LED Bar Lights for Machine Vision
Linear LED bar lights delivering uniform, high-output illumination across a wide flat field — the workhorse lighting format for line-scan and area-scan inspection.
What Is an LED Bar Light Used For?
A bar light is a linear array of LEDs behind an optical diffuser, mounted at a direct or grazing angle to illuminate a flat or gently curved field of view. It's the default choice for conveyor-line inspection, label and print verification, and any application needing even illumination across a wide, elongated area — where a dome light would be used instead for reflective or curved parts, and a coaxial light for specular, mirror-like surfaces.
Angle of incidence equals angle of reflection — the geometry behind every direct lighting setup.
Technical Highlights
- Industrial design: aluminum body for heat dissipation, integrated M12 connector for a standardized wiring harness.
- Hardened 24VDC electronics built for continuous production-line duty.
- Uniform light output across the full bar length via an opal diffuser, minimizing hot spots.
- Multiple LED wavelength options: White, Red, Blue, Infrared (availability depends on configuration).
- Compatible with continuous and strobe/overdrive operation for high-speed lines.
| Light Field / Beam Type | Wavelength Options | Typical Optical Window | Operating Mode |
|---|---|---|---|
| Standard Direct Beam | White, Red, Blue, Infrared | From 50mm to 500mm active length (configuration dependent) | Continuous or Strobe/Overdrive |
| Wide Diffuse Beam | White, Red, Infrared | From 50mm to 500mm active length (configuration dependent) | Continuous or Strobe/Overdrive |
| Narrow Focused Beam | White, Red, Blue, Infrared | From 50mm to 500mm active length (configuration dependent) | Continuous or Strobe/Overdrive |
Dimensions and optical windows shown are generic and given as typical ranges. Exact figures depend on the configuration selected — available on request from our engineering team.
