Conventional LED red reflex illumination technology offers surgeons optimal views of the eye’s structure and texture. However, the quality of red reflex illumination provided by conventional light technology decreases during the most crucial phases of ophthalmic surgery. For this reason, a leading microscopy manufacturer contracted the MOEMS MOEMS (Micro Opto Electronic Mechanical Systems) facility at ESCATEC in Heerbrugg, Switzerland, to design and produce a new red reflex LED light source solution. The MOEMS facility at ESCATEC quickly developed a new high efficiency LED module solution with four individual beam paths to overcome the drawbacks of conventional illumination technology to enable consistent, high quality, detailed ophthalmic views throughout the entire surgical procedure.

LED-generated heat challenges solved through thermal management

Using a high resolution thermal simulation tool developed largely by the University of Vienna, realistic thermal simulation models were quickly generated and optimized from complex structures. After the quality and consistency of the light source were optimised, a back-end cooling system to prevent overheating was also designed and manufactured. The light module’s micro-assembly, thermal management assembly, packaging, and testing were all completed at the cutting-edge MOEMS facility at ESCATEC Switzerland.

“For almost every LED application, heat is the major enemy. Thermal management is a challenge for every LED and LASER device designer and is where ESCATEC in Heerbrugg, Switzerland were able to develop a specific solution” says Wolfgang Plank, head of the MOEMS facility, “Our customers wanted the higher performance of LED lights with lower service costs as an alternative to previous Xenon technology. Our extensive experience with LEDs enabled us to quickly deliver the right solution.”
