UZ Jette has announced in the media they will expand their surgical facility. This Ph.D. develops an innovative light- and ventilation-design to reduce post-operative infections and an will be installed at this new facility. When you undergo surgery, there is still about 4% chance you will develop a post-operative infection, which will lead to discomfort, increased costs for health care and possibly hospital re-admission. One of the measures to reduce infection rate is a laminar downflow, i.e. clean, cooled air, that descends on the patient from the plenum. However, this laminar flow is perturbed by the surgical luminaire. Post-operative infections originate as airborne pathogenic particles enter the surgical site by turbulent air flows. To reduce or even eliminate this disturbance of the laminar air-flow by the surgical lighting, we propose an integrated concept of an LED-based light source with a laminar down-flow system. The luminaire will no longer be a mechanical obstruction to the air flow, due to the integration. Also, turbulences due to thermal effects are reduced, as the heat produced in the light source can be cooled and there is less radiation-heat in LED lighting. This integrated concept will be installed in an experimental operating room at the renewed surgical facility at UZ Jette.
