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.

Abstract: A reflector system having two-axis control through which beam collimation and wide-angle beam overlapping occur, and a method of manufacturing such a system through cutting flat reflective sheeting and forming the resultant flat parts into the three-dimensional reflectors that collect and shape the light from solid state LEDs, wherein each axis may be customized by changing the cutting and bending of the flat pieces.

Abstract: An internally expanding and locking apparatus for installing inside the pipe stub of a typical outdoor lighting pole and expanding with locking teeth to grasp the inner walls of the pipe stub, the apparatus including a swivel base, a clamp screw inserted through the swivel base, a ramp nut passing over the clamp screw so as to be positioned offset from the swivel base, and a mounting nut threadably installed on the clamp screw and configured to engage the ramp nut so as to control the position of the ramp nut relative to the swivel base as the clamp screw is rotated during use of the pipe mounting apparatus.
