Abstract:
1. A light-emitting diode (LED) package, comprising: a thermally-conductive heat-sinking body comprising first and second opposing surfaces, the first and second surfaces having first and second surface areas, respectively, the second surface area exceeding the first surface area; an LED device comprising a bottom surface, a light-emitting element, a first contact point, and a second contact point, the first and second contact points being configured to provide electrical current to the LED device, the bottom surface being attached to the first surface and thermally connected thereto; a first electrical trace comprising an electrically conductive material disposed on the first surface and electrically insulated therefrom, the first trace comprising a first proximal end and a first distal end; a second electrical trace comprising an electrically conductive material disposed on the first surface and electrically insulated therefrom, the second trace comprising a second proximal end and a second distal end; a first electrically conductive path connecting the first contact point and the first proximal end; a second electrically conductive oath connecting the second contact point and the second proximal end; an optically transparent encapsulating cap disposed over the LED device and encapsulating same, the encapsulating cap further covering at least the first proximal end, the second proximal end, the first electrical contact, and the second electrical contact, and a circuit board having top and bottom surfaces and a hole disposed therethrough; wherein the LED package is electrically coupled to the printed circuit board, the first and second distal ends of the first and second traces are electrically connected to corresponding first and second electrical conductors disposed on the printed circuit board, at least portions of the LED device are aligned with the hole and visible therethrough, at least portions of the LED package are coupled to the bottom surface of the printed circuit board, at least portions of the first surface of the heat sinking body are located adjacent to the bottom surface of the printed circuit board, and the second surface of the heat sinking body is not in contact with the bottom surface of the printed circuit board.
