lamps are crucial components for paint curing. The lights help streamline the final stages of curing, for a speedy, thorough finish of coatings.

Top 5 UV LED Applications:
- Food/Air (HVAC) Sanitation: UV LED lamps that emit UV-C bands are capable of non-invasive disinfection. Food manufacturing plants use such lighting systems to clean vegetables and other products before packaging. Interestingly, UV luminaries can also be installed inside HVAC systems, elevators and vents to promote clear airflow.
- Currency Verification: Law enforcement groups use handheld UV lights to verify the legitimacy of banknotes. Exposure to UV bands cause certain components inside bills, such as embedded stripes, to glow or turn different colors. Such techniques are also applicable to artwork inspection. Curators may shine UV light over paintings to check for inconsistencies, repairs and hidden elements (overpainting or the use of new inks).
- Mineral Detection: In mining, operators apply UV lighting systems to uncover precious stones and minerals. This method is safe and non-invasive, since it does not require workers to dig into the ground. Flashing the lamp over the location allows chemicals in gemstones to react to the light. Explosion proof (for safety) and short-wave UV bands are most effective for such operations.
- Crime Scene Analysis and Inspection: Forensic specialists and scientists commonly use UV flashlights to investigate crime scenes and evidence. Blood, urine and saliva all react to UV bands, which can be easier to detect in small amounts.
- Crowd Control: Businesses, concerts and other events can use UV light to verify tickets and bracelets at various entry points of the location. This is considered to be much faster than checking registration numbers. Workers at the event can also monitor beverages using handheld UV lights.
