VISIOTRONIX · LED rings
LED rings for machine vision systems
The Photolux ring illuminators light the object along the optical axis thanks to the central aperture for coaxial mounting of the camera, reducing shadows and reflections. They are built with a high-density ring LED array and incorporate constant-current drivers (MCCD, with RCCR© on the DC6) for stable emission, and HTTM© technology for thermal management. The range comprises the DC5 and DC6 series with high-intensity direct light — with selectable beam angle (DC5) and up to 12,000 cd and 10 sizes (DC6) — and the DC7 series with diffused light and PWM control. They are available in white, blue, red and infrared, are powered at 24 Vdc with an M8 connector and are ideal for inspection, robot guidance and component verification.

How to choose an LED ring ↑ top
The choice depends on the type of lighting and on the size of the object:
- Type of light: direct and intense (DC5, DC6) or diffused (DC7)
- Central aperture for coaxial mounting of the camera
- Beam angle: selectable on the DC5 (15/30/45/120°)
- Intensity and sizes: up to 12,000 cd and 10 sizes on the DC6
- Colours: white, blue, red and infrared depending on the model

Typical applications ↑ top
LED illuminators for vision are used in numerous inspection, quality control and robot guidance applications. Some applications built and documented:
Special lighting for vision
Special lighting systems for in-line industrial vision: LED illuminators with direct, diffused, coaxial or backlight illumination to bring out the contrast and detail of the objects to be inspected.
Visual inspection of miniaturised components
The visual inspection of miniaturised components with machine vision systems calls for dedicated, uniform LED illuminators: the right light brings out defects and detail with accuracy and repeatability.
Vision systems for quality control
Machine vision systems for in-line quality control combine cameras and dedicated LED illuminators to obtain sharp, repeatable images for the automatic detection of defects.
LED ring illuminators for coaxial lighting ↑ top
Ring illuminators with a central aperture allow the camera to be mounted along the optical axis, giving axial lighting that reduces shadows and reflections. The DC5 and DC6 series offer high-intensity direct light, while the DC7 series provides a softer, diffused light.
See the DC5, DC6 and DC7 datasheets for beam angles, sizes, colours and part numbers.
