Dürr presents EcoReflect, an innovative light tunnel for accurate detection of flaws in car bodies painted surfaces. In order to check even the smallest flaws and irregularities in paint, like the inclusion of dust or small hairs, the system generates vertical contrast lines that allow the operator to follow the progression of the car bodies when checking them. In contrast to conventional systems with horizontal lines, with the Dürr system the operator does not have to keep looking up and down, ensuring a much more ergonomic and less physically strenuous environment.
The number of contrast lines in the field of vision is based on a suitable stimulus frequency, providing a reflected image with high but not too stimulating contrasts. EcoReflect use appropriate prisms at the lamps, ensuring that as much light as possibile is shone onto the car bodies with glare-free vision, minimizing fatigue symptoms for operators. Dürr has also enhanced the luminaire concept with the use of LED modules, achieving high contrasts in the reflected image and areas with homogeneous illumination. In addition, the LED technology requires just the half of the energy of conventional fluorescent tubes.
EcoReflect is also more economical than standard LED designs because the arched shape of the light tunnel casts a large amount of light onto the car body. EcoReflect can be constructed as an individual station or as a line. The system can also be extended and customized in terms of light colors and materials for complex flaw types detection.
