Abstract: A lighting assembly includes a plurality of LEDs mounted on a flexible substrate such as a printed circuit board. The printed circuit board is bonded thermally and physically to a thicker, rigid substrate, such as a metal plate, to form a board assembly. The rigid substrate is made of a thermally conductive material, such as aluminum. As such, the board assembly provides structural rigidity and thermal conductance. Bonding the metal plate to the printed circuit board also provides improved thermal communication over the entire overlapping areas of the metal plate and printed circuit board. The board assembly is fastened to a heat exchanging device, such as an evaporator. The rigid substrate of the board assembly provides continuous contact of the substrate with the heat exchanging device in response to a reduced number of fastening points.
