Abstract
An LED package having an MEMS switch operated by electrostatic force, capable of continuously protecting an LED from excessive current due to electrostatic discharge. The LED package includes a submount with first and second electrode patterns formed thereon; an LED mounted on the submount, having an n-electrode electrically connected to the first electrode pattern and a p-electrode electrically connected to the second electrode pattern; and an MEMS switch including a first conductive plate and a second conductive plate bent to have an area over and vertically apart from the first conductive plate, wherein the first and second conductive plates are electrically connected to the first and second electrode patterns, and the second conductive plate comes in contact with the first conductive plate by electrostatic force upon being applied with voltage higher than a predetermined level of voltage.
