Production and quality control of Industrial lighting LED
Our LED manufacturing facility has implemented a strict process of quality control, this meticulous process is followed step by step to ensure the reliability and consistency of our products. 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 which is then followed by an inspection and soldering. Moving along the production line, the LED boards are Assembled into a mechanical housing. Post-assembly, the lights undergo testing to ensure that the lighting performs according to its specified function, especially machine vision lighting such as line scan lights. This critical phase ensures that each unit meets our uncompromising quality standards.
The production process of the machine vision lighting also includes the creation of diffusers. The diffusers are cut automatically and every batch of diffuser plates undergoes transparency testing before they are cut into the correct shape. It is standard that all of our bar lights and backlights are equipped with a diffuser. 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.
During the R&D phase of a new light, the light will be continuously on for
1 week to monitor the temperature. For every new production run of lights, each
light will be continuously powered for 12 hours. This ensures that the quality
and output of our machine vision lights remain uniform over time.

• Diffuse dark field ring light series (VA-RLDLA): Ring light series with diffuse dark field illumination, suitable for applications requiring enhanced contrast and shadow-free imaging.
Bar Light
Bar lights are usually used in pairs, it is used to minimize shadows and to illuminate the object evenly. Because the bar light position is adjustable it can be placed close to the object or next to the camera.
• Bar light series (VA-BL3): Versatile bar light series with 20 different sizes for various machine vision applications. Customizable positioning to minimize shadows.
• Combined bar light series (VA BLM3): Combined bar light series designed to enhance illumination, minimize shadows, and ensuring uniform lighting. Ideal for precision inspections.
• Long distance bar light series (VA BLLD): Long-distance bar light series provides illumination over extended ranges. Suitable for applications where distance is a critical factor.
Coaxial Light
Coaxial lights are suited for machine vision tasks where precise imaging and minimal reflections or shadows are crucial. Commonly used in inspections where a direct, on-axis light source is necessary to capture fine details without interference. Our customized coaxial lights includes:
• Coaxial light series (VA-COL2): Coaxial light series providing on-axis illumination for precise imaging with minimal reflections. Suitable for applications where direct light is necessary without interference.
Back Light
Back lights are employed in machine vision systems to create a silhouette effect or to highlight the contours of objects. Useful for applications requiring object detection, shape recognition, or separation from the background.
• Bottom lit backlight series (VA-BLBL2): Bottom-lit backlight series creates a silhouette effect or highlighting contours of the object. Ideal for applications that require object detection and shape recognition.
• Direct side backlight series (VA-BLSLH2): Direct side-lit backlight series providing focused illumination from the side. Suitable for applications requiring targeted lighting and enhanced contrast.
• Telecentric back light (VA-TCB): Telecentric backlight designed for precision imaging, ensuring light rays are parallel to the optical axis. Ideal for applications where accurate measurement is crucial.
Dome Light
The dome light is deal for machine vision applications that demand even and diffuse illumination. Commonly used in surface inspection tasks to capture fine details and defects without creating harsh shadows. It is generally used for highly reflective objects.
• Dome light series (VA-DL2): Dome light series providing even and diffuse illumination. Commonly used in surface inspection tasks to capture fine details and defects without creating harsh shadows, available in 8 different sizes.
Line Scan Light
Line scan lights are specifically designed for machine vision applications involving moving objects on a conveyor belt. Line scan lighting is designed to achieve high-resolution imaging by capturing and illuminating individual lines sequentially. This characteristic makes it particularly well-suited for applications requiring continuous inspection processes.

• High power line scan bar light series
(VA-LLHB2): High-power line scan bar light series for demanding applications requiring intense and focused illumination for moving objects on conveyor belts.
Spot Light
LED spots 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:
• Camera setups with a larger field of view
• Objects that are flat. In case an object is reflective, you need to adjust the angle of the LED spot 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 LED spots
We offer a versitale white LED spot that is delivered with interchangeable lenses, in order to change the opening angle. Beside the White option we can deliver this LED spot in many different wavelengths upon request.
Applications for machine vision lighting
Machine vision lighting plays a vital role in various applications across diverse industries, enabling accurate and reliable analysis of objects using machine vision systems. It is commonly used for surface inspection, defect detection, high contrast, object recognition, placement and the creation of silhouettes for part alignment.
In addition to these fundamental applications, machine vision lighting finds extensive use in quality control processes. It ensures the precision and consistency of manufactured products. The technology is employed in assembly lines to detect imperfections, irregularities, or deviations in dimensions, consequently contributing to the production of high-quality goods. Machine vision lighting is often used in barcode reading and identification tasks, improving the efficiency of logistics and supply chain management. Its versatility provides valuable insight into product quality and facilitates in the operation of automated systems by improving efficiency. As technology keeps evolving, machine vision lighting is on the verge of becoming even more critical when streamlining industrial processes and boosting overall efficiency.
Product life cycle management of Industrial lighting LED
Illumination in industrial machine vision applications is crucial. Machine vision lighting is employed for inspecting and controlling products, materials, and processes. Machine vision LED lighting has to meet strict requirements, such as constant light intensity, accurate colour rendering and long lifetime. A precise manufacturing process is needed to ensure these requirements. The lights within this category have a long-life cycle, therefore one can continuously purchase the same light with the exact same specs such as output for many years. Machine vision lights have a great batch reproduction and minimal LED characteristic variations between batches that could cause quality deviations.
Accessories to add to your machine vision lighting setup
A dedicated power supply offers several advantages over using the mains directly. By incorporating a dedicated power supply into your machine vision lighting setup, you can reap the benefits of consistent illumination, increased reliability, reduced energy consumption, enhanced control, and minimized electromagnetic interference. These advantages contribute to the overall effectiveness and longevity of your machine vision system. We recommend using a power supply like our commonly used 24V Power supply Set. A power supply like our 24V/60W Power Supply/Light Controller is advised when triggering the machine vision lights and controlling the light intensity is required for your application.
