ABSTRACT:
An LED-based lighting system includes a printed circuit board (“PCB”) having conductors on a front-side thereof, one or more LEDs mounted with the conductors, and a structural element. The PCB is mounted with the conductors near to the structural element so that heat dissipation from the LEDs is primarily through the conductors and the structural element. A method of dissipating heat generated by an LED-based lighting system includes configuring a PCB with conductors on a front-side of the PCB, such that when one or more LEDs mounted to the conductors generates heat, the heat dissipates from the one or more LEDs to the conductors. The method also includes integrating a structural element such that at least portions of the conductors face the structural element, and the heat dissipates from the conductors to the structural element.
