First Claim
Patent Images
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 electrically connected to said grid of LEDs and having previously been electrically connected to the removed said at least one LED;
aligning an opening of a compensating unit at least partially with said grid opening; and
mechanically coupling said compensating unit to said free wire segments;
wherein said compensating unit is configured to alter current within said grid of LEDs to lessen the effect of increased current due to the removal of said at least one LED.

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.

10. A method for compensating a cut-out of LEDs and associated wiring in an LED-based lighting unit, comprising:
-
identifying removal of at least one LED from a plurality of LEDs of said LED-based lighting unit, said LEDs connected in a series parallel configuration by conductive wiring; wherein removal of said at least one LED increases current supplied to at least one group of LEDs connected in parallel with one another relative to an original current supplied to said at least one group of LEDs prior to removal of said at least one LED;
determining a current alteration necessary to lessen current supplied to said at least one group of LEDs to a current level substantially similar to said original current; andapplying said current alteration to said at least one group of LEDs. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
