Title:
LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/074340
Kind Code:
A1
Abstract:
Provided is a lighting device that can easily select and emit light having a specific wave length. Specifically, this lightning device is provided with: a light source unit that outputs light having a specific wavelength; an illumination unit that emits light output from the light source unit: and a light guiding path part that connects the light source unit and the illumination unit. The lighting device is configured such that: the light guiding path part has light-source-side optical fiber wires which are connected to the light source unit and which enable transmission of light output from the light source unit, illumination-side fiber wires which are connected to the illumination unit and which enable transmission of light to the illumination unit, and a guide connection part for connecting between the light-source-side optical fiber wires and the illumination-side fiber wires; the light source unit is formed so as to be able to selectively output light having different wavelengths; in the guide connection part, the light-source-side optical fiber wires are held in a collective state, and the collectively held light-source-side optical fiber wires and the illumination-side fiber wires are held in a state of facing each other; and by changing the wavelength at the light source unit, selected light is emitted from the illumination unit.
