PROBLEM TO BE SOLVED: To provide a flat lamp that can emit light by better-defined behavior.SOLUTION: A lamp for emitting light includes a nearly flat-shaped transparent light guide having at least one light-receiving side, a light-emitting front face and a rear face which faces the light-emitting front face and has a plurality of optical extraction structures, and a plurality of light sources which are located in an array shape and are optically connected to at least one light-receiving side. A light scattering structure does not exist in a light path of the light emitted by the lamp. |
