Abstract:
1. An electronic device comprising: a flexible substrate; a first conductive trace disposed on and affixed to a first surface of the substrate, the first conductive trace comprising (i) a first end of the first conductive trace, (ii) a second end of the first conductive trace opposite the first end of the first conductive trace, and (iii) disposed between the first end of the first conductive trace and the second end of the first conductive trace, a first serpentine section of the first conductive trace extending along a serpentine path; extending substantially collinearly with the first conductive trace, a second conductive trace disposed on and affixed to the first surface of the substrate, the second conductive trace comprising (i) a first end of the second conductive trace, (ii) a second end of the second conductive trace opposite the first end of the second conductive trace, and (iii) disposed between the first end of the second conductive trace and the second end of the second conductive trace, a first serpentine section of the second conductive trace extending along a serpentine path; extending substantially collinearly with the first and second conductive traces, a third conductive trace disposed on and affixed to the first surface of the substrate, the third conductive trace comprising (i) a first end of the third conductive trace, (ii) a second end of the third conductive trace opposite the first end of the third conductive trace, and (iii) disposed between the first end of the third conductive trace and the second end of the third conductive trace, a first serpentine section of the third conductive trace extending along a serpentine path; a first light-emitting element having first and second distinct contacts on a first surface of the first light-emitting element, the first and second contacts being attached to and in electrical contact with, respectively, the first end of the first conductive trace and the second end of the second conductive trace; and a second light-emitting element (i) electrically connected in series with the first light-emitting element, and (ii) having third and fourth distinct contacts on a first surface of the second light-emitting element, the third and fourth contacts being attached to and in electrical contact with, respectively, the first end of the second conductive trace and the second end of the third conductive trace, wherein: the first end of the first conductive trace comprises a plurality of spaced-apart protrusions, the second end of the first conductive trace comprises a plurality of spaced-apart protrusions, and a length of the protrusions of the first end of the first conductive trace is greater than a length of the protrusions of the second end of the first conductive trace.
