Industrial Machine Vision Bar Light Combined Series

Bar light combined are industrial LED lights for illuminating products in machine vision

applications like surface defects on metal parts, character inspection on printed material, inspection of PCB components and positioning and recognition of large field objects in computer vision applications. Our bar light combined are available in different sizes and light colors. The standard colors are White, Red, Green or Blue. On request also UV and IR bar light combined are possible. If you can't find the right size, we can customize the bar light combined to fit your illumination request. Click here for the datasheets.

When to use bar light combined in your machine vision application?

Bar lights are the most commonly used lights in machine vision applications. They are very versatile. You can use them in combination with our industrial cameras in computer vision applications where you are inspecting:

Objects that are flat. In case an object is reflective, you need to adjust the angle of the bar light that there is no direct reflection into the camera image
Objects that are not flat and not reflective. These diffuse objects can always be illuminated with bar light combined

In case an object is not flat and reflective, we strongly recommend using a dome light for illuminating your product.

How to use bar light combined for illumination in computer vision

Bar light are commonly used in pairs of at least 2 pieces. For more complex applications, 4 or even more bar light are used. Using our bar light combined for a easy square setup of 4 bar lights. Optionally, we have diffusers and polarizers available. We recommend using the power supplies as indicated in the datasheet to control the brightness of the bar light combined. Additionally, these power supplies give you the option to trigger the bar light combined. Triggering the bar light combined will increase its lifespan.

Production and quality control of bar light combined

Our LED bar light combined are produced with a strict process of quality control, to ensure their reliability and consistency. Upon receiving a new batch of LEDs, the quality department completes a comprehensive check to test whether the wavelength falls within the specified tolerances. Approved LEDs are stored in a climate chamber, ready for use in production. The next stage of bar light combined production is automated and involves placing the LEDs on a PCB that fits the bar light combined, which is then followed by an inspection and soldering. Moving along the production line, the LED boards are assembled into the mechanical housing of the bar light. Post-assembly, the bar light combined undergoes testing to ensure that performs according to its specification. This critical phase ensures that each bar light combined unit meets our uncompromising quality standards.

The production process of the bar light combined may also include the creation of a diffuser or polarizer. The diffuser is cut automatically, and every batch of diffuser plates undergoes transparency testing before they are cut into the correct shape. The final step involves a comprehensive quality check, where the intensity, voltage, and current of each bar light combined are meticulously measured. This step guarantees that all machine vision lights that leave our facility meet the required specifications. To further ensure the long-term consistency of our bar light combined, we have established a room dedicated to light-source age testing.

During the R&D phase of a new bar light combined, it will be continuously on for 1 week, while the temperature is monitored. For every new production run, each bar light combined will be continuously powered for 12 hours, ensuring that the quality and output of our machine vision lights remain uniform over time.
