Industrial machine vision diffuse flat ring light 2 series

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

When to use diffuse flat ring light in your machine vision application?

Diffuse flat 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:

Objects that are flat. In case an object is reflective, you need to adjust the angle of the diffuse flat ring 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 diffuse flat ring light

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

We recommend using the power supplies as indicated in the datasheet to control the brightness of the ring light. 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.

Production and quality control of diffuse flat ring light

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

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

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