As the temperature of the board climbs, the LED will receive less power. The high-density heating of the disc is conducted through the extrusion to a larger area of the surface. A positive temperature coefficient heating element (PTC heating element) or self-regulating heater is an electrical resistance heater whose resistance increases significantly with temperature. They have most characteristics the same, but the OP is interested in the difference between them. I've seen at least one ovenized oscillator (where a tiny oven is used to keep one component at a very specific temperature) that simply used a resistor as the heating element. When power is first applied to the cold PTC heating element, it has a low resistance and draws a large amount of current.
