Illumination for Visual Inspections

Improve Quality and Efficiency

Defects and errors in parts and components can negatively impact downstream processes, production efficiency, and product quality.

Visual inspection of parts and components can help manufacturers identify potential issues early on in the manufacturing process, minimizing lost product and production time. 

Proper lighting makes it easier for workers to perform visual inspections with fewer errors by providing uniform illumination, reducing eye strain, and improving contrast.

Poor Contrast, Hot Spots, and Eye Strain

Improper Lighting Can Lead to Mistakes

If compared to fluorescent lights, which tend to flicker from changes in intensity, the LED lighting is more ergonomic for an operator.  The inconsistent output of fluorescent light, plus the emission of UV and heat, can make it challenging to perform inspection tasks accurately.  Furthermore, the eye strain and operator fatigue caused by poor lighting can reduce both the speed and effectiveness of visual inspections.

In contrast, bright LED task lights provide stable, durable, and uniform lighting for quality inspection, which helps ensure accuracy and increase efficiency.  Ultra-bright LED lights from Banner Engineering will never require a bulb or ballast replacement over their more than 50,000 hours of operational life to provide years of maintenance-free illumination.

Even Illumination Improves Quality Inspections

Extremely Bright Light with no Hotspots

  • During the quality inspection of cars and automotive parts, bright, also, uniform light is essential to inspect parts properly.
  • The most important part of lighting up an automotive environment for inspection purposes is to find a light source that provides consistent, extremely bright light.
  • The energy-efficient WLB92 is easy to install and gives a consistent, bright light with no hotspots and minimal glare to inspect automotive parts.
  • Increased lighting can improve worker productivity and reduce eye strain, resulting in more reliable quality inspections.
LEDs are Low Maintenance and Save Costs

Years of Reliable Operation

  • Fluorescent lights often require multiple bulb replacements each year, as well as periodic ballast replacements.  Fluorescent lights can also lose intensity and become discolored, making inspections more difficult.
  • In contrast, LEDs provide intense, daylight white illumination that is distributed evenly across the inspection area. 
  • LED light bars, like the WLB32 from Banner, provide years of maintenance-free operation, with no bulb or ballast changes required throughout the lifespan of the device.

Choose the Right Light for Your Application

  • In some cases, overhead white light does not provide sufficient contrast for surface inspections of objects. 
  • When inspecting metal or plastic surfaces, imperfections such as fingerprints, dirt, or damaged areas can easily be overlooked. 
  • Green wavelengths are easiest for the human eye to see and adding green lights into the inspection area helps maximize the effectiveness of metal, glass, and plastic inspections.
  • Some oils also react to bright green lights, making oil spots more visible. This is especially important in the automotive industry where oil residue can cause fisheye imperfections, small circular spots that appear on contaminated surfaces.
