Patent ID: 7504272

Claim:
A method for producing a color-converting light-emitting device, comprising: providing a light-emitting device having an electrode and a semiconductor light-emitting element; providing an electrodeposition apparatus including an anode, an auxiliary cathode, a solution that has light-color converting material particles dispersed therein, and a processing tank configured to accommodate the anode, the auxiliary cathode and the solution; placing the light-emitting device in the solution such that the anode and the light-emitting device are opposite to each other, and such that the auxiliary cathode is interposed between the light-emitting device and the anode; electrically connecting the electrode of the light-emitting device to the auxiliary cathode; and applying a DC voltage between the electrode and the anode so that an electrical potential of the electrode and the auxiliary cathode is lower than an electrical potential of the anode so as to cause the light-color converting material particles in the solution to migrate to the semiconductor light-emitting element and deposit on a surface of the semiconductor light-emitting element.
