TECHNICAL FIELD The present invention relates to a light emitting diode (LED) package, and more particularly, to an LED package having an array of light emitting cells coupled in series, which can be directly connected to and driven by an AC power source.
BACKGROUND ART Since light emitting diodes (LEDs) can realize colors, they have been widely used for indicating lamps, electric display boards and displays. The LEDs have also been used for general illumination because they can realize white light. Since such LEDs have high efficiency and longer life span and are environment-friendly, their applicable fields have been continuously expanded.
Such an LED lamp is disclosed in U.S. Pat. No. 5,463,280 entitled �LIGHT EMITTING DIODE RETROFIT LAMP� issued to James C. Johnson. The LED lamp includes a plurality of light emitting diodes coupled in series, a means for limiting a current, and a diode bridge. Since an AC current is converted to a DC current through the diode bridge, the LED lamp can be driven by an AC power source.
Technical Problem An object of the present invention is to provide a light emitting diode (LED) package, which can be driven using an AC power source without an external AC/DC converter and thus can be miniaturized.
Technical Solution In order to achieve these objects of the present invention, the present invention provides an LED package having an array of light emitting cells coupled in series. An LED package according to an aspect of the present invention 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 package according to this aspect of the present invention mounts the LED chip having the array of light emitting cells coupled in series thereon, it can be driven directly using an AC power source.
Here, the term �light emitting cell� means a minute LED formed in a single LED chip. Although an LED chip generally has only one LED, the LED chip of the present invention has a plurality of light emitting cells.
An encapsulant and/or a molding member may encapsulate the LED chip. The encapsulant and/or molding member protect the LED chip against moisture or external forces. The terms �encapsulant� and �molding member� herein are used without any differences from each other. However, in some embodiments, they are used together for discriminately referring to components.
Advantageous Effects According to the present invention, it is possible to provide an LED package and an LED lamp, which can be driven using an AC power source without an external AC/DC converter and thus can be miniaturized. Further, since light emitting cells formed on a single substrate are employed, the process of fabricating a package can be simplified and thus is advantageous to mass production. Moreover, since generated heat can be easily dissipated by employing the heat sink, the photometric efficiency of the light emitting cells can be improved. Furthermore, since the heat sink can be prevented from being separated from the package body, it is possible to provide an LED package that is stable in view of its structure.
DESCRIPTION OF DRAWINGS FIGS. 1 and 2 are sectional views illustrating light emitting diode (LED) chips each of which has an array of light emitting cells coupled in series, which are applicable to embodiments of the present invention.
BEST MODE Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the LED chip with first to n-th light emitting cells 100-1 to 100-n coupled in series, as shown in FIG. 1, the P-type pad 90 is formed on the P-type semiconductor layer 60 of the first light emitting cell 100-1, and the N-type semiconductor layer 40 of the first light emitting cell 100-1 and the P-type semiconductor layer 60 of the second light emitting cell 100-2 are connected through a first wire 80-1. Further, the N-type semiconductor layer 40 of the second light emitting cell 100-2 and the P-type semiconductor layer (not shown) of the third light emitting cell (not shown) are connected through a second wire 80-2. An N-type semiconductor layer (not shown) of the (n-2)-th light emitting cell (not shown) and a P-type semiconductor layer 60 of the (n-1)-th light emitting cell 100-n-1 are connected through an (n-2)-th wire 80-n-2, and an N-type semiconductor layer 40 of the (n-1)-th light emitting cell 100-n-1 and a P-type semiconductor layer 60 of the n-th light emitting cell 100-n are connected through an (n-1)-th wire 80-n-1. Further, the N-type pad 95 is formed on the N-type semiconductor layer 40 of the n-th light emitting cell 100-n. The substrate 20 in the present invention may be a substrate on which a plurality of LED chips can be fabricated. Here, positions designated by �A� as shown in FIGS. 1 and 2 refer to cutting positions for cutting the substrate into discrete LED chips.
Referring to FIG. 6, a first serial array 31 is formed by coupling light emitting cells 31 a, 31 b and 31 c in series, and a second serial array 33 is formed by coupling other light emitting cells 33 a, 33 b and 33 c in series. Here, the term �serial array� refers to an array of a plurality of light emitting cells coupled in series.
