US Patent 11193635 Flexible and cuttable LED sheet

LED lighting sheets feature foldable light-sheets including multiple illumination modules electrically interconnected such that unremoved illumination units remain energized upon removal of one or more by horizontal, vertical and or diagonal cuts. A new and non-obvious conductor geometry forms a 3D mesh that is resistant to cutting from any direction in 45 degree increments. Relatively constant illumination levels are maintained in the remaining LEE's by using relatively high resistance series connected current limiting resistors for each LEE. Each current limiting resistor may be, for example, ten times the resistance of the entire lower ribbon conductive layer. Tunable color LEE's are included.
