Abstract
A method of making a substantially monolithic lighting device comprising serially connected LEDs and lighting systems including the same. The serially connected LEDs may be comprised in a monolithic device comprising a first LED, a layer of conductive material, and a second LED positioned thereupon. The serially connected LEDs may also be electrically coupled to a plurality of resistors obviating the necessity of an AC/DC power converter when a luminaire containing the serially connected LEDs is connected to an AC power source.
