UV-LED Lamps for fluorescent Magnetic Particle and Penetrant Testing in practice: Technical and practical requirements, new possibilities and upcoming standardisation of UV-LED lamps - (PPT)

摘要

LED-based UV-Sources are not simple electric lamps, they are electronic device that require adequate qualification and maintenances. NDT has the highest requirement for UV LED Sources due to its insecure security. Adequate qualification and additional electronic or manual process controls are required for secure an reliable usage of UV LED sources. Well qualified and designed high-quality UV-A-LED-sources can easily and completely substitute conventional bulb-based-UV-lamps without any technical and practical disadvantage in NDT. Fluorescent inspection processes can be improved using optimal UV LED sources. Fluorescent inspection processes can destroyed by using inadequate and unreliable UV LED sources.
