摘要:
The general domain of the invention is that of lighting devices comprising two fibre light sources (SF) and a light bundle comprising a plurality of second multimode optical fibres. These devices are intended to be mounted in perioperative optical probes that require perfectly homogeneous visible light and fluorescent light. In a first embodiment, the lighting device comprises: a single lens disposed between the fibre sources and the inlet of the bundle; and an optical diffuser. In a second embodiment, the lighting device comprises: an afocal system (L1, L2) disposed between the fibre sources and the inlet of the bundle; and an optical diffuser (D). An optical fibre coupler or a semi-reflecting blade is used to mix two fibre sources.
