SURFACE MOUNT LIGHT EMITTING DIODE PACKAGE
A surface mount light emitting diode package (surface mount LED package) includes a leadframe, a LED chip, a plurality of conductors and an encapsulant. The LED chip is disposed over the leadframe. The LED chip has an active surface facing the leadframe and a plurality of electrodes is disposed on the active surface. In addition, the conductors are disposed between the leadframe and the LED chip, the electrodes are electrically connected to the leadframe through the conductors and the encapsulant encapsulates the LED chip and a part of the leadframe. In this way, the surface mount LED package of the present invention has better luminescence efficiency.
