Abstract
Flexible light engines capable of being cut, and methods thereof, are provided. A cuttable flexible light engine includes a flexible strip and strings of solid state light sources coupled in parallel. A voltage balancer establishes a desired current flow through the strings of solid state light sources when the flexible strip is cut to a desired length, and may be part of a connector placed where the strip is cut. The strings may be provided in a first set of strings coupled in parallel between a first conductive path and an intermediate conductive path and a second set of strings coupled in parallel between the intermediated conductive path and a second conductive path. A cuttable flexible light engine may also include test points positioned within the strings.
