PURPOSE: A light emitting diode is provided to efficiently discharge heat of a light emitting chip by using a heat sink with a reflection structure. CONSTITUTION: A heat sink is combined with a housing(25) and is exposed to the outside through the bottom of the housing. A light emitting chip(10) is mounted on the heat sink. A molding unit(60) is formed on the upper side of the light emitting chip to protect the light emitting chip. The heat sink includes a reflection unit and an upper part. The reflection unit receives the light emitting chip. The upper part is extended from the upper side of the reflection unit in a lateral direction and is overlapped with a part of the housing. The bottom of the heat sink and the bottom of the housing form the same plane. |
