Title:
LIGHTING DEVICE
Document Type and Number:
Japanese Patent JP2023067375
Kind Code:
A
Abstract:
To provide a lighting device capable of easily selecting and radiating light of a specific wavelength.SOLUTION: A lighting device includes a light source unit for outputting light of a specific wavelength, a lighting unit for radiating light output from the light source unit, and a light guide unit for connecting the light source unit and the lighting unit. The light guide path includes a light-source-side optical fiber wire which is connected to the light source unit and transmits light output from the light source unit, a light-side optical fiber wire which is connected to the lighting unit and transmits light to the lighting unit, and a guide connection unit for connecting a light-source-side optical fiber wire and the lighting-side optical fiber wire. The light source unit is formed so as to be capable of selectively outputting light of different wavelengths, and configured so that the light-source-side optical fiber wires are held to be aggregated with one another in the guide connection unit, the aggregated and held optical fiber wires on the light source side and the lighting-side optical fiber wires are held to face each other, and light selected from the lighting unit is radiated by switching the wavelength of the light source unit.SELECTED DRAWING: Figure 1
