CIS – INDUSTRIAL APPLICATIONS
EXTERNAL LIGHTS
Outdoor lighting for CIS
Lighting Control and Synchronization
The CIS achieves optimal performance when using dedicated, synchronized and pre-configured light sources for direct software control.
The system operates via a strobe signal: the CIS sends a strobe-out signal to the lighting controller, which switches the light on and off at the programmed frequency. The light intensity must be adjusted according to the scanning speed: the faster the speed, the greater the light intensity.
Each CIS can manage up to three lighting channels, which can be used synchronously or independently. Available configurations can include, for example, RGB or White/UV/Infrared. Up to three light sources can be selected, combining them, for example, in a configuration with one internal light and two external lights, or with three external lights.
Connecting external third-party lights requires prior evaluation, as native synchronization may not be guaranteed and improperly aligned signals may compromise acquisition.
Operational difference between series
HLU – High Brightness Standard Linear Light
The HLU series is the general linear solution for industrial CIS applications. It is ideal when concentrated, uniform, high-brightness light is required across the entire scan width. It is suitable for reflection inspections, backlighting, and configurations with multiple illumination angles.

SHLU – High Brightness Surface Light
The SHLU series is a surface light for applications requiring illumination of a larger area, with high uniformity and high luminance. It is particularly suitable when the light angle and distribution need to be softer than a concentrated linear light.

JHLU – High Brightness Focused Light
The JHLU series is a focused white light, designed for applications requiring a more focused illumination than a standard linear light. It is useful when a sharper beam is required and contrast is increased in a specific area.

XH3LU – 45° oblique light
The XH3LU series is a 45° oblique white light designed to highlight defects that are best seen with side or angled lighting. It is useful when scratches, bumps, textures, or surface defects are not sufficiently visible with frontal lighting.
