Patent number: 7963674Abstract: A light emitting diode package comprising a substrate electrically connectable to an external unit with a reduced height. A flexible PCB for electrical connection between a light emitting diode and the external unit is directly connected to a light emitting element. The direct connection is conducted by applying a conductive resin to an electrode on the flexible PCB, on which the light emitting element is mounted; mounting the light emitting element; curing the conductive resin in a high-temperature furnace. The present invention requires neither a lead frame for electrical connection of the light emitting element to the flexible PCB nor a rigid PCB for supporting the flexible PCB, thus reducing the total height of the light emitting diode package.Type: GrantFiled: October 24, 2007Date of Patent: June 21, 2011Assignee: Avago Technologies ECBU IP (Singapore) Pte. Ltd.Inventors: Akira Takekuma, Chew Tong Fatt
