Industrial Machine Vision Side Lit Backlight 2 Series

Side Lit Backlight 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 Side Lit Backlight are available in different sizes and light colors. The standard colors are White, Red, Green or Blue. On request also UV and IR Side Lit Backlight are possible. If you can't find the right size, we can customize the Side Lit Backlight to fit your illumination request. Click here for the datasheets.

When to use Side Lit Backlight in your machine vision application?

Side lit backlight 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 and edge defect inspection is requested.

How to use Side Lit Backlight for illumination

Side Lit Backlights are placed opposite of the camera and illuminating around an object. Triggering the Side Lit Backlight will increase its lifespan.

Production and quality control of Side Lit Backlight

Our LED side lit backlights 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 side lit backlight production is automated and involves placing the LEDs on a PCB that fits the side lit backlight, 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 side lit backlight. Post-assembly, the side lit backlight undergoes testing to ensure that performs according to its specification. This critical phase ensures that each side lit backlight unit meets our uncompromising quality standards.

The production process of the side lit backlight 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 side lit backlight 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 side lit backlight, we have established a room dedicated to light-source age testing.

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