LIGHT-EMITTING ELEMENT REPAIR IN ARRAY-BASED LIGHTING DEVICES

摘要

In accordance with certain embodiments, patches with replacement light-emitting elements thereon are utilized to repair lighting-system fault locations.

主权项

1. A lighting system comprising:
a substrate; disposed on the substrate, a plurality of spaced-apart conductive traces defining a plurality of gaps therebetween; a plurality of light-emitting elements disposed over the substrate, each light-emitting element being disposed within a gap and electrically connected to the conductive traces defining the gap; a fault location defined by a gap between two conductive traces either (i) lacking a light-emitting element therein or (ii) comprising an inoperative light-emitting element therein; and disposed over or under the substrate at the fault location, a patch comprising (i) a patch substrate, (ii) two conductive traces disposed on the patch substrate, and (iii) a replacement light-emitting element electrically coupled to the two conductive traces of the patch, wherein the conductive traces of the patch are each electrically connected to one of the conductive traces defining the fault location, thereby electrically connecting the replacement light-emitting element across the fault location.
