High-output illumination for fast line-scan inspection
LXV-4LINH is a fan-cooled line scan light for high-speed line-scan cameras. Its focused linear output is suited to steel plate, glass, metal surfaces, contour edges, printed materials, PCB and chip inspection, and continuous web materials where the camera must preserve defect contrast at production speed.

Surface defect contrast
Use the narrow illuminated line to reveal scratches and surface defects as a cylindrical or flat target moves past the camera.
Continuous-material inspection
Configure the emitting length and camera field of view for glass, metal, film, print and other continuous production materials.
Contour and edge imaging
Use controlled linear illumination when the inspection task depends on stable edge or contour separation.
Illuminance decreases as working distance increases
The LXV-4LINH400-W reference data also shows the illuminated width increasing with distance. Set working distance only after confirming both the required brightness and the line width on the target.
| Working distance | Illuminance | Emitting width |
|---|---|---|
| 0 mm | 3,200,000 lx | 8 mm |
| 50 mm | 2,200,000 lx | 8 mm |
| 100 mm | 1,670,000 lx | 10 mm |
| 150 mm | 1,290,000 lx | 13 mm |
| 200 mm | 1,000,000 lx | 16 mm |
Values are performance references for the stated model and setup. Illuminance decreases and the emitting width increases as working distance rises.
What changes from 3LINH to 4LINH?
- Illuminance
- 1.6× 4LINH: 3,200,000 lx; 3LINH: 2,000,000 lx
- Weight
- 35% lower Compared with 3LINH
- Volume
- 20% lower Compared with 3LINH
Cylinder surface defects appear with stronger contrast
In the reference setup, LXV-4LINH400-W and LXV-3LINH400-W illuminate the same metallic cylinder. The 4LINH image makes the marked surface defects more distinct against the background.
Choose length, colour and control from the inspection geometry
Standard models cover emitting lengths from 100 to 1000 mm. Longer and special configurations should be confirmed as project-specific designs rather than treated as standard dimensions.
- 1
Cover the required field of view
Select an emitting length that covers the inspected line with allowance for alignment and edge fall-off.
- 2
Select the colour for contrast
The model code supports R, G, B, W, IR and UV. Test wavelength choice against the material, coating and defect.
- 3
Set the working distance
Balance mechanical clearance with the measured change in illuminance and emitting width.
- 4
Confirm power and controller
Match the selected length and colour to the voltage, power and compatible high-power constant-voltage or constant-current controller.

4 m continuous-emitting line-scan example
The standard light-parameter table states a maximum 5 m customization remark. A separate customized-series example documents the 4 m model below and states that the ultra-long construction can reach 6 m. Treat lengths beyond the standard 100–1000 mm range as project-specific engineering, not standard catalogue sizes.

Mount rigidly, keep airflow clear and align the light line
The housing uses M4 nut slots and fixing plates. Fan cooling is part of the design, so installation space must not obstruct airflow or place the light where heat accumulates.
Check housing, connector and emitting-area dimensions
Models 100–400 and 500–1000 use different connector arrangements in the dimensional drawings. The detailed model table below provides voltage, power, weight and controller matching data.
