Flexible high-power led lighting system

A light engine comprising:

• a flexible cord comprising an electrical wire and an insulating material for the wire;
• a heat sink;
• a PCB in contact the heat sink, the PCB including a first surface having circuitry and a second surface opposite the first surface, the circuitry being in electrical communication with the cord;
• an LED mounted to the first surface of the PCB and in electrical communication with the circuitry;
• and
• a thermally conductive material contacting at least a portion of the first surface of the PCB and at least a portion of the heat sink for providing a thermal path from the first surface of the PCB into the heat sink.

A light engine comprising:

• a PCB including an upper surface, a lower surface and circuitry disposed on the upper surface;
• an LED disposed on the upper surface of the PCB and in electrical communication with the circuitry;
• a flexible cord comprising at least two wires and an insulating material for the wires, the at least two wires being in electrical communication with the circuitry, the cord being configured communicate with an associated power source and an associated signal generator, at least one of the wires being configured to deliver voltage to the LED to illuminate the LED and at least one of the wires being configured to deliver an electronic signal to the LED;
• a heat sink including an upper portion defining a generally planar lower surface and a second portion disposed underneath the upper portion and defining a generally planar upper surface, the generally planar lower surface being disposed adjacent the upper surface of the PCB and the generally planar upper surface being disposed adjacent the lower surface of the PCB;
• and
• a thermally conductive material contacting at least a portion of the upper surface of the PCB and at least a portion of the generally planar lower surface of the upper portion of the heat sink for providing a thermal path from the upper surface of the PCB into the heat sink.
