  • Lead frame structure of light emitting diode
    Patent number: 7705435
    Abstract: A lead frame structure of a light emitting diode is disclosed. The lead frame structure comprises a bonding zone, two wing-shaped reflective surfaces, a first electrode lead, and a second electrode lead. The first electrode lead and the second electrode lead are respectively connected to the bonding zone. The bonding zone bonds the light emitting diode. The reflective surfaces are formed on both sides of the bonding zone. A predetermined angle is formed between the bonding zone and the wing-shaped reflective surfaces for reflecting the side light emitted from the light emitting diode towards a predetermined direction.
    Type: Grant
