照明装置
Document Type and Number:
Japanese Patent JP7117663
Kind Code:
B2
Abstract:
To provide a luminaire capable of enhancing the dependability of positioning a light source and an optical fiber at the time of assembly.SOLUTION: A luminaire 10 includes a laser light source (a semiconductor laser light source ) 41, a control part 49 (a switching part) for switching between a first light emission mode in which a supply current to the laser light source 41 is controlled to emit laser light L10 (first light) and a second light emission mode in which LED light (second light) having lower light emission intensity than the laser light L10 is emitted, an optical fiber 30 for guiding the laser light L10 emitted by the laser light source 41 or the LED light L20, and a restriction member 52 arranged between the laser light source 41 and the optical fiber 30, the restriction member 52 has an opening part 521 which transmits the laser light L10 emitted from the laser light source 41 in the first light emission mode and interrupts light not overlapped with a first irradiation range (an irradiation range) of the laser light L10, out of the LED light L20 emitted from the laser light source 41 in the second light emission mode.SELECTED DRAWING: Figure 2
