Abstract
Disclosed is a light emitting diode (LED) package having an array of light emitting cells coupled in series. The LED package comprises a package body and an LED chip mounted on the package body. The LED chip has an array of light emitting cells coupled in series. Since the LED chip having the array of light emitting cells coupled in series is mounted on the LED package, it can be driven directly using an AC power source.
Claims19
A light emitting diode (LED), comprising:
- a package body;
- a submount comprising a plurality of recesses and protrusions and electrode patterns being formed corresponding to each recess and protrusion of the submount;
- and
- light emitting cells bonded to the respective electrode patterns of the submount to couple one another in series according to the recess and the protrusion of the electrode patterns,
- wherein each of the light emitting cells comprises a first-type semiconductor layer and a second-type semiconductor layer interposed between a portion of the first-type semiconductor layer and the electrode patterns, and
- wherein the submount is interposed between the light emitting cells and the package body.
