Industrial Machine Vision Ring Light 3 Series

Ring light are industrial LED lights for illuminating products in machine vision

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

When to use ring light in your machine vision application?

Ring 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:

Flat objects where you want to measure edges or detect surface defects
Objects that are round

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

How to use ring light for illumination in computer vision

Ring lights are commonly used in machine vision applications. We recommend using the power supplies as indicated in the datasheet to control the brightness of the ring light, optimizing illumination for your computer vision tasks. Additionally, these power supplies give you the option to trigger the ring light. Triggering the ring light will increase the lifespan of the ring light combined.

Production and quality control of ring light

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

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

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