<p>PURPOSE: A heat conducting slug having multi-step structure and a light emitting diode package using the same are provided to prevent the separation of a heat transmission slug from housing by combining support leads or the lead terminals with the heat transmission slug. CONSTITUTION: In a device, a heat transmission slug of a multi level structure includes a first slug(110), a second slug(120), and a third slug(130). The second slug is arranged on the first slug, and the third slug is arranged on the second slug. A first slug having the form of a cylinder is installed within the light-emitting diode package having a circular shape. The second slug and the third slug are arranged to be 45 crossly in order to maximize a heat emitting effect. A light emitting diode(10) is installed within the third slug.</p> |
