coReflect from Dürr is an innovative light tunnel for checking surface quality (Fig. 1). With an innovative light concept and a perfectly ergonomic environment design, it delivers precise and highly focused vision. This permits continuous detection of irregularities in paint with maximum accuracy. Before car bodies leave the paint shop and go into final assembly, the paint structure is checked for the smallest flaws like inclusions of dust or small hairs. The EcoReflect light tunnel provides the best visual and ergonomic conditions for this difficult quality inspection task.

A Focused and Accurate Detection of Flaws With EcoReflect: An Innovative Light Tunnel for Checking Painted Surface Quality fatigue symptoms for operators. With EcoReflect, appropriate prisms at the lamps ensure that as much light as possible is shone onto the car bodies, and that the operators are not subjected to glare. The radiation principle of asymmetric lighting helps here.
Dürr has also enhanced the luminaire concept with the use of LED modules. The result is both high contrasts in the reflected image and areas with homogeneous illumination. The LED 1 technology used requires just the half of the energy of conventional Figure 1: The innovative EcoReflect light tunnel offers the fluorescent tubes. EcoReflect is also best visual and ergonomic conditions for checking the more economical than standard LED quality of painted surfaces. Detecting deviations calls for a reflected designs because the arched shape image with high, but not too stimulating, of the light tunnel casts a particularly contrasts. With EcoReflect, the number of lines, with this system the operators do large amount of light onto the car body. contrast lines in the field of vision is also not have to keep looking up and down, EcoReflect can be constructed as an based on a suitable stimulus frequency. which is much more ergonomic and less individual station or as a line. The system can Since it generates vertical contrast lines, the physically strenuous. also be extended and customized in terms of operators can follow the progression of the Glare-free vision is another important light colors and materials for complex flaw car bodies when checking them.
