ABSTRACT:
A convection cooling system for high-output Light Emitting Diodes in outdoor illumination applications. The cooling system takes advantage of wide-angle LED output so as to allow placement of cooling fins directly on the shaded underside of the molded or extruded support structure. Accordingly, the cooling system provides a relatively large convective surface area with a substantial portion of that surface shaded from solar radiation so as not to collect solar heat during daytime periods while still expelling heat as it is collected from finned portions that are exposed to sunlight and so do collect solar heat.
