Abstract
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 formed on the light source module, and a side wall which is integrally formed with the upper surface and which is adhered onto an outer side surface of the indirect light emission unit, wherein a first separated space is formed between the light source module and the upper surface of the diffusion plate, whereby flexibility of the product itself can be secured, and durability and reliability of the product can be also improved while indirect light emission using a flare effect can be implemented.
