Abstract:
A light-emitting device can include a fluorescent plate having a first surface and a second surface opposite to the first surface and configured to emit fluorescent light by laser irradiation. A first laser light source can be disposed such that the first surface of the fluorescent plate is irradiated with first laser light. A second laser light source can be disposed such that the second surface of the fluorescent plate is irradiated with second laser light. A reflector can include a light passing hole through which the second laser light can pass and can include a concave reflecting surface configured to cover an irradiation region with the second laser light at least on the fluorescent plate. A lens can be disposed in a space closer to the first surface of the fluorescent plate.
