Abstract

LED technology offers significant advantages over halogen and arc lamps in medical imaging due to long lifetimes, ruggedness and potential efficiency. However, LEDs have limitations, limited irradiance and efficiency degradation. Luminescent Concentrators (LCs) present a promising solution as they benefit from LEDs strengths whilst providing high theoretical efficiencies, brightness and generation of new wavelength components. This work introduces a novel approach of achieving a white light source using LED-pumped LCs. By combining various fluorophores, LCs can emit an optimal spectral output for multispectral applications such as endoscopy. The performance of this white light source is evaluated against traditional methods, xenon and halogen lamps, proving its potential as a replacement for aging technologies in medical imaging.
