Abstract:

In view of severe radiation of UVB, bad on-site working conditions, easily leading to missed detection of traditional phosphor magnet powder flaw detection methods, the light source of phosphor magnet power flaw detection for tyre surface is optimally designed. A UV-LED light source is adopted as the excitation light source, it achieves matching between the UV-spectrum and the excited spectrum of the phosphor magnet powder. 108 UV-LED  light source arranged in arrays to obtain the high intensity and uniform illumination.The LED light source with filter glass filter out harmful ultraviolet ray and useless visible light. The results show that the designed UV-LED light source meet the requirements of phosphor magnet power flaw detection for tyre surface.

Key words: linear CCD, magnet power detection, ultraviolet radiation B, LED light source
