The choice of Dehong industrial light source

1. Ring light source:

Light exit angle value is 0 ° ~ 90 °

0 ° ~ 45 ° is a low-angle ring light source. Current application examples include glass dust scratch detection, metal frame scratch detection, smooth surface scratches, and damage detection to achieve the effect of highlighting the contours and scratches of objects.

 The light emission angle of 60 ° ~ 90 ° focuses on the surface of the test object, highlighting the different characteristics of the surface of the object. Application cases include: detection of inductive tin surface, character detection, pin detection of different data interfaces, and plane code detection.

Coaxial light source

High-intensity and uniform light passes through the beam splitter and is coaxial with the lens. Special materials are used to suppress ghosting caused by reflections. Improve imaging clarity. It is suitable for scratches and printing detection on the measured stool surface with high reflectance. Application cases include: laser marking characters, two-dimensional code recognition, scratch detection on the surface of objects with high reflectance.

3. Bar light source

This light source is characterized by its flexible and compact size, which can be adapted to different positions, and is mainly suitable for detecting large square structures.

Current application cases include cracks and QR code reading. Edge detection, silkscreen text detection.

4. Four-sided adjustable light source

Four independently adjustable bar-shaped light sources, which can independently control the brightness, flexible installation, high brightness and high-precision lighting. Application area: Inspection of flat package on four sides. QR code reading, ceramic packaging surface inspection.

5. Bottom backlight

The bottom-illuminated standard backlight can be applied to the microscope stage, highlighting the outline of the measured object and providing high-brightness backlight illumination by a high-density LED array. Detect burrs, stains and scratches on transparent objects.

6. Square shadowless light source:

Suitable for rectangular and irregular test objects, providing rectangular field of view. Application cases: Battery board disconnection detection, mobile phone cotton, edge correction of film position, one-dimensional, two-dimensional code recognition.

7. AOI special light source

It has the characteristics of high brightness, good uniformity, and high spatial resolution; three sets of independently controlled ring light sources illuminate the circuit board at high, low, and low angles, which effectively eliminates component electrodes, pads, and solder joints on the circuit board The characteristics of the slope are highlighted. Application field Multi-level object detection, plug-in solder joint detection, placement, solder inspection.

8. Point light source

The unique light-concentrating effect (light guide) is used to achieve uniform illumination. It is beneficial to include liquid crystal glass circuit detection, glass surface scratch detection, and character detection at the bottom of the plug.

9. Linear light source

Linear light, high-intensity light illumination, current application cases: bumps, scratches, and stain detection on the surface of mobile phone casings. Use special lenses to make the light come out linearly and keep it even and smooth.

10. Dome shadowless light source

After the light is reflected by the spherical diffuser, it radiates smoothly and evenly on the measured object, which is suitable for the uneven and reflective object on the surface of the measured object. Application cases for surface, surface bump, and arc detection. Metal and glass reflective surface detection.

11. Parallel light source

 Light travels in a straight line with high brightness and uniform brightness. It is mainly used for high-precision detection. Used in conjunction with a telecentric lens, it can be used as a backlight.
