Ultraviolet LED flashlights is a new world of possibilities that LED R&D labs have broken into. UV light is not directly visible to human eye, but some materials reflect an altogether different color helping us identify the existence of that material which is not otherwise discernable by naked eye.
UV LED flashlights are now used for wide range of purposes. Some of them are listed below:
- Detect fake money
Currency notes have hidden lines and logos that are not visible to naked eye. These lines and logos are enhanced when viewed under UV light. For this reason, UV LEDs are widely used to detect fake currency, which may not have the invisible lines or logos in the right place.
- Inspect jewelry collection
Authentic jewelry will have certain marks that are indiscernible to the naked eye, but can be seen under UV lights proving its authenticity. Hence, UV LED Flashlights are used to check the authenticity of the precious stones.
- Reveals Pet Urine In Carpets And Furniture
Homes that allow pets inside, we cannot be sure of fluid excretions from pets smeared on our sofas or beds. These stains come alive, if we shine UV flashlight over the surface. Inspecting the sheets with the room lights off will allow better visualization of the stains.
- An Essential tool for law enforcement, postal inspections, customs, medical forensics.
Crime scenes and other areas where inspection of chemicals or mineral compounds are required is another field where UV LEDs plays a major role. UV LEDs are the most reliable and easy method of detecting relevant indicators under the domain of enforcement agents, investigators, and inspectors.
- HVAC repair
UV LED lights help locate even the smallest of leaks in air conditioning and refrigerator coils by adding a fluorescent dye. The leaking spots are easy to identify under UV light inspection.
- Antique authentication
With a burgeoning population of the mega-rich in our booming cities, there has been an explosion of interest in art and an insatiable appetite for antiques, which is being fed a good measure by forgeries. An expert in antique trade or preservation can locate forgeries and authenticity by using UV LEDs. Modern paints have a lot of chemicals, especially phosphors that are sensitive to UV lights. Whereas, older paints do not have as much chemical or nil chemicals. Therefore, forgeries of old paintings will show paint that is sensitive to UV light, as these forgeries have used modern paints. All modern paints have phosphors as one of the important ingredients. So, it is not possible for even the best forger to recreate a masterpiece without modern paints and it would be impossible for a forger to create a paint on his own that is phosphor free.
- Adhesive curing
UV LEDs are used to detect improper sealing of the parts that have been adhered to by chemical adhesives. By shining UV light, one can notice inconsistencies in the surface or gaps between the joined parts.
- Detecting bacteria
Pools or patches of some bacteria can be discerned by shining UV LED over them, as some bacteria fluoresce under this light. Hence, it is possible to monitor the growth of bacteria and trace them.
- Night Club hand stamp screening
Hand stamps are invisible logos or designed specifically for that particular nightclub, amusement park, parties, and other events wherein people are stamped, if their entry is approved. Visible stamps can be duplicated with an ease. These stamps are invisible, and become visible under UV light; it is not easy to work around in duplicating them in a short span of time. These stamp inks are available in many colors and appear as UV blue, neon green, pink, yellow, orange, black, blue, red, green, violet, etc.
- Fabric and Textiles
Collectors of antique clothes use UV light to detect the age of clothes based on the fact that clothes made after World War II have chemicals that fluoresce under UV light.
- Fluorescent dye leaks
Leakages in pipes in automobile related to air-conditioning, coolants, oil, brake fluid, etc. can be detected by using a fluorescent dye, which can be detected through leaks under UV light.
- Glass and glass repair inspection
Glass paints belonging to certain era fluoresces a paint specific color that is known to art experts. Depending on whether the paint fluoresces or not, one can conclude the authenticity of the glass artwork.
- Human bodily fluid tracing
Besides, the UV light reveals human body stains like semen, saliva, or traces of blood on bed sheets when shone under UV light.
- Hunting/animal blood tracking
On the other hand, the UV flashlight can be used to locate game hunted animals, which have been shot by tracing the track of blood left by it.
- ID and document Verification
Whereas, the UV LED flashlight can be used to discern watermarks or other holograms used to check the authenticity of certificates or other legal documents.
- Mineral lighting and identification
Photoluminescence characteristics of minerals under UV light is an easy method of identifying different types of minerals.
- Reading invisible fluorescent inks
Some documents or jottings written with fluorescent ink is not visible to naked eye. Such notes or writings can vividly be read under UV LED flashlight.
- Scorpion illumination
Scorpions and insects can be easily identified using UV lights even if they are camouflaged or hiding in the total darkness.
Psoriasis is a skin disease, which can be treated using UV light. When skin is exposed to UV light, it leads to increased production of vitamin D in your body, which plays a vital role in the absorption of calcium.
The above listed uses of UV rays are the main reason why the market of UV LED flashlights is expanding. These inspections and tests can be easily done with the help of compact and powerful UV LED flashlights. Apart from this, its usage are increasing day by day. In addition to that, these UV LED flashlights are rechargeable. They are handy and easily portable. Moreover, easily available in the market and quite affordable.
