Abstract: Disclosed is a light emitting device having a plurality of light emitting cells and a package having the same mounted thereon. The light emitting device includes a plurality of light emitting cells which are formed on a substrate and each of which has an N-type semiconductor layer and a P-type semiconductor layer located on a portion of the N-type semiconductor layer. The plurality of light emitting cells are bonded to a submount substrate. Accordingly, heat generated from the light emitting cells can be easily dissipated, so that a thermal load on the light emitting device can be reduced. Meanwhile, since the plurality of light emitting cells are electrically connected using connection electrodes or electrode layers formed on the submount substrate, it is possible to provide light emitting cell arrays connected to each other in series. Further, it is possible to provide a light emitting device capable of being directly driven by an AC power source by connecting the serially connected light emitting cell arrays in reverse parallel to each other.

Abstract: An illumination system includes multiple light emitting devices arranged in an area so as to be spaced apart from each other. Each light emitting device includes multiple light emitting diode arrays each of which has one light emitting diode or a plurality of light emitting diodes connected in series. The numbers of the light emitting diodes included in each light emitting diode arrays differs from each other. A controller is configured to establish one or more groups each including one or more light emitting devices and adjust an illumination state of each light emitting device by controlling the driving state of the one or more light emitting diode arrays included in each light emitting device. The controller may select the number of light emitting devices included in each group based on an external condition.
