Résumé :	A new LED light tunnel makes the final inspections of painted vehicle bodies much simpler and more efficient. Adjustable light units allow the light emitted to be adapted to the colour of the body. The results are a higher surface quality and lower maintenance, energy and reworking costs.
Note de contenu :	- Better reflected image - Less reworking of pale-coloured paintwork - Reduced maintenance and energy costs - Fig. 1 : Comprehensive control options, which are coordinated with the employees' biorythms, allow more defects to be identified immediatly - Fig. 2. The vertical arrangement of the lighting elements allows strips of light in up to three different colours to be produced. this creates phase transitions where the defects (marked here in th epicture) can be more easily identified - Fig. 3. The clearer the reflected image, the easier it is to spot faults. The reflected image is harder to see on pale-coloured vehicle
