Document Type and Number:
Japanese Patent JP2023111426
Kind Code:
A
Abstract:
To provide a vehicular lighting fixture.SOLUTION: A vehicular lighting fixture comprises: a lamp housing 2 and a lamp lens 3 which form a lamp chamber 23; an excitation light source 40 which is arranged in the lamp chamber 23 and emits excitation light L1; a light-emission panel 50 which is arranged in the lamp chamber 23 and excited with the excitation light L1 to emit secondary light L2 for light emission; and a wavelength-selective reflection member 6 which is arranged in the lamp chamber 23, and reflects light having the wavelength of the excitation light L1 and transmits light having the wavelength of the secondary light L2. The wavelength-selective reflection member 6 reflects at least part of excitation-inoperative excitation light L11, not operating to excite the light-emission panel 50, of the excitation light L1 as reusable excitation reflected light L12 to the side of the light-emission panel 50.SELECTED DRAWING: Figure 3
