Abstract:
A light-emitting diode has a metal structure, a light-emitting chip, and a bowl structure. The metal structure has a platform and a heat sink. The platform has a top face, a first side, and a second side opposite to the first side. A first reflector and a second reflector respectively extend from the first side and the second side. The heat sink extends below the top face and has a drop from the bottom surfaces of the first reflector and the second reflector. The light-emitting chip is disposed on the top face. The bowl structure covers the outer surface of the metal structure and shields the bottom surfaces of the first reflector and the second reflector. A thermal dispassion surface of the heat sink is exposed from the bowl structure. An inner surface of bowl wall has a plurality of reflection structures to promote the light extraction efficiency.
