Can The Endoscope Camera Module Be Equipped with Both LED Beads And Optical Fiber Supplementary Lighting Simultaneously?

Currently, the endoscope camera module can be equipped with both ‌LED beads and fiber supplementary lighting ‌. This composite design combines the advantages of both light sources to adapt to more complex inspection environments and improve imaging quality. The following are the key bases and technical features:

1. Youdaoplaceholder0 Technical feasibility is clear ‌

Structural design support: ‌ There is a dedicated design scheme in which LED beads and fiber optic light guide columns ‌ are arranged simultaneously on the head end seat (the area above the probe) of the module and on both sides of the lens ‌. The LED beads are directly installed on the PCBA board, while the optical fiber light guide column is located directly above the LED beads to conduct the light from the external light source. This physical layout ensures that the two light sources can coexist and work together.

Functional complementarity: ‌ LED light source (front illumination) and fiber optic light guide (conduction of high brightness, uniform external light source illumination) are functionally complementary and there is no technical exclusion problem.

2. Youdaoplaceholder0 Advantages of composite light source ‌

Close-range brightness controllable (LED) : ‌ LED beads closely attached to the inspected object provide direct, close-range point light source illumination with low path loss, making it easy to control close-range brightness and direction, especially suitable for observing surface details or small structures.

Long-distance/deep cavity uniform brightener (fiber) : ‌ High-power external light sources conducted by fiber (such as brightener boxes) provide much stronger, more uniform illumination than ordinary leds. This is crucial for scenarios that require deep penetration into the interior of the cavity, illuminating a large area, or extremely uniform and shadowless illumination.

Enhanced flexibility: ‌ integrates two light sources on the same module, significantly improving the device 's ability to handle different inspection scenarios (e.g. Narrow range exploration vs.) The adaptability and lighting effect of deep cavity long-distance wide-range observation.

Redundancy and reliability improvement: ‌ In some critical applications, the dual-light source design provides some lighting redundancy and increases system reliability.

3. Youdaoplaceholder0 Implementation method and application considerations ‌

Space layout: ‌ The design difficulty lies in the reasonable arrangement of the lens, LED beads, fiber optic light guide column and corresponding circuits and optical paths within the limited probe space (especially the ultra-thin diameter module) to ensure non-interference and structural stability.

Optical path control and fusion: ‌ requires careful optical design, reasonable distribution and fusion of light from two sources, avoiding mutual interference (such as glare caused by the reflection of LED light by the fiber light guide column) or the formation of non-uniform light spots. It may involve the optimization of the shape of the light guide column, the shading structure, the intelligent light stress node algorithm, etc.

Cost and complexity: ‌ Compared with a single light source solution, integrating LED and fiber fill light simultaneously increases module complexity, manufacturing cost, and maintenance cost. Optical fiber light sources themselves are relatively expensive and their maintenance is relatively complex.

Application-driven: ‌ This design is typically found in high-end industrial endoscopes or specific medical endoscopes that have very high requirements for ‌ lighting performance and adaptability ‌, to meet the complex and changing inspection requirements.

Conclusion

The endoscope camera module can and already has ‌ combined supplementary lighting design with LED beads (direct illumination) and fiber optic light guide (conducting external light source illumination) ‌. This design significantly enhances the imaging capability and adaptability of the endoscope in complex and variable environments by combining the advantages of LED short-range controllable lighting and fiber optic transmission for long-distance high-brightness and uniform lighting. It is an effective technical solution to meet the demands of high-end inspection. The key to its realization lies in precise spatial layout, optical path control, and balancing cost and performance requirements.
