Ring Light, 90mm, white, 24V / 9W, VA1-RL3-90-70-W

Industrial Machine Vision Ring Light (90mm white) Ring lights 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. Our 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 ring light are possible. If you can't find the right size, we can customize the ring light combined to fit you illumination request. The VA1-RL3-90-70-W is available on express stock. Click here for the datasheets. When to use 90mm white 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 applications where you are inspecting: Objects that are flat, and 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

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. Additionally, these power supplies give you the option to trigger the ring light. Triggering the ring light will increase its lifespan.

Production and quality control of 90mm white ring light

Our 90mm white LED ring lights are produced with a strict process of quality control, to ensure the reliability and consistency of our ring light. 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 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 for the ring light are assembled into the mechanical housing of the ring light. Post-assembly, the ring light undergoes testing to ensure that the ring light performs according to its specification. This critical phase ensures that each 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 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, the ring light will be continuously on for 1 week, while the temperature is monitored. For every new production run of ring light, 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.
