Lightfield adaptable surgical luminaire concept

Area of Science:

• Biomedical Engineering
• Optical Engineering
• Surgical Technology

Background:

• Current surgical lighting offers fixed illumination patterns, which do not match the variable shapes of wounds and their surroundings.
• Suboptimal lighting can negatively impact visual performance and comfort during surgical procedures.

Purpose of the Study:

• To develop and evaluate a new concept for adaptive surgical lighting using bendable LED strips.
• To investigate design parameters for optimizing shape and light distribution of the adaptive lighting system.

Main Methods:

• Computational modeling was employed to simulate and analyze the effects of design choices (strip shape, LED configuration, power).
• A physical prototype of a luminaire segment was constructed and tested to validate simulation results.
• The system's ability to produce complex light fields of various sizes was assessed.

Main Results:

• The developed system can generate adaptable light fields with complex shapes and adjustable sizes.
• Simulations identified optimal parameters for strip and LED configurations.
• Physical prototype testing confirmed the system's functionality aligns with computational predictions.

Conclusions:

• The bendable LED strip lighting system shows promise for improving surgical illumination by adapting to wound characteristics.
• Further development of a real-time, low-effort control system is expected to enhance operating room lighting significantly.
