Abstract

In accordance with an aspect of the present inventive subject matter, a lighting device includes light-emitting elements that are mounted in a circular mounting area to be directed in a same direction in the circular mounting area between a first connecting electrode and a second connecting electrode disposed on a substrate, the light-emitting elements are divided into groups each including the same number of light-emitting elements, the light-emitting elements within each group are electrically connected in series with one another by metallic wires and electrically connected in series to the first connecting electrode and to the second connecting electrode. The groups each include the same number of light-emitting elements that are electrically connected in parallel between the first connecting electrode and the second connecting electrode. As another aspect of the present inventive subject matter, a method of manufacturing a lighting device is disclosed.
