Shape-matched arc illumination for PCB, labels, curved parts and mobile-glass contours
LXV-SRN arranges LEDs along a partial ring so the illuminated arc can follow curved or irregular inspection regions more flexibly than a complete ring light. The PDF defines 26 source rows spanning multiple outer diameters, emitting angles and central angles, plus configurable colour, cable, control and installation options.

PCB inspection
Direct the illuminated arc around circular or partly circular PCB regions without flooding the complete field.
Product-label inspection
Aim the arc at printing and labels where shape-specific coverage improves contrast.
Arc-component inspection
Match the outer diameter, emitting angle and central angle to the component curvature.
Mobile-glass contour inspection
Lighten a side edge so its outline separates from the background.
Working-distance behaviour, irradiance distribution and mobile-glass contour result
The source provides an LXV-SRN9045-180-B working-distance curve and relative-irradiance maps at LWD 50 and 100 mm, followed by a complete setup–workpiece–result sequence for LXV-SRN24000-120-W.

Select diameter, emitting angle and central angle as one verified optical geometry
The 26 rows are not scaled versions of one drawing. Keep each model name attached to its own angle, body dimensions, power, weight, common status and drawing number; LXV-SRNH9045-180 is a distinct high-output row.
- 1
Map the required illuminated arc
Identify the contour length, curvature and side that must gain contrast.
- 2
Choose the three encoded geometry values
Match outer diameter, emitting angle and central angle to the target and camera field.
- 3
Choose colour and electrical load
Use the exact R or G/B/W power for the selected 24 V model; UV and IR are custom options.
- 4
Validate the production result
Confirm working distance, field coverage, edge contrast and repeatability with the actual camera, lens and part.
