C10970: Compact LED Endoscopic Illumination SystemNovelty:
A novel compact LED endoscopic illumination system that uses a lower power LEDs that can be integrated into many systems.
Value Proposition:
Coupling light at a high efficiency into an endoscopic fiber is difficult, especially for a small gauge light pipe where the coupling efficiency is usually no more than a few percent. The developed system allows a high coupling efficiency in the order to tens of percent, which reduces the requirement for the use of ultra high power LEDs. Advantages that stand out about this invention:
• This will also reduce the overall cost of an illumination system greatly.
• This invention not only maintains the high efficiency for a large diameter fiber but also gives a relatively high efficiency for small diameter light pipe.
• This system can be integrated into other systems, such as video microscope system, to provide high level illumination.
Technical Details:
Johns Hopkins researchers have developed a simple, cost-effective and highly efficient endoscopic illumination system using multi-spectrum LEDs. The system developed uses an elliptical mirrored cavity to mix and couple the LED lights to an endoscopic fiber optic illuminator at a high efficiency. The output light spectrum can be either manually toned or computer-controlled. The illumination system improves the coupling efficiency with LED sources, reducing the cost associated with high-power LED light sources and endoscopes light sources.
Looking for Partners:
