Spot Lights for Industrial Image Processing

Spot lights are extremely compact, robust and powerful at the same time. Thanks to the integrated zoom lens, the light can be precisely focused or diffused. They are ideal for point-precise illumination in industrial image processing, industrial automation, robotics, as well as for near and far-range identification applications.

Illumination Methods with Spot Lights

Illumination and vision systems that use spot lights typically work with the following illumination methods. Further specific methods are detailed in the descriptions of the individual products.

Brightfield

Using spot lights as an incident light causes reflections on the surface of the object being inspected due to the direct illumination. 

Low Angle

Placing spot lights at a flat angle creates contrast along the edges of the object, resulting in minimal illumination of the surface.

Darkfield

When spot lights are aligned flat, they clearly accentuate the contours of the object’s edges, while only a small proportion of light falls on the remaining surface.

Features of Spot Lights at a Glance

Spot lights impress with its robust aluminum housing with IP67 degree of protection, which reliably protects against dust and water. The M30 thread offers flexible mounting options. Thanks to the internal heat sink, they impress in both powerful strobe and continuous modes, ensuring uniform illumination even in challenging application environments. The integrated power control also optimizes the performance and reliability of this illumination technology.

Versatile Light Sources

wenglor spot lights are extremely powerful and bright, with an illumination intensity of up to 360,000 lux in strobe mode overdrive. They are available in the light sources white light, red light and infrared light.

Classification in the electromagnetic spectrum:
  • White light 5,700 K
  • Red light 630 nm
  • Infrared light 850 nm

Flexibility of the Zoom Lens

The lockable zoom lens allows a variable beam angle in the range of 4 to 26 degrees with constant homogeneity. With precise position repeatability, it provides precise visual field alignment to achieve optimal illumination with perfect Gaussian curve and high intensity. The easy manual adjustment allows quick adaptation to different working distances and makes the spot light ideal for industrial image processing applications where flexible illumination is of great importance.

Spot Light Applications

Spot Illumination for Robot-Guided Quality Inspection of Interior Parts


Before installing interior parts in passenger cars, the mounting elements must be checked for their presence and correct position. For this purpose, a smart camera with one spot light per side is mounted on a cobot. Due to the light weight and small size of the illuminations, they can be attached directly to the robotic arm. While the cobot scans the parts to be inspected, the spot lights provide precise illumination of the elements so that the camera can reliably detect each mounting element.
