Wenglor Debuts High-Intensity LBF LED Bar Light for Ultra-Fast Vision Inspection
Wenglor has expanded its machine vision portfolio with the launch of the LBF high-power LED bar light, a lighting solution engineered to meet the extreme demands of high-speed manufacturing lines. By delivering up to 2.5 million lux at a 200 mm distance, this new platform ensures that inspection cameras can maintain short exposure times, effectively neutralizing motion blur in dynamic sorting and scanning environments. The system’s sub-microsecond rise time allows for instantaneous synchronization with high-frequency conveyor movement, providing a critical upgrade for automated quality assurance workflows.
The LBF series is designed to overcome common challenges in industrial image processing, such as uneven illumination and poor contrast on fast-moving components. By utilizing a dense LED array and advanced optics, the device produces a highly stable light output that can be adapted to various setups, including darkfield, brightfield, and flat-angle configurations. A key innovation in this release is the "curve effect," which balances light distribution across the field of view when combined with external angle changers. This ensures consistent brightness and repeatable inspection results, which are vital for automated optical inspection (AOI) tasks in industries ranging from automotive tire identification to high-volume logistics and package sorting.
Installation and integration are streamlined through the light’s modular mechanical design, featuring a three-sided T-slot mounting system and a standardized M12 connector. The unit is available in 20 distinct lengths, spanning from 125 mm to 2,500 mm, allowing it to accommodate a wide array of conveyor widths and inspection tunnels. Constructed with a robust aluminum housing and boasting an IP65 ingress protection rating, the LBF series is built to endure the harsh conditions often found in heavy manufacturing and packaging plants. Because the controller is integrated directly into the housing, the device eliminates the need for bulky external control hardware, further simplifying system design and reducing overall footprint on the factory floor.
For manufacturers dealing with reflective or challenging surfaces, the availability of polarized versions ensures that glare is minimized, enhancing the visibility of fine details during barcode reading and surface defect analysis. As the move toward smart factory automation continues to accelerate, the LBF’s ability to provide high-intensity, synchronized lighting is becoming as significant as the camera and software layers themselves. By enabling sharper, more reliable data capture, Wenglor’s latest lighting solution offers a proactive way to maintain process reliability and prevent bottlenecks in high-speed, 24/7 industrial production environments.
