发明名称 Lighting device
摘要 Provided is a lighting device, comprising: a light source module comprising: at least one light source disposed on a printed circuit board; and a resin layer disposed on the printed circuit board so that the light source is embedded; an indirect light emission unit which is formed in at least any one of one side and another side of the light source module and which reflects light irradiated from the light source; and a diffusion plate having an upper surface which is in contact with an upper part of the light source module, and a side wall which is integrally formed with the upper surface and formed to extend in a lower side direction and which is adhered onto an outer side surface of the indirect light emission unit, whereby flexibility of the product itself can be secured, and durability and reliability thereof can be also improved.

主权项 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.
