Abstract
A light emitting diode (LED) package is disclosed. In one embodiment, the LED package includes an LED, which emits light corresponding to an electric signal and a substrate, which is mounted to electrically couple to the LED and has an anode lead frame and a cathode lead frame. The package also includes a voltage regulator diode, which is mounted on the substrate and has a parallel connection with the LED to maintain voltage regulation. The LED package further includes a shielding dam, which is located between the LED and the voltage regulator diode and prevents light emitted by the LED from being directly irradiated to and reflected or absorbed by the voltage regulator diode. In at least one embodiment, the LED package can prevent the light emitted by the LED from being directly absorbed by the voltage regulator diode.
