Claim:
1. A lighting device comprising: a light source module comprising a plurality of light sources on a printed circuit board, and a resin layer on the printed circuit board so that the plurality of light sources are embedded; an indirect light emission unit formed in at least one side of the light source module and reflecting a light irradiated from the plurality of light sources; and a diffusion plate having an underside of an upper surface, the underside being in contact with an upper part of the light source module, and a side wall integrally formed with the upper surface and formed to extend in a lower side direction; wherein the indirect light emission unit comprises: a light reflection member disposed on an inner side of the side wall of the diffusion plate, and an indirect light-emission separated space formed between the light source module and the light reflection member; wherein the light reflection member faces a side surface of the resin layer and a side surface of the printed circuit board, and wherein a light emitted from the resin layer to the indirect light-emission separated space is scattered in the indirect light-emission separated space.
