Lighting device

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 at 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 is formed to extend in a lower direction 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, and
• wherein the light source is composed of a light source package that comprises:
• a package body having a cavity;
• a first lead frame including one end exposed to the cavity, and another end exposed to one surface of the package body by passing through the package body;
• a second lead frame including one end exposed to one side of the one surface of the package body, another end exposed to another side of the one surface of the package body, and a middle part exposed to the cavity;
• and at least one light emitting chip disposed on a first semiconductor layer, an active layer, a second semiconductor layer and the first lead frame.
