Light for Industry and Engineering Surface-Check Lighting

Quality Lighting for Quality Control

Intelligent machines are increasingly replacing manual labour, yet people are still crucial when it comes to quality control. Why is that? The human eye has the unique capacity to check for subtle flaws and irregularities on different surfaces. However, detailed inspections can only be performed effectively in optimal ambient conditions – making quality lighting an essential part of quality control.

The right lighting concept for demanding visual tasks depends on the type of products that need to be inspected. It is therefore crucial that the lighting is tailored to suit the particular surfaces, colours, reflections, shadows and dimensional characteristics. This includes surface inspection areas in the automotive industry, where the coatings, paint finishes and materials of components such as doors, bumpers, hoods and panels have to be painstakingly examined. Various surface-finished products in the metal industry, chrome finishes on kitchen and bathroom appliances and plastic or patent...

Quality inspections are often carried out in poor conditions, as un­ suitable lighting leads to irritating problems like glare. This means that the work requires more time and effort, while faults or imperfections are often missed. The right light affects employee performance and dictates the quality of the final product, making it an essential consideration for any company. When it comes to surface-check lighting, it is therefore vital that the lighting solution meets the particular requirements of the specific materials and finishes.

Light is human centric. Fault Detection Aim and function are key aspects of any product. Yet few items are chosen purely with practical considerations in mind, as factors such as the quality of finish and a complete lack of faults often have a major influence on the final purchase decision. No one wants to buy goods with a scratch, a dent or an imperfection, so selection – and indeed rejection – of materials is now a key part of any manufacturing process. Industrial Safety and Well Being The benefits of the right lighting for a company and its employees are quite clear: fewer mistakes, increased...

Cost Effectiveness Long production hours in the automotive industry generally translate into substantial energy requirements. This puts the emphasis firmly on energy efficiency – which is exactly where the right lighting solution can make a valuable contribution. With an average service life of 50,000 hours and a guaranteed end-of-life luminous flux in excess of 90 per cent, industrial LED luminaires from Zumtobel have been specifically designed for demanding environments, where long operating life and the lowest possible drop in luminous flux are both im­ portant factors. Easy Installation and...

COESA is the first quality-control luminaire from Zumtobel. Sharper than the human eye, this task-specific luminaire perfectly complements general lighting and utilises optimal area lighting to find any fault and irregularity in installations where the highest quality is of the highest importance. By illuminating the task area from an appropriate distance, COESA delivers planar, uniform and shadow-free light onto the object that needs to be inspected. This kind of area lighting is particularly helpful when it comes to locating bumps, dents or imperfections on matt, shiny and transparent surfaces....

Colour contrast COESA’s fault detection technology is further optimized by colour temperature contrast and precise pattern lines, which can be specified in three different configurations. By creating the right degree of contrast, the reflex picture shown on the inspected surface is highlighted, thus making it easier to detect defects on any paint colour. The pattern lines, on the other hand, ‘mutate’ depending on the grade of fault. When the inspected surface is free from blemishes, the lines remain parallel. If there is any kind of flaw, the lines immediately ‘stick together’. The Italian term...
