PROBLEM TO BE SOLVED: To improve eye safety by controlling an optical path of reflection light while preventing enlargement of a device in a reflection type light emitting module in which excitation light and a fluorescent member are combined.SOLUTION: Excitation light from a solid light source 2 is incident on a light emitting module 10, and the light emitting module 10 emits light with wavelength different from that of the excitation light. The light emitting module 10 comprises: a substrate 11; a light emitting body 12 one part of which is embedded in the substrate 11 and that receives the excitation light and emits light; and a reflection face 13 provided on a contact face of the substrate and the light emitting body. At least one of the reflection face 13 and the light emitting body 12 is provided with a retroreflection structure. The light emitting body 12 is, for example, a spherical body. |
