Abstract:
Methods and apparatus related to compensating for electrical changes resulting from cut-out of a portion of a grid of a plurality of LEDs (20A-T; 120; 220; 320). A compensating unit (40; 140; 240; 340) may be coupled to free wire segments of the grid that are created by the cut-out and the compensating unit (40; 140; 240; 340) may be configured to alter current supplied to remaining LEDs of the grid of LEDs. The compensating unit is configured to and/or may be configured to lessen current supplied to one or more LEDs of an LED-based lighting unit.
