1. An LED (light-emitting diode)-based lighting system, comprising:

  • a PCB (printed circuit board) having conductors on a front-side thereof, the conductors occupying at least 50% of a front-side area of the PCB;

    one or more LEDs mounted with the conductors; and

    a structural element comprising a metal rail that forms a corresponding aperture in one to one relationship with each of the one or more LEDs, such that each of the one or more LEDs is centered within its corresponding aperture;

    the PCB being mounted with the conductors proximate to the structural element so that heat generated by the one or more LEDs primarily dissipates through the conductors and the structural element.
