Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for compensating a cut-out of LEDs and associated wiring in an LED-based lighting unit, comprising: removing at least one LED from a grid of LEDs to create a grid opening in the grid of LEDs, said grid of LEDs connected in a series parallel configuration by conductive wiring; wherein removing said at least one LED disjoins portions of said wiring and creates a plurality of free wire segments in said wiring, said free wire segments electrical…
