  • Patent number: 12181132
    Abstract: Rack-type backlight light emitting element (LEE) printed circuit boards (PCBs) with at least two layers to provide redundant current paths. This enables a PCB strip to be broken at designated perforations in the field in order to accommodate pipes or fixtures that require formation of a gap in the rack array. The entire length and width of an array can be sized in the field. A plurality of PCB arrays can be serially chained together with the system. A chain of PCB strips is snapped into clips, which in turn snap into rails that are fastened to a surface. The mounting system includes various types of clips, such as end clips, clips for different LEE patterns on the PCBs, and mounting clips to secure the rails to a surface.

  • Patent number: 11193635
    Abstract: 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.
