Abstract:
An illumination device 1 which is a light emitting device capable of emitting white light, includes: a laser element 2 for emitting a blue laser beam; a light emitting section 4 for generating fluorescence by be being irradiated with the blue laser beam emitted from the laser element 2; and a parabolic mirror 5 for reflecting the fluorescence generated from the light emitting section 4, the parabolic mirror 5 being disposed on an irradiated surface side which irradiated surface is a surface of the light emitting section 4 which surface is irradiated with the blue laser beam. This allows the illumination device 1 to efficiently project the white illumination light.
