LED panels and substrates: reveal the repeated pattern without implying electrical performance
Two independent source captures show a dense lamp-panel array and a larger substrate pattern. Flat coaxial lighting makes the repeated geometry visible for an appearance trial; the images do not establish whether the devices light or conduct correctly.
Use the pattern for appearance checks and verify device function independently.

Explore it in 3D
Camera and available lens CAD are published models. Lens and light envelopes use printed dimensions. The linked station uses its published base size and column height; carriage, brackets, fittings, parts and spacing are illustrative. Confirm load, travel, fasteners and clearances before ordering. Light paths explain the arrangement and do not simulate optical performance. Representative part geometry is illustrative, not reconstructed inspection evidence. The specimen and lighting angle are representative, not dimensions or settings recovered from the source capture.
Lighting application-lab catalog capture
What the camera saw
Cropped from the source test sheet; original test annotations are retained. Captures are not generated or enhanced. Drag a comparison slider, or open any image full size.
The challenge
A large repeated array can hide local missing or malformed features in otherwise similar neighbours.
Surface marks and pattern geometry must be distinguished from actual electrical defects.
How it was solved
The catalog identifies a white 100 mm flat coaxial light for the lamp-panel example and a white 200 mm version for the independent substrate example.
Choose a proposed field that resolves the required repeated feature. The illustrated panel is representative and does not recreate either source sample or prove whole-panel coverage.
Why it works
- 1
A broad light-guide arrangement provides a reflected view of repeated features with a compact light envelope.
- 2
The observed patterns support visual inspection planning, but the source images are not electrical or optical-output tests.
Lighting application-lab catalog capture
Evidence you can inspect
The lamp-panel array and the separate patterned substrate have visible repeated geometry.
The source labels lamp-panel and LED-substrate defect inspection and identifies their respective white flat coaxial lights.
Two different source samples, without labelled individual defects, minimum feature size, detection results or device-function data.
From image contrast to a production decision
What to validate on your part
- 01
Define the visible defect classes
Include missing, displaced and damaged features as well as accepted pattern variation.
- 02
Check the entire planned field
Confirm focus and sampling at corners and centre without inferring the source part scale.
- 03
Retain functional testing
Validate electrical continuity or emitted-light performance separately when required.

Mount the optics with intent
The station is an optical test bench, with its two lighting holders included in the catalog listing. The 3D column and base follow the published height and footprint. Carriages, clamps and part supports are schematic: confirm camera screw pattern, lens support, light fasteners, permissible load and actual travel before ordering.
Complete the electrical system
Select a controller against the exact light voltage, drive mode and power, then confirm camera data/power/I/O cables and a suitable PC. These are not silently added to the proposed optical kit.

Start from this setup, adapt it to your part.
The configurator opens with this study's camera, lens, light and station picked. Swap any part, check fit and price, then buy or ask for a quote.

About this case study: the photos and camera images come from the application laboratory of the maker of the lighting and optics we sell, imaged on the parts shown; your results depend on your part, camera and set-up. This is an application-lab study, not a LumaSpec customer deployment. Source figures are reported results; proposed components require a fresh trial. The 3D scene illustrates the arrangement and does not simulate imaging performance.
