A light emitting device may comprise a wing portion of an electrode exposed from the resin housing. The wing portion may be made by a single or multiple stamp cutting process. To increase the connecting region between the electrode and solder, the outer side surface of the wing portion is an uneven surface. The device may further comprise a protective plating layer and an external protective plating layer. The protective plating layer may be coated on the top surface, bottom surface and a portion of the side surface of the electrode. The external portative plating layer would be coated on the outer surface of the wing region. The light reflection of the device from top surface of the electrode portion can be maintained and the outer side surface of wing portion can be protected for improving the reliability of connection between light emitting device and outer substrate.
