A method of manufacturing an oxynitride phosphor is revealed. A precursor is sintered under 0.1-1000 MPa nitrogen pressure for synthesis of an oxynitride phosphor. The general formula of the oxynitride phosphors is BaSiON:EuBaSiON:Euor BaSiON:Eu(0.00001&#x2266;x&#x2266;5; 0.00001). Thus pure phosphor can be mass-produced.

A method for manufacturing light emitting device is provided. Firstly, provide a substrate. Then arrange a light emitting unit on the substrate. Next form at least one electrode and arrange at least one protective layer on the electrode. The protective layer is to prevent a phosphor layer following formed on the light emitting unit from covering the electrode. After forming the phosphor layer, flatten the phosphor layer and the protective layer. A part of the phosphor layer over the protective layer is removed. Thus the electrode is not affected by the phosphor layer and conductivity of the electrode is improved to resolve phosphor thickness and uniformity problems of the light emitting device. Therefore, the thickness of the light emitting device with LED is effectively reduced and stability of white color temperature control is significantly improved.

Abstract of Disclosure A light emitting diode includes a substrate, an N-doped layer disposed on the substrate, a plurality of cathodes disposed between the N-doped layer and the substrate, an active layer disposed on the N-doped layer, a P-doped layer disposed on the active layer, and a plurality of anodes disposed on the P-doped layer. The cathodes are electrically connected to the N-doped layer, and the patterns of the cathodes are disconnected from each other. The anodes are electrically connected to the P-doped layer, and the patterns of the anodes are disconnected from each other. Each cathode and a corresponding anode form a loop, and each loop is an independent loop.
