Abstract
An LED array is mounted on a base that is thermally coupled to a heat spreader. At least one aperture is provided between the support area and an edge of the heat spreader. The heat spreader may be coupled to a thermal pad which has sufficient thermal conductivity and is sufficiently thin to allow the thermal resistivity between the heat spreader and a corresponding heat sink to be below a predetermined value.
Claims12
A light module comprising:
- a light emitting diode (LED) array defining a first area, the LED array including an anode and a cathode;
- a heat spreader including a support region with a second area that supports and is thermally coupled to the LED array, the heat spreader having an outer edge and further including an aperture positioned between the outer edge and the support region, the heat spreader defining a third area;
- a conductor extending through the aperture, the conductor configured to be coupled to one of the anode and the cathode, wherein the thermal resistance between the LED array and the heat spreader is less than two (2) degrees Celsius per watt (C/W).
