SYSTEMS AND METHODS FOR COUPLING A METAL CORE PCB TO A HEAT SINK
First Claim
Patent Images
1. A heat sink for a light fixture comprising:
- a plurality of fins positioned from a first end of the heat sink to a second end of the heat sink, the plurality of fins having a fin width positioned perpendicular to a central axis of the heat sink;
a base being coupled to lower surfaces of the plurality of fins, the base being comprised of metal core PCB, wherein the base does not cover an entirety of the lower surfaces of the plurality of fins;
orifices extending through the base, the orifices having an orifice length extending in a direction from the first end of the heat sink towards the second end of the heat sink, the orifice length being greater than an orifice width, wherein the orifices expose the central axis of the heat sink.

Abstract
Embodiments may utilize a series of exposed fins, which increase the surface area of the heat sink creating additional air flow. As hotter air rises within the system, cooler is drawn into the heatsink. The fins may be exposed on both sides of the longitudinal axis, allowing cooler air to be drawn towards the longitudinal axis above the heatsink and flow upward. This process may cool the fins. Additionally, the spacing between the fins may have to be wide enough to allow for air to freely enter the heatsink.
