The powerful backlights are available in two sizes.

B&R has developed and patented a comprehensive lighting system for its vision solution. Lighting control is synchronized with the automation system in the sub-µs range. The modular light bars and selection of backlights ensure optimum results even in difficult lighting situations.

  • Highlights
  • Lighting control with µs precision
  • High-performance LEDs (immune to extraneous light)
  • Automatic adaptation to every situation

Data sheet:

As integral parts of the automation system, both cameras and lighting are easy to synchronize with other sensors, motor positions and events in the machine application. Lighting control with microsecond precision is even guaranteed when synchronizing multiple cameras and light sources.

Each light has an integrated strobe controller, so no external hardware is required. The controller ensures a precise pulse current supply to the powerful LEDs. This enables light pulses of at least one microsecond duration at maximum intensity. The B&R vision system can therefore also be used for high-speed applications without any problems.

The flexible light bars feature electronic angle adjustment and make it possible to implement bright-field illumination (left) and dark-field illumination (right) with the same device, simply by changing a single parameter.

Consistent high performance

The flexible light bars are available individually or arranged as ring lights in groups of four, six or eight. The backlights are available in two sizes. Each light can feature up to four different LED colors at a time. The selection ranges from white and various visible colors to infrared and ultraviolet. This makes it possible to achieve just the right contrast, color, illumination and intensity for any application.

Immune to extraneous light

The advantages of high-performance lighting are not only that it allows fast exposure of rapidly moving objects, but also that it almost entirely eliminates the influence of extraneous light – an often underestimated source of errors. Suppression of extraneous light is a crucial factor in the quality of inspection and measurement results.

Ring lights are comprised of either four, six or eight light bars, and provide exceptionally homogeneous illumination.

Factory calibrated

B&R calibrates its light bars and backlights prior to delivery. This means that lighting components can be exchanged in the field without requiring any changes to the machine vision application. Since LED intensity varies with changes in temperature, B&R has also integrated temperature tracking to adjust LED power automatically.

Simple cabling

Integrated into the machine network via an M12 hybrid connector, which also supplies the necessary 24 VDC power, B&R lighting systems each need only a single cable. A second hybrid connection enables daisy-chain cabling with additional lights or the camera.

Runtime flexibility

Many machine vision applications require very precise alignment of the light source to achieve good results. B&R's light bars therefore offer electronic angle adjustment from -40° to +90°.

When producing multiple products on the same machine, the lighting angle can be optimized between batches – simply set it once for each product and save it as part of the batch recipe. The electronic angle adjustment on the ring lights makes it possible to optimize the light cone.

Adjust the configuration at any time

Just like the angle of the light bars, all other lighting parameters can be configured at runtime to optimize illumination or adapt to new products. Combining LEDs of different colors makes it possible to adjust the wavelength at runtime to optimize contrast. Diagnostic data can be read from the lights at any time thanks to their network connection.

Powerful backlights

Available in two sizes, the backlights are extremely powerful. Like all other B&R lighting, they include a built-in strobe controller and can be used extremely flexibly thanks to the four light colors that can be changed at runtime. The light intensity is completely homogeneous, an essential requirement for reproducibility in measuring applications.
