Wenglor Introduces High-Power Illumination for Vision Systems

Wenglor recently released its LBF high-power LED bar light, delivering up to 2.5 million lux at a distance of up to 200 mm. It features a very fast rise time of 800 ns, which helps improve image quality and inspection reliability in demanding industrial settings.

The LBF LED Bar Light

Industrial inspection systems rely on cameras to capture clear images of fast-moving products on conveyor belts, making good lighting essential. Poor lighting forces cameras to use longer exposures, which can cause motion blur and hide defects.

Wenglor's new LBF high-power light bar is built for these demanding conditions, using advanced optics and a dense LED array to maintain stable image quality during fast operations. Its lighting can be precisely synchronized with camera exposure and conveyor movement, making it suitable for scanning tunnels, high-speed sorting, and dimensional inspections.

The LBF delivers up to 2.5 million lux at 200 mm, making it possible to inspect larger areas and see fine details clearly. Its rise time is under 1 µs, so it reaches full brightness almost right away. This helps cameras capture sharp images of fast-moving objects with very short exposure times.

The LBF runs at a peak current of 0.5 A and an average of 0.35 A per 125 mm segment. It also includes a built-in controller, so users don't need extra control hardware.

Easy Integration With Existing Systems

The new LBF is easy to install, thanks to three-sided T-slot mounting that lets users quickly position the light for different applications. It comes with an integrated sliding T-slot nut and a variety of mounting accessories to simplify setup.

The bar light is available in 20 lengths, from 125 mm to 2,500 mm, to fit different installation needs. A standard M12 connector makes setup quick, and the tough aluminum housing with an IP65 rating means it can handle harsh environments.

Optical Innovations Improve Illumination

The LBF LED bar light can use angle changers to adjust the beam angle for different distances and applications. Users can add these accessories without opening the device, so the IP65 rating is maintained. Polarized versions are available for reflective or shiny surfaces.

The company has also introduced the “curve effect.” By combining angle changers with different beam types, the system balances light across the field of view to reduce changes in brightness. This creates more even illumination, which helps make inspections more stable and repeatable.

The LBF supports several common lighting methods in machine vision, such as flat-angle, darkfield, brightfield, and dome-effect setups. This means one lighting platform can adapt to many different inspection needs.

Built for High-Speed Machine Vision

In logistics, the new bar light helps with OCR, package identification, scanning tunnels, and barcode reading. It is also useful in packaging for checking labels and inspecting codes on fast-moving lines. In automotive, the LBF bar light can be used for inspecting large parts, finding dents, and reading markings on dark tires.

As manufacturing environments require faster performance and higher quality, the new LBF high-power LED bar light can help maintain process reliability. It may become just as essential for fast inspection tasks as the cameras and software that rely on it.
