LBT Miniature Bar Lights

The LBT mini bar light brings powerful LED lighting into compact mounting spaces. With flexible mounting options, adjustable beam angles using angle changers, the linking of several luminaires and different light sources, it creates new possibilities for industrial image processing in confined installation situations.

Mini Bar Light: More Options in the Smallest Spaces

Space-Saving Illumination for Compact Installation

Whether in the automotive industry, logistics or electronics production: The LBT mini bar light is suitable for applications with limited installation space and short working distances, as well as for integration into existing systems with little clearance. Mounted close to the test object, it enables detailed illumination of small visual fields. Typical applications range from surface inspection to code reading and electronics testing.

Electronics

  • PCB inspection in compact test setups
  • Inspection of solder joints, pins and contacts with compact integration close to the test object
  • Display test with small visual fields and homogeneous illumination

Other Key Features of the LBT Bar Light:

The right light source

Four light sources are available for optimal illumination of different materials and surfaces: white light (5,700 K), red light (630 nm), infrared light (850 nm) and blue light (470 nm).

Protected in use

The anodized aluminum housing has an integrated ventilation membrane that prevents condensation from forming in the unit. The IP67 degree of protection allows use in harsh industrial environments.

Seamless integration

Fully compatible with modern machine vision cameras and smart cameras for a wide range of working distances and industrial image processing applications.

Compact Illumination, Big Ideas

Small format, versatile use: The LBT mini bar light shows how much flexibility is in compact LED lighting. The video provides an overview of the key features of the LBT mini bar light, such as the highly flexible cable, the versatile mounting options, the linking of several lights and the adjustment of the beam angle with angle changers.

Maximum Freedom of Integration Down to the Last Detail

Highly Flexible Cable, Countless Mounting Options

The LBT mini bar light is characterized by a highly flexible cable that connects the light to the power supply unit. Due to its compact form factor and flexible cable, the small bar light can be easily mounted in applications where space is limited.

Further mounting options for the mini bar light are provided by the M4 T-slot and four M2 threaded holes on the rear of the light. The power supply unit also has two M4 threaded holes for mounting.

Need Even More Freedom of Movement for Your Illumination Solution?

We offer the optional ZBTZ001 bar clamp for mounting the LBT mini bar light on aluminum profiles. This system allows full 360 degree rotation in the horizontal plane and 180 degree movement in the vertical plane.

Linking of Multiple Bar Lights

The innovative design of the LBT mini bar light allows two or more devices to be mounted side by side while maintaining the standard LED spacing. This enables seamless integration of several miniature bar lights without creating interruptions in the light spot. Even for illumination of larger areas, the LBT series remains the optimal choice for industrial image processing applications due to its outstanding performance and flexibility.

Changing the Beam Angle with Angle Changers

An angle changer is a special scattered light diffuser that can be mounted directly on the LBT mini bar light. It extends the beam angle and thus improves the light distribution over the entire visual field, resulting in homogeneous illumination.
Angle changers make it quick and easy to check the feasibility of new projects to find the ideal illumination solution. As the product does not need to be dismantled to adjust the beam angle, the protected IP67 design integrity is preserved. At the same time, angle changers enable high versatility for different working distances and applications in industrial image processing.

Easy and Quick Installation of the Angle Changers

The simple and flexible magnetic attachment is suitable for testing purposes, while the angle changer can also be fixed with screws for continuous mode.

The angle changers for the LBT mini bar light are also available in a polarized version.

Continuous and Flash Mode OverDrive

The mini bar light can be used in continuous mode or flash mode OverDrive depending on the application. While continuous mode provides constant and even illumination, flash mode OverDrive provides higher irradiance during image capture. This also makes it suitable for short exposure times and dynamic processes.

Illumination Methods with Miniature Bar Lights

The right illumination method is crucial for reliable image evaluation. The LBT mini bar light enables various illumination technologies to highlight relevant features of the test object in a targeted manner. Further specific methods are listed in the respective product descriptions.

Brightfield
By using miniature bar lights as incident light, direct illumination causes reflections on the surface of the object being examined.
Darkfield
Positioned as a flat aligned illumination, the bar light highlights edges strongly while hardly any light falls on the surface.
Flat angle
Using bar lights at a flat angle enables a contrast to be created at the edges, which allows slight illumination of the surface.

LBT Machine Vision Illumination in the Application

Code and BBD Reading on Cans

In the food industry, barcodes and the best before date (BBD) on cans must be read reliably in-process. Sufficient illumination is required for a machine vision camera to reliably recognize the data. A small bar light installed on the side of the conveyor illuminates the entire scanning area, enabling reliable code and BBD reading on cans. Its small dimensions and IP67 degree of protection make the bar light suitable for use in confined spaces and harsh ambient conditions.

Surface Inspection of Headlights and Taillights

In the automotive industry, headlights and taillights must be free of scratches, sink marks and contamination. However, the transparent polycarbonate lenses are highly reflective, so white light causes glare and fluctuating contrast. A bar light with blue light reduces disturbing internal reflections thanks to its short wavelength and highlights fine surface defects. Together with the B60 smart camera, high-contrast, reproducible images are created for reliable inspection with fewer pseudo errors, even at high cycle rates.
