Abstract:
1. A light emitting device comprising: a laser device which generates excitation light; a light emitting section from which light is emitted in response to the excitation light; and a light guide irradiation member, having one end and the other end, which guides the excitation light, having entered via the one end, toward the other end and irradiates a predetermined light irradiation area of the light emitting section with the excitation light thus guided, the other end having a cross-sectional area which is smaller than that of the one end, so that the light guide irradiation member prevents an irradiation range of the excitation light from becoming larger than the size of the light emitting section, a luminance of the light emitting section being larger than 75 cd/mm the light emitting section emitting the light with a luminous flux of more than 2000 lm.
