PURPOSE: An LED package including a multilens is provided to easily form an optical axis by forming a first lens as an asymmetric lens. CONSTITUTION: A light emitting device (200) includes a light emitting part. A first lens part (300) refracts light. A second lens part (400) surrounds the first lens part. The refractive index of the second lens part is different from the refractive index of the first lens part. A multilens is an asymmetric lens. |
