Abstract
In various embodiments, lighting systems include an electrically insulating carrier having a plurality of conductive elements disposed thereon, a light-emitting array, and at least one power source. The light-emitting array is disposed over the carrier and includes a plurality of light-emitting strings, each light-emitting string comprising a plurality of unpackaged light-emitting diode (LED) dies electrically connected in series. Each LED die has at least two electrical contacts on one surface thereof, and each electrical contact is electrically connected to a conductive element by a conductive adhesive. The power source provides power to the light-emitting strings.
