Abstract
A light emitting diode (LED) chip for high voltage operation and an LED package including the same are disclosed. The LED chip includes a substrate, a first array formed on the substrate and including n light emitting cells connected in series, and a second array formed on the substrate and including m (m≦n) light emitting cells connected in series. During operation of the LED chip, the first array and the second array are operated by being connected in reverse parallel to each other. Further, when a driving voltage of the first array is delined as Vd1 and a driving voltage of the second array is defined as Vd2, a difference between Vd1 and Vd2×(n/m) is not more than 2V.
