Abstract
There is provided a light source module including a light emitting device, and an optical device including a first surface disposed above the light emitting device and having a hollow recessed in a light emitting direction in a central portion through which an optical axis passes, and a second surface disposed to be opposite to the first surface and configured to refract light incident through the hollow to be emitted to the outside. The optical device includes a plurality of ridges disposed on the second surface and periodically arranged in a direction from the optical axis to an edge connected to the first surface.
