Zusammenfassung:Suggested is a light emitting device mounting an optical unit capable of improving the non-uniformity of brightness and a color by mounting the optical unit on the light emitting device without an alignment error with a simple method. The device includes a light emitting device with a stepped part and the optical unit which has at least one protrusion which is connected to the stepped part of the light emitting device. At this time, the protrusion is connected to the inner side of the stepped part and has a n-polygonal cross section (n>=3). 간단한 방법으로 정렬 오차없이 발광 소자에 장착되어 색상 및 휘도의 불균일성을 개선시킨 광학부가 장착된 발광 소자를 제시한다. 그 소자는 단턱부를 가지는 발광 소자 및 발광 소자의 단턱부에 체결되는 적어도 하나의 돌기가 형성된 광학부를 포함하고, 이때 돌기는 단턱부의 내측에 체결되고, n각형(≥3)의 단면을 이룰 수 있다.
