摘要:
A circuit board for a light emitting diode package improved in heat radiation efficiency and a manufacturing method thereof. In a simple manufacturing process, insulating layers are formed by anodizing on a portion of a thermally conductive board body and plated with a conductive material. In the light emitting diode package, a board body is made of a thermally conductive metal. Insulating oxidation layers are formed at a pair of opposing edges of the board body. First conductive patterns are formed on the insulating oxidation layers, respectively. Also, second conductive patterns are formed in contact with the board body at a predetermined distance from the first conductive patterns, respectively. The light emitting diode package ensures heat generated from the light emitting diode to radiate faster and more effectively. Additionally, the insulating layers are formed integral with the board body by anodizing, thus enhancing productivity and durance.
