Is It Necessary To Integrate LED Lighting Devices into The Endoscopic Camera Module?

Scenarios Where Selection Is Recommended as a Priority

1. Medical human cavity observation: Closed spaces such as bronchi and bladders have no natural light, and liquid reflection easily causes uneven brightness. Fill lights can evenly illuminate mucosal folds, preventing loss of details in micro-nodules and inflamed areas due to insufficient light.

2. Industrial deep cavity/pipeline inspection: In scenarios like engine cylinders and long food pipelines, light attenuates quickly and oil stains block light. Fill lights can supplement light synchronously with the lens, clearly revealing defects such as scale and colloid bubbles.

3. Scientific research (cultural relic/biological observation): Scenarios like ancient ceramic cracks and insect digestive tracts require low-light protection. Fill lights can be adjusted to low brightness to accurately illuminate targets, avoiding damage to samples while restoring micro-textures.

Scenarios Where Selection Can Be Omitted

1. Dental scanners: Dental clinics are equipped with shadowless lamps, which provide uniform and adjustable brightness. Fill lights would instead easily cause tooth reflection, interfering with texture capture at 720P resolution.

2. Laboratory controlled-light observation: In scenarios like material inspection, external light sources (e.g., microscope ring lights) are already precisely matched to module parameters, offering better stability than integrated fill lights.

3. Shallow cavity/open-space inspection: Scenarios like PCB pin inspection have overhead LED lighting on production lines. Natural light combined with ambient light is sufficient, and the F4.0 aperture already meets imaging needs—fill lights would be a redundant configuration.

Conclusion: Core Criterion for Selection – "Whether Lighting Is Controllable and Sufficient"

1. If the scenario involves closed deep cavities, no natural light, or significant light interference (e.g., oil stains, reflection), selection is recommended: fill lights compensate for insufficient light intake, avoiding detection errors.

2. If the scenario has a dedicated, suitable alternative light source (e.g., shadowless lamps, laboratory lights), selection can be omitted: this prevents image quality issues and cost waste caused by redundant light supplementation.
