Lighting apparatus having an optical module with a half-mirror member

A lighting apparatus comprising:

• a light source module including an optical member configured to guide light emitted by a light emitting unit to implement surface light emission;
• and
• an optical module disposed above the light source module;
• wherein a half-mirror member of the optical module transmits some light emitted by the light source module and reflects the remaining light toward the light source module, wherein the number of light source modules, which are identical to the light source module, is two or more, and a diffusion member, which is disposed to form an inclination angle with respect to an extension line formed by a bottom surface of the half-mirror member, is further included in the lighting apparatus.
