UV LED (Black Light) Inspection Light

UV LED lamps are used in Non-Destructive Testing (NDT) to inspect the surface for cracks inspection in Magnetic Particle Inspection (MPI) and Fluorescent Penetrant Inspection (FPI).

XEPU manufactures a range of mains and battery-powered, hand-held/portable UV LED lamps, UV LED torches (UV flashlight), and UV LED headlamps for different NDT applications to meet the demands of the general industry as well as the aerospace industry.

XEPU UV LED lamps are tested and complied with the requirements of ASTM E3022, and some of products are also in compliance with Rolls-Royce RRES 90061 and NADCAP standard.

XEPU UV Inspection Applications in Different Fields

Non-Destructive Testing (NDT)

Quality Assurance supervisors and NDT technicians can perform their fluorescent penetrant testing and magnetic particle inspection with confidence by using XEPU’s UV LED lamps either in-house or on the field at extremely tough environments. All XEPU UV LED lights for non-destructive testing (NDT) utilize a peak wavelength of 365nm or near all. XEPU’s UV lamps comply with standards and requirements as below:

ASTM E1444

ASTM E1417

ASTM E3022-18

ISO 3059-12

Rolls-Royce RRES 90061

Lab and Clean Room

XEPU UV LED lamps can be used to detect and reveal previously invisible soils and contamination where disease-causing bacteria and viruses can breed. It is of utter importance that the parts are clean prior to entering the assembly. Illuminating the parts with XEPU UV light prior to entering the clean room decreases the risk of contamination. It is a state-of-the-art method for verifying and improving cleanliness and sanitation in the most important areas of your facilities. XEPU UV LED lamps is widely used by labs and clean rooms of office, factory, hospitality, health care, food service and government agencies. XEPU UV LED lamps can inspect particles as small as 30μm that are not visible to the human eye and prevent contamination.

Hygiene & Sanitation

Detect urine and other body fluids, food stains, bacterial growths, mold growths, food spoilage, rodent contamination, and other unsanitary conditions.

Leak Testing & Leak Detection

XEPU UV LED lamps can detect leakage not visible to the human eye and identify leakage at an early stage. A wide selection of XEPU UV LED lamps can be used in combination with fluorescent dye to perform leak detection tests. In order to detect fluid leaks and their sources quickly, XEPU UV LED lamps can be used together with fluorescent tracer, which is the additives. This method is used by most manufacturers of petrol and diesel vehicle engines.

Gem & Mineral Inspection

The fluorescence of gems and gemstones is a result of UV radiation absorbed by the impurities or structural flaws of the stones. Detecting alternations and restoring cultural treasures, XEPU UV LED lamps have been used by gemologists, jewelers and hobbyists alike to identify the correct minerals either at a work environment or out in the open. Some minerals have the ability to temporarily absorb a small amount of light and release it at a different wavelength. This change in wavelength causes a temporary color change of the mineral, making it visible to the naked eye.

Art Conservation & Examination

XEPU UV LED lamps are excellent for detecting alternations and restoring cultural treasures in order to identify the authenticity of works of art or to inspect damaged or repaired paintings. Not only paintings can be examined with XEPU UV LED lights, but also pieces of art made of marble, jade, and ivory.

Forensic & Security Inspection

Many difficult crimes are solved with the help of XEPU UV LED light technology. Law enforcement officials, crime laboratories, police CSI teams and forensic professionals around the world can rely on XEPU UV LED Light products for a wide array of crime scene investigations (criminal investigations) and applications.

UV Inspection of Coatings on PCBs

Most PCBs manufactured are sealed with coating for moisture protection and water protection. So it is very significant that the coating is applied in a correct way on the PCB covering the components it is intended to. Some components are crucial to cover, others must not be covered. Inspecting the PCB with XEPU UV lamps ensure that the coating has been applied correctly.
