Claim of US Patent No. 10,342,082

1. A flexible strip of linear lighting, comprising:a narrow, elongate, flexible printed circuit board (PCB) physically and electrically arranged in a plurality of repeating blocks, each of the one or more repeating blocks being arranged electrically in parallel with one another between power and ground, and each of the plurality of repeating blocks including
electrical connections to receive high-voltage alternating current (AC) power,
a power conversion and conditioning circuit including at least a full-bridge rectifier mounted on the PCB and connected to the electrical connections that converts the high-voltage AC power to direct current (DC) power,
a plurality of LED light engines electrically connected to the power conversion and conditioning circuit to receive the DC power, and
a filter connected to the plurality of LED light engines, the filter being adapted such that each of the plurality of LED light engines has a flicker percentage of 70% or lower when each of the plurality of repeating blocks is connected to the high-voltage AC power through an electronic low voltage dimmer at a dimmer setting of 100%;
a pair of conductors traversing the length of the flexible PCB to provide the power and the ground for each of the plurality of repeating blocks, the pair of conductors adapted to carry the high voltage AC power and being connected to the high-voltage AC electrical connections for each of the plurality of repeating blocks; and
a transparent, flexible, electrically insulative covering around the printed circuit board and the pair of conductors, the covering providing a separate, electrically-insulated space for each of the pair of conductors.
