Abstract: An integrated LED light-emitting device includes: at least two mutually-isolated LED light-emitting epitaxial units having an upper and a lower surface, in which, the upper surface is a light-emitting surface; an electrode pad layer over the lower surface of the LED light-emitting epitaxial unit, with sufficient thickness for supporting the LED epitaxial unit and connecting to each LED light-emitting epitaxial unit to form a connection circuit plane with no height difference; and the electrode pad layer is divided into a P electrode region and an N electrode region. The LED light-emitting epitaxial units constitute a series, parallel or series-parallel circuit. Embodiments disclosed herein can effectively improve the problems of package welding, electrode shading and poor wiring stability.

Abstract: An electrode structure for effectively improving the stability of a semiconductor LED includes a reflecting layer capable of current spreading. In such an electrode structure, the current injects from the side surface of the reflecting layer to form a certain potential gradient over the contact surface between the electrode and the LED contact surface, thereby inhibiting the metal ion of the reflecting layer from migration due to electric field during usage, thereby improving device stability. In addition, the electrode portion for current injection can include a high-reflectivity material yet not vulnerable to ion migration, thereby increasing the entire reflecting area and improving luminous efficiency.
