  • Publication number: 20230125470
    Abstract: Photoluminescence generated by excitation light emitted from an excitation light source can be effectively utilized. A vehicle lamp according to the present invention includes a lamp housing and a lamp lens forming a lamp chamber, an excitation light source disposed in the lamp chamber and emitting excitation light, and a luminescence unit fixed to the lamp lens on a side thereof closer to the lamp chamber and generating photoluminescence by the excitation light emitted from the excitation light source. The lamp lens is a lens that transmits the photoluminescence generated in the luminescence unit and emits the photoluminescence outside the lamp chamber. As a result, the present invention enables effective use of the photoluminescence generated by the excitation light emitted from the excitation light source.
