1. A lighting system comprising:
- a substantially planar flexible substrate having a first surface and a second surface opposite the first surface;
first and second spaced-apart power conductors disposed over the first surface of the substrate;
a plurality of light-emitting strings forming a two-dimensional array over the first surface of the substrate, each light-emitting string (i) comprising a plurality of interconnected light-emitting elements spaced along the light-emitting string, (ii) having a first end electrically coupled to the first power conductor, and (iii) having a second end electrically coupled to the second power conductor, wherein the power conductors supply power to each of the light-emitting strings;
a plurality of conductive traces disposed over the first surface of the substrate and each (i) electrically interconnecting two light-emitting elements, or (ii) electrically connecting a light-emitting element to a power conductor; and
a polymeric top housing disposed over the first surface of the substrate and sealed to the first surface of the substrate at a contact point between the top housing and the first surface of the substrate to form a sealed region between the top housing and the substrate, the sealed region containing therewithin the plurality of light-emitting strings, the plurality of conductive traces, at least a portion of the first power conductor, and at least a portion of the second power conductor,wherein the lighting system is separable, via a cut spanning the first and second power conductors and not crossing a light-emitting string, into two individually operable partial lighting systems each comprising (i) one or more light-emitting strings, (ii) portions of the first and second power conductors configured to supply power to and thereby illuminate the one or more light-emitting strings of the partial lighting system, and (iii) a sealed region defined by a seal between a portion of the top housing and the substrate.
