Abstract:
1. An apparatus comprising: an array of light emitting diodes (LEDs), wherein the array of LEDs has one or more electrical contacts through which power is supplied to the one or more LEDs; one or more thermal pads, each thermal pad being disposed beneath one or more LEDs of the array of LEDs and thermally coupled to the one or more LEDs, wherein the one or more electrical contacts are located on a same side of the array of LEDs as the one or more thermal pads; a heat conductor disposed beneath and thermally coupled to the one or more thermal pads at one or more protrusions of the heat conductor; and a flexible printed circuit electrically coupled to the one or more electrical contacts, wherein the apparatus further comprises resin between the LEDs and the heat conductor for high-voltage tracking isolation between the one or more thermal pads and the one or more electrical contacts of the LEDs, wherein the one or more protrusions space the heat conductor apart from the one or more electrical contacts of the LEDs for the resin to fill in.
