Abstract
Solid state lighting devices and associated methods of thermal sinking are described below. In one embodiment, a light emitting diode (LED) device includes a heat sink, an LED die thermally coupled to the heat sink, and a phosphor spaced apart from the LED die. The LED device also includes a heat conduction path in direct contact with both the phosphor and the heat sink. The heat conduction path is configured to conduct heat from the phosphor to the heat sink.
Claims20
A solid state lighting (SSL) device, comprising:
- a substrate;
- an SSL die carried by the substrate, the SSL die including an emissions area;
- a partially transparent layer of thermal insulator material encapsulating and in direct contact with the SSL die;
- a monolithic layer of conduction material encapsulating the SSL die, the conduction material in direct contact with the substrate in a region laterally adjacent to the SSL die;
- a converter material disposed over the monolithic layer of conduction material and positioned in line with the emissions area of the SSL die such that emissions from the SSL die are configured pass through the converter material.
