Industrial image processing relies on precise illumination to detect fine surface structures and minimal material deviations. The LBF high-power bar light developed by wenglor is engineered to deliver high-intensity and uniform light patterns across large illumination widths. This lighting system targets applications requiring consistent reproducibility and stable inspection results, particularly in automated environments with high cycle times such as scanning tunnels, high-speed sorting, and dimensional measurement.
Optical Output and High-Speed Synchronization
Maintaining image stability during high-speed operations requires short exposure times and high light intensity to prevent motion blur. The LBF bar light generates a light output of 2.5 million lux at a working distance of 200 millimeters. Coupled with a rise time of 800 nanoseconds, this fast response mitigates motion blur during dynamic image capture. Precise electronic synchronization between the LED light pulses, camera exposure, and conveyor speed establishes the necessary conditions for capturing high-contrast images in continuous-flow industrial processes.
Integration and Power Specifications
Despite the high optical output, the hardware maintains low power consumption through an integrated controller. The system draws a peak current of 0.5 amperes and an average of 0.35 amperes per 125 millimeters of lighting length. Mechanical integration into existing machine vision architectures is facilitated by a standardized M12 plug connector and T-slot mounting points located on three sides of the unit. To accommodate specific field-of-view parameters, the LED bar light is compatible with external angle changers. These optical accessories allow operators to adjust the beam angle, ensuring uniform illumination distribution across the entire visual field of the vision system.

In the industrial machine vision sector, standard industrial LED bar lights typically offer illumination intensities between 100,000 and 500,000 lux at a 200-millimeter working distance, with rise times frequently ranging from 10 to 50 microseconds. The 2.5 million lux output and sub-microsecond rise time of the LBF series accommodate ultra-high-speed line scan and area scan applications where camera exposure times must be restricted to single-digit microseconds to prevent image degradation. These operational parameters are primarily utilized in demanding automated optical inspection (AOI) setups, such as semiconductor manufacturing, high-throughput packaging, and advanced logistics sorting systems.
