US Patent 10066792 Serial and parallel LED configurations for linear lighting modules

A linear lighting module includes a first string of series-connected LED dies and a second string of series-connected LED dies. The first string of LED dies is coupled in parallel with the second string of LED dies. All of the LED dies of the first and second strings are aligned with respect to one another. The LED dies of the first string and the second string form a combined string of interleaved LED dies such that an LED die of the second string is disposed between every successive pair of LED dies of the first string. The LED dies of the combined string are mounted on a flexible substrate. Each LED die of the combined string is electrically connected to two conductors. Except for the two end LED dies of the combined string, each successive LED die must be accessed by both conductors from alternating sides of the combined string.
