Abstract
A light emission device 20 comprises a light source 21 irradiating excitation light; and a window glass 13 emitting visible light through incident radiation of the excitation light, which is attached to a car door 10, wherein the window glass 13 emits the light by irradiation with the excitation light depending on an opening/closing state of the car door 10. The present invention can provide a light emission device that enables the opening and closing of a vehicle door to be easily recognized by a person in the back, without attaching any separate part to an outer side of the vehicle door or the like.
