Quality Assessment of Virtual Prototypes of Surgical Luminaires using Near-field Ray-data

摘要

Abstract—Surgical luminaires are an important tool for the surgeon, yetnhighlighting the wound of a patient is not trivial and surgical luminairesnmust meet stringent regulatory requirements. Optical requirements andnperformance indicators are described in the European Standard fornsurgical luminaires and they must be measured after construction.nSurgeons and hospital managers often use these performancenindicators to compare different surgical luminaires. The introduction ofnsolid-state lighting and high-power light emitting diodes (LEDs) hasninitiated a new generation of surgical luminaires. When designing anvirtual prototype of a surgical luminaire it would be beneficial to have ancost- and time-effective method to test luminaires for compliance withnthe European Standard. Unfortunately, far-field intensities do not allownan evaluation of these luminaires with respect to the standard andnnear-field ray-data must be used.
