Light emitting device package and lighting device having the same

A lighting device comprising:

• a housing having an electrical connection structure;
• and
• at least one light emitting device package mounted in the housing,
• wherein the at least one light emitting device package comprises:
• a reflective unit having a first surface and a second surface opposing the first surface and having a through hole formed in a central portion of the reflective unit to penetrate through the first and second surfaces;
• a light emitting device disposed in the through hole and externally exposed to one of the first and second surfaces;
• and
• an optical device disposed on the first surface of the reflective unit to cover the light emitting device,
• wherein the optical device allows light generated by the light emitting device to be partially transmitted and be partially reflected to be emitted externally.
