| 英文摘要 | A headlamp 1 includes: laser diodes 2 that emit excitation light; and a light emitting part 5 that emits light upon receiving the excitation light emitted from the laser diodes 2, the light emitting part 5 containing a first fluorescent material and a second fluorescent material, the first fluorescent material having its emission spectrum peak in a range of not less than 500 nm but not more than 520 nm, the second fluorescent material having an emission spectrum peak which is different from the emission spectrum peak of the first fluorescent material. In a spectrum of the light emitted from the light emitting part 5, a luminous intensity at the emission spectrum peak of the first fluorescent material is higher than a luminous intensity in an emission spectrum covering a range of not less than 540 nm but not more than 570 nm. This allows the headlamp 1 to emit illumination light which achieves a high visibility of an irradiation target at least in a dark place. |
