An optical structure includes a body facing a light emitting surface of a light emitting diode package and including a portion protruding toward the light emitting surface of the light emitting diode package, where a surface of the protruding portion faces the light emitting surface and forms a reflective surface of the optical structure; and a leg elongated from a periphery of the body toward the point light source, where the leg supports the body to be spaced apart from the light emitting diode package.
