What Is an AOI Light? Can Different Colors Be Controlled Separately?

AOI (Automated Optical Inspection) lights are designed using an array of RGB high-brightness LEDs, allowing for illumination from various angles and in different colors. Essentially, AOI lights are a combination of high-angle and low-angle light sources.

Characteristics and Functions of AOI Lights:

AOI lights have unique characteristics and offer significant benefits:

1. Combination of High-Angle and Low-Angle Light

AOI lights can combine different angles of illumination, providing flexibility in how the light source interacts with the object being inspected.

2. RGB Multi-Color Combination

These lights feature a combination of RGB colors, allowing for varied illumination for different inspection needs. This flexibility is particularly useful when inspecting complex objects or when you need to highlight specific details.

3. Customizable Angle and Color Combinations

Since AOI lights support different angles and colors, they can be customized to meet specific inspection requirements, providing a three-dimensional perspective of the object.

4. Separate Control of Colors

One of the main advantages of AOI lights is that the different colors (red, green, blue) can be controlled independently. This feature allows for greater flexibility in setting up inspections and fine-tuning the lighting to achieve optimal results.

Applications of AOI Lights:

Given their unique characteristics, AOI lights are suitable for a wide range of applications, including:

1. PCB Solder Joint Inspection

AOI lights can highlight three-dimensional features on PCBs, allowing for precise inspection of solder joints and other electronic components.

2. Inspection of Reflective Surfaces

With the addition of a diffuser, AOI lights can minimize reflections, making them suitable for inspecting smooth and shiny objects.

3. Automated Optical Inspection

These lights are commonly used in automated optical inspection systems, providing flexibility and precision in industrial inspection tasks.

Conclusion:

AOI lights offer a versatile and flexible lighting solution for machine vision applications. The combination of different angles and RGB colors allows for customizable and separate control, enabling detailed inspection with a three-dimensional perspective. These characteristics make AOI lights ideal for a variety of applications, including PCB inspection, electronic manufacturing, and other industrial processes.
