Lighting
Lighting is often the difference between a demo and a line that runs.
Backlights, ring lights, bar lights, dome/panel lights and strobe — each suited to different surfaces, speeds and defects. Sedeco designs illumination into the camera stack.
Types that decide image quality
Pick geometry for the surface — not for the brochure photo
Optimal lighting drastically improves extraction accuracy before any algorithm runs.
| Type | What it does | When we reach for it |
|---|---|---|
| Backlight | Silhouette, presence, edge gauging | Opaque parts, clear outlines |
| Ring light | Above the object, controlled shadows | General inspection, codes |
| Bar / directional | Direction and shadow for texture | Scratches, emboss, topography cues |
| Dome / panel (diffuse) | Soft, even light on shiny parts | Specular metal, curved packaging |
| Strobe | Freeze motion at takt | High-speed lines, conveyors |
Tied to architecture
Smart cameras often include lighting — until the surface fights back. PC-based cells get dedicated LED and controllers so intensity and timing stay deterministic.
Show us the surface and the speed
We propose lighting geometry with camera and lens — so Detect starts with a usable image.
