Assignee: COOLEDGE LIGHTING INC.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  F | IPC F  H

Claim 60:
61. A lighting system comprising:
a lightsheet comprising:
a substrate;
disposed on the substrate, (i) first and second spaced-apart power conductors and (ii) a plurality of conductive traces;
a plurality of light-emitting strings, 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 the light-emitting strings; and
one or more control elements each configured to control current to one or more of the light-emitting strings,

wherein (A) at least one control element comprises a first transistor, a second transistor, a first resistor, and a second resistor, and (B) the lightsheet is separable, via a cut spanning the first and second power conductors and not crossing a light-emitting string, into two partial lightsheets each comprising (i) one or more light-emitting strings, and (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 lightsheet.
