PURPOSE: A lens and a light emitting device including the same are provided to improve a chromatic aberration phenomenon, thereby reducing a yellow spot or ring phenomenon due to chromatic aberration. CONSTITUTION: A first lens part(310) is arranged on the upper part of a light emitting diode chip. A second lens part(320) is arranged on the upper part of the first lens part. The upper surface of the first lens part has a concave shape. The lower surface of the second lens part has a convex shape. The outline of a total lens in which the first lens part and the second lens part are combined has a hemispherical shape. A chip protection part(330) is arranged into one body with the first lens part. The chip protection part covers the light emitting diode chip and a bonding wire electrically connected to an electrode arranged on the upper surface of the light emitting diode chip. |
